Could light speed happen by engine?

Question

If anything in the vacuum of space that was set into motion will travel at the same rate of speed constantly as the initial thrust, could light speed happen by an engine that was constantly pushing the object?

Would the speed of the object be grow exponentially faster by the second? Could speeds greater than that of Light also manifest?

Answer 1

No, this is impossible.

With constant thrust, the ship's speed will start off increasing in a linear manner. However, as the ship gets closer to light speed, the ship's mass actually increases, in an asymptotic way, to infinity. So, your thrust provides less and less acceleration the closer you get to light speed. At light speed, the ship's mass would be infinity, so it takes infinite energy to reach this speed.

Answer 2

No, according to the special theory of relativity, it would take an infinite amount of energy to get a massive object to move at light speed. Since no engine can produce an infinite amount of energy, this is not possible.

Answer 3

No. As an object approaches the speed of light its mass approaches infinity. Therefore an infinitely strong force is required to accelerate an object to the speed of light.

Answer 4

To go light speed is not impossible it's just improbable. There is no rocket or let alone engine that can go that fast, or a human that can with stand the G-Force. But the energy to do it is already here and ready to use, it's just we don't have the capable rocket to do it. But in recent years we did go a lot faster than MACH 1. We have I believe reached Mach 9 maybe even 12 but if you go on-line and check Discovery Channel or TLC, they have done a show on a place that test rockets and they have made ones that go fast enough that a person can probably never ride one.

Answer 5

no, the mass would be infinite
