Can any object with negative mass move faster than light?

Answer 1

NO! According to relativity theory it is not possible for anything with mass to travel faster than light.

However there are particles that have been hypothesized(but never detected, so they may not exist) called tachyons (meaning "the fast ones") that always travel faster than the speed of light.

Answer 2

No. The speed of light is the, for lack of a better term, the maximum speed limit of the universe. The closer an object gets to the speed of light, the slower time passes for that object, thereby actually reducing it's speed, keeping it from reaching the speed of light.

The fact of the matter is it will take an infinite amount of energy to reach light speed sice there is no such thing as infinite energy lightspeed is impossible for anything that has mass

Answer 3

Theoretically, yes, but that would require us to reduce the weight of whatever is gonna travel at those speeds to absolute ZERO and/or we will need to have an unlimited power-source to propel it (Both unlimited in capacity and in the amount of energy it provides at any given time).

Since making something weigh "nothing" is currently impossible and there is no such thing as "unlimited/Infinite" in a limited and finite universe, it's practically impossible.

It would be much smarter if we would bend the rules of physics than to try to break them.

Answer 4

It is currently believed unlikely that anything can move faster than light.

It's also currently believed that nothing has "negative mass". Even tachyons, hypothetical particles that can only travel faster than light, don't have negative mass (they have imaginary mass, which is not the same thing).

Answer 5

Under current scientific understanding, objects with negative mass are purely theoretical and have not been observed or proven to exist. If they were to exist, the theory of relativity predicts that objects with negative mass would always travel slower than the speed of light, just like objects with positive mass.
