PhysicsOverflow is a next-generation academic platform for physicists and astronomers, including a community peer review system and a postgraduate-level discussion forum analogous to MathOverflow.

Welcome to PhysicsOverflow! PhysicsOverflow is an open platform for community peer review and graduate-level Physics discussion.

  Light speed and travel. Did i discovered something new?

+ 0 like - 2 dislike

Theoretically if an object reaches the speed of light, from our perspective , the object is frozen in time. So does that mean that from the photons perspective,it took him 0 time to travel from point A to point B? And does that imply that a photon traveling in a straight line from point A to point B is in all places at the same time and the fact that light moves in space is an ilusion caused by the fact that we travel through time? I have a major in computer science so excuse me if this question seems trivial.

Closed as per community consensus as the post is not graduate-level

It is completely wrong. If an object moves with some velocity $v$ from our perspective (reference frame (RF)), it moves with this velocity and it is not frozen in time. If it is free, it moves according to the law: $x(t)=x(0)+v\cdot t$. You see, it is not frozen at all. If it radiates, its frequencies are Doppler shifted in our RF. Please do not ask here such questions, this forum is not for undergraduate physics.
 

This is probably suitable for some other forums, like physicsforums.com.
