Our universe (the "Big Bang universe") is just a tiny spec of dust in an infinite universe (some call it multiverse but I dislike the term).

Basically when entropy gets too high in an area, AKA "the heat death" of the universe, a Big Bang spontaneously happens and seeds stars.

Our challenge to survive, would be to manage to switch universes before that happens.

The oldest human who is known in the modern age was an accountant from 5000 years ago. He was basically a nobody. A cog in the Sumerian trading system. That he is remembered while the great leaders, warriors, and artists of the time are forgotten shows just how capricious "fame" can be.
The next oldest are the slave owner, Gal-Sal, and his two slaves, a man named En-pap X and a woman named Sukkalgir.

From what I've seen, it mostly just appears to be "muh huwhite race" types (not necessarily white people, but really just anyone who categorizes race in such a way) coping that humanity didn't spawn from their preffered area. Am I correct or is there anything actually backing up their claims?

Science and technology people are terrified of, to the point that they reject it and often ban its research:
>making people immune to deadly diseases
>genetically improving humans
>genetically improving crops
>atomic energy

Science and technology society allows, and does nothing to stop:
>making everything in society a piece of adware
>bot-driven mind-control
>attempting to build a machine god (probably to serve ads better)

People would legitimately rather the future be dysgenic diseased people addicted to Kraft ads and chinese internet propaganda, than allow someone to improve the world in any way? Why? What good things can you even research in current year without some ethics jannie blowing a fuse?

Retard. You solve it by stopping whatever you're doing to strain your central nervous system. Too much caffeine, not enough sleep, lack of certain nutrients, whatever else might be doing it. You don't need meds to treat it.

When I was younger I developed a distressing idiopathic eye problem that was ultimately temporary but caused me to obsessively pay attention to entoptic phenomena in general.

I obviously can't experience other visual snow-haver's subjective experiences but I developed visual snow during the episode I described above (which lasted a couple years).

While I definitely did have some sort of eye issue at some point, a lot of my follow-on issues including the visual snow ended up just being anxiety-induced body OCD. Your visual system is actually quite a noisy sensor, especially in the dark. Your brain typically filters out this noise and only presents you with the semantically meaningful visual content. But it's possible to hyperfixate on the spurious components of that signal and actually break that mechanism by paying too much attention to it. It's similar to how listening to your own tinnitus makes it worse.

You need to remove stressors from your life, stop using drugs, get on a healthy sleep schedule, and just accept that experiencing sensor noise in your visual and auditory systems is normal and not necessarily pathological. Ignore it, make peace with it, stop paying attention to entoptic phenomena, and enjoy your brief time on this earth, noisy as it may be.

You can break down the lignin in wood while leaving cellulose intact. This can be done by either inoculating wood with a white rot fungus like oyster mushrooms that will digest the lignin for you or by fermenting wood with brewer’s yeast and sugar water at about 25 C for a few weeks to create flake soil. This is how beetle breeders prepare wood for beetle larvae rather than having to go out into the woods and find rotting wood at the correct stage of decomposition to collect

Interesting that it's dependent on fungus. Before that enzyme evolved, lignin would never decay.

Interesting question for biologists. Hypothetically there is a couple, both have all genes for blonde hair, but the mother is red head with two paires of ginger mc1r, and the man has no ginger genes. What hair colour would their children have? Will all of them be blonde? Or there is possibility of red haired kids? What are the odds?

>Some intentionally missing the point of the question eg. Water will get stuck at the bottom

Funnily enough, simply typing "which will empty first" into Google's AI, will yield the correct answer. But you don't need to understand water pressure to get the correct answer. It's basic common sense, that the white man, and to some extent, Asians, are supposed to have, but Indians and social media retards lack.
