21k and 69k are so cold that time would dialate significantly at those temps
This has me confused.
Temperature can be used to refer to how fast the atoms are jiggling (kinetic or phonon temperature) or to how messy, disordered (opposite of ordered) a system is.
Time dilation is a relativistic effect where time appears to go slower when you are looking at something that has a very high speed (near light speed) compared to you (relative velocity). Can also happen with mass because gravity is acceleration, thus related to velocity.
If the atoms are jiggling slower, relative velocities only shrink, so you’d expect to see less relativistic effect. I am not aware of any relativistic effects due to thermal motion in normal conditions (room temp, atmospheric pressure), so I don’t know how they’d appear when relative velocities only decrease.
I am really interested where you got this temperature - time dilation link from. Can’t seem to crack it.
I was taught that any energy exerts stress on space-time and because of that removing energy, lowering temperture, causes dialations.
Where were you taught this? It’s pretty much incorrect.
It is true that particles at higher temperatures have higher kinetic energies. But their velocities are so far away from light speed (usually) that relativistic effects like time dilation are entirely irrelevant.
For reference, the surface of Pluto is about 40K. Some of the other dwarf planets a little further out are in the 21K range. Liquid hydrogen (used in many rockets) is 20K.
69K is slightly warmed than liquid nitrogen (63K), and that is incredibly commonly used all over the world. And warmer than Pluto ;)
Yeah their comment doesn’t seem right to me. After a bit of googling I found this answer talking about heating things up to see relativistic effects, however because the velocities of the atoms in an object that has been heated up are random it’s most likely not possible to detect any relativistic effects. https://physics.stackexchange.com/questions/351773/is-there-a-relation-between-fluctuations-temperature-and-time-dilation
21F…someone grew up near the equator
I mean it is literally below freezing so even if you’re the tough kid wearing shorts in the winter the above depiction is not inaccurate.
69C° is just sauna
So you’re saying, that we should switch to specifying every temperature as a nice 69 and just switch out the unit?
Nice.
