Even if we colonize Mars, we will never have instant communication between Mars and Earth, due to the cosmic speed limit.

>>4103565
not this shit again, this must be some of the worst reporting ive ever seen. THE SIGNALS DON'T TRAVEL FTL! what they do is they have a FTL polarization current in the device that generates radio-waves, these waves travel AT the speed of light, the polarization current doesn't contain any information, and the electrons don't really travel faster than light, its like shining a laser on the moon and then moving it and claiming its moving FTL on the moon. he reason why this can be used for communication,m is because the radio waves can be squished into little packets that dont decay like 1/r^2 with distance like normal waves, but decays like 1/r. meaning the original signal doesn't have to be so strong and can be transmitted farther and faster (but not FTL).

>>4103659
no its not, you need a classical signal along with it so send information, the classical signal is still slower than light. when the classical signal gets there then the rest of the information if sent "instantly" but the whole proses still takes the same time it would have if everything was sent with a classical signal.

if we could phone mars how far behind or a head would they be to us in time wise.

Like am from the uk and I think america is like 9 hours behind us,how would it work if I was trying to phone someone on mars ?
WOuld they be a a few days a head or behind me ??

"Voice of the Distant Star" is an anime dealing with this.

Basically boy/girl are friends, girl gets selected to join the space army. Years passby on Earth, while only months pass in space. They however meet each other again, only the girl is still the same age and the boy is now a man.

The 360 was heavier when you added in the AC pack, which was built into the PS3. I always thought that was rather disingenuous of the Xboxfags saying "lololol xbox heug? whos big now!" when they still were when you added that in.

It's like taking the motor out your car and saying it is lighter than your friends. And yes it is a fair analogy, you can't use the car without the motor, you can't use the console without the power brick.

>>	Anonymous Mon Dec 5 09:02:19 2011 No.4103803 You can't send information over entangled particles. You can measure one and know the measurement of the other, but disturbing one particle's charge/spin/whathaveyou breaks the entanglement.

I love analogies but when we discuss physics we must be specific and technical.

Because matter doesn't exert momentum onto photons, and we know this because of Einshtein's special relativity. As far as I know, relativity is pretty sound.
