[…] only a few hundred of them have been detected in the local universe

Why haven’t they checked other universes?

What kind of algorithms are those trains running?!

Make sure you check out the simulator webpage for some sweet old school design and a lot of neat pictures! I love a good simulation.

Astronomy is constantly discovering never-befor observed phenomenon. The idea that you can simulate realistic images of anything requires you to have sufficient knowledge of reality, and astronomy keeps showing us that we don’t have that.

The only way I can see this being helpful is to train algorithms for what is already known and can be safely filtered out, making it easier to detect new observations

And slowly, society began to awaken to the reality that theirs was a civilization ruled by Mammon, not men.

It’s starstink muskings up the sky.

I get the actual issue, but that title sounds hilariously boomer.

I still think they should build out a lunar crater radio telescope out there on the dark side of the moon. The radio silence and scale would be impossible to get any other way.

scale

That’s an interesting thought I hadn’t considered. The Webb is about as quiet as we’re going to get anywhere near our orbit, but a lunar compound could very easily be much larger, and would be a great deal easier to service/upgrade.

The dark side of the moon is shielded from the planet’s radio by the whole moon. So it’s a pretty attractive place to set up.

Plus, several candidate craters have favorable geometry for a massive radio telescope.

It truly is one of my favorite proposals.

That’s the far side.

Yes the far side of the moon is colloquially (and incorrectly) called the dark side of the moon. Thanks for the correction.

Yeah, we need fewer satellites really.

As for the rest, that’s not easily solved.
