does "gravity" (whatever gravity is) insinuate the possibility of instantaneous interstellar travel?

just what the title says. i still can't understand exactly what gravity is, and we know "It" exists, but do we really know what It is? considering this "force" stretches across huge distances, through complete vaccum, and also has NO MASS whatsoever,
along with the fact that every scientific/physical barrier which has seemed to exist is always transcended 100-500 years later, i bet we will soon be able to travel to other galaxies through stargates.

how does gravity stretch through a complete vacuum?
do you mean space as the complete vacuum?
i dont believe there is gravity in space..
plus have you ever seen the movie stargate?
if you can travel like that i wouldn't want to..

In spite of what it sez on star trek there is no sign of any way of travelling faster than light. And because of basic fizziks it aint likely we'll go faster than maybe 100,000mph. So getting to nearby stars is, like, out of the question. People wanna believe there's gonna be some star trek someday but it ain't on. We R stuck here. So party like its 1999.

In science nobody knows what anything is. Everything is described in terms of other things we dont know. Forces, energy, mass... these are basic building block of physics theory, but what they are cannot be known. What we can study is how they interact, and what models predict their interactions.
EDIT - In physics definitions the effect of gravity is from the bending of space time, or the exchange of 'graviton' particles. (depends on if you are thinking relativity theory or quantum theory)

Of course there is gravity in space. Thats what keeps the planets in orbit, and galaxies together.
The force of gravity from any object (including yourself) extends through all of space.

gravity most definitely travels through the vaccum of space, e.g. the moon causing ocean tides on earth. gravity is what keeps us at the same distance (approx) as we orbit the sun.
don't assume there are going to be super bad monsters on the other side, its just a tv show. imagine if you could stargate to the Haight Ashbury planet in the solar system Hoffmann

like gravity on a larger scale that's what pulls the planets in orbit.. dude i gotcha thanks dude i understand that.
i wish i wasn't so ignorant about this kinda stuff. i also wish i had more general electives to take so i can learn about this kinda stuff.

I'm no astrophysicist, but I was under the impression that gravity was traveling FTL.
Its entirely possible I misunderstood though.

The force of gravity travels at the speed of light. Otherwise you could communicate faster then light using gravity and violate causality.

Many many very smart people think that by using a super strong electromagnetic field around something it will create an antigravity efféct and slip through dimensions giving way to intersteller travel and the billions of possabilitys for anti gravity.
There are a bunch of documentrys about a airforce carrier doing this a long ass time ago and it disappeared and ended up thousands of miles away. With people stuck halfway in walls and the floor n shit. Crazy stuff

Gravity is a weird one.. we touched on it in the physics class I'm taking.. When people talk about gravitational potential, according to this formula; GM[1/r1-1/r2], theres an absolute limit at infinite: -62.6MJ
Then as the gravitational potential approaches zero the gravitational force is really strong..

That's incorrect. There is a limit for gravitational potential at infinity = 0. It becomes more negative when you approach, for example, Earth. The maximum (negative) potential energy on the surface of the earth is -62.6MJ.
When using potential, the absolute number is of little importance, it is the slope of the potential hill that gives the gravitational force.
You can add a constant to your formula, Up = GM[1/r1-1/r2]+U0, and this wouldn't change the forces derived from it. When this constant is set to 0, the formula corresponds to a potential at infinity of 0. This is what is done in orbital mechanics.
The gradient of the scaler field(gravitational potential) is a vector field(gravitational force field). This defines potential energy.

There is an instantaneous interconnectedness with everything that exists at all times.
Everything is one. Anything is possible.
The formless substance of the universe can give heed to any possibility so long as it is created. Through vision and through action. Anything can be.

Actually...they don't actually travel faster than the speed of light, at least not locally.
A "warp drive" is a theoretical possibility.
What happens is the warp drive "compresses" the space in front of the ship while "expanding" the space behind it. Then the ship just moves along with their "impulse drive" which only moves the ship at speeds below the speed of light. Because of the compression of space ahead of the ship, the ship is able to move much slower than c locally (say, half the speed of light) but moves much faster than c over long distances (again, dues to the compression/expansion of space around the ship).

I am a hopeless optimist when it comes to the abilities of science.
I wholeheartedly believe, admittedly w/out any evidence, that FTL travel is possible and will be achieved at some point in the relatively near future. (Few hundred years?)
Don't ask me why, just eternal optimism in the ability of combined intellects to solve problems that seemed impossible to earlier peoples.

We were taught that you start at infinite and count backwards.. an inverse scale.. it had a special name, I can't remember what.. its been a while.
For the earth the Limit for the gravitational potential was -62.6MJ.
-> G = gravitational constant, M = mass of earth, R = radius of earth
-(6.67x10^-11)x(5.97x10^24)[1/6.38x10^6 - 1/infinite]
= -62.414x10^6 J.
At the center of earth (i.e a radius of zero) to a distance of infinite, the gravitational potential become GM[1/0 - 1/infinite]
I might just have my shit hella confused, but still I'm gonna try and argue

You're thinking that a technological advance will allow FTL. As far as we know, this is not a limitation of our technology, but a fundamental property of the universe (like arythmatic) that no technological advance can bypass.
What you're saying is logically equivalent to the following statement:
I wholeheartedly believe, admittedly w/out any evidence, that one day a technology will exist that will permit one to place 2 apples in an empty box, then add (arythmetic) 2 more apples, and the result of that addition will be 7 apples in the previously-empty box.
See the problem with that statement? Technology can advance without bound, but it can never bypass the rules of arythmetic. 2 + 2 will always equal 4, and never 7, no matter how many advances we make.
But, I NEVER say never (except to illustrate a piont ^^^). That word is profanity to a scientist. That's why I like to say almost-certainly never.

Heh I wonder what you were going on about with 'arythmetic' 
Maths is a language we have developed to describe phenomena... as we evolve, it evolves. However, as it was designed by us, as part of the system we are trying to describe, there are many fundamental limitations to our understanding. Its like the eye trying to perceive itself, or thinking about thinking...
Any knowledge we do have of our universe is interpreted by us and applied to our situation.. This is why we base everything we know on models of reality.. we are unable to to view the universe in such a way that allows us to see the whole picture, so we create models of situations and dismantle them, factor by factor, until we have a concept of the underlying principles.
My point being, that no man made discovery is a universal truth. Maths is simply our way of describing phenomena.. The probability of 2+2 equaling 4 is very likely, however, depending on the on situation at hand, I imagine there is some circumstance in this vastness of unpredictability that allows for 2+2 = 7.

Yes, so the gravitational potential would go to infinity when the radius of earth would go to 0. (you would also have to compress all mass of earth into a singularity, digging a tunnel in earth to get a smaller r doesn't work).
I think we think the same now

I understand this. I absolutely agree with you that this seems impossible, given our current understanding of physics. But I am not so vain as to think that everything we know now is correct. It seems correct, but who is to tell what future discoveries will be?
I find it entirely plausible that at some point in the future we will be able to pull, poke, prod, or otherwise cause the laws of physics to bend to our will.
Obviously, this is conjecture. But I have great faith in the ability of the human intellect.

I think your estimate is a tad on the low side... The Voyager spacecraft sent up the the 70s left the solar system traveling over 35,000 mph. I'm pretty sure we can cross 100,000. :-)
