So how do they know that the "background" microwaves are from the edge of the universe? I thought that the primordial microwaves are scattered throughout the universe, so what we see when we look in some direction is the sum of all the background microwaves coming from that direction.
If we're actually seeing the edge, doesn't that shoot down the idea that the universe doesn't actually have an edge, and everywhere appears to be at the "center" of the universe? How was this idea disproved? I seem to have missed the discovery of an actual edge, somehow.
The cmb is simply the first light that was able to freely travel through space. There is no actual 'edge' but there is always the apparent virtual edge beyond which you cannot see. It's easiest to think of it as space being infinite in size but finite in age. Light needs to travel to your eye to see so the farthest you can see is simply the age of the universe x the speed of light. As the universe cooled right after the Big Bang, initially light could not directly pass through all the hot plasma, only after it cooled and became transparent to visible light did light spread out in significant amounts. The heavily red shifted version of this light is the cmb we see today. Your own two eyes see a slightly different virtual 'edge' as every point in the universe looks as if it is the center.
It took about 380k years for the universe to become transparent to light neutrinos pass through ionized material easily and the surface of last scattering is nearly as old as the Big Bang. It's a very old concept but has been researched lately as each kind of neutrino would have a slightly different background. The article is just random click bait there is nothing new or interesting about it really.
Okay, as long as we're in conspiracy theory land, I'll bite.
What route do you expect the 1% to take to eliminating the surplus population? Will they do it Adolph HItler style, with purpose built facilities where the 99% will be rounded up and exterminated? Will they do it Joseph Stalin style and simply deprive the vast population of food and other needed necessities?
It seems more probable that in a future dystopia, they might claim the best resources for themselves, set up their own communities with heavily armed guards, and live the good life while the masses eat one another to survive.
Woah woah woah. We are already talking about automated semi trailers why not go to the next logical step and assume a self replicating robot drone army? Why starve or kill the old fashion way when you can live on paradise island while the rest of the world burns terminator style in preparation for the construction robots to turn it into paradise? At the very least you could force them to do whatever you wanted. At no point in history could the 1% actually do away with the rest of the humans. Now with tech not only is this possible it may become preferable as they see it.
