If its a optical image satellite, it probably doesnt take much to burn on the camera if it’s shutter is open.

I imagine the precision needed for that is lacking in a solar mirror motor.

Small satellite that’s at least 100km away

Yes but that’s socialist.

And goes against my donors paycheck.

/s but many people in charge are willfully ignorant that society can be built in a way that doesn’t rely on cars.

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.

That seems around what I’d expect the measurement error to be anyway

I’ve only rented an ev, but only about half the time they have successfully taken a cc. Either they were broken, or it was just missing.

A lot of them have apps, which is very annoying as a renter, but if you own the car it should be less of an issue.

Eventually yes, but I personally think that recycling solar panels and so on could slow collapse much more than the author suggests.

Also batteries, lithium is expensive so a lot of companies are trying to come up with cheaper, but also more sustainable alternatives. And they already have with lithium iron phosphate that requires less lithium. And as prices for a substance rise, so will the desire for alternatives and recycling.

Adding sugar in low amounts to food will makw is spoil faster. Sugar is only a preservative at high sugar concentrations to prevent bacterial growth.

Notably missing from this lists are acids: lemon juice, vinegar, citric acid which will lower ph and slow bacterial growth.
