Well done. 100% of being wrong after your first post. What made you come to this conclusion?

No matter your velocity relative to anything else, the speed of light relative to you (ie the speed it moves towards/away/whatever) will always be the speed of light. This is because all rest frames are equally valid, and you might as well say that everything else is going at the speed of light.

THE RELATIVE SPEED OF AN OBJECT WITH SOMETHING AT REST IS UNCHANGED. IT'S ONLY WHEN YOU'RE ADDING VELOCITIES.

The maximum possible recession speed (or approach speed, of course) between two states of motion (as it were; 'rest frames' is more accurate) is a maximum of c, and the deviation between the actual and just adding them becomes greater as you move away from relative rest and towards lightspeed.

Nope. You still go the same speed. It's just that, as I've explained before, the recession speed isn't calculated a+b; that's incorrect, and it's something you're assuming.

I personally don't see the problem with gay marriages, and even if I was opposed myself to the 'gay lifestyle', as it were, I would still support them because it's an imbalance in legality. There is legally nothing wrong with a gay lifestyle, so why there is prejudice in some areas is another matter. Of course, religions may not allow gay marriages, but that's down to the religion in question. 'There's some parts of the bible I like, and some parts I don't like'

Physics and stamp collecting.

I like pebbles.

What do you think this is, a debate forum?

Politics isn't a science, and I'd argue about the 'social' sciences.

This isn't strictly speaking an area of the 'science' forum; it's in the 'other' section. The mods forum and religion aren't science either.

This site has credability now?

The speed of light looks like the speed of light to someone going the speed of light. Look at my posts on the 2nd page, and one on this one.

Anything. It just takes an enormous amount of energy.

Perpetual motion is possible at lightspeed, because there is literally no time. It's handy that there's no time, otherwise it might be possibly for exchange particles to decay, and that would cause no ends of problems.

I wouldn't be very good atm, because I haven't played for about 9 months. Was 14 at the time though.

How are we idiots when you talk gibberish?

Don't forget the deficiencies of other vitamins. Things like ricketts await!

I find that relativistic effects are the least of your worries when it comes to the accuracy of GPSs.

If you want the example of the torch beams, then a and b would both be c. (c+c)/(1+c*c/c^2) = 2c/(1+c^2/c^2) = 2c/2 = c. So the recession speed of two bits of light travelling at c in opposite directions is c.

All rest frames are equally valid, is what I am saying.

Why not do it with the you used? 50 mph is about 22.3ms^-1. (22.3 + 22.3)/(1+22.3*22.3/299792458^2) is what you're looking for. Which is about 44.6/1.0000000000001, or thereabouts (0's aren't exact, just 'a line of zeros'), which will be just less than 44.6ms^-1. And after one hour, they would be about 99.999999999999998 whatever miles apart.

What happens to me, I don't have a website :(:(

I play Go, although haven't actually played a game in over a year (alas, being apart from the GoSoc has hampered my game). It's a game in the same general area as chess; a tactical board game based on a grid. However, Go is about area control, and the like. Google for it.
