It was a gun-free zone so I doubt that they'll be able to.

What is Gravity? submitted by DireFire to AskScience

Maxus 0 points 8 points (+8|-0) ago

Gravity is best explained historically...let's see how much I can remember.

Newton's concept of gravity was that of an instantaneous force acting between two objects. In this model, it is best to think of gravity as a rope connecting two objects: (in this model) if the Sun were to disappear, the Earth would fly off in a straight line instantly. Newton's Theory of Gravity was enough to land astronauts/rovers on the moon back in the day. But it is an incomplete theory. And it doesn't say anything about what gravity is.

One thing that spelled failure for Newton's laws was the precession of the perihelion of Mercury (henceforth PPM). I'll edit this post with links a little later. The PPM is the actual shift in orientation of Mercuries orbit around the Sun, which is not fully accounted for in Newtonian gravity. It is however explained by General Relativity (GR). But before I move on to GR I want to bring something else up. If the Sun disappears in Newtonian gravity, we fly off instantly; however, as edumucated 21st centuryites, we know that it takes the light 8 minutes to travel from the Sun to Earth. Well it bothered Einstein that we'd be able to tell that the Sun had disappeared, before we could see it disappear. Especially since he had shown in the early 1900s that the speed of light was a cosmic speed limit. If that is the case how could the Suns gravity be 'communicating' faster than its light?

GR was proposed by Einstein in the 1910s. It puts forth that Gravity is just the warping of "spacetime" and the curved paths we move in space are geodesics (straight lines) on the complex geometry of spacetime. When the Sun is removed from spacetime, the spacetime ripples as it goes to equilibrium, and these ripples or waves travel at the speed of light. So that solves the conceptual problem above. Now when the Sun disappears we'd fly off exactly eight minutes later, right as the lights went out for good. And GR solves the PPM to astounding accuracy.

But it is still not a complete theory. Anything past this point is pure theory.

Particle Physics has been searching for a force carrier for Gravity, called the graviton. If this is discovered it would show that gravity behaves like every other force, through the exchange of force carrying particles at varying strengths.

String Theory proposes that all the fundamental particles of the universe are vibrating strands of energy. All of them closed loops, except for the Strings for gravity which are theorized to be open ended. If String Theory is true...well it just probably isn't...but if it were...well let's just hope it's not.

My favorite is Loop Quantum Gravity. It is IMO the most promising explanation of gravity.

I'll add links and resources in a little while!!

So much control it is scary. Winning with the Pyroblast-Deathwing combo will no health left and Ice Block activated is just precious.
