Can't sleep, so thinking of physics. Yes, I'm weird.
Universe is flat because Relativity works. If universe weren't flat, relativity would not work. Relativity is based on the angles of a triangle adding up to exactly 180 degrees, you know. QED.
My model of how gravity, spacetime, and velocity work (see earlier posts) posits sine/cosine based laws of motion, energy, and perceived time. Redshift data proves this. Why does universal expansion appear to accelerate? Because the slopes of sin (x) and sin^2 (x) change. There is no actual acceleration or deceleration. It just appears that way. Because geometry says so.
The difference in energy levels (red shift) between two points is determined by the slopes of the individual energy curves. Everything has a energy-differential sphere around it. (Lowest energy in direction of motion, highest directly opposite, and neutral at 90 degrees to motion.) This is what causes motion, perceived time, and energy gain/loss (blue/red shift). The difference in slopes of any two objects determines this. This is also where you get sin^2 (x) from - you multiply the two together to find the total.
Or maybe I'm just stupid tired and getting everything wrong. That might very well be the case.
(Re-try...) Well, *I* don't know. (re: Relativity & 180 degree triangle and flatness of space/universe). Anything you can point me at to explain such (I am *relatively* new here). Thanks.
ReplyDeleteRelativity is a big subject, and wrapped up in a lot of other fields. But a good place to start is the book "How to teach relativity to your dog", by Chad Orzel. He also has "How to teach quantum physics to your dog".
DeleteMost of what you can find on the internet about relativity is wrong, or partial truths. This is because most people, even most physicists, don;t actually understand it. They just, at best, learn how to do the math to plug and chug.
Check out the Minute Physics video series on Relativity. He made a machine to show how the geometry works. It's pretty cool.
