I saw him in my mates house the other day kissing a mirror? He said he is the only person he can kiss in the mirror or something.

I thought the torus shape was the accepted theory? Guess I haven’t been keeping up on this.

Near the bottom of the article they mention that if the universe wasn’t flat, we would see multiple copies of the universe in the sky. I’m not sure that is exactly true? Given the speed at which the universe is expanding, especially during the early period after the big bang, it seems reasonable that the light from most stars wouldn’t have had a chance to loop back around yet. Even the light from the earliest stars is just reaching us, so I don’t know why they think it would have had time to loop back around multiple times, unless there’s something I’m missing?

And nothing in the article really touched on the “holes” mentioned in the title. Are they referring to the center of a torus, which isn’t really a hole that we could observe? I don’t get it.

What a great article! Very informative and easy to read.

The telescope sounds cool too! An 8.5 meter mirror?! And it’s designed to be able to recoat it over time!

1. ornithopters are already real
2. the machine in the article image is not one.

Unrelated, but I just wanted to say that rotating Mars icon for the channel looks pretty slick.
