it can't for now
Absolutely not - Antimatter is a hypothetical form of matter that is as yet unsubstantiated. Answer It's possible but not probable. And antimatter is not hypothetical
It is not possible to propel an aircraft using antimatter because the technology to create and store antimatter requires equipment that is very large and massive (not able to be carried in an airplane), because there is no current technology for long-term, portable storage of antimatter, and because current technology permits creation of antimatter only in exceedingly small amounts.
According to current scientific understanding, antimatter does not move backwards in time. Time travel is a complex concept that has not been proven to be possible with antimatter or any other known particles.
Scientists admit that there may be as many as 27 'parallel universes' to our own. It is quite possible that there is not only an antimatter universe, but parallel universes to it.
well.. it might have something to do with that protons are bigger than electrons in matter and that works out better than antimatter where positrons are the smaller in mass.
Watch "Angels and Demons" Starring Tom Hanks. It deals with a bit of catholic stuff, but the main focus is using antimatter as a power source and weapon.
So far, there is NO known way to change the past.
As much as 50% of energy produced in reactions between nucleons and antinucleons is carried away by neutrinos in these applications. It is theoretically possible to retain as much as 100% of the energy in an Antimatter reaction.
who knows, your guess is as good as mine, but i believe that matter isn't prevailing, maybe there are more antimatter than matter in some distant planet or something.
NO they are not possible to build safely because the antimatter would explode the UNIVERSE and no one wants that
Most spaceships are unpainted.
