weightlesness?

Question

if you have a technology that could shield a ship in space from its own mass makeing it seems as though it had the mass of a molicule or less then you should be able to push it toward near the speed of light since it would seem as though it had no mass. IM just thinking this might be how aliens travel at the speed of light or you know close to it. they would have no problems because of the time dialation. they say if you wanted to travel near the speed of light you would need tons of energy. but it would be like scaleing it down to moveing a single molicule with all the power of a nuclear power plant. its interesting because they have been able to produce fields where the objects in the field lose weight. so in space if this was perfected it would be like reduceing the effect of its mass.

Answer 1

There is a solution of it, but human would at least need to go on the edge of a black hole. We need extensive experiments on the black hole to prove controversial theories running since its inception or identification. If a characteristic of a black hole is the end of space and time, we must evaluate the concept of traveling through it and find out the new dimension of the speed, probably larger than the speed of light. If time ends there, the age of a traveler through it will remain constant and will travel in the future due to extremely powerful gravity, that will push the traveler at the speed that we cannot even imagine. If black hole has a starting, it should have the end too. Take an example of the black hole in the center of Milky Way. Suppose if we calculate the depth, it should not be larger than the total thickness of the Galaxy. But, the controversial theory is unable to prove it. To my understanding, all black holes of the universe are tide with each other. If we start traveling through one black hole, we may probably come out from the galactic centre of Andromeda or the other. This travel should not take more than a fraction of a millisecond for a traveler. But, practically, the earth would have crossed millions of earth years. This calculation is mind boggling and not supported by any realistic experiment. For it, we must experiment on the black hole.

Answer 2

Absence of weight is not necessarily absence of mass. for example, if two opposing gravitational fields interact, you may get a small zone of weightlessness, but the mass doesn't disappear. So, unless you can do something to make the mass disappear, your dream will remain a dream.
