This site: [url]http://www.transitcommandments.com/[/url] looks innocuous, but it turns out that is running on tumblr. I clicked on the link at work and got the angry corporate firewall claiming that I was trying to look at pr0ns (tumblr is considered by them to by a naughty site.)

Growing Pressure on Obama to Do Something Stupid
 
-by Andy Borowitz
[QUOTE]Arguing that his motto “Don’t do stupid stuff” is not a coherent foreign policy, critics of President Obama are pressuring him to do something stupid without further delay. Sen. John McCain (R-Ariz) and Sen. Lindsey Graham (R-S.C.) led the attack on Thursday, blasting Obama for failing to craft a stupid response to crises in Iraq, Syria, and Ukraine.

Why can we see things when light is travelling at the speed of light (duh) when things moving at the speed of light are supposed to not travel forwards in time at all to the observer, so it should never move.

Confusing.

[QUOTE]Confusing.[/QUOTE][QUOTE]I went to a job interview the other day, the guy asked me if I had any questions , I said yes, just one, if you're in a car traveling at the speed of light and you turn your headlights on, does anything happen? He said he couldn't answer that, I told him sorry, but I couldn't work for him then.

Confusing.[/QUOTE]You appear to be confusing time as measured by a "stationary" observer with time as measured by something moving relative to the observer. Another variant of the twins paradox.

Alternatively, consider something moving arbitrarliy close to the speed of light as measured by an observer. Relatisitic contraction means that it moves an arbitrarily short distance [b]from its point of view[/b] to move a fixed distance from the point of view of the observer. Time dilation and relatistic contraction are two ways of looking at the same phenomenon and are a consequence of the unification of space and time in relativity.

Paul[/QUOTE]That sort of makes sense, thanks.

Well, perhaps 110 years ago it was indeed confusing.
