Is it possible that time does not completely halt when traveling at C(a photon)? C is 299 792 458m per second. If you turn those meters into time, u get 9.506 years per meters traveled. So when you have traveled in 1 sec, 2 851 800 000 years would have passed.
Does not that explain the redshift effect we see when we see so far. Is not the doppler effect, not according to Einsteins relativity? A not expanding universe
Will not photons over large distances loose abit of energy because of the universial gravitational potensial? The work, preformed by the light to overcome the gravity over so waste distances, so the frequenzy drops down to red, theras redshift effect?
If we have two nutrients stars orbiting each other, they produce GW. But can we find solar systems and planets if we get better and more accurate GW detectors? Like lasers in space with great distances.
I'm quite new to physics and getting a grasp on gravity and objects falling. But I can't get my head around this: If I have a pendulum thats 0,5m long with 1kg at the endthat just hangs there. And if I hit it and it gets an angle close to 90 degrees or close to 0,5m before it falls back down. whats the force, energy or work needed to make this happen? What equations is needed?
