I think this video is wrong, i believe it would take earth 8 minutes to feel the effects of the missing sun. The effects of gravity on spacetime ripples at the speed of light.
@caelanbains that would be about it...if the disappearence does not kill us ( i wouldn't know how it could miss us) the absence of light and heat, changes in gravity would kill us for sure.
@returnofthekingxd Not always. The Sun will only become a Black Hole if it's mass is above a certain value (Called 'X' for explanatory Purposes). If the Suns Mass is greater than X, it will collapse under it's own gravitational field, and become an object with Zero Mass and Infinite Density AKA A Black Hole. If it's mass is below X, it will burn out, and leave it's core behind, becoming a Neutron Star AKA A white Dwarf.
Why are we debating the outcome of an impossible scenario? Matter cannot suddenly disappear. We shouldn't worry ourselves much with things that are completely imperceptible, such as this.
You are contradicting yourself. You are first claiming that gravity propagates at infinite speed (Earth immediately changes direction relative to distant stars), then you show an animation of the effects of (no) gravity propagating at a finite speed.
Which is it? You can't have it both ways.
The question is not settled. Many accept the results of an experiment done by Professor Sergei Kopeikin in 1992 (which supports general relativity), but others question his interpretation of the results.
@Drumwannabe17 It's more about asking a question that would make a person think about how gravity works. We know the sun can't disappear but if it did then how would gravity react? Would the Earth instantly fly off it's orbit? If it does not the what would be the delay time and why? It's a classic thought experiment.
@Nufrifin If the sun suddenly ceased to exist, that bend in spacetime would flatten out and there would be no more bend in the sheet, thus the earth and all planets orbiting the sun would fly off into space in a direction tangent to the point in the circle (earth's orbit) where it was when the bend in spacetime flattened out. Sorry if that's still confusing, it sounded much simpler in my head.
@Drumwannabe17 Eh, one might otherwise be inclined to perceive that the warped spacetime (gravity) wouldn't instantly unwarp itself if the sun were to suddenly vanish. It would continue to exert the gravitational force shortly, even in its absence, because of relativity. Just because the sun suddenly stopped existing doesn't mean that the Earth's own gravitational pull would suddenly stop, since from the Earth's position, the sun still exists!
@Acosmicist While I understand where you're coming from, the fact remains that gravity can no more instanaeously disappear than a photon can after you make a light bulb disappear.
gravity doesnt have the speed of light because it not yet proven it there are any gravitrons which somehow work in a way we dont know yet. because even if we are thousands of thousands of lightyears away, our sun still affects another sun on the other end of the universe and pulls it towards him.
If an object such as the sun were to hypothetically instantly disappear, the distortion in space time that holds the planets in their orbits, known to use as gravity, would likewise instantly cease to exist. However, I would think there would be a "twang" of spacetime - which you represented as a flat gravity wave traveling at the speed of light. Would that "twang" reveberate from negative to positive indentation of spacetime? Resonating like a drum so that planets disperse with a zig-zag path?
@ohwhererehwho I was just considering this. If space-time behaves like a wave, then wouldn't there be oscillation? And does this imply some sort of elasticity constant like property? And since you say that this would be a temporary "twang" this also implies dampening, which asks the question, what medium is our universe in?
so information goes faster than light? Bollocks. Earth can't "know" the sun has disappeared so how can it already be flying straight all of the sudden? Do your homework before making an instructional video (this one is destructional).
@roemelvs Massive objects like the sun also don't cease to exist... it is for this reason that you are encountering this anomality. I believe the science is correct given the impossible axiom that an object ceases to exist you will no doubt encounter events that are abnormal such as the one you re describing
@roemelvs Um, have you ever heard of entanglement? No matter, I think the fundamental assumption you are making is that there is no contact between matter except for in space-time. I do not find it absurd to say that gravity holds onto an object the way your hand can hold onto a ball. And just as you let go, any remaining forces take hold immediately. I find it strange to say that it takes time at the speed of light for the ball to realize it is no longer being held.
The earth will stay in orbit until the sun's light vanishes. Nothing can travel faster than light (except nutrinos - under investigation). The earth will not instantly leave orbit. If the sun's light is reaching the earth the sun IS there and so is the gravitation. In short this is wrong! How can the gravity bend the star's light, but not affect the earth?
@Rastermon I'm not so sure that isn't a misconception. Einstein's equations limit the speed of energy and matter to the speed of energy in the form of light traveling in a vacuum. We've never been able to measure the speed of force, though, and gravity is a force, not energy. The truth is, we don't know what would happen if the sun suddenly disappeared. If gravity waves exist, it would be proof that change in force can't exceed the speed of light, but they've never actually been detected.
To all ppl starting to talk about the laws of physics. They only work here, on our planet. In space there are other laws. If you don't believe me, I don't give a shit. But that's why you can't explain 99% of life.
@Lecluyse2000 noooo, the sun will never sudden disappear like suggested in the video. Even the idiot who made the video understood that part, it's just a thought experiment.
einstien sed that the light speed was the speed limit in the universe, witch is 299 792 458 m / s, so the gravity cant be instantly felt if the sun disapers, the earth whould continue to rotate around the sun for about 8 minutes, the time that light takes to reach the earth. in that video, we see that the earth loses his atraction to the sun immediately after the sun disapear. (sorry for the bad righting, im french)
@lightspeedproject It's also been widely stated by current scientists that Einstien was wrong on many counts of his theory of relativity. Also riddle me this, gravity can be the single most powerfull force in the universe. If it could not overcome light, then why would there be black holes, a point of infinity dencity and zero volume. If light could overcome said force, it would not, as it were be drawn into it. Or warped by the gravity of stars.
Correct me if I'm wrong here, but don't gravitational waves travel at the speed of light in a vacuum?
Thus, it would take 8 minutes for the Earth to be affected and in the animation the Earth should stay on its orbit until the flat cylinder spreading outwards from the Sun's location reaches Earth. Only then should it leave its orbit.
@TOIJALANABC Besides, if gravitational waves traveled faster than the speed of light, the people at SETI would be complete idiots to search for extra-terrestial messages in radio signals. Not that it makes much sense as things are either, but still, if the effect of gravity was instantaneous, radio signals would obviously not be the means of inter-planetary communication in the galaxy.
@stevey226 No, and I also wouldn't want to wait for a year every time the ball goes around the well.
The point is that the planet shouldn't be affected before the flat area in the middle of the gravity well has spread out as far as the planet's orbital radius.
Let's put it this way... Imagine that you're constantly sending rocks rolling down a hill in the dark and it takes them 8 minutes to get down. If you stopped sending them, there'd still be rocks arriving down for another 8 minutes.
@TOIJALANABC My point was the majority of people watching this video probably already know that so waiting for 8 minutes in this video would be pointless. Showing the effects straight away is more logical.
No it is not more logical because it is just plain wrong. My point wasn't that the video should be over 8 minutes long. It doesn't make any difference what the selected time scale is.
My point was that the planet shouldn't exit its orbit before the effect of the new gravity reaches it. The fact that the planet in this video takes off before the ray of light is affected is incorrect and not in accordance with the Laws of Physics. At this time scale the planet heads off about 20 seconds too early
@stevey226 You wouldn't know it had happened until 8 minutes later.. how could you possibly measure that? well, quantum entanglement in theory, but how else? xp
@TOIJALANABC gravity doesn't 'travel' at all. there is nothing moving so the speed limit of light doesn't come into play. for any practical or even theoretical purposes it is ingrained into space-time itself....i think.
@jesuslovespee Gravity is information and according to our current understanding information cannot be conveyed faster than at the speed of light in a vacuum.
If gravity could convey information instantaneously, there would really be no point for the SETI program to be listening to radio waves. Gravity would be the obvious choice for interstellar communication for any advanced civilization.
@SoulOfMasterDragon Gravity is a (rank 2 tensor) field, much like electromagnetism is (rank 1 tensor) vector field. Gravitational wave is a field solution to the Einstein equation for moving masses.
I think not only it takes 8 minutes for the effect to come to the Earth. When it come to the Earth, it will be accompanied by a crazily fluctuating gravity owning to the rapid chance of mass density at the position of the sun. Resulting in tidal forces that destroy all matters.
@TOIJALANABC Gravity is not tied to electromagnatism yet (no accepted unified field theory), so we can't say that it goes at the speed of light (c = 1/sqrt(e0u0) so it is entirely based on electromagnetism).
@TOIJALANABC I got to thinking about it, and a similar question would be, "what if a magnet exceeded the speed of light?" Would the field just drag behind the magnet? Would it cease to exist?
This doesn't make sense. The same gravity wave mentioned here has to reach the Earth before it can fly off. After all, there's still a curve at that point before the wave arrives, so why should the Earth fly off? So the gravity at Earth doesn't stop at the same time the sun vanishes, rather, it stops at the same time the darkness arrives.
This video uses Newtonian gravity where gravity is instantanous. At least we were to go on how you made the earth break of its orbit before the gravitational wave reached it.
Nothing can move faster than light, including gravity. The earth would go off in a tangental line at the same time that the light from the sun stopped reaching the earth, about 8 minutes. For those 8 minutes, the earth would continue spinning around the nonexistant sun.
@TheSeventhCamera So far nobody has ever seen anything that can, so it looks to be a fairly good law. Also, relativity says that if something could go faster than light, then it must be able to go back in time. Going back in time seems fraught with logical paradoxes, thus believed impossible (and hence, so too would be going faster than light.).
@mike4ty4 I guess since this law applies to the universe, we may never find anything that goes faster than light, but until we find everything in the universe there could always be something that can. But why if something can go faster than light, why would it be able to go back in time? I used to believe the theory that slowing down time could be possible because nothing can go faster than light, but then I realized that we aren't sure that nothing can go faster than light.
This video is wrong. The planets will continue to move around the gravitational well of the Sun and will only fly off when the gravitational wave reaches their orbit. The curvature of space due to the mass of the Sun means all the planets, though moving in a circle, are actually moving in a relative straight line the same way us standing on the ground equates to us accelerating "upward", felt as pressure between you feet and the ground. An apple falling would be relatively motionless.
this is wrong the planets wod stay in their orbits until the gravitation form the sun vanished: the gravitation wave is shown in the video.... i think....
there should be warnings before you click on crappy videos like this. I want my 1:35 back, and the time it took me to write this reply, but I guess this time waste is my own fault. Why narrate it that way, and what frickin physics did you learn son? go back to the sandbox chump!
Gravity is demonstrably much faster than light. Ask any astronomer if he includes light travel time delay when working a problem in celestial mechanics (orbits of the planets). Look up Roemer and the light-time effect of the Galilean satellites. And before you go spouting Newton and Einstein without understanding either, head over to the MetaResearch site and look up the material this animation was created to illustrate.
@metryq Light travel time delay results in only a very small correction for planetary orbits and can be generally ignored. Note that with special relativity, if there is ANY mechanism for sending information faster than light, then it becomes possible to send information back in time (this is because moving observers disagree about what events are simultaneous). This means that we must either discard causality, or faster-than-light information transfer (including FTL gravitational effects).
@metryq Nothing is faster than light. Einstein proved this almost a century ago. Pull your head out of Newton's ass and accept that Newton got gravity wrong. Don't get me wrong, he was a genius, he invented calculus and his laws of motion are perfect, but he got gravity wrong.
this isn't right, the earth would keep revolving for about 8 minutes (the time it takes light to get from sun to earth) considering gravity moves as fast as light.... Enstine proved this many many years ago... get it right newblet >>"
The earth does not almost immediately veer off course. That's the Newtonian (I believe Newton proposed this) way of thinking was proven false by Einstein. As we all know, Einstein stated that nothing can travel faster than light, which includes gravity. If the sun were to suddenly disappear, it would take 8 minutes for the earth to veer off course. Of course it would SEEM instantaneous since the light from the sun would also disappear in 8 minutes
Secondly, why would the effects of gravity effect the planets instantly but take longer to unbend light? It's the same effect, it either does one or the other, it can't do both.
Like if you had a sink full of water with a cyclone of water going down the drain. If you were to suddenly plug the drain the water would not suddenly stop spinning. This video is very inaccurate.
the earth will continue to orbit the sun unchanged for 8 minutes. At that point everything goes dark and the gravity wave spanks us outward into an giant spiral.
This animation doesn't make any sense. When the sun disappears why does the earth 'immediately' continue in a tangent projection even though the gravity well apparently continues to exist....?
@JinKang0122 Yeah, I heard that too! Think it was in The Elegant Universe or some other doc.
If the Earth did lost orbit immediately (as stated here) then the speed of the effect of the suns disappearance on Earth would be faster than light. Einstein would not be best pleased about that!
When the sun vanishes, the peeps form an underground society that lives off the geothermal energy. 100 million years from now a new species of human will evolve. They will have gigantic eyes and thick, furry coats. When the errant earth crashes into another star, all life will be extinguished except the acids containing DNA to start the life cycle process again after supernova.
the earth would take 7 minutes to leave it's orbit, the same time the last photon from the sun would take to reach us. That is precisely what Einstein implied with the "cosmic speed limit", being the speed of light. THE VIDEO IS WRONG, PEOPLE!!
"What happens if the Sun suddenly ceases to exist?"
Space implodes as it fills the void left behind. As all this mass (mostly hydrogen) collides in the center, the impact is so great, and fast, that nuclear fusion happens and a new star is born, just like that.
In the mean time, Earth has become a new moon of Jupiter.
Hmmm ... ResediVlad's comment makes me think about something. What will occur first? The loss ov gravitational pull or the loss of sunlight? Btw, I think sun light spends about 8 minutes getting here O.o
For everyone that thinks gravity can not exceed the speed of light are wrong.
Einstein' theory of relativity implies that the gravitational speed is equal to the speed of light thus it would have a near immediate effect on Earth
Unless I'm missing something here, this video claims that the information about the Sun's sudden existential crisis travels from Sun to Earth (and other orbiting bodies) instantly or almost instantly, independent of the gravity shock wave.
This is false. Local space-time geometry (gravity) remains unchanged for the orbiting bodies until the gravitational shockwave reaches them. This depends on the propagation velocity of gravitational waves which is hard to measure and hence unknown for now.

The fact that the planet in this video takes off before the ray of light is affected is incorrect and not in accordance with the Laws of Physics. At this time scale the planet heads off about 20 seconds too early

@TOIJALANABC gravity doesn't 'travel' at all. there is nothing moving so the speed limit of light doesn't come into play. for any practical or even theoretical purposes it is ingrained into space-time itself....i think.

@jesuslovespee Gravity is information and according to our current understanding information cannot be conveyed faster than at the speed of light in a vacuum.
If gravity could convey information instantaneously, there would really be no point for the SETI program to be listening to radio waves. Gravity would be the obvious choice for interstellar communication for any advanced civilization.

@TOIJALANABC Gravity is not a wave. Read a bit more... Scientists cannot tell what gravity is, whether it be a force, an energy, or whatever.

@SoulOfMasterDragon Gravity is a (rank 2 tensor) field, much like electromagnetism is (rank 1 tensor) vector field. Gravitational wave is a field solution to the Einstein equation for moving masses.
I think not only it takes 8 minutes for the effect to come to the Earth. When it come to the Earth, it will be accompanied by a crazily fluctuating gravity owning to the rapid chance of mass density at the position of the sun. Resulting in tidal forces that destroy all matters.
bbsonjohn 2 months ago
@TOIJALANABC Gravity is not tied to electromagnatism yet (no accepted unified field theory), so we can't say that it goes at the speed of light (c = 1/sqrt(e0u0) so it is entirely based on electromagnetism).

@TOIJALANABC I got to thinking about it, and a similar question would be, "what if a magnet exceeded the speed of light?" Would the field just drag behind the magnet? Would it cease to exist?

This doesn't make sense. The same gravity wave mentioned here has to reach the Earth before it can fly off. After all, there's still a curve at that point before the wave arrives, so why should the Earth fly off? So the gravity at Earth doesn't stop at the same time the sun vanishes, rather, it stops at the same time the darkness arrives.

Nothing can move faster than light, including gravity. The earth would go off in a tangental line at the same time that the light from the sun stopped reaching the earth, about 8 minutes. For those 8 minutes, the earth would continue spinning around the nonexistant sun.

TheSeventhCamera 10 months ago
@TheSeventhCamera So far nobody has ever seen anything that can, so it looks to be a fairly good law. Also, relativity says that if something could go faster than light, then it must be able to go back in time. Going back in time seems fraught with logical paradoxes, thus believed impossible (and hence, so too would be going faster than light.).
mike4ty4 9 months ago
@mike4ty4 I guess since this law applies to the universe, we may never find anything that goes faster than light, but until we find everything in the universe there could always be something that can. But why if something can go faster than light, why would it be able to go back in time? I used to believe the theory that slowing down time could be possible because nothing can go faster than light, but then I realized that we aren't sure that nothing can go faster than light.
TheSeventhCamera 9 months ago
This video is wrong. The planets will continue to move around the gravitational well of the Sun and will only fly off when the gravitational wave reaches their orbit. The curvature of space due to the mass of the Sun means all the planets, though moving in a circle, are actually moving in a relative straight line the same way us standing on the ground equates to us accelerating "upward", felt as pressure between you feet and the ground. An apple falling would be relatively motionless.

Gravity is demonstrably much faster than light. Ask any astronomer if he includes light travel time delay when working a problem in celestial mechanics (orbits of the planets). Look up Roemer and the light-time effect of the Galilean satellites. And before you go spouting Newton and Einstein without understanding either, head over to the MetaResearch site and look up the material this animation was created to illustrate.
metryq 11 months ago
@metryq Light travel time delay results in only a very small correction for planetary orbits and can be generally ignored. Note that with special relativity, if there is ANY mechanism for sending information faster than light, then it becomes possible to send information back in time (this is because moving observers disagree about what events are simultaneous). This means that we must either discard causality, or faster-than-light information transfer (including FTL gravitational effects).
bdonlan 11 months ago
@metryq Nothing is faster than light. Einstein proved this almost a century ago. Pull your head out of Newton's ass and accept that Newton got gravity wrong. Don't get me wrong, he was a genius, he invented calculus and his laws of motion are perfect, but he got gravity wrong.

The earth does not almost immediately veer off course. That's the Newtonian (I believe Newton proposed this) way of thinking was proven false by Einstein. As we all know, Einstein stated that nothing can travel faster than light, which includes gravity. If the sun were to suddenly disappear, it would take 8 minutes for the earth to veer off course. Of course it would SEEM instantaneous since the light from the sun would also disappear in 8 minutes
ChronicallyConfused 11 months ago
First off, the narration is terrible.
Secondly, why would the effects of gravity effect the planets instantly but take longer to unbend light? It's the same effect, it either does one or the other, it can't do both.
Like if you had a sink full of water with a cyclone of water going down the drain. If you were to suddenly plug the drain the water would not suddenly stop spinning. This video is very inaccurate.

If the Earth did lost orbit immediately (as stated here) then the speed of the effect of the suns disappearance on Earth would be faster than light. Einstein would not be best pleased about that!

When the sun vanishes, the peeps form an underground society that lives off the geothermal energy. 100 million years from now a new species of human will evolve. They will have gigantic eyes and thick, furry coats. When the errant earth crashes into another star, all life will be extinguished except the acids containing DNA to start the life cycle process again after supernova.

the earth would take 7 minutes to leave it's orbit, the same time the last photon from the sun would take to reach us. That is precisely what Einstein implied with the "cosmic speed limit", being the speed of light. THE VIDEO IS WRONG, PEOPLE!!

"What happens if the Sun suddenly ceases to exist?"
Space implodes as it fills the void left behind. As all this mass (mostly hydrogen) collides in the center, the impact is so great, and fast, that nuclear fusion happens and a new star is born, just like that.
In the mean time, Earth has become a new moon of Jupiter.

For everyone that thinks gravity can not exceed the speed of light are wrong.
Einstein' theory of relativity implies that the gravitational speed is equal to the speed of light thus it would have a near immediate effect on Earth

darmoors 1 year ago
Unless I'm missing something here, this video claims that the information about the Sun's sudden existential crisis travels from Sun to Earth (and other orbiting bodies) instantly or almost instantly, independent of the gravity shock wave.
This is false. Local space-time geometry (gravity) remains unchanged for the orbiting bodies until the gravitational shockwave reaches them. This depends on the propagation velocity of gravitational waves which is hard to measure and hence unknown for now.

That would violate relativity would it not?
I think the earth would continue to orbit for 7 minutes.
I think of gravity as particles. Those particles can't know the sun is gone for another 7 minutes.
Also, I question how the mesh's dent flattens out. Perhaps it simply becomes less dented. Again, I think of it as particles that have to disperse.
