Can you survive a black hole?

Regardless of the explanation, we do know that it is highly unlikely that anyone entering a black hole would survive. Nothing escapes a black hole. Any trip into a black hole would be one way. The gravity is too strong and you could not go back in space and time to return home.

Can you travel through a black hole?

Thorne told Space.com that journeys through these theoretical tunnels would most likely remain science fiction, and there is certainly no firm evidence that a black hole could allow for such a passage. But, the problem is that we can't get up close to see for ourselves.

What would happen if a human went 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.

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.

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.

How to Survive a Black Hole

Are wormholes real?

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.

Can you 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.

Is our universe in a black hole?

The birth of our universe may have come from a black hole. Most experts agree that the universe started as an infinitely hot and dense point called a singularity.

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.

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'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.

Will humans ever create a wormhole?

A wormhole is effectively just a tunnel that connects two places in the Universe. So far scientists have simulated this process, but are nowhere near creating a gravitational wormhole, as it would require us to create huge amounts of gravitational energy - something we don't yet know how to do.

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.

Has anyone been in a Blackhole?

It is absolutely not possible to go into a black hole and come out again. In a way this is the real definition of a black hole. Not even light can escape, and light moves very very fast!

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.

Does gravity bend time?

The gravitational field is really a curving of space and time. The stronger the gravity, the more spacetime curves, and the slower time itself proceeds.

Why can't we take a picture of a black hole?

Sasada: “To take the picture we use radio techniques only looking at small-scale emissions, because of an extremely sparse baseline coverage (very sparse locations of telescopes on the Earth). The Event Horizon Telescope cannot detect medium or large-scale light emissions around the black hole.

Does the past still exist?

In short, space-time would contain the entire history of reality, with each past, present or future event occupying a clearly determined place in it, from the very beginning and for ever. The past would therefore still exist, just as the future already exists, but somewhere other than where we are now present.

Is time an illusion?

According to theoretical physicist Carlo Rovelli, time is an illusion: our naive perception of its flow doesn't correspond to physical reality. Indeed, as Rovelli argues in The Order of Time, much more is illusory, including Isaac Newton's picture of a universally ticking clock.

Is warp speed possible?

“None of the physically conceivable warp drives can accelerate to speeds faster than light,” Bobrick says. That is because you would require matter capable of being ejected at speeds faster than light—but no known particles can travel that fast.

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.

Did we create a black hole?

To study the phenomenon more closely, physicists in Israel managed to create a lab-grown, analogue black hole using some thousand atoms. This faux black hole exhibited all properties of a black hole in the state in which it is believed to exist in space.

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.
