I find a way to go faster than light

In summary, the theory of relativity states that the speed of light is the ultimate speed limit in the universe, making it impossible for anything to currently travel faster than light. There is no evidence or theory to suggest that we can break this barrier, and attempting to do so would require an infinite amount of energy. While it may be possible for our understanding of physics and technology to advance in the future, it is unlikely that we will ever be able to travel faster than light. If this were to become possible, it could have significant consequences on our understanding of the universe and the concept of causality.

Ok you can't go as fast as light. How about two rockets going at 75% of the speed of light in opposite direction? then an observer in one rocket will see the other rocket going faster than light.

not so fast...

The relative speed of the rockets will only be 0.96 c. Remember, speeds are added (per Special Relativity) like this:
[tex]w = \frac{u + v}{1+\frac{uv}{c^{2}}}[/tex]
not like this:
[tex]w = u + v[/tex]
 

1. Can anything travel faster than the speed of light?

According to the theory of relativity, the speed of light is the ultimate speed limit in the universe. This means that currently, nothing can travel faster than the speed of light.

2. Can we ever break the speed of light barrier?

At this point in time, there is no scientific evidence or theory that suggests we can break the speed of light barrier. It is considered to be a fundamental law of the universe.

3. What would happen if an object traveled faster than light?

According to the theory of relativity, as an object approaches the speed of light, its mass increases infinitely, and it would require an infinite amount of energy to reach the speed of light. Therefore, it is impossible for an object to actually travel faster than light.

4. Is faster-than-light travel possible in the future?

While it is currently not possible to travel faster than light, it is always possible for our understanding of physics and technology to advance in the future. However, it is unlikely that we will ever be able to travel faster than light due to the fundamental laws of the universe.

5. What are some possible consequences of faster-than-light travel?

If faster-than-light travel were to ever become possible, it could have significant consequences on our understanding of physics and the universe. It could also potentially have implications for time travel and the concept of causality.
