Comment on If you think about how big the universe is, the fact that we can manipulate energy on such a small scale, like raising the temperature of something by one degree is absolutely insane

My mistake with the wording, I will say though infrared light raspberry pi are no, still would not be enough for that. You need serious lab equipment. Like advanced cooling methods to achieve this sort of thing. That’s why I chose this range. With your method I could see possibly being able to do a percentage of a degree in keeping it stable with no outside forces, but accuracy within a millionth I think is a stretch

Alright so you want to cool something down to an absolute temperature that is in the micro kelvin? Yeah, that’s is going to be hard.

But you could just go from 300.000001K to 300.000002K for example, no super cooling required. So far your wording only implied a change, no absolute values. Otherwise it would also be pretty hard to get to 1K for your one degree example.

Yeah ok, if want to keep an object at an exact temperature with that precision, you’ll need some additional stuff. But I don’t think you’ll need a top tier lab for that. A vacuum chamber with the test object, an array of infrared lasers suspended inside and a bit of electronics in a temperature controlled room should give some good results.

A millionth isn’t that small though, but it will get impractical if you go even smaller.
