Who wouldn't like to marvel at these space bodies that do not even let light escape? Ranks of scientists from Albert Einstein to Stephen Hawking have studied black holes but they remain to be completely understood.
Scientists continue to study black holes. Leo and Shanshan Rodriquez, both assistant professors of physics at Grinnell College compared two types of black holes, stellar-sized and supermassive. Stellar-sized black holes are roughly the size of the Sun while supermassive black holes can have a mass equal to four million Suns. Both these black holes have event horizon. It is the boundary line, the point of no return.
When anyone crosses the event horizon, the massive gravitational pull of the black hole takes over. It's not a good idea to try to enter stellar sized black hole as its event horizon is just a few kilometres long and closer to the centre of the black hole.
If an astronaut enters such a black hole he will undergo what's known as Spaghettification. This set comes with two eyepieces, a red dot finder scope, an image star diagonal, and a travel tripod.
Plus, it comes with helpful software so you can easily identify any stars and planets you see. The person would stay cognizant and intact for longer. But, of course, they would never emerge—making this a one-way rollercoaster ride of scientific discovery into oblivion.
Why does the math work this way? Why does stuff go in but never come out? Those black holes are very old, for example, with different physics than this special case. But, like in Interstellar , our imaginations reel at the idea of studying a black hole from the inside. Perhaps in some far future, someone will invent the right kind of tether to pull someone back out.
And in that case, we can confirm some of the facts of life in a black hole, time dilation or not. Type keyword s to search. Today's Top Stories. Devrimb Getty Images. Scientists say humans could indeed enter a black hole to study it.
The reason is that supermassive black holes are much more hospitable. You may be able to find the same content in another format, or you may be able to find more information, at their web site. Orion SkyQuest XT8. Remember, light cannot even escape a black hole—that is why it is called a black hole.
From an outside perspective, time would slow down as you moved closer to the center of the black hole. Time and space begin to warp and stretch as they are pulled towards the center of the black hole: this means that you too would warp and stretch.
This bending and stretching is called spaghettification. Someone outside the black hole would see your body begin to stretch and bend like a spaghetti noodle. As you approach the edge of the event horizon, you will freeze in space and time. You will appear to be unmoving and stretched like a noodle forever.
After some time, heat and radiation would then destroy your body and turn you into ash. However, time becomes strange as you get closer to the event horizon, or the end of the black hole before the large pit.
In your eyes, as the one who is falling into the black hole, you would experience time normally. Additionally, once you reach the event horizon, you may survive. To outside observers, you are gone.
