Could we be living in a black hole?

We might live in a universe within a black hole within a universe within a black hole. It might just be black holes all the way down.

Could life exist inside a black hole?

So planets could potentially form around black holes, but that's no guarantee that they offer a life-friendly environment. On Earth, living things are hugely dependent on the light and warmth from the Sun to survive. Without the glow of a star, life around a black hole would likely need an alternative source of energy.

What if we lived in a black hole?

Of course, no matter what type of black hole you fall into, you're ultimately going to get torn apart by the extreme gravity. No material, especially fleshy human bodies, could survive intact. So once you pass beyond the edge of the event horizon, you're done. There's no getting out.

Is Earth in danger of a black hole?

Since this black hole already weighs a few million times the mass of the Sun, there will only be small increases in its mass if it swallows a few more Sun-like stars. “There is no danger of the Earth (located 26,000 light years away from the Milky Way's black hole) being pulled in.

Is there a white hole?

The short answer, unfortunately, is no. White holes are really just something scientists have imagined — they could exist, but we've never seen one, or even seen clues that one may exist. For now, they are an idea. To put it simply, you can imagine a white hole as being a black hole in reverse.

Could The Universe Be Inside A Black Hole?

Are we rotating around a black hole?

Yes. All astronomical objects, including black holes, are formed by gravity pulling matter together. If a cosmic body originates from anything that had even the tiniest amount of rotational motion originally, then this spin rate will become greatly enhanced as the object collapses.

What's at the bottom of a black hole?

According to our best theory of gravity, Einstein's theory of general relativity, your spaghettified body would eventually end up at a 'singularity' – an infinitely small and dense point at the 'bottom' of the black hole.

Can a wormhole exist?

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.

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.

Can a human survive a wormhole?

Humans could survive a trip through a wormhole, but there's a catch. There are drawbacks to this method — namely, such wormholes would be only microscopic, which means even the most hardcore exercise routine wouldn't make humans thin enough for the trip.

Can humans create wormholes?

To create a wormhole on Earth, we'd first need a black hole. This is problematic: creating a black hole just a centimetre across would require crushing a mass roughly equal to that of the Earth down to this tiny size. Plus, in the 1960s theorists showed that wormholes would be incredibly unstable.

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.

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.

What is the biggest black hole in the universe?

Ton 618, the largest ultramassive black hole, appears at the very end of the video, which, at 66 billion times the mass of the Sun, is going to weigh very heavily on how we daydream about the cosmos moving forward.

Is black hole faster than light?

Using NASA's Chandra X-ray Observatory, astronomers have seen that the famous giant black hole in Messier 87 is propelling particles at speeds greater than 99% of the speed of light.

What is the fastest thing in the universe?

The fastest thing in the universe is the speed of light in vacuum. Nothing travels faster than the speed of light which is equal to 3 x 10⁸ m/s.

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.

What is on the other side of a black hole?

The discovery of light from the other side of a black hole was predicted by Einstein's theory of general relativity. But it has never actually happened before, and the discovery marks the first time that light has ever been directly observed coming from behind a black hole.

What happens if a black hole and a white hole collide?

For reference, that's 3 million times larger than Earth. So if a white hole and black hole collided, we'd have a massive black hole roaming around the Universe, destroying everything in its path.

Will the 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.

How long is one minute in a black hole?

Black hole news: Standing on edge of black hole would cause 700 years to pass in 1 minute.

How many dimensions do we know of?

The world as we know it has three dimensions of space—length, width and depth—and one dimension of time. But there's the mind-bending possibility that many more dimensions exist out there. According to string theory, one of the leading physics model of the last half century, the universe operates with 10 dimensions.

What would happen if a black hole the size of a coin?

If a penny-sized black hole did form on Earth, the planet would indeed be destroyed killing everyone on it, but the process would likely be different than in the video above. A penny-sized black hole would have roughly the same mass as the Earth for reasons explained later.
