Researchers at Cern in Switzerland have proved the merits of a way to test antimatter as a source of the long-postulated "anti-gravity".
It's the first time that anyone has even been able to talk about doing this
I think the idea is a fairly recent interpretation of symmetry. The idea is to see if symmetry applies (or does not) to Einstein's theory. Evidence of antigravity (of this form) would show that it does. This experiment was inconclusive though.
Been reading a few things and I understand they are trying to see how antimatter and gravity interact and the hope is that it would have the opposite effect... antigravity.
Well, there is gravity in space (that's what keeps the Earth in orbit around the Sun afterall) so if you had a spacecraft made of antimatter (and this theory works) you would be repelled but it would be sort of like a billiard ball in the near term, getting shoved away from this planet then that planet and all the time away from the Sun.
If so this wouldn't work in deep space, you would need something producing gravity to repel against ie. a planet...
Well the acceleration would decrease the further away you got (and wouldn't be much to begin with, anyway). But if you were traveling from one galaxy to another you'd have a problem with approaching your destination. You'd begin accelerating away from it when its gravitational influence exceed that of your home galaxy.
Obviously the voyagers recently left the solar system so it would take while, but I dunno what kind of speed could achieved this way...
There is no terminal velocity in space (except for the speed of light). Your antimatter spaceship is being repelled by the Sun's gravity remember? There is no need to escape it. The closer you are to the Sun the greater the acceleration away from it.
Also what would the terminal velocity be in the vacuum of space? would there even be one? would it not keep accelerating until it escaped our sun's gravity?
