Assuming the sun vanishes instantly

FYI gravity is not a force, but a warping of space itself.

Nigga What

No, the electro magnetic waves are same as fast as the gravity waves.

>I assume it'd take us more than 8 minutes to realise that the Earth is going to outer space, but around 8 minutes to realise that the Sun's gone.

Assuming the sun went "pop" and just vanished, we wouldnt know for the 8 mins it takes the light to get here, and of course, while we'd instantly see the sky just turn to night in an instant, we'd probably not know the sun's vanished - after all, its not exactly likely.

Earth, as a planet, would cease orbiting the point that the sun was in, at that moment too. but we'd probably not realise that was happening, simply because we'd be trying to work out the more pressing question of WTF has happened to the planet's source of light and heat. I expect we'd probably end up managing to track known positions of mars, jupiter, etc, and might *just* manage to spot them, (not easy with no sunlight reflected off them) and confirm from their positions that they, and we, are all heading off in different directions, no longer constrained by gravity.

That gravitational influence stopping happening would propagate at the same speed as light leaving the sun's point - so, 8 mins for us, 12.6mins for Mars, 43mins for Jupiter. How long it would take for us to realise it is a much harder question.

And honestly, the bigger question is, would anyone care, given that without the sun, we as a species probably only have a few days to live before mass extinction starts to kick in, and the planet's surface begins to freeze...

Exactly.
Mass creates gravity.
... mass more or less = gravity

I'm just curious about the gravity bond over massive distances, like between milky way and andromeda. Or galaxies at opposite sides of the universe. Or even outside the observable universe. Is thier gravity removed from our equation?

Wouldn't that mean we could send signals faster than light with gravitational waves?

No, because gravity waves have been confirmed to move at C by LIGO and VIRGO inferometers. That guy is simply wrong.

yes
gravity propagates at the speed of light. So it would take 8 minutes for earth to no longer be held in the now non-existent gravity well.

I know math and those aren’t integers, theirfore they cannot be modified by human cognition.

8 min a hour, where the warm is.

Waves of what?

Matter.

define 'vanishes'.

I have not confirmed this but according to some of the posts above the effects of gravity propogate faster than the speed of light.

There is much that we dont know about quantum physics.

space is empty

*poof*. Gone.

>Dark matter

waves is a verb

They travel at the speed of light

Gravity is not a force.

An object that has mass "bends" the "direction" of the space that an object is moving through even if that object does not have mass (ex: light)

>Gravity is not a force
So why am I unable to fly?

Surely there is some force holding me back from my dreams

Gravitational force.

Normally, gravity is a constant. and therefore there isnt a wave, as such. to use an analogy, if waves are a push of water, swelling and ebbing away, then gravity is normally a consistent flow, like a river.

gravitational waves only happen when certain events take place, for example, two black holes merging, when they orbit each other, and then finally collapse into each other's gravity well, there's a sudden burst of gravitational force - a gravity wave. One such gravitational wave was detected by the LIGO detector only days after it went online.

not a force, an acceleration

Who think was him...?

If the earth was able to shoot off at the speed of light, we'd be able to always stay where the light is

It would take a lifetime for the environmentalist retards to realize we should have chosen nuclear power all along..

but then the light would be red-shifted to the point of no longer being visible either.

right, at 8 minutes an hour where the warm is

Its this tard again

>Is thier gravity removed from our equation?
No, the gravity is still there, but very very small over such great distances. Just like the light from extreme distances is still there, but very very small, and can only be seen when using the most advanced telescopes.

kek i remember this

No, it hasn't.

So, gravity is a noun?

Nouns are "person, place, or things".
Gravity is definitely "a thing," and therefore can be a noun.

GO read a book, don't eat them

Sorry, but I have to ask this question. Is Gravity in the room with us right now?

Although I am inclined to agree with those who say eight minutes, because that is how long it would take for the gravitational waves to reach the Earth, to the extent that THAT is probably the best answer to a trivial and fatally flawed question

..... the sun cannot just vanish - that is simply impossible within the known laws of Physics.
In order to give a proper answer to the question, we need a plausible mechanism whereby the sun could be deemed to have "vanished", maybe :

(a) a high speed wandering supermassive black hole has approached sufficiently close to the sun to absorb it completely - in which case the resultant warping of space causes the Earth to be likewise pulled into the resultant black hole;

(b) the sun (somehow) runs out of energy and collapses into a neutron star with the same mass as it had momentarily before it "vanished", the Earth would then continue to orbit the neutron star at substatially the same radial distance from it;

(c) the sun runs out of sufficient energy, and becomes a red giant - at some time shortly after that change, the Earth is enveloped by the rapidly expanding red giant and is vapourized virtually instantaneously;

(d) all the particles composing the sun disappear into another dimension, simultaneously within the concepts of quantum uncertainty, in which case we might as well say that all the planets previously orbiting the sun in "our dimension", suffered a similar quantum uncertainty jump into that other dimension and similarly vanish (from the perspective of the frame of reference of an independent observer, perhaps on a habitable planet orbiting Alpha Centauri in about four and a half solar years when evidence of that mysterious disappearance of the solar system managed to reach "him" in order for "him" to perceive that strange and inexplicable vanishing event.

You aren't smart
Stop repeating shit You misunderstood while watching entertainment documentaries

yes, but always at 8 minutes a hour.

>we need a plausible mechanism whereby the sun could be deemed to have "vanished"
no, we don't need a plausible mechanism, because that is not the point of the question. It's the same reason that thought experiments in physics consider frictionless surfaces and no air resistance, etc. It's to narrow the focus on just one aspect of the investigation.

>not integers, humans can't modify them
i suppose you can't solve 9.2+0.8 then?

>minuets

FFS

My initial point was that the event is IMPOSSIBLE within the laws of Physics. I understand them well enough to give a tongue in cheek answer which neither more, nor less, implausible than the initial premise.

> TL DR : fuck off.

i mean he's right technically, but it's functionally near-identical to just considering gravity a force.

gravity is a noun; it can be the direct object of verbs ("gravity went away"). it it not a verb. you can't say something is 'about to gravity'. the very fact that we can talk about gravity ITT (as opposed to talking about 'gravity-ing' or 'gravity-ness') proves that the word gravity is a noun.

Can the arts grads please go argue in the hallway there is science going on in here

Eight minutes is time enough to listen to this:

youtube.com/watch?v=2AZOknKotVc

twice before we realise that the sun has disappeared.

you've never seen gravity, only its effects.

yes, it has.

>gravitational waves
Does not exist.

Literal junk science.

It's been a while since I've studied physics, but I'd say yes, it would take 8min to experience the loss of the sun.

According to the general theory of relativity, c is the universal speed limit. Gravity and light travel at c, in a vacuum. Where things get funky is the elasticity of spacetime. If a massive object, such as our sun, were to vanish, would spacetime snap back to flat? Or, would it sort of oscillate back and forth until it settles back to flat. Think of dropping a rubber ball, and the ball bounces multiple times, losing energy with each bounce, until it comes to rest. If the elasticity of spacetime is more like the later, than the former, we would still feel the effects of the sun vanishing, then continue feeling the effects of the "ripples" in spacetime, before it finally rests.

Ding ding ding. We have a winter! To believe that “gravity waves” exist is quite retarded (legit the “detection” systems are a joke). Actually it might be even more retarded to ascribe C as the propagation rate for this imaginary wave. In all reality, if the sun disappeared everything would react INSTANTLY as that is the true speed of gravity. Even fucking Newton knew this: it’s called IAAD (instantaneous action at a distance). Now everyone who thinks gravity is a wave please go kill yourselves: your so stupid there is no hope for you. Just go die and restart, hopefully, less stupid.

He's not right at all
The bending of space does not refer to space actually curving. It's a visualisation for people that wouldn't understand the proper explanation.
Gravity is not curved space.

Dumb AND angry
Bet everyone enjoys your company

The verb would be gravitate

Right......Science for Millennial, by Millennial.

No, it hasn't.
They even admitted what they detected were vibrations from a train track that goes almost directly over the tunnel
Read beyond the headline next time

Yea Forums won't be helpful go to

You.have never officially studied physics
Stop talking shit

Are you full retard friend? When IAAD and Neuton are millennial, I think you might need some cyanide. Plz suck a tailpipe and start your neural network over. It’s way fucked and you’ll be better off starting completely over.

and you've never seen a vagina, it's still a noun tho

8-year-old logic aside, invisible things can definitely be nouns. just because something doesn't have mass or take up physical space doesn't make it a different part of speech.

anyway, since typing 'define gravity' in your addressbar is apparently too hard for you, i've done it and screenshotted its definition. guess what part of speech is listed?

please stop bringing in facts from your 8th grade science class. remember, it's the same place they taught you electrons were only particles and nothing more, which followed literal circular orbits around atomic nuclei.
en.wikipedia.org/wiki/General_relativity
this was theorized in 1905 or earier. it's not news.

muh facts i don't like aren't true because i don't like them

Why the quotes over people places and things?
Do you not believe nouns are actually people places and things?

Youre an idiot
Throw a ball straight up, ball comes straight down.
Not because space has been bent a full 360 degrees, it's because mass attracts mass.
Curving of space doesn't mean what you think it means, which makes your little rant rather ironic

From what I understand, as a general concept, 'information' cannot be transferred at speeds higher than the speed of light, therefore since gravity transfers information, it cannot have effects that extend faster than the speed of light.

mass doesnt attract rofl, mass bends spacetime, which causes gravitation AND time dilation.
you cant have 1 without the other as space and time are the same thing and we can prove time dilation with satellites alone.

So if mass attracts, then what causes time dilation?

I agree with you. A problem that implies an open universe has to be bound to real parameters, otherwise you can just claim that what would happen after the sun disappearing is that Superman will find another sun and bring it back into our solar system.

Maybe, to make the sun just vanish without inherently destroying the earth would be a feat alone.

Does this mean we are only going to have moonlight?

itt people discuss things they do not understand

Mass and/or Gravity causes time dilation.
Travelling at high speed causes time dilation because as speed increases, so does mass, which causes gravity, which affects time.
We have measured this with vehicles.
If you actually researched this at all, one of the first things you should've read is that space does not actually curve. It's not a literal explanation.
Yea Forums scientists every fucking time
Sonignorant they can never consider they don't actually know what they're talking about

Gravity travels at the speed of light, thank you einstein for being the genius you were.

better question would be, would we latch on to a planet in the solar system before we died a cold death.

how does mass cause time dilation?
and please dont go an another tangent about high speeds, why does time go slower close to massive objects regardless of your speed?

Also you seem to not understand what the word "spacetime" means and why the 2 words are put together.

Oh i would love to hear your explanation of what gravity waves are.

There is no evidence of gravity waves

Im no expert, but they should still have some kind of gravitational pull on us, albeit extremely far. However I only understand Newtonian Physics, I haven’t studied any Relative Physics except the basics.

did i stumble into a conspiracy theory thread?
next im sure you will tell me there is no evidence for the earth being a sphere.

>An object that has mass "bends" the "direction" of the space

But the bending (or unbending) of space can only propagate at c.

Nothing you are sst8ng has any relevance to you misunderstanding what the term curving space means, or how it relates to what you're saying even if you were correct.
The answer is we don't know why.
We know what is caused by gravity, we don't know how or why.
Do some searches on whether space actually curves, and maybe you'll see that it doesn't mean what you think it means.
It's a mathematical formula to represent the non constant passing of time on a constant path within fields of gravity.
It doesn't mean space is actually curving.
You have internet access, you can verify this yourself, but you are choosing to remain ignorant and continue repeating your misunderstood version of it

im quite aware of the representation of the "fabric of spacetime" and how its not actually like that but you can detect things like time dilation and gravitational waves, even predict them with amazing accurary, but this is only possible if you first assume that spacetime is something that can be stretched, bent, curved etc.
we know what is caused by gravity, we just dont know the link between mass and bending of spacetime, but there clearly is a link.
Sure, curving might not be the most accurate word to describe it, but i havent seen you come up with a better one.

I have checked these things many times now as this is not my first time in these threads and you too have access to the internet, so why not go and look for explanation on gravitational waves and why its called spacetime.

not space, spacetime. there's a difference. one has time. the ball moves in a straigt line through spacetime. the earth bends spacetime, allowing the ball to travel along a straight path which appears curved in three dimensions. did you even read the link?

If the sun vanishes, how would you even know where the planet is flying? We would take the moon with us.

Wow you morons call your physicists? Actually we dont get flung out into space fucking incels. Jupiter takes the role of the sun becauses of its size so everything will slowly start to revolve around it. Its not rocket physicists.

well we wouldn't take jupiter

You sir are an idiot, even light reaching the earth is a stupid arguement, seeing that the earth is moving, and the light from the sun reaching the earth being a moot point.

But where does Jupiter go...

Gravity outside the universe?

how many grades of retard are you? how exactly do you get outside of EXISTENCE? Im all for fantasy and all, but youve gone full SCIFI retarded.

Yeah very recently. There were a few theories about it for a while. Generally it was assumed that gravity would act this way but theres no way to easily test it. But they ran some tests observing a... what was it? A pulsar or a couple of black holes doing something, which showed the distortion eminating out from the event, enough to say that gravity isnt instantly transferred, but travels essentially

Did you?
There is no curve, the curve is imaginary to represent relative time differences occurring across the same distances .
On a graph or map it is drawn as a curve, with the line representing the amount of time it takes to travel the distance from the start point to end point.
The path was always straight, the curved line represents the time taken between points.

Hey guys check out this retarded boner who thinks "electrons arent just particles." LMAO looks like someone thinks hes too smart for people cuz he watched one too many quantum physics youtube videos.

Ok, the Earth just begins to move tangent to its original orbit immediately.

The siezmic activity could be devastating as tidal forces even out.
Losing a body that large, so quickly... now that would be turbulent.

Yay for sciencefags

They have detected multiple gravitational waves now. obvious troll is obvious

I will test it in universe sandbox 2, brb.

>did you?
you're great at dodging questions, i'll give you that. yes, i did.
anyway, you're thinking af a distance/time graph, which is... completely unrelated to the discussion at the moment, really. i'm just gonna leave this alone until you come up with an atual answer.

yep that's me such a big-headed showoff for discrediting the other guy's source for ignoring the truth for the sake of simplicity. how self-important can i get, doing things like mentioning that sometimes schools are wrong about things.

No, it's not a distance/time graph.
That kind of graph relies on time being a constant.
The curve you think is literal, measures time, not distance.
It's a way of expressing mathematically and visually, how travelling the same distance, at the same speed, can take varying lengths of time.
The curve is a way of making the measurement between 2 points longer.
The thing being measured in this case being time.
You've got your answer, multiple times.
You not liking or understanding it is irrelevant.

gravity slows down as it travels through glass but then speeds up to its original speed. Just like light

this. They've correlated light and gravity together from at least one of these big events. I think it did diverge somewhat, but they think it's mostly from lensing effects that impact light but not gravity.
