If dark matter is invisible and doesn't interact with light, could it actually just be the universe forgetting to turn the lights on in certain areas?

I want to end this annoying myth once and for all that time passage is different in further space due to gravitational pull. Time does not exist, it is a measurement of relative positions of objects in a gravitaitonal cycle that we organize according to and have accepted the concept as a...

If the results of The Double Slit Experiment sound weird, there is yet another experiment that demonstrates quantum mechanics effects, that trumps everything else. As far as proofs of quantum mechanics goes, the 3 polariser experiment may be considered to be the ace in the hole...

I have a question to ask people that know or understand a lot about the universe and mathematics. So the question is this: "If the reference point of light doesn't experience time due to time dilation at higher speeds, does this mean that time stops? If time would stop would this mean that...

Can it not be so that the dark matter we're looking for perhaps not even exist and the bindimg/repelling force might be space itself, since black holes collide and gravitational waves are generated, and the speed at which those waves travel can't surpass that of light, so it may be that those...

This is an interesting question, namely can a photon travel forever if nothing gets in its way? More importantly how does it travel these enormous distances. All our considerable experience with light and electromagnetic radiation goes to show that light follows the inverse square law while...
