    We know that time is effected by gravity; the greater the gravity, the slower time flows relative to things experiencing less gravity. My question is, what would happen if you could somehow form an anti-gravity field? Would you appear to age faster to a person outside of the field? What would your perspective be like? Would the outside universe appear to freeze in time as you continued to age?

    Water nosfim please state your posts are theory, this is likely to be moved otherwise as woo.

    Interesting point, never thought about that. If by "anti-gravity" you mean space-time curvature with an orientation opposite that which happens for "normal" energy distributions, then yes, in theory time should "speed up" as compared to some observer far away.
    Bear in mind though that you would need some form of "exotic matter" to generate such an effect.

    They would have to be far away since it would be repulsive- no one would want to go near it.

    Ha ha, true
    It is an interesting thought though, never considered that before.

    I was working a while back on a negative energy problem that fried my brain. No s'rsly. Like an egg.

    I gave it up as a bad job, not the least because it had no practical purpose (Negative energy laser, anyone?) but because I couldn't seem to get myself to focus on it mathematically. I kept getting distracted with odd questions like, "Hold on, if I applied negative energy to a bomb, would it suck me up inside it?"

    I decided that I didn't want to know.

    This is a little fantastical but maybe worth a bit of consideration (these are the things that pop in my head as I drift off to sleep XD): I'm sure you've all seen the "bowling ball on trampoline" analogy of gravity; could it be possible that dark energy is a mass on the "other side" of the trampoline (universe)? As the Bowling ball on side A of the trampoline pulls marble A too it, marble B on Side B would be repelled. Perhaps, and this is a pretty big perhaps, what we experience as dark energy in our universe is just regular ol gravity in the universe next door and vice versa. I haven't worked out how dark matter plays in to this scenario though.

    p.s. I'm so glad I found this forum, I just don't have the opportunity to discuss such things in the real world! Also, I'm glad that I'm not the only one who couldn't understand what the F Mr. Water Nosfim was trying to say

    You are truly glad about a lot of things! Not bad although. Αη∂ Ƒor the above,remember both an observer in the field αη∂ outside the field will think the other observer's clock is ticking slower!(Vice versa). So to both A is travelling faster than mr B αη∂ B feels he is travelling faster than A. Same old αη∂ ever exciting reality.
