is black hole gravity faster than light

Is the effect of gravity faster than light? What would they sound like, compared to merging black holes? Gravity is so strong that nothing, not even light, can escape. Any light that hits it is still moving at the speed of light, but its path 3. So - Black holes possess a gravitational force so great it can pull anything in. Listen to The Nature Of Technology With Brain Arthur [Idea Machines #41] and forty-three more episodes by Idea Machines, free! Inside the event horizon is where physics goes crazy. Is gravity infinite in a black hole? Home; Forum. What if I travel faster than light? A black hole traps everything including light. 1.2k. The faster it spins, the greater the potential energy gain. A black hole is a region of space that is so warped that not even light can escape. While nothing can go faster than light in vacuum, it is pretty easy for particles to move faster than light in matter through some medium like glass. Assume a photon beam and high energy muon beam point in the same direction and travel at the same speed as light. This is allowed because you never locally exceeded the speed of light. This illustration reveals how the gravity of a black hole warps space and bends the light of a distant star behind it. Granpa is right in his second statement. It is supposedly infinitely small. White Hole Creation - Create white holes that expel anything near them. That is because you would require matter capable of being ejected at speeds faster than lightbut no known particles can travel that fast. Black holes always explode eventually, but that can take trillions of years, so for any practical purpose a black hole is a permanent light trap. One commonly known fact in physics is that you cannot move faster than the speed of light. While that's basically true, it's also an over-simplification. Under the theory of relativity, there are actually three ways that objects can move: Black Hole. I once read about Black Holes in Wikipedia (Unreliable i know) and apparently Time slows down inside them. Infalling matter is shredded by powerful tides and crushed to infinite density. Posted by 9 years ago. Is a black hole faster than light? Insights Author. Gravitational lensing may make it look like it is going faster or slower but speed=d/t will never be more than c. The outer layers emit longer-wavelength light, so making VLBI work with shorter-wavelength light would enable closer-in views approaching the black holes event horizon. 2 Answers. It is named after the physicist Stephen Hawking, who developed a theoretical argument for its existence in 1974. Remember Me? Every photon of light has energy proportional to its frequency. Answer: The short answer is no, the speed of light is unchanged by gravity. identified in 1969 by British astrophysicist Sir Roger Penrose as a mechanism for extracting energy from a spinning black hole. How is time an illusion? Because the phrase "faster than light," in our universe, is exactly equivalent to the phrase "straighter than straight," or "more horizontal than horizontal." No, not as I think of it anyway. Even if you were somehow able to break the laws of physics and travel faster than the speed of light, you still couldn't get out of a black hole. Something must be making out of the black hole - Something that bars everything else from doing so, and that must be gravity. It is not so that because light cannot escape from the gravity of a black hole, gravity must reproduce faster than the light. As a result, black holes are not visible to the eye, although they can be detected from the behavior of light and matter nearby. Gravity is so strong near a black hole that it pulls space inward faster than light can travel away. Close. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole. Stephen Hawking said light will travel faster than c in a black hole but I think he's lost the plot a bit these days, light will travel at c in the vacuum end of story. In this solution, tachyons must travel always faster than the speed of light and have the negative mass squared. 341. Escape speed exceeds the speed of light. It will still be c. You're assuming that the gravitational pull of the black hole prevents light from escaping because the pull is "faster" than the light. Even the black holes affect on the light from stars behind it which causes the light to be bent into an apparent ring around the black hole would be too small for us to see. Inside black holes we could have the right conditions to create dark matter and due to dark matter travelling faster than light can escape the gravity of a black hole, this is known as Hawking radiation. This is energy it has "used" to climb the gravity well. So, at the event horizon the escape velocity becomes the speed of light. The coefficients computed to find a function development (which function depends on polar and azimuthal angle in spherical coordinates) are used in many field of physics. Tour Start here for a quick overview of the site Help Center Detailed answers to any questions you might have Meta Discuss the workings and policies of this site Escape speed exceeds the speed of light. Gravitational Wave Manipulation - Manipulate gravitational waves that ripple space-time. As another example, there are some distant stars in the universe that are moving away from each other at a speed faster than light. The event horizon is where the escape speed exceeds the speed of light: youd have to be going faster than light (which is impossible for any bit of matter) to escape the black holes gravity. It doesn't mean anything. Even if you were somehow able to break the laws of physics and travel faster than the speed of light, you still couldn't get out of a black hole. A black hole is an object whose gravity is so strong that not even light can escape. If light cannot escape a black hole, and nothing can travel faster than light, how does gravity "escape" so as to attract objects beyond the event horizon? Time Travel. Reply #28 on: 20/06/2022 22:59:44 If you want to know why (and how) we actualy use a wrong representation of a black hole (with the wrong mathematic associated) i strongly suggest to view the video made by Jean-Pierre Petit here : There are no tricks around it (that we know of), for example if you fly around with speed v in a spaceship and mount a lamp at the front, the speed of the light will not be v+c. "Hole" because nothing entering can ever escape. a normal Newtonian object with a normal Newtonian gravity field and an escape velocity greater than c could still emit light. In the case of a black hole, it's best to think of gravity as Albert Einstein described it: a warp in space-time. Help; Forgot Password? If a different beam of light was sent from earth to the North Star and did go through the worm hole with you, there is no way you could outrun it. But you can -see- imagine * distances increase quicker than the speed of light. Unless I can go faster than light, a round trip is at least 8 years! The event horizon is where the escape speed exceeds the speed of light: youd have to be going faster than light (which is impossible for any bit of matter) to escape the black holes gravity. A black hole is a region of spacetime in which the attractive force of gravity is so strong that not even light escapes. Now, the escape velocity becomes larger than the speed of light after the event horizon. Remember, the speed of light repels while a black hole attracts, and this creates entropy and compels the arrow of time forward. as the faster the speed of the picture gets, the closer you are to dying. Gravity exerts a force; it doesn't have a speed. Black Hole. Can gravity bend light? So, it's impossible to escape from such a dense object. That's why nothing in our universe can go faster than light. Archived. When you approach either the speed of light or a black hole, time slows, and, in both cases, when you reach either one, time completely stops. I made a video about black holes and gravitational waves. Is a black hole faster-than-light? For relatively lightweight bodies, like Earth, the effect is tiny. There is a point at which light stops because it is traveling outward at the same speed space is pulled inward (called the event horizon). For an object escaping from a Thus, each galaxy is immensely larger than the Earth, and the visible Universe immensely more so. Light actually does the same thing. My reasoning for this is that if light can't escape a black hole but gravity The density of a black hole is extremely high. Can something faster than light escape a black hole? Heres the deal: nothing can travel faster than light. If you toss a rock up in the air, it will only go up a little ways before Tour Start here for a quick overview of the site Help Center Detailed answers to any questions you might have Meta Discuss the workings and policies of this site This means that, for a photon (light) and for black holes, the universe no longer exists! In the SSU (remember this is science fiction) falling into a black hole or going faster than the speed of light means youve gone to the edge of and left the universe. The black hole is the equivalent of dividing by zero. Do gravitational waves travel faster than light? No, gravitational waves also travel at the speed of light in vacuum. However, the interstellar medium is not perfectly empty but filled with plasmas which slow electromagnetic waves (light, radio) down by a factor n, the refractive index. Ultimate Level Everyone wanted to know what would happen if the black holes went faster than the speed of light! However, light has no mass so it is not accelerated by gravitational forces. 2021 Award. Gravity is what keeps us on the Earth, but it can be overcome. The gravity doesn't have to get out of the black hole. if you believe that. This is where black holes come in. Short answer: Nothing happens to time inside a black hole. No one knows exactly what TIME is. One thing we do know is that time is not tangible, and it is not 'moving'. Time just IS - and everything in the universe is moving through time. If you accept this, then you will agree that time cannot 'slow down' or 'speed up'. Because IT IS NOT A BLACK HOLE. And gravity is also an infinitely distant plant, but this is negligible at a certain distance. Never been observed, never will be. Past the event horizon of a black hole, any moving particle instantaneously experiences a gravitational acceleration towards the black hole that will cancel out it's current velocity, even light. Re: Does The Gravity Of A Black Hole Travel Faster Than The Speed Of Light ? So, anything just above the event horizon must move close to the speed of light in order to escape the black holes gravity. Black Hole Creation - Create black holes which suck in matter and energy into oblivion. With that in mind, the idea is that the time distortion allows for the possibility of time travel. The escape velocity for such an object is more than the speed of light and according to Albert Einstein's theory of relativity, nothing can travel faster than the speed of light. Human beings are totally insignificant compared with the size of the Universe. Hawking radiation is thermal radiation that is theorized to be released outside a black hole's event horizon because of relativistic quantum effects. Thus speed of light is zero in blackhole. Inside the event horizon is where physics goes crazy. The steeper the gravitational well, the faster you need to go to escape it, but you need both extreme mass and extreme concentration of that mass before you make it to black hole territory. Under extreme gravity, say near a black hole, that difference in attraction will actually start working against you. So how does gravity escape a black hole? That means that the gravity well of the black hole must be able to accelerate from -C to 0 instantly. Managing Mathematics with Semon Rezchikov [Idea Machines #44]. Why are black holes faster than light? Its a great question, and a perfectly reasonable one given most peoples understanding of gravity. 1. Time and Black Holes and the speed of light. Share Improve this answer edited Jan 3, 2017 at 20:47 Including light. Spherical harmonics are a set of functions used to find a solution of the Schroedinger equation for the hydrogen atom for example, in quantum physics. Scientists have continued to explore the potential connection between black and white holes. Gravity warps time, and a black hole is essentially a massive gravitational body. And outside gravity 'propagates' at 'c', never surpassing it. A black hole is a place where space is falling faster than light. Gravity is so strong that nothing, not even light, can escape. The space within black holes is curved in on itself, and so there is no direction you can travel in to get out of the black hole. You are reporting this thread to the moderators for review and possible removal from the forum. Einstein's theory of special relativity says that mass warps the space around it. The black hole traps light due to its intense gravitational field. Calendar; Community. Does NASA have a zero gravity chamber? The speed of light does not increase or decrease just because it is near a black hole. No signup or install needed. Only until the black hole reaches the inner edge of the asteroid belt would we be able to directly observe the light-bending effects of the black hole. msn back to circling around and heated by a black hole. A jet of material propelled from a disk surrounding the black hole first interacted with the ejecta material to form a broad cocoon. Later, the jet broke through to emerge into interstellar space, where its extremely fast motion became apparent.
