A good way to think about temperature in this context is that it is a measurement of how quickly atoms or particles are vibrating. When atoms/particles stop vibrating, they reach the lowest temperature it can possibly reach… at which point, our scales for measuring temperature stop, and nothing exists below it. This is at 0 Kelvin, –273.15°C, or –459.67°F. These represent the floor for temperature, so temperature cannot reach -10,000° because it’s physically not a thing.

Temperature is a measure of particle movement. All movement stops at absolute zero, which is 0° Kelvin, or -273° Celsius, IIRC. What you're suggesting is literally impossible.

Absolute 0 is -273,15 Celsius. At this point molecules are just frozen in time and don’t move so it’s not able to produce heat.

This is very cool, but I'd like to see this of just the earth spinning on its own for a while too.

Ya, same technique as those 3d eye illusions from the 90s.

Thanks! I learned how as a small child from Magic Eye books, I loved illusion puzzles

This is FUN! They both work parallel-eye for me! 👍 I learned to free-view after one too many beers at geology Field Camp 38 years ago 😎

For those who don’t know:
Unfocus your eyes such that you see a double vision (4 sets of earth moon, 2 on each side).
Then move your head closer or away from your screen until you merge the left and the right double vision into a single one in the middle.
That will give you the illusion to be looking at a 3d picture.

>This animation features actual satellite images of the far side of the moon, illuminated by the sun, as it crosses between the DSCOVR spacecraft's Earth Polychromatic Imaging Camera (EPIC) and telescope, and the Earth - one million miles away.

I made this stereo gif by using motion parallax to get depth, where you use the next and previous frames to make a stereograph. The top row is for cross-eye viewing, the bottom row for parallel-eye viewing
While this illusion is cool, the moon does appear much closer to the Earth than it is in reality. The moon is vastly farther than the impression you'd get from just this GIF alone

Reply to Blue Origin awarded NASA launch contract for Mars mission (Studying magnetic field) by kuroimakina
This is great for Blue Origin! Competition is fantastic at pushing for better tech and safety standards along with SOP and culture at work.
I seem to recall early in Space Xs life people were look forwards to competition and welcoming it. Same thing happened with Tesla with Musk and the fanbase welcoming it. Then competitors come and all goodwill leaves with people wanting them to fail and quit before they even attempt anything.... thats not productive for anyone.
Also I remember some people here and at a certain Private space sub reddit wishing for the SLS to explode on launch so NASA can just abandon it... Toxic team cheering is not a good look.

Do you have something which isn't YouTube. My trust in YouTube is worse than Facebook.

https://en.m.wikipedia.org/wiki/Absolute_zero
Snippet to answer your curiosity:
It is commonly thought of as the lowest temperature possible, but it is not the lowest enthalpy state possible, because all real substances begin to depart from the ideal gas when cooled as they approach the change of state to liquid, and then to solid; and the sum of the enthalpy of vaporization (gas to liquid) and enthalpy of fusion (liquid to solid) exceeds the ideal gas's change in enthalpy to absolute zero. In the quantum-mechanical description, matter (solid) at absolute zero is in its ground state, the point of lowest internal energy.

Quantum gas goes below absolute zero
