According to what I have learned, in an autonomous system the force acting on the particle does not depend on time. In the simplest case we can suppose that force depends only on position coordinate $q$. However, I can't understand why phase trajectory can't cut itself in such a situation (like...
My understanding of general relativity is that gravitation is equivalent to spacetime curvature and is proportional to localized mass. Traditionally, we conceptualize that massive things attract each other by bending spacetime. Could some mechanism in the early Universe have warped spacetime and ...
I have noticed the "unclear what you're asking" close reason misused multiple times (if asked, I can provide links, but I can think of many). However, there was one recent case that made me write this post. Increasing The Momentum Of A Photon has four close votes saying the question is unclear. T...

Is it possible to acquire enough energy or speed to "break" the 3rd dimension and travel a fourth dimensional plane. If you could do that and travel to a otherwise, impossible to access area in/outside our 3 dimensional world?
