PeroK reacted to spacecadet2563's post in the thread High School Time travel without paradox with
Sad.
Time travel is logically possible. IF you moved faster than light or even a little less with time-dilation taking effect you live on... -
PeroK replied to the thread Graduate Horizontal component of the electric field of an infinite uniformly charged plane.If you have have linear wires, then the linear charge density must tend to zero, as the number of wires increases. You end up with... -
PeroK replied to the thread Graduate Horizontal component of the electric field of an infinite uniformly charged plane.An infinite uniformly charged plate is a physically impossible construction in classical electromagnetism. A charged particle has... -
PeroK replied to the thread Undergrad Photons & Time: t=0 What?.Time is what a clock measures. In this context, at least. -
PeroK replied to the thread Graduate Horizontal component of the electric field of an infinite uniformly charged plane.If I have time, I'll look at the details of what you've done. In general, if you have two limits, then the order can make a difference... -
PeroK replied to the thread Undergrad Photons & Time: t=0 What?.For example, the Newtonian gravitational force is given by ##F = \frac{Gm_1m_2}{r^2}##. In theory, two point particles can be... -
PeroK replied to the thread Undergrad Photons & Time: t=0 What?.The limit is not part of the theory of special relativity. -
PeroK reacted to renormalize's post in the thread Graduate Can a causal or time-like structure emerge without assuming a metric? with
Like.
Can you illustrate your distinction between a law and a relation using examples from physics? -
PeroK replied to the thread Undergrad Photons & Time: t=0 What?.A clock can't travel at the speed of light. All motion between you and a clock is relative. If the clock is moving at 99% of the speed... -
PeroK replied to the thread Introduction.Check the rules. We can't discuss your personal speculations here. -

Take a look at https://en.wikipedia.org/wiki/Causal_sets: "The causal sets program is an approach to quantum gravity. Its founding... -
