There is a way to go to the black hole, but it is not possible to come back ‘!!!!!!!!!!!!!!

Two physicists have figured out the conditions necessary to enter the black hole. Black holes are so mysterious that scientists are very keen to know about them. Scientists say that going to a black hole would be a one-way trip, because if the light could also come out from the black hole, then it is useless to predict the possibility of a human coming out. Small black holes do not rotate and the radius of their event horizon is very low. This is the place, after which nothing comes back.

An event horizon means that the event horizon is a boundary beyond which the events beyond it cannot have any effect on the universe outside its boundary, nor can any person sitting outside its boundary know what is beyond the boundary. Used to be.

Here the effect of gravity is very high. Apart from this, the radius of the event horizon of the second massive black hole is 7.3 lakh miles. There is a difference of thousands of billion times in gravity between the center of both and the event horizon. If a star-related object crosses the black hole’s event horizon, it undergoes a process of sphagatification.
Sphagetification is the process by which (in some theories) an object falling into a black hole will be separated or ripped off by gravitational forces. In this, every molecule of its body is pulled by a long strand. This happens because the gravity at one point in space time is much higher than the other point. When this happens, it is impossible to survive in a black hole.

However, if a person falls into a massive black hole, he will be in freefall and there will not be spaghettification. The reason behind this is that the distance between the black hole from the event horizon is much more.

Budget Session to See New Bill Banning Bitcoin in India, May Make Way for Official Digital Currency Issued by RBI

The budget session of Parliament is all set to introduce a new bill that bans private cryptocurrencies and provides for an official digital currency to be issued by the Reserve Bank of India.

The Union Budget, which will be presented on February 1, is looking towards the introduction, consideration, and passing of the Cryptocurrency and Regulation of Official Digital Currency Bill. Apart from prohibiting all private cryptocurrencies in India, the bill also seeks to create a facilitative framework for an official digital currency issued by the RBI. However, as per a Lok Sabha bulletin, the bill allows for certain exceptions to promote the underlying technology of cryptocurrency and its uses. In 2018, the Indian central bank had banned crypto transactions after a number of frauds came to the fore following PM Modi’s decision to ban 80% of the nation’s currency. As a result, the Cryptocurrency trade was brought to a halt after the RBI asked all regulated entities, such as banks, to stop any dealings related to private cryptocurrencies as part of that order.However, the table’s turned when a supreme court bench, headed by Justice Rohinton F Nariman, quashed the central bank’s circular on grounds of disproportionality.

According to a report by Bloomberg, the court ruled that RBI had failed to show “at least some semblance of any damage suffered by its regulated entities’’ to back its decision to effectively bar cryptocurrencies in India.” From then Cryptocurrency exchanges began operations yet again.

The rapid surge in the price of Bitcoins accelerated its use by top banks, which had stopped dealing with cryptocurrency exchanges after the RBI’s order. The dealings with the cryptocurrency became a point of global debate. Large Investment houses said that Bitcoins can be seen as an alternative to gold. JPMorgan said that “a crowding out of gold as an ‘alternative’ currency implies big upside for bitcoin over the long term.” Earlier this week, Bridgewater Associates founder Ray Dalio said Bitcoin is “one hell of an invention” and added that he is considering cryptocurrencies as investments for new funds offering clients protection against the debasement of fiat money. To further this cause, payment networks such as Paypal, MasterCard, and Visa also moved to set up systems that accept payments via cryptocurrencies.

Also, this week, the RBI had reiterated that it was exploring the need for a digital version of the fiat currency.

Government lists bill to ban Bitcoin in India, create official digital currency

(An RBI booklet on payment systems issued on 25th Jan also showed that the central bank is exploring whether to issue a digital version of the rupee)

In the legislative order of business for the budget session of 17th Lok Sabha that commenced today, the Government has listed a bill providing for the banning of all private cryptocurrencies in India such as bitcoin, ether, ripple and others. The bill also provides for the creation of a legislative framework on an official digital currency.

An RBI booklet on payment systems issued on 25th Jan also showed that the central bank is exploring whether to issue a digital version of the rupee. “Private digital currencies have gained popularity in recent years,” the central bank booklet said. “In India, the regulators and governments have been sceptical about these currencies and are apprehensive about the associated risks.

Nevertheless, RBI is exploring the possibility as to whether there is a need for a digital version of fiat currency and, in case there is, how to operationalize it,” it noted. A previous RBI ban on the use of bank channels for payments associated with cryptocurrency issued in 2018 was overturned by the Supreme Court in March 2020 creating a vacuum in the regulation of cryptocurrency in India.

Bitcoin alternative: How to buy Ethereum in India? Here’s why its price, m-cap are up 200% in 3 months

Following Bitcoin and Ethereum, the other leading cryptocurrencies based on the market cap are Tether ($24.8 billion), Polkadot ($16.1 billion), XRP ($12.4 billion), Cardano ($11.2 billion), Chainlink ($9.7 billion), Litecoin ($9.3 billion), Bitcoin Cash ($8.2 billion), and Binance Coin ($6.4 billion).

Cryptocurrency king Bitcoin’s closest rival Ethereum has scaled up from $414 price with a market cap of $46.8 billion to $1,323 and $151.4 billion in market cap – a 219 per cent increase in price and 223 per cent jump in valuation in the past three months, according to the data from CoinMarketCap.

Despite being the biggest alternative to Bitcoin, Ethereum doesn’t even come close to bitcoin’s craze and market cap. However, it has managed to create significant buzz around investors. It has drawn the attention of blockchain stakeholders for its use beyond just processing crypto transactions. Ethereum has so far been used for enabling the deployment of smart contracts and decentralized apps to be created and operated without any fraud or interference from third parties, unlike Bitcoin.

The growing popularity, rising valuation, a growing number of exchanges offering Ethereum, and more have been among the reasons for investors flocking to it. Ethereum’s market cap has jumped over 200 per cent in the past three months.

Source: CoinMarketCap In order to buy Ethereum, one can register on one of the crypto exchanges such as BuyUCoin, CoinDCX, Unocoin, and more. Completing KYC and/or anti-money laundering norms are mandatory for Indian jurisdiction. Along with this, the Aadhaar-linked mobile number is also necessary.

One can further secure his/her Ethereum wallet with Google’s 2-step verification following which bank account details have to be added to begin trading Ethereum in India with INR currency. As a user, one can set his/her monthly or weekly, or even daily targets and decide the markets you would want to trade. Be certain of how much risk you are willing to take on every trade and based on it, figure out your risk-reward ratio.

Apart from INR, one can also buy Ethereum with credit and debit cards, UPI, or bank transfers, etc.Following Bitcoin and Ethereum, the other eight leading cryptocurrencies in the top-10 list based on the market cap are Tether ($24.8 billion), Polkadot ($16.1 billion), XRP ($12.4 billion), Cardano ($11.2 billion), Chainlink ($9.7 billion), Litecoin ($9.3 billion), Bitcoin Cash ($8.2 billion), and Binance Coin ($6.4 billion), as per CoinMarketCap. Bitcoin, at the time of filing this report, was trading at $32,305 with a jaw-dropping market cap of $606 billion. Posted by Technical Mechzone

Google says it will shut search engine in Australia if forced to pay for news

SYDNEY – Google said on Friday it will disable its search function in Australia if the government proceeds with a media code that would force it and Facebook Inc to pay local media companies for sharing their content. Australia is on course to pass laws that would make the Big Tech giants negotiate payments with local publishers and broadcasters for content.

If they can’t strike a deal, a government-appointed arbitrator will decide the price. The code’s arbitration model with bias criteria presents unmanageable financial and operational risk for Google,” Mel Silva, managing director for Australia and New Zealand, told a senate committee. “If this version of the code were to become law, it would give us no real choice but to stop making Google Search available in Australia Google’s comments drew sharp rebuke from Australian Prime Minister Scott Morrison who said the country makes its rules for “things you can do in Australia.” “People who want to work with that in Australia, you’re very welcome. But we don’t respond to threats,” Morrison told reporters. The United States government this week asked Australia to scrap the proposed laws, which have broad political support, and suggested Australia should pursue a voluntary code instead. Australia announced the legislation last month after an investigation found Alphabet Inc-owned Google and social media giant Facebook held too much market power in the media industry, a situation it said posed a potential threat to a well-functioning democracy. Google’s threat to limit its services in Australia came just hours after the internet giant reached a content-payment deal with some French news publishers. Google’s testimony “is part of a pattern of threatening behaviour that is chilling for anyone who values our democracy,” said Peter Lewis, director of the Australia Institute’s Centre for Responsible Technology.

Astrosat satellite spots ‘dinosaurs of the universe’ globular star cluster:

(The team of scientists found about 34 UV-bright stars were found to be members of the globular cluster.)

Astronomers, with the help of India’s first multi-wavelength space satellite Astrosat, have spotted a massive intriguing globular cluster in the Milky Way galaxy with rare hot UV-bright stars in it, the Department of Science and Technology said on Thursday. These stars whose inner core is almost exposed, making them very hot, exist in the late stages of evolution of a Sun-like star.

It is not clear how these stars end their lives as not many of them are detected in these fast-evolving phases, making their study crucial. The old globular clusters referred to as dinosaurs of the universe, present excellent laboratories where astronomers can understand how stars evolve through various phases between their birth and death with spectacular ultraviolet images of the cluster from Ultraviolet Imaging Telescope (UVIT) on board. Astrosat satellite spots dinosaurs of the universe globular star cluster: Dept of Sci-technical The old globular clusters present excellent laboratories where astronomers can understand how stars evolve through various phases between their birth and death.

Image credit: Wikipedia/Richard Hook, ESO With AstroSat, astronomers from the Indian Institute of Astrophysics, an institute of the Department of Science and Technology, distinguished the hot UV-bright stars from the relatively cooler red giant and main-sequence stars which appear dim in these images.

The findings of this study have been accepted for publication in ‘The Astrophysical Journal’. The team of scientists comprising Deepthi S Prabhu, Annapurni Subramaniam and Snehalata Sahu from IIA combined the UVIT data with observations made using other space missions such as the Hubble space telescope and the Gaia telescope along with ground-based optical observations were also used. About 34 UV-bright stars were found to be members of the globular cluster.

From the data, the team derived the properties of these stars such as their surface temperatures, luminosities and radii. “One of the UV-bright stars was found to be about 3,000 times brighter than the Sun with a surface temperature of about 1,00,000 kelvin,” Subramaniam said.

Buying Bitcoin is the most crowded trade; reminiscent of the 2018 crash

Experts are warning of a bubble building up in Bitcoins, especially considering the sudden spike in volatility and increasing institutional participation The latest global fund manager survey published by BofA Securities showed that buying Bitcoin is being viewed as the most “crowded trade”.

After Bitcoin’s massive rally in recent months, it is hardly surprising that this cryptocurrency is fast regaining its lost glory. From a low of $4,000 in mid-March last year, the price of the world’s first and most famous cryptocurrency has risen by nearly 900%.

Currently, Bitcoin is trading at $34,750. Long Bitcoin jumps to top with 36% of fund manager survey investors saying it is the most “crowded trade” dethroning “Long tech” for the first time since October 2019,” said the survey report. “Investors who have been tracking Bitcoins in the past would recollect that a similar rally in 2017 was followed by a crash. In 2017, Bitcoin rallied from the low of around $790 to a peak of $1,9041 in December. Interestingly, in the December 2017 BofA survey, Bitcoin topped the list of most crowded trades.

In 2018, it crashed by 74%. Even now, many experts have been warning of a bubble building up in Bitcoins, especially considering the sudden spike in volatility and increasing institutional participation. “Most cryptocurrencies are notoriously volatile, and the increase in institutional participation may be making things worse.

While demand would increase and volatility ease should corporations hold Bitcoin for business purposes, the opposite is true when institutions gain exposure for speculative purposes. Empirical evidence from other asset classes suggests that higher participation by institutional investors could increase volatility due to their more opportunistic investment approach,” Michael Bolliger, chief investment officer, global emerging markets, UBS Switzerland AG said in a report on 14 January.

Ultimately time will tell what holds true for Bitcoin investors but those in the bullish camp see further upside. For instance, according to JPMorgan Chase & Co, Bitcoin has the potential to reach $146,000 in the long term as it competes with gold as an asset class. Posted by Technical Mechzone

Bitcoin (BTC/USD) Forecast

Bitcoin sell-off a threat to major cryptocurrencie Bitcoin prices have rebounded slightly, following a sell-off from Friday’s high, where BTC/USD broke above $40,000, before facing a wall of resistance formed by the key psychological level of $42,000.

The three day sell-off resulted in a $10,000 depreciation in the digital currency, raising concern that the Bitcoin ‘bubble’ had officially burst. However, the pullback in prices is no comparison to the massive 949% surge from March 2020 low. Bitcoin TradingBitcoin Trading Meanwhile, fundamental factors appear to be influencing price action, with Bitcoin recently portraying the same characteristics as Gold, Silver and other safe-haven assets, which benefit from US Dollar weakness. On the regulatory front, additional drivers of price action have been attributed to warnings from both the New Zealand and UK regulators (FMA & FCA respectively) who have cautioned individuals against trading Bitcoin and other digital currencies.

BITCOIN (BTC/USD) TECHNICAL ANALYSIS After plunging approximately 11% in yesterday’s trading session, Bitcoin bulls were able to bounce off trendline support, pushing price action to a zone of resistance, formed by the 23.6% Fibonacci retracement (between November 2020 low and January 2021 high) at $35,866. The 20-period Moving Average (MA) continues to provide additional support, while the Relative Strength Index (RSI) now rests beneath 70, indicating that BTC/USD may be exiting overbought territory. Building Confidence in TradingBuilding Confidence in Trading What does it take to be a confident trader? . Get My Guide Bitcoin (BTC/USD) Daily Chart If bulls are able to break above current resistance, a bullish continuation could be probable, with the potential retest of $40,000. However, if bears are able to drive prices lower, a break below current support, could bring the 50% Fibonacci retracement into focus at $29,023 BITCOIN (BTC/USD) SENTIMENT Bitcoin (BTC/USD) Bulls Bite the Bullet How to Use IG Client Sentiment in Your TradingHow to Use IG Client Sentiment in Your Trading RECOMMENDED BY Technical Mechzone How to read client sentiment Get My Guide At the time of writing, retail trader data shows 84.05% of traders are net-long with the ratio of traders long to short at 5.27 to 1.

The number of traders net-long is 7.02% higher than yesterday and 16.14% higher from last week, while the number of traders net-short is 15.08% lower than yesterday and 20.86% lower from last week. We typically take a contrarian view to crowd sentiment, and the fact traders are net-long suggests Bitcoin prices may continue to fall. Traders are further net-long than yesterday and last week, and the combination of current sentiment and recent changes gives us a stronger Bitcoin-bearish contrarian trading bias.

After dizzying gyrations, what’s bitcoin really worth?

The virtual currency barrelled to new highs to rise more than 400% over the past year, before promptly sliding some 20% and then settling around $36,000 After the latest wild ride took the poster child of cryptocurrencies above $40,000 before a stomach-churning plunge, the million dollar question won’t go away: how much is bitcoin actually worth? The virtual currency barrelled to new highs to rise more than 400 percent over the past year, before promptly sliding some 20 percent and then settling around $36,000. When it started life in 2009 as open-source software, bitcoin was essentially worth zero — though within a year it had reached the heady heights of eight cents. At today’s market rates, bloated by a surge in institutional demand, the digital unit’s market capitalisation is worth some $670 billion with myriad other crypto coins such as ethereum lifting the sector nominally close to the trillion mark. Although that’s small potatoes compared to the $68 trillion or so swilling around world stock markets, it is nonetheless the sort of financial territory staked out by Wall Street tech royalty such as Google, Apple or Tesla. One tech site, AssetDash.com, notes that bitcoin is currently worth around as much as Facebook and a little more than Chinese e-retail giant Alibaba Although deep-pocketed investors have recently become enthusiasts, crypto was in its early days the preserve of geeky amateur investors. It is the latter who have mainly suffered as an estimated four million of the roughly 19 million bitcoin units currently in circulation have been lost. “Lost” does not mean the coins have fallen down the back of the sofa or through a hole in a trouser pocket: they have been electronically zapped from the record, often because their owner has forgotten a password to coins hoarded on a USB stick. One US developer mislaid his password after storing 7,002 bitcoins on one such flash drive, forcing him to wave goodbye, on paper (or rather, the trading screen), to around $280 million. This week, Welshman James Howells desperately offered his local authority a quarter of his fortune to dig up a landfill site where he believes a hard drive he accidentally tossed away — and which has since soared in value to around $270 million — is buried.

The council refused, citing the cost and logistical restrictions. According to analysts at JP Morgan, bitcoin may be highly volatile but could go as high as $146,000 per unit, putting it in competition with gold as an asset class in terms of private sector investment. That volatility, as well as the unregulated and decentralised nature of the bitcoin beast, are key reasons why many seasoned financial observers are scared off — as well as the risk of “losing” their stash. “Most of the lost bitcoins were acquired in the early days,” said Philip Gradwell, economist with Chainalysis. Gradwell said that around one in five bitcoins in circulation today have not budged from their location in five years — since days when the unit was worth not much more than $100. “One or two million of those belong to Satoshi himself,” added Gradwell, referring to the creator of the coin, whose identity remains unknown. He added that the bulk of investors are not day-to-day traders, but people making a long-term punt — and he estimates that the spectacular price boom of recent weeks has involved only around five millions units. Patrick Heusser, head of trading at Swiss trader Crypto Broker, said that following the trading volumes of a variety of cryptocurrencies, rather than just bitcoin, would give a better idea of how the market is faring. “Ethereum has a lot of activity on the chain, but on the litecoin side there is almost nothing going on,” said Heusser, with the former valued at some $138 billion currently, and the latter at $10 billion. Heusser suggested the rises have been largely a bitcoin slipstream effect, and he cautioned against drawing parallels with gold. “To be honest I don’t believe that it is a very powerful or insightful metric inside what’s going on in the crypto market,” Heusser concluded. After years of experience on traditional currency markets, he judged that it was early days for the crypto equivalent. Posted by Technical Mechzone
