WHY CAN ANY PARTICLE CROSS THE SPEED OF LIGHT?

WHY SHOULD THE OBJECT BECOME SLOW?

WHAT IS THE IMMEDIATE CAUSE OF TIME DILATION?

Expert Answer:

1) Speed of light is the limit of speed up to which any object can travel. There is a concpet in relativity which connects mass and speed of a particle. According to the theory any object travelling at speed of light will have infinite mass which is not possible. Also according to Einstein's mass energy equivalence (E = mc2), infinite mass will have infinite energy associated with it which is again not possible. Hence, any particle cannot cross the speed of light.
2) We did not understand this question. Kindly provide additional details for the question.
3) The immediate cause of time dilation will be that every event will appear to take place at a much slower rate than it actually occurs.
