Welcome to /c/tumblr, a place for all your tumblr screenshots and news.
Our Rules:
-
Keep it civil. We're all people here. Be respectful to one another.
-
No sexism, racism, homophobia, transphobia or any other flavor of bigotry. I should not need to explain this one.
-
Must be tumblr related. This one is kind of a given.
-
Try not to repost anything posted within the past month. Beyond that, go for it. Not everyone is on every site all the time.
-
No unnecessary negativity. Just because you don't like a thing doesn't mean that you need to spend the entire comment section complaining about said thing. Just downvote and move on.
Sister Communities:
-
/c/TenForward@lemmy.world - Star Trek chat, memes and shitposts

Helium is portrayed as second most abundant element in the universe. Not scarce at all. Our ability to collect and make use of it, that's scarce.
A squirrel would probably need about 100 balloons.
Second most abundant doesn’t really convey how much more abundant it is compared to other elements.
About 75% of all the mass in the universe is hydrogen, about 23% is helium, 1% oxygen, and that leaves just 1% for everything else.
Next useless project: design a small rigid airship for roadkill disposal.
