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...

Like.
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...

spacecadet2563 replied to the thread Undergrad Photons & Time: t=0 What?.I can measure what is going on from Earth...

spacecadet2563 replied to the thread Undergrad Photons & Time: t=0 What?.My point is not about clocks but time itself.🫡

Haha.
That would be a commute of 30 minutes! Less than it takes me on a busy Monday. -

For example: The distance from Earth to Alpha Centauri is 4.367 LY. If you travel with 99.99999999 % light speed (relative to Earth) to...

spacecadet2563 posted the thread Undergrad Einstein's time formula in Special and General Relativity.In his formula if V were 2C than that fraction reduces to 2 and the result is a √-1 in the denominator. How is that to be interpreted in...

spacecadet2563 replied to the thread Undergrad Photons & Time: t=0 What?.Thanks for all responses...

Yes, according to the math, the clock rate approaches zero, when its speed approaches c. So if you take the limit, it is 0 at c. What...

Be highly skeptical of any source that you read which discusses what happens on a ship that reaches ##c##. It might be a great science...

spacecadet2563 replied to the thread Undergrad Photons & Time: t=0 What?.But for light it goes or is at zero? Does the math say this? Why would clocks magically stop? If that ship was 99.99999999 % light speed...

spacecadet2563 posted the thread Undergrad Photons & Time: t=0 What? in Special and General Relativity.As you move closer to the speed of light time begins to slow down for those looking from Earth. But time on the ship is normal for them...
