If our spaceship could generate a net force, couldn't we eventually move at the speed of light?

Question

hi, I am new to space travel and physics, so please forgive me

assume we have enough fuel in the spaceship as necessary,

Answer 1

As you approach the speed of light, your mass goes towards infinity. So Newton's F=ma shows that the force required to keep accelrating goes to infinity. It would take an infinite amount of power to actually reach the speed of light. At the speed of light your mass is infinite so your gravitational pull would be infinite and the entire universe would get sucked into you.

That would be a bad thing.

Answer 2

The restriction on the speed of light is not a power restriction,it is a time restriction.
Time is a quantum entity,it has a limit to how small it can be.
If you try to reduce the limit it goes out of existence.
anything traveling through space is an incident that takes a certain amount of time.
Anything traveling at the speed of light is at that limit.
If you try to speed it up you are attempting to force it to exist for a stretch of time that can't exist.

Answer 3

By current theory, as the speed approaches the speed of light, the mass approaches infinity. One can't accelerate an infinitely heavy body.

Answer 4

Assuming we can have the necessary fuel (maybe a new type of engine) we would be able to travel at the speed of light. I doubt we would be able to do anything other than move in a straight line, and I doubt people would survive such a trip, but in theory, it is possible.

Answer 5

Nothing can move at the speed of light, other than light. Basically because as a body of mass approaches the speed of light, its mass approaches infinity.

Answer 6

Yes. It has been established that photons have mass. Theoretically anything with mass can be used for power.

Answer 7

No, you cannot.
