Do black holes exist as seen from any point of reference?

Question

If we were traveling at a very high speed, is it possible that what seems to a "slow" observer to be a black hole, is not a black hole for us traveling way faster?

If we were sucked by a black hole, wouldn't our speed vastly? If it did, then couldn't we accelerate to a speed where that black hole is no longer a black hole?

Just wondering :)

Answer 1

Black holes do seem to exist from every point of reference. If you went beyond the event horizon, time would slow down and eventually stop. An outside observer would see you get closer but never get there because of time dilation.

Answer 2

OK. First things first.
A black hole is a star with a gravitational force much bigger than it should have. Or the mass of a celestial being compressed to a very small size so the previous rule works.

A person traveling in space at a very high speed would not seem like a black hole to an observer, but merely an object traveling at a very high speed.

And if the person or object were to be sucked by a black hole, they most likely would be crushed to smaller than atoms. Therefore, you can't accelerate. And you can never make a black hole turn into something else. That's the highest position an object could gain. A black hole is a black hole and that's that. You can't make a black hole 'stop' being a black hole.

I hope this helps you with your question. You can always research for more concise answers and explanations. Once you understand the rules for black holes, you can understand what we know about black holes.

Answer 3

Black holes do exist as black holes, even for observers travelling at high speed. Even observers travelling very near the speed of light will be captured by a black hole, since even light is captured by a black hole.

The "surface" of a black hole doesn't look like anything---it is empty space, and looks like empty space to someone near it. It is more of an imaginary "point of no return": if you pass it, not even light can get out. Once you pass the event horizon, you must move toward the center---but this is more like moving forward in time than moving fast in space.

Answer 4

An object (Space craft, etc.) travelling through space will tend to travel on a tangent, (A straight line.) If it enters the sphere of influence of a black hole it will change course toward the black hole and will increase its velocity exponentially as it approaches the black hole. This velocity will become sufficient that the craft will instead of going into orbit around the black hole warp its course and head off in a different direction. It will be moving too rapidly to be sucked into the black hole.

Answer 5

Yes. In the 1979 movie "The Black Hole," the crew of the Palomino spaceship passes through a black hole and enters a world of confusion where space and time are warped.

But in reality, if the crew approached the surface of a compact object, which Einstein's theory of general relativity would identify as a black hole, they would all disintegrate, according to Lawrence Livermore National Laboratory physicist George Chaplin.

Chaplin says that ordinary matter would break apart because the protons and neutrons in the matter would disintegrate. Further, Chaplin says black holes do not really exist. Instead, he proposes that the mass of compact astrophysical objects consists of the same dark energy that makes up 60 percent of the mass of the universe.

According to general relativity, a black hole results from the death of a massive star and its eventual collapse under its own gravity to a single point; space and time switch places inside a boundary called an "event horizon." Quantum mechanics, however, dictates that space and time continue to play their usual roles inside compact objects, causing a whole barrage of strange behavior – behavior that Chaplin says occurs in a dark energy star as well as on Earth when studying quantum critical phenomena. In such phenomena, small changes in the external conditions of a material can cause dramatic and anomalous subatomic changes, called quantum phase transitions, in the material's properties.

"There has never been direct evidence of a black hole," said Chapline, while acknowledging there are objects that general relativity would predict are black holes at the centers of galaxies. "Ironically, Einstein also didn't believe in black holes even though he created general relativity.

"Quantum critical phase transitions are not just possible but have actually been seen in the Laboratory," he said.

High temperature superconductivity is an example of quantum critical behavior. Chapline said that plutonium may be another example of an earthly quantum critical system; indeed it is the only example of a pure element that displays quantum critical behavior.

Just how general relativity and quantum mechanics are incompatible has intrigued Chapline for more than 20 years. But it wasn't until the summer of 2000 when Chapline was working on an assignment at Los Alamos National Laboratory that he ran into Nobel laureate and former Livermore physicist Robert Laughlin and the two discussed how a quantum phase transition could represent a surface where time stands still.

Chapline and Laughlin pointed out how the behavior of space-time in dark energy stars is very similar to how a superfluid confined to a vertical column might behave. The pressure in the superfluid increases with depth, and if at a certain depth, the speed of sound vanishes – sound is trapped in the fluid – then the physical behavior would be indistinguishable from the event horizon of a classical black hole, Chapline said.

"The key is that when the speed of sound goes to zero it's a signature of quantum criticality," he said. "When sound waves cross this surface, there are very dramatic physics effects."

In a dark energy star, however, Chapline said elementary particles, such as photons, electrons, or quarks, crossing over the quantum critical surface – which replaces the event horizon in a classical black hole – will morph into particles with a large mass and become unstable. Inside the dark energy star, space-time is just like normal space-time except that the vacuum energy inside is much larger than the cosmological vacuum energy outside the star.

And though his theory has string theorists and general relativists scratching their heads, Chapline sees a future that might just offer an alternate explanation of what happened during the Big Bang.

"This does go against the mainstream predictions of general relativists," he said. "When I came up with this idea, people just thought I was crazy for many, many years. But in 10 years, this will be the orthodox belief. This explanation of dark energy stars will help explain dark matter. This could profoundly change our whole view of the universe."

Answer 6

We note black holes by observing mass and energy being "sucked" into them. They do not seem to be moving unusually fast. As for relativistic travelers, they probably could "see" somthing like the accretion of mass and energy which would tip them off that they were in a black hole region. However, the process is a very gradual one, like the coin-collecting charity gadget you see sometimes at malls where the coin spirals around the "black-hole"-like shape faster and faster until it -poofs.

Answer 7

ok, enable's no longer confuse theoretical mathematical fashions with certainty. there's a static answer to the Einstein container equations that has a gravitational singularity interior the middle, and vacuum everywhere else. it is commonly stated as the "black hollow" answer. yet, can any affiliation of count easily get into that configuration? the respond is: no, and for the justifications you describe on your question. Does this make any distinction? the respond is returned: no (greater often than not), as a results of fact a collapsing huge call, outdoors the form horizon, behaves so further to a theoretical black hollow that the clever ameliorations are negligable. Admittedly, there are consistently some tiny ameliorations between the gravitational container of a collapsing huge call and a theoretical black hollow, yet those ameliorations decay on the instant (in a count of a few mild crossing circumstances of the form horizon, it relatively is to declare some seconds). A collapsing huge call, after an particularly couple of minutes, looks and behaves precisely like a theoretical black hollow. it is genuine regardless of in case you enter the black hollow to learn it out interior, and get caught to the singularity. So the theoretical answer for a black hollow is easily fairly clever for calculating fairly much something it relatively is particularly useful to comprehend a few collapsing huge call.

Answer 8

First off black holes can not be seen. They do exist and can be sensed from any direction. A black hole is always a black hole.

Answer 9

We really don't know what's inside the black hole or what lies beyond the event horizon, so we can't really tell.

Excuse me, what is the speed of a person sucked by a black hole?
