    Target Distance and Light Travel: The Impact on Spatial Position

    If you mean my question, then I meant the rocket and sun are on the same side, practically next to each other.

    Target Distance and Light Travel: The Impact on Spatial Position

    Forgive me, but I've been reading with interest, and am having difficulty getting it to reconcile. With a similar example, say we have the sun, Earth and a rocket ship armed with a laser. The Earth is moving away from the sun at 18.55mps (assume this is in a straight line and ignore Earth's...

    Energy Storage & Mass Change: Is There a Link?

    LOL, now I need clarification, I was always under the impression that the more energy a system has, the more mass it has. (although only very very slightly) ie, a charged battery has more mass then one with no charge, so i assumed it was the same for a compressed spring.

    Energy Storage & Mass Change: Is There a Link?

    The mass of the spring will increase when compressed as the system contains MORE energy. And yes every energy storage/change will have an associated effect on mass.

    How does this website read your mind.

    Thanks kof9595995 that explains it perfectly, isn't algebra wonderful. I've just never seen it applied like that before. fleem, that's an interesting site too, very clever.

    How does this website read your mind.

    Hi , A friend sent me this website, and I was wondering how it worked, http://www.regiftable.com/regiftingrobinpopup.html obviously it can't read my mind, and its some kind of mathematical trick, I can initially see that all the answers i come up with are 18 apart and that gift is...

    What happens when you apply a force in space over infinite time?

    so what would show on the speedometer of such a spaceship, would you just approach 299 792 458 m / s and sail past it without noticing?

    Why Do We Measure Distances in Light Years Despite Time Dilation?

    Hi, This is probably a beginners question, but ill ask it anyway as it has me confused.I have read quite a few posts from clever people here (so I assume its correct) that the closer to light speed you get, the slower time gets, and also distances get shorter. Effectively meaning that, say for...

    General newbie questions regarding the speed of light

    Hi Newb good question, as I am a beginner and asking myself the same sort of questions. Although I am not sure you will get the answers you require to make things feel right in your head. I think what happens in the universe is so different to what we feel is 'normal' in our everyday lives...

    Silly question about special relativity

    Cheers JesseM, I actually read that post and understood it, which is amazing for me. Very clear and a good example. (I tend to just read here, but that post I thought deserved a thank you.) One question, after the signal and Bart have set off, will Bart not see the signal traveling away from...
