Is there anything at the center of a black hole?
The singularity at the center of a black hole is the ultimate no man's land: a place where matter is compressed down to an infinitely tiny point, and all conceptions of time and space completely break down. And it doesn't really exist.Is there anything behind a black hole?
"Any light that goes into that black hole doesn't come out, so we shouldn't be able to see anything that's behind the black hole," said lead author Dan Wilkins in a statement. "The reason we can see that is because that black hole is warping space, bending light and twisting magnetic fields around itself."Is there space inside a black hole?
Don't let the name fool you: a black hole is anything but empty space. Rather, it is a great amount of matter packed into a very small area - think of a star ten times more massive than the Sun squeezed into a sphere approximately the diameter of New York City.What elements are at the center of a black hole?
Most notably, every black hole has at its effective center, a singularity, which consists of matter so compressed that it is almost a point mass.Does time stop in a black hole?
Time does stop at the event horizon of a black hole, but only as seen by someone outside the black hole. This is because any physical signal will get infinitely redshifted at the event horizon, thus never reaching the outside observer. Someone falling into a black hole, however, would not see time stop.Travel INSIDE a Black Hole
Can a wormhole exist?
In the early days of research on black holes, before they even had that name, physicists did not yet know if these bizarre objects existed in the real world.What would Spaghettification feel like?
Because of the tidal forces it would feel as if you are being stretched head to toe, while your sides would feel like they are being pushed inward. Eventually the tidal forces would become so strong that they would rip you apart. This effect of tidal stretching is sometimes boringly referred to as spaghettification.What is beyond a black hole?
At the center of a black hole the gravity is so strong that, according to general relativity, space-time becomes so extremely curved that ultimately the curvature becomes infinite. This results in space-time having a jagged edge, beyond which physics no longer exists -- the singularity.Do white holes exist?
White holes cannot exist, since they violate the second law of thermodynamics. General Relativity is time symmetric. It does not know about the second law of thermodynamics, and it does not know about which way cause and effect go.Can you destroy a black hole?
Black holes are among the most destructive objects in the universe. Anything that gets too close to a black hole, be it an asteroid, planet, or star, risks being torn apart by its extreme gravitational field. By some accounts, the universe may eventually consist entirely of black holes.Is time Travelling possible?
Yes, time travel is indeed a real thing. But it's not quite what you've probably seen in the movies. Under certain conditions, it is possible to experience time passing at a different rate than 1 second per second. And there are important reasons why we need to understand this real-world form of time travel.What is inside a white hole?
White holes are theoretical cosmic regions that function in the opposite way to black holes. Just as nothing can escape a black hole, nothing can enter a white hole. White holes were long thought to be a figment of general relativity born from the same equations as their collapsed star brethren, black holes.Can Earth be swallowed by a black hole?
Will Earth be swallowed by a black hole? Absolutely not. While a black hole does have an immense gravitational field, they are only “dangerous” if you get very close to them.What are wormholes made of?
Physicists believe wormholes may have formed in the early universe from a foam of quantum particles popping in and out of existence. Some of these “primordial wormholes” may still be around today.Does black hole bend time?
In short, black holes are massive pits of gravity that bend space-time because of their incredibly dense centers, or singularities.. When a star dies, it collapses inward rapidly. As it collapses, the star explodes into a supernova—a catastrophic expulsion of its outer material.How many universes are there?
In a new study, Stanford physicists Andrei Linde and Vitaly Vanchurin have calculated the number of all possible universes, coming up with an answer of 10^10^16.Are there black holes in the ocean?
Black holes don't only exist in the cold distance of deep space, they also exist right here on Earth, swirling in the oceans.Can a human survive spaghettification?
Your body would follow geodesics, and hence the whole structure of your body will continue to exist as it did before, simply living in a space with different rules. Of course, given that nothing else but space curvature interferes with you (e.g. radiation from black hole).Would you feel pain in a black hole?
The fate of anyone falling into a black hole would be a painful “spaghettification,” an idea popularized by Stephen Hawking in his book “A Brief History of Time.” In spaghettification, the intense gravity of the black hole would pull you apart, separating your bones, muscles, sinews and even molecules.Can a black hole eat a galaxy?
A single Black Hole, even one at the center of our Milky Way galaxy, is just too small to eat an entire galaxy.Can time be bent?
So to answer your question, time does not literally "bend". A massive object modifies the proper time interval around it such that an outside observer would see objects near the mass experience less time and spacetime intervals would have their spatial components modified accordingly.What creates a white hole?
White holes are created when astrophysicists mathematically explore the environment around black holes, but pretend there's no mass within the event horizon. What happens when you have a black hole singularity with no mass? White holes are completely theoretical mathematical concepts.What did Einstein say about wormholes?
Einstein's theory of general relativity mathematically predicts the existence of wormholes, but none have been discovered to date. A negative mass wormhole might be spotted by the way its gravity affects light that passes by.What would happen if two black holes collide?
It is possible for two black holes to collide. Once they come so close that they cannot escape each other's gravity, they will merge to become one bigger black hole. Such an event would be extremely violent. Even when simulating this event on powerful computers, we cannot fully understand it.
