Actually, this may be earth's messenge to outer space as well... once mankind blows itself up, pieces of earth will journey through space for ages and possibly will land on another earth to suggest that there once was life elsewhere.
It's even possible that such a meteorite has happened to earth and was the carrier of the life that afterwards developed. Maybe by blowing earth up, mankind will therefore manage to colonise another planet? Given that life's sole plan is to spread, this might be a perfectly logical decision.

I've never heard that antimatter could move faster than normal matter. AFAIK, antimatter didn't have any properties different from matter (except the "polarity" so to speak, obviously).

You are correct about that.

Things CANNOT travel faster than the speed of light.

the only reasonable (IMO) method of traversing vast distances basically come down to the use of Wormholes

Personally I wouldnt be particularly willing to be the 1st to try and traverse such an anomaly.

it is possible to move faster than light speed! you have to use anti matter. its a process where protons or nuetrons are speeded up to very high speeds and then slam into something and create an antimatter or something like that...


I believe you are refering to a particle accelerator, these cannot accelerate particles past the speed of light, primarily because its impossible to do with any technique and secondly because the accelerator uses magnetism to propel the particles at higher and Higher velocities, considering that magnetism is an elecrtromagnetic energy and has a maximum velocity of the speed of light then it wouldnt work from our perspective...... but then the law of relativety says that if you were to travel at 99% the speed of light and someone stationary was to shine a laser beam in your direction of travel you would see the light pass you at the speed of light relative to your own speed...... Relativety makes my head hurt  :'(

Actually tachyons are said to travel faster than light although their existence has not been proven.

That's because time will be passing at a different for you, the light and for the shiner of the laser. It does work out kinda xD

And tachyons are strange (if they exist) because they can't travel slower than c.

Doesnt your time stop  relative to those who are stationary? Time slows down as you approach the speed of light, eventually stopping? (for you, not the universe)

Well nothing is stationary. A big part of relativity is that there's no way to tell who's moving away from what at what speed, only what's moving relative to another. Same with time, your time slows down relative to the time of the object you're comparing with, and it would theoretically stop at light speed.

yup, thats what I meant by:

I didnt follow it up particularly well with my second sentance lol
