Hello everyone,
I'm new to this forum. Can you clear my doubt about Einstein's special relativity theory?
It says anything can not travel more than the speed of light. because, when velocity reaches the speed of light, mass of that body reaches infinite and it can not accelerate. but, consider engine pushes a rocket, mass of the rocket is always same with respect to engine of that rocket. because, velocity of that rocket is zero relative to engine. so, engine can accelerate rocket further and further at constant rate. Then what about Universe's speed limit?
