Black Holes In Pics: Some fun facts about them from NASA

1/5 Did you know there are two kinds of black holes? Yes, you read that right! According to NASA, black holes can be differentiated into two depending on their mass. The first is a Stellar Black Hole which is formed from a single star. It can be three times the size of our Sun. The other is a Supermassive Black Hole which forms due to merging of other black holes. It is a massive black hole which resides in the center of galaxies and is capable of engulfing other stars.

2/5 How many black holes are there? Well, according to NASA, there are hundreds of black holes in space. However, scientists assume that black holes are present in thousands. (NASA)

4/5 Is there a supermassive black hole in our galaxy? Yes, there is! Located nearly 26,000 light years away at the center of our Milky Way Galaxy is Sagittarius A*, the supermassive black hole which could potentially one day swallow the whole Milky Way Galaxy. (NASA)

5/5 Can our Sun become a black hole? The answer is no. According to NASA, a black hole forms from a star that is nearly 15 to 20 times the size of our Sun. So, you need not worry about being swallowed by our own Sun. So, when our Sun eventually runs out of fuel, it will become a white dwarf and expand in size, turning into a red giant. (Pixabay)

What happened after the initial Big Bang explosion? Know what various experts have to say. (NASA)

Big Bang, the colossal explosion which triggered the formation of our universe, occurred nearly 13.7 billion years ago. After that, it actually took millions of years for the formation of the Earth. This theory, known as the Big Bang theory, was proposed by an astronomer named Georges Lemaitre in 1927, though there are questions still unanswered today. What were the conditions like during the early days of the Big Bang? How did Earth terraform into the planet as we know it today? What really happened during the Big Bang?

According to the Big Bang theory, the universe started as just a single point, known as a Singularity. The universe stretched and expanded to get as big as it is now, and it is still expanding a little bit every single day. However, this might not entirely be true as this singularity is based on Albert Einstein's theory of general relativity, according to

The tech that caught it all

Understanding all of this is not at all possible without the technology and the gadgets that go along with it. NASA's Cosmic Background Explorer satellite and Wilkinson Anisotropy Microwave Probe reported observations of microwave light just 400,000 years after the Big Bang, according to the space agency. NASA says that after the initial explosion, darkness prevailed in the universe for a long time until 100 million years later when the first glimpse of visible and UV light occurred. This light was captured in data form by another one of NASA's awesome gadgets, the Spitzer Space Telescope.

What do experts say?

Published on, Sean Carroll, a theoretical physicist at Caltech said, “The problem is, there's no reason whatsoever to believe general relativity in that regime. It's going to be wrong, because it doesn't take into account quantum mechanics. And quantum mechanics is certainly going to be important once you get to that place in the history of the universe.”

The universe expanded nearly 100 times its size in a span of fraction of a second, known as Inflation. Alex Filippenko, astrophysicist at the University of California, Berkeley told, “Inflation was the 'bang' of the Big Bang. Before inflation, there was just a little bit of stuff, quite possibly, expanding just a little bit. We needed something like inflation to make the universe big.”
