Blackhole: Humanity & Science

Is it possible that time starts moving differently for a person or time stops completely or is it possible that we are living in multiverse and not in universe and people like us are different in another universe? Are you living in a dimension?

In thinking all these things seem like some fiction or Hollywood ‘sci-fi’ movies, but this universe is actually more mysterious than any fiction. And one such mystery is Blackhole.

Despite a blackhole being scary, interesting and strange, today there is such a reality of the universe that has forced all the astro-physicists of the world to think that how does this universe work? Are the laws we have set about physics true or false?

More recently, scientists associated with the ‘Event Horizon Telescope’ project have released the first images of a ‘black hole’ located at the center of our Milky Way galaxy. This picture of the ‘black hole’ being referred to has proved that Einstein’s theory of space-time was completely correct, in which he hypothesized that “there may be centers in the universe where all space-time” Time runs out and turns into a “singularity”.

The black hole ‘Sagittarius A*’ at the center of our galaxy has a mass of 4 million times the mass of our Sun and is located at a distance of 26,000 light-years from Earth. Will reach the black hole in twenty six thousand years.

Actually blackholes are the most mysterious because the mass of the blackhole is infinite, not even light can escape from the blackhole’s sphere of influence, but a supermassive blackhole also exhausts the space-time around it i.e. the basic infrastructure from which our universe is made, blackhole can end them all.

Then again the question arises that when a black hole destroys everything, then how can its picture be taken?

But blackholes can be pictured because a disk is formed around the blackhole called an “accretion-disk” in which the matter spins very rapidly. Then there is a region around the blackhole called the “event horizon” which is It shines very brightly, because it has a temperature of millions of degrees Celsius and is the last black hole in the center which looks black because the light does not come back from it. If tried, they see intense brightness in the event horizon and there is a black area in the middle, scientists get information about the blackhole on the basis of these calculations. That is why the name of this telescope is also named Event Horizon Telescope.

In fact, the Event Horizon Telescope is made up of telescopes installed in Spain, the US and Antarctica, as well as eight radio observatories located around the world. In 2006, an international team of more than 200 researchers led by astronomers from Harvard University developed a ‘Black’ The ‘Event Horizon Telescope’ (EHT) project was started with the sole objective of taking a clear picture of the hole. Thirteen participating institutions together with the help of the already existing infrastructure and various agencies to build the ‘Event Horizon Telescope’ The job worked.

It is also believed about the black hole that it operates the galaxy along with the destroyer and some scientists also believe that our universe started only after the explosion of a black hole, along with this the theory like multiverse was born. It is also caused by blackhole. Today, black holes have given a new form to human imagination, as well as today, through anthropology, many steps have been taken in understanding this universe.
