If it turns out that the Higgs Boson is the key to mass, then understanding it could very well lead the way to distant space travel. If mass causes gravity by it's affect on spacetime, and gravity slows time then maybe future space travel will not be because we can achieve velocities close (or at) the speed of light, it may be simply because we can slow down time.
If we can understand mass itself, maybe there is a way to mimic mass and exert a large effect on spacetime. Then maybe we can somehow use this knowledge to mimic a gravitational field strong enough to slow time to a mere crawl. In that scenario the velocity of the ship you are travelling in is pretty much irrelevant. If it takes 1000 years (from Earth's perspective) to get to you destination, but time is slow enough that only a day has passed for the occupants then you've traveled 1000 light/years in 1 day.

speed of light travel for something larger than a photon ?
how does a body which is basically a bag of water survive the g-forces ?
never gonna happen

See this is where you are wrong and also where the understanding of light breaks down for most people. I'm certainly no expert but I'll try. The speed of light is constant and NOT relative to the observer. As velocity increases, time slows down. If you were stationary and observed two beams of light go in opposite directions, then both beams would appear to travel the same speed. If you traveled at light speed with one of the beams and observed the other, the path of light you observe would actually be different and the path would be longer but the light still travels to you at the same speed. The variable that actually changes is time. Time would slow down for you the observer, so the light travels further but at the same speed so it reaches you at the same 'time' because time has slowed for you.
I know I didn't do a good job at explaining it but refer to concepts such as time dilation and Einstein's special relativity. This discovery may still lead to distant space travel (see my previous post in this thread).

Actually, the opposite is true. The speed of light is constant to the observer. Check out this explanation from NASA: imagine.gsfc.nasa.gov...
I said "essentially" because there is one exception... the speed of light is always the same (specifically, 300000 km/s) to all observers , regardless of the speed of the observer or the light emitter (in this case, the flashlight).
