Hah yeah: "Duck and cover!" :woot: -

Like.
True. False. The proper phrasing in daily language is "the observer never sees light signals from the horizon formation". But it is a... -
What you are really measuring, if anything, is whether a (rigid) object retains the same proper length when rotated in a gravitational...

ShadowKraz reacted to PeroK's post in the thread I Can this experiment break Lorentz symmetry? with Like.
That's what the Michelson-Morley experiment did. If there were a universal rest frame (in which Maxwell's laws held), then the speed of...

Here's an experiment to show that, once you remove air resistance, all objects have the same acceleration under the Earth's gravity...

That is the way that gravity works. The force of gravity is proportional to the mass: ##F=mg##. And Newton’s 2nd law is: ##F=ma##...

Yours is a common dilemma. If you cannot or will not learn the required mathematics to study modern physics as an undergraduate student...
