Yeah, it was a constant refrain.

Well, you and Leo both mentioned forms of transportation, and I have one that I don't think is possible right now, but I would like to see it happen.

It is a hovering subway, like a subway that doesn't hit tracks.

Okay.

It hovers above tracks so that it doesn't make a screeching noise.

And that it's like a little faster and just a little more agile.

Like a hovering subway?

Okay, well then.

Oh, in China?

Wait, so they hover literally, like how much do they hover?

Right.

Okay, so I just want the thing that already exists.

All right, well, listen, I have another question.

This one's like very scientifically advanced, I think.

From Martin.

Martin in Denmark says, I have a question about- In Denmark, I love it.

Yeah, about red shifting.

What makes the light red shift when traveling great distances?

And do we know that we're directing all the red shifted light or is our current equipment not good enough to detect light from, for example, 50 to 100 billion light years away?

Oh, right, because we're going to the other end.
