That isn’t really observable to our naked eye though, that’s Doppler shift and is the same thing that makes a sound change pit h if it’s coming towards you or away from you (think of a siren as a cop car passes you). The Doppler shift, or redshift of stars and other celestial objects is how the expansion of the universe can be observed and measured.

I won’t order them any way but animal style. They’re just not as good as they could be, IMO.

Sure, but if it lessens the impact on the climate from air travel and vehicles, then it’s a good thing. Especially if they can become reliable and convenient enough that people don’t need to have their own vehicles to drive everywhere.

They’re faster and more comfortable than traditional rail. They could help to reduce air and vehicle travel

I don’t think it was a mistake, it brought next gen gaming to people that can’t afford, or don’t need the highest spec machines. I have a series S so I can play Xbox games with my son, I also have a gaming PC and steam deck. The price of the S allowed me to justify buying this, but I wasn’t about to drop the dough on an X just to play a few Xbox games

They can be found cheap as shit. I got a great t480 for less than $150 and another $50 I upgraded my RAM and battery. It’s a really nice laptop and only cost me a couple hundred.
