    High School Light & Time

    Its all really one event not two would be a safe assumption.

    Never declaring anything wrong.

    High School Time travel without paradox

    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 you were traveling faster than light than obviously not an issue. Quick answer.

    High School Time travel without paradox

    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 did your parents in there is the idea of suicide. Physics would allow this. Just an example: if I drop a ball it takes time to hit the ground. Cause &effect. If...

    High School Time travel without paradox

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

    High School Time travel without paradox

    Time travel is logically possible. IF you moved faster than light or even a little less with time-dilation taking effect you live on another timeline. It is not synchronized with those on Earth.Therefore events that happen on Earth like killing your parents before birth cannot reach you. True?🤔

    High School Light & Time

    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 simultaneous events. I say no. If both of these events are supposed to be considered different events than there would need to be a time interval between them...

    Undergrad Photons & Time: t=0 What?

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

    Undergrad Photons & Time: t=0 What?

    My point is not about clocks but time itself.🫡

    Undergrad Einstein's time formula

    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 a time formula?🤔

    Thanks for all responses...

    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 time would still be normal. But that last decimal point bang...the clocks stop.

    Undergrad Photons & Time: t=0 What?

    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. Go faster and slows down even more. Same thing. Time is normal. But I read when it reaches speed c the time on the ship goes to zero. I say wrong. Its still...
