Not quite, the true invariant quantity is the magnitude of the spacetime 4 vector, which depends on rest mass.

It actually goes further than that. In spacetime you’re always going the same speed, the more in space, less in time.

At least from the special relativity perspective.

They will be safe to eat indefinitely, but may not be palatable, depending on how it’s stored.

Sounds like intels optane drives

The cost to benefit looks way better if you think long term. Especially with climate change on the horizon to compete with planes but emission free.

One of the major problems for upgrading lines is straitening the route, and people fight the emniment domain way harder than they do for roads.

I’m not disagreeing with that, but high speed rail from Boston to Miami would be extremely practical. Efficient, fast, convient travel along that corridor reducing dependence on cars for city to city travel. And the area has both the demand and density to support such projects.

And while its impractical now, if it was built to cheapen regional travel in the region it could grow to high use spurning economic development.

I’d love to take a train at a reasonable pace from near to DC to my family in Pittsburgh, or to visit New York.

I might even enjoy a cross country trek to the rockies for skiing on a train, but it’s never going to be an option.

East coast united states has similar population density to most of europe.

It’s just out west we have a lot of empty land.

The price fixing is only for steam keys which is completely reasonable.

The average car age is 12.5 years, so many of them are likely approaching 20

Yeah and that’s why I’m not advocating for 100 year cars.

I’d be pretty happy with 20 years to, but 10 just feels like planned obsolescence.

I also messed around with the math very loosly, and only accounting for crashes that total a car, they could be expected to go 20 years or more on average.

And that’s now with all the terrible driving that happens, especially at night. With slight deacrease in accident frequncy that number can increase a lot.

So maybe 30 is a bit much for now, but I’d still like an ev that would claim to last 20 yeara.

So far most ev batteries do much better than cell phones, as long as they have cooling.

But you still have it backwards.

We could very easily design and build a car that lasts 30 years. But we don’t, because manufacturers don’t want them to last that long.

Evs don’t have transmissions, or complicated engines, and the wear on brakes is much less with regenerative braking.

Other things like air conditioning and interior coverings could be easily servicable

Why should the life of an ev by limited by its battery?

Do really need need 4?

If you cant get by on 2, you might have less power, but you can get better efficiency. With better efficiency you can have a smaller battery for the same range and reduce some of your increased cost that way.

If you’re gonna go through all this trouble, why not put motors directly into the wheels? Then you can bypass the drivetrain all together and directly power the wheels.

Anybody got a non paywalled version?

If you’re barely scraping by, having less money can significantly affect quality of life, or at least percieved quality of life.

Prey and outer wilds are games especially enjoyed blind with no prior knowledge.

I made a switch to linux recently and some of my paid software works there too.

Most steam games, Matlab. Wine and proton make it possible to run many Windows applications

I’m not on beehaw, but I ran into similar problem when I joined lemmy.

My solution was to filter communities and users where I felt I was getting apammed with content at a frequency I didn’t enjoy.

You might get some milage out if that approach.

Nvidia shield is the best,

Roku devices are pretty good for less money
