He talked about electric cars. I don't know anything about cars, so when people said he was a genius I figured he must be a genius.

Then he talked about rockets. I don't know anything about rockets, so when people said he was a genius I figured he must be a genius.

Now he talks about software. I happen to know a lot about software & Elon Musk is saying the stupidest shit I've ever heard anyone say, so when people say he's a genius I figure I should stay the hell away from his cars and rockets.

Light needs about 8 min 20 sec to reach us from the Sun which is 147 million km away.

Let's say this distance corresponds to one sheet of toilet paper. Then the distance from Sun to Neptune is about 30 sheets. Voyager 2, the 2nd farthest travelling human artefact, is about 100 sheets (1/4 of a 400 sheet roll) away.

How far away is the closest star, Proxima Centauri? About 670 toilet paper rolls. And the center of our own Milky Way? 4 million toilet paper rolls.

People arriving on Mastodon griping about how it's not enough like Twitter remind me of Californians who moved to New Mexico (when I lived there) who complained that it wasn't enough like California. They annoyed us greatly.

You're in a new place. Chill out and take time to learn what makes it special.
