Man made object that travels faster than light?

Answer 1

Currently, there really isn't anything that can move faster than the speed of light, man-made nor natural, possibly not even alien. In theory, warp drives would work, but would require enormous amounts of fuel, which we currently do not have. Also, in order to move faster than the speed of light, you would have to accelerate some constantly to move at the speed of light. The faster something travels, the harder it is to move it faster. Consider this: If you are pushing a stroller with, lets say, a Rubik's Cube inside it, then continue to push it faster and it will be increasingly harder and harder to accelerate the item. Soon you'll be pushing a car, then a skyscraper, soon the mass of the moon and then the mass of the sun and whatnot. Which means the faster an object moves, the more mass it has and the more force it will require to accelerate it. Now, at the speed of light, the object would be at infinite mass, therefore infinite force, to continue to push it, which does not exist in a finite universe.

Answer 2

With our current technology the answer is: NO.

Also, by the theory of relativity, you require an infinite amount of energy to go the speed of light, assuming you have non-zero mass, so it is impossible to go faster than the speed of light.

Answer 3

The speed of light is about 299,792,458 metres per second, so 299,792,459 metres per second would be a faster speed than this. Whether anything csan travel faster than the speed of light depends on your viewpoint - speed is usually measured in terms of the distance travelled by an object (or particle, or packet or wave) relative to a fixed point, such as a planet or a starting line. But if you have two objects moving at the speed of light, then their speed relative to each other would be TWICE the speed of light.

According to general relativity, space can expand with no intrinsic limit on its rate. So, two galaxies could separate faster than the speed of light if the space between them grows. Theoretically there is nothing that prevents two objects from moving away from one another at something greater than the speed of light. But if that is the case, neither of them started out in the other's intertial frame of reference. No object can accelerate to the speed of light, relative to its starting frame of reference.

A type of particle with an imaginary mass ( m = i and square root -1 = i ). So right now : nothing can.

there is something faster than light that is graviton. The particle that is responsible for gravitational force so this particle must exist. However its existence is not yet been experimentally proved.And its speed is predicted to be about 10,000 times that of light (much faster than light).

Answer 4

Although it is usually believed that nothing can travel faster than light but it is not necessarily true. Although it is impossible to accelerate an inertial object to speed of light, it is possible that there are some particles which always move faster than light. Such particles are known as Tachyons.

It's worth noting that tachyons are at this point purely hypothetical; there's no proof, or even evidence, they actually exist... we just can't completely rule them out on the basis of present knowledge. It's also worth noting that if they exist and are capable of interacting with normal matter it raises the possibility of causality violations. In other words, even if they do exist, we may never be able to detect them.

Answer 5

No, because by travelling faster, you gain mass (substance), and if you travelled at very close to the speed of light, you would need more energy than there is in the Universe too make you go even faster.
