Science & Mathematics - 28 January 2007

I've heard of the concept of astronomers detecting microwave radiation from the big bang. But I don't know how this could be. If everything was created in the big bang, which was an explosion from a single point, and nothing can travel faster than the speed of light, and the microwave radiation travels at the speed of light (which it must as it is electromagnetic radiation) then how could we get in front of it so as to receive it now, without us travelling faster than light to get there?

I expect the answer probably involves relativity, which I can't easily get my head round.

eh.. just watching a bit of 'terminator' lately - kinda got me to thinking about our level of technology... dont quite understand where technology stands.. or what keeps it in check. a kid can build a little battle bot - why.. or why dont forces use mechs? does someone somewhere? or are they just waiting around for nanotech so they can build on a much more impressive level?
kinda just thinking to myself - wouldn't mind someone else's thoughts.

Find all real or imaginary solutions to each equation. Use the method of your choice.

w^2 = -225

√7x + 29 = x + 3

Solve each equation by the method of your choice.
2y^3 - 3y - 6 = 0

Determine whether the graph of each parabola opens upward or downward.

y = 1/2x^2 + 3

Please only reply with legitimate responses, this is serious!

Thanks again!

A couple of months ago I recieved lots of answers telling me that its impossible to be at the 'end of a rainbow'. I accepted all answers withgood grace. However, I recieved an e-mail from someone who, with her mother on holiday in Turkey, had the same experience as me and for the last ten years had not been believed and was relieved when she saw my question. Are you sure we didn't see what we say we saw?
