How do pandas survive in the wild?

From the perspective of a photon, does time stand still?
If so, how does it interact with anything at all without the rate of change (time)?
Or how do we experience the CMB redshifted from long time ago. For the photon itself no time has passed, but one of its characteristic properties, the wavelength has changed for us...

I'm very confused

why did he die in a duel? why was he so concerned with politics (and with a meme political ideology that is mouthbreather tier at that)

How do I cope with being born with a small brain volume? My whole family headmogs me and I get existential anxiety every time I study anything because my thoughts lead back to being an incompetent brainlet.

Early humans are thought to have wandered around without any clothing and spoke in languages that lacked any syntax, orating one-liners to get information across. Obviously, humans didn't suddenly develop modern levels of intelligence.

This Wikipedia article basically goes over how advances in human intelligence were consequences of hardships faced by humans, giving plenty of credence to the idea that Eurasians are more intelligent than black Africans due to the fact that life was simply more difficult in Eurasia. (North Africans are the descendants of Eurasians.)

I still can't think of a clever paragraph or two to spam whenever I see someone online saying racial differences in intelligence don't exist that makes it look ridiculous to even question the non-existence of racial differences in intelligence. Ryan Faulk has produced some great videos, but those are long videos and filled with to the brim autism. Also, plenty of normies aren't going to want to watch his videos when the name Alt Hype sounds very similar to alt right, and a lot of the symbols he uses are from politically fringe elements, thus making him look like a nut from the eyes of people who are familiar with those symbols.

Anyone want to discuss mycology? Had some neat finds recently, p. antillarum, p. cinctulus, p. cyanenscens. Would love to develop a niche knowledge about panaeolus. Also microscope buyers guide for retard?

How do radio waves from towers actually travel? Is it like a spherical pulse?

So I need to find this out but can't seem to find a simple answer anywhere on the internet. I am planning on purchasing a geiger counter as preparation just in case WW3 actually happens. The display of the one I'm counting on purchasing reads in msv. I'm trying to find out what reading, very roughly, is high enough to warrant needing to leave a particular area? Basically, what is the minimum reading on a geiger counter in msv where one should leave, or start to use a respirator? A simple rough numerical value would be welcome. Every article I've tried has just been bullshit about how "muh you can't trust geiger counters, radiation is complicated", fucking patronising nerds can't give a simple answer.
