Reply to How does the sun's gravity hold planets like Saturn, Uranus, and Neptune in orbit without pulling in Mercury, Venus, and Earth in and totally crushing them? by Tmettler5
When something like a planet is orbiting a massive object in a vacuum, the planet is moving sideways at the same time as falling into the massive object, so it keeps missing. The smaller inner planets are moving sideways much faster than the outer planets, so they continue to miss the sun.
That sideways motion combined with the gravitational pull towards the sun results in an elliptical orbit.

Growth = death of quality for social media. Happens to everything. Every subreddit that gets big gets shit unless it is heavily moderated.
Most people are just stupid and annoying. Sorry but that's the truth, and if you worked with the general public you would agree.
I believe Churchill had something to say about the best argument against democracy being a 5 minute conversation with a typical voter.

I think it's a feature to not have that kind of person on the network.
Average intelligence of the user base goes up, and there are fewer trolls.
It's not hard to do a bit of reading and learning before engaging with the platform. Well, not hard for thoughtful, intelligent people.

Reply to Why does temperature determine the sex of certain egg laying animals like crocodiles? by insink2300
Temperature affects the rate of chemical reactions.
Complex biological pathways result in more or less of particular hormones being produced at different temperatures. This is useful in cold-blooded organisms, because if the chemistry of some biological function tends to shut down beyond a particular temperature threshold, the organism can incorporate other biological systems that kick in to replace it.
The advantage of having offspring's sex affected in such a way is open to discussion.
