Quiz: What Do You Know About Black Holes?

Black holes are one of the most mysterious natural phenomena in our universe. No one knows exactly how they got here, but scientists have a few ideas. Let’s test your knowledge!How Much Do You Know About Black Holes?

What happens if a person goes through a black hole?

If you leapt heroically into a stellar-mass black hole, your body would be subjected to a process called 'spaghettification' (no, really, it is). The black hole's gravity force would compress you from top to toe, while stretching you at the same time… thus, spaghetti.

How is a black hole formed?

Stellar black holes form when the center of a very massive star collapses in upon itself. This collapse also causes a supernova, or an exploding star, that blasts part of the star into space. Scientists think supermassive black holes formed at the same time as the galaxy they are in.

What are the 4 types of black holes?

There are four types of black holes: stellar, intermediate, supermassive, and miniature. The most commonly known way a black hole forms is by stellar death. As stars reach the ends of their lives, most will inflate, lose mass, and then cool to form white dwarfs.

Is there a white hole?

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.

Do we live in black holes?

5:39 13:01 It can only be crossed from the inside to the outside space flows at the speed of light across theMore

What is the nearest black hole to Earth?

List Distance System (ly) (kpc) Designation 3000±3000.92±0.9A0620-00 (V616 Mon) 5150±5901.58±0.18MOA-2011-BLG-191 or OGLE-2011-BLG-0462 5400+6900 −19001.7±1.4GRS 1124-683 (GU Muscae) 24 more rows

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.

Do wormholes exist?

Wormholes are shortcuts in spacetime, popular with science fiction authors and movie directors. They've never been seen, but according to Einstein's general theory of relativity, they might exist.

Will our Sun become a black hole?

Will the Sun become a black hole? No, it's too small for that! The Sun would need to be about 20 times more massive to end its life as a black hole.

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.

What is a white black 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 we create a black hole?

Scientists have therefore started creating artificial black holes inside labs to study their properties. And one such experiment, carried out by scientists at the Technion- Israel Institute of Technology, has proved that Stephen Hawking had been right about black holes all along.

Is black hole in Milky Way?

The Milky Way's black hole is huge compared to the black holes left behind when massive stars die (opens in new tab). But astronomers think there are supermassive black holes at the center of nearly all galaxies. Compared to most of these, Sagittarius A* is meager and unremarkable.

What is the biggest black hole in the universe?

quasar TON 618 At the other end of the scale there is a true monster: the black hole at the center of the quasar TON 618. It possesses 66 billion solar masses, the most massive yet discovered.

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 did Albert Einstein say about black holes?

Black holes are regions of spacetime where gravity's pull is so strong that nothing, not even light, can escape from being dragged in and "eaten." Einstein's theory of general relativity predicted the existence of black holes and that, no matter what such an object "eats," black holes are characterized only by their

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.

What year will the Universe end?

22 billion years in the future is the earliest possible end of the Universe in the Big Rip scenario, assuming a model of dark energy with w = −1.5. False vacuum decay may occur in 20 to 30 billion years if the Higgs field is metastable.

Is Earth in a black hole?

Read our answers to some of the big questions about black holes. Despite their abundance, there is no reason to panic: black holes will not devour Earth nor the Universe. It is incredibly unlikely that Earth would ever fall into a black hole.
