    Re: Fastest thing in the whole universe!

    Gravity curves spacetime, light travels in spacetime, so in principle gravity being "faster than light" in certain conditions is merely "cheating" so to speak so it doesn't violate General Relativity.

    Force has propagation speed, it simply doesn't have propagation delay like Light

    Technically all brain processes are merely electrical impulse so the "speed of thought" is the same as the speed of light

    Re: Fastest thing in the whole universe!

    gravity is not a "thing" its a force as KillerMongoose wisely noted
    and even most powerful gravitational pulls/pushs are hardly half as fast as the speed of light

    however there is another force called 'dark energy' which accelerates the expansion of the universe, and this acceleration is believed
    to be much faster than SoL

    Dark energy and dark matter are currently unfalsifiable and remain only as theoretical models atm.

    Energy is much faster than light. At big bang, in one trillionth of a sec, million of light year distance was reached so energy>light.

    everything is a theoretical model until we are given a valid proof, which takes time and patience

    Re: Fastest thing in the whole universe!

    It depends on the gravity, I mean, gravity on earth is 9.81 m/s, on the moon it is about 1.62 m/s, considrably lower then on Earth, while the gravity on the sun theoretically will be 28 times bigger then the earth. The bigger a planet is, the higher the gravity on it is.

    But if you take black holes, there is the gravity so high that light can not escape. Again, it all depends on the fact what one takes as 'gravity'
