  • Disclaimer: I could be wrong or not up to date, but this is my current understanding.

    On the small scale, forces like electromagnetism and gravity pull things together much much faster than the rate of cosmological expansion. That’s why “we” don’t expand, and neither does our frame of reference. There’s a potential end to the universe where the rate of cosmological expansion (which increases over time) finally exceeds gravity and electromagnetism and eventually even the strong force, causing everything to fly apart forever.

    Light waves propagate through spacetime itself, and basically it ends up being that there’s nothing pulling it back from expanding as the space it travels expands.

    I’d honestly love to just plug in every night instead of having to spend time getting gas every week. Sure it’s only a few minutes, but that’s probably a few hours of my life every year. Getting an electric vehicle and renting cars for road trips would honestly make much more sense for me.

    Unfortunately, it looks like it’d be financially irresponsible for me to buy an electric car right now while I still have a perfectly functional ICE car.

    I make a 9-10 hour drive to see my family multiple times a year. I normally stop twice to get gas and use the bathroom, and that’s it. Sounds like you’d be adding most of an hour to my travel time each way. I’ve tried stopping longer and grabbing food, it’s not worth it for me.

    With that said, I drive 25-40 miles a day the other 360+ days of the year, so it’d really make much more sense for me to have a short range EV and rent something for travel when I have too much luggage to fly.
