It's the dunk tank.

This is where you come to post big-brained hot takes by chuds, libs, or even fellow leftists, and tear them to itty-bitty pieces with precision dunkstrikes.

Rule 1: All posts must include links to the subject matter, and no identifying information should be redacted.

Rule 2: If your source is a reactionary website, please use archive.is instead of linking directly.

Rule 3: No sectarianism.

Rule 4: TERF/SWERFs Not Welcome

Rule 5: No ableism of any kind (that includes stuff like libt*rd)

Rule 6: Do not post fellow hexbears.

Rule 7: Do not individually target other instances' admins or moderators.

Rule 8: The subject of a post cannot be low hanging fruit, that is comments/posts made by a private person that have low amount of upvotes/likes/views. Comments/Posts made on other instances that are accessible from hexbear are an exception to this.

Rule 9: if you post ironic rage bait im going to make a personal visit to your house to make sure you never make this mistake again

But that means that every atom besides hydrogen, at some point, has undergone this process.

If we disregard the fact that by mass, most of the universe is comprised of gas clouds (since they are kinda in the process of becoming stars) we are left with stars and other bodies such as planets and asteroids and moons. If we take our solar system as the example, over 99% of the mass therein is contained within the sun.

The conclusion from this is that, although the overall composition of the sun isn't rapidly turning into helium or anything, there's about 600 million tons of hydrogen in the sun undergoing fusion every second, producing nearly that same weight of helium.

Is that significant in the grand scheme of things when discussing the universe? Absolutely not. But it's still an absolute fuckload of hydrogen changing into helium every moment across the span of the 4.6 billion years of existence of the sun.

I think as a thought experiment in the immense amounts of helium being produced this is worthwhile to consider. If you would argue that I'm defining away the problem or that I've shifted the goalposts so far as to be discussing something only tangentially related to the first point, I wouldn't disagree with you on that. But for the average person, the quantities of hydrogen becoming helium in our sun alone is absolutely mind-boggling.

as it relates to the point about binary sex, i guess it's not really a good comparison. or maybe it is. all zygotes begin as females but may switch later, much like hydrogen fusing into helium. so then it is a good analogy. i don't understand why it would be hard to accept that analogy the more i think about it. we are mostly binary, but with a small degree of spectrum. i don't understand how accepting that fact defeats a movement.
