For future reference: PF does not allow personal theories. PF supports established, peer-reviewed standard model science. That does not...

There are many events that take place that are no where near that fast. Also, to make you perfectly immune to any changes or effects if...

I should probably write the relevant formula involving hyperbolic-trigonometry. ##\beta=(v/c)=\tanh\theta ## so...

No. Light does not experience time. There is no valid frame of reference for a photon. This is a direct result of the postulates of...

I am just trying to say things are possible. If you go back in time and make changes that do not affect you than you are safe. If you...

No. There is no meeting a copy of you that would be your younger self. The traveler is moving back & forth along the timeline.

Time travel is logically possible. IF you moved faster than light or even a little less with time-dilation taking effect you live on...

"Proper time" does not exist for the photon. However, there must be a sense of causality, The Emission-event occurs before the...

No. The time experienced along a null path is not zero, rather it is not defined. No. Or, more precisely, you need to define whether...

I don't think there's any simple way to describe how a photon moves. It is not at all like a regular missile. The information that is...

For example: If you send a light pulse from Earth to Alpha Centauri, then the spacetime-interval between the emition-event on Earth and...

Not a great question but I heard someone say that time does not move for a photon. T=0. So therefore both its Emission &Absorption are...

The problem comes when you try to describe that scenario. The devil is in the details. How would you know if time had stopped on a...

I can measure what is going on from Earth...

My point is not about clocks but time itself.🫡
