Faster than light relative speeds (I know it's impossible)

In summary, the speeds of particles in a particle accelerator on Earth do not add up to more than the speed of light, even when observed from outside the galaxy, due to the effects of time dilation and length contraction. These effects become increasingly significant as velocity increases, with no maximum limit on time dilation."

solarflare, all of that is nice, but none of it supports your claim
solarflare said:
the creator said himself that it had flaws

Furthermore, that GR predicts singularities is not a flaw in GR. It is self consistent, and consistent with available evidence. This is all that we ask of theories that do not purport to be a theory of everything.

FAQ: Faster than light relative speeds (I know it's impossible)

Can anything travel faster than the speed of light?

No, according to Einstein's theory of relativity, the speed of light is the ultimate speed limit in the universe. Nothing can travel faster than the speed of light.

Why is it impossible for objects to travel faster than light?

It is impossible for objects to travel faster than light because as an object approaches the speed of light, its mass increases infinitely and requires an infinite amount of energy to continue accelerating. This makes it physically impossible for an object to reach or exceed the speed of light.

What is the significance of the speed of light in physics?

The speed of light is a fundamental constant in physics and plays a crucial role in our understanding of the universe. It is the maximum speed at which all energy, matter, and information can travel, and it is a key component in Einstein's theory of relativity.

Is there any evidence to suggest that faster-than-light travel is possible?

Currently, there is no scientific evidence to support the possibility of faster-than-light travel. While there have been some theoretical proposals and experiments conducted, they have not been able to provide conclusive evidence that it is possible to travel faster than the speed of light.

Could the laws of physics be different in other parts of the universe, allowing for faster-than-light travel?

While we cannot rule out the possibility of different laws of physics in other parts of the universe, our current understanding of the laws of physics suggests that the speed of light is a fundamental constant and would remain the same throughout the universe. Additionally, any changes to the laws of physics would require a significant overhaul of our understanding of the universe.
