Interesting result that...
Confounding almost a century of Einsteinian physics, and all before dinner... How cool is that?
So, in theory anyway, FTL is possible if these results stand peer review. Then it becomes a hardware issue. ...and mankind is pretty damned good at building hardware.
That just opens of a whole universe of possibilities, doesn't it?
Maybe not in my lifetime... But barring catastrophe, our time in this nest may be finite... Here's to dreamers.

You know, it's this kind of negative thinking that ENSURES that we go nowhere as a species.
I like to think in more optimistic terms.
I still think we haven't hit the holy grail of planets just yet. Even so, there's likely plenty of hidden technology that could help us get there. The trick is to figure out how to unearth that technology for everyday use.

Not so sure about Mars anymore. Interesting to visit but living? I asked Phage why some planets have an atmosphere and keep it, and others do not. Its not gravity, or at least not totally. He said that there is either little or no magnetosphere on Mars for reasons not yet understood. In my limited understanding, my take on that was that its magnetic field is "broken" which then possibly brings us to the question of its core, which again, in my limited understanding is what is responsible for Earth's magnetic field. We might need to "fix" that first. Just theorising, not a scientist.

Good luck maintaining a speed of 299,000 MPS for 2.2 million yearsedit on 12/25/2011 by muse7 because: (no reason given)

And then theres the billions of things out in the void you can't see or detect that could rip you apart, like rogue black holes which are estimated around 10 million in our galaxy that we know of.
The further you get away from earth your chances of dying increase exponentially. Anyone that even goes to mars runs a 60% chance of dying from cancer on just the trip there alone not counting the trip back and thats if we wait till it's as close to earth as possible before they go.
Nuclear pulse propulsion is a theoretically possible form of fast space travel. Very early on in the development of the development of the atomic bomb, nuclear pulse propulsion was proposed in 1947 and Project Orion was born in 1958 to investigate interplanetary space travel. In a nutshell, Project Orion hoped to harness the power of pulsed nuclear explosions to provide a huge thrust with very high specific impulse. It is a major advantage to extract maximum energy from a spacecraft’s fuel to minimize cost and maximize range, therefore a high specific impulse creates faster, longer-range spaceflight for minimum investment....
.... it would take a Project Orion-type craft approximately 85 years to travel from the Earth to Proxima Centauri.
Ion drive propulsion, 81,000 years
Gravitational assists, 19,000 years, (Helios 1 and 2 achieved over 158,000 mph using the sun's gravitational assist, slingshot)
Nuclear Pulse Propulsion, 85 years (at 0.05c, half the speed I suggest.

man i just want to see another planet with life so bad!
even if its a hostile reptile full planet!
(long as i was observing it from afar lol)
its just the most fascinating thing in the world for me, i literally dream of what could be on a planet millions of light years away,
what kind of people.. whats there!
Mars might very well still have life underneath the ground. Doubt it will be more than simple organism or bacterias at best though.
you know i sometimes think mars was left as a warning to earth, you know what may happen to earth if we go down the wrong path
