Some Random questions (plz help) If its ok, I have 5 random questions Id like answered. I’ve thought about these for some time. hope its ok. 1) I read that 10-33 seconds after the Big Bang, the Universe went from the size of 100's of billionths of an atom to 100million LY across within 10-32seconds? Is this remotely true? 2) Were does all the light go when you turn off the light in a closed room? I heard it recoils to a different wavelength? Would it still be bouncing all around the room, & we just can’t see it? 3) I read to probe into the smallest scales of on the universe, a particle accelerator the size of the galaxy would be needed. Why is this? 4) With the cat in the box experiment, would the very objects in the box (cat) interfere with the experiment causing the wave function of the cats life to collapse straight away? 5) Is there anyway to make a home made version of the double slit expeirment? I would love to show some ppl. But wouldn't no were to begin. Please excuse my lack of knowledge. Any advice is appreciated. Thank you.
