Below absolute zero?
I have heard stories of planets with storms below absolute zero. Anybody have screenshots of this?

I have yet to see or hear of a planet like that, but keep in mind that absolute zero = -273.15C or 0 Kelvin.

If they do drop below absolute zero, then thats impressive considering in a controlled environment scientists still can't reach absolute zero, let alone an open system like a planet!
makes sense you've got absolute zero plus wind chill....don't go looking for science in this game, they have very firmly rooted themselves to science fiction

i'm a carbon based lifeform that eats other carbon based lifeforms but i'd likely die if you feed me the contents of a toner cartridge. which sums up the feed mechanic

In reality it wouldn't be possible, since 0 Kelvin is the theoretical complete absence of movement in every atom at that temprature, but in video game logic who knows.

Shame about the science fiction. No astrometry, no atomic information, no chemistry, no cellular biology, just fiction with no science. I hope future updates and mods will tackle the lack of any content which is meaningful in the real world. The game could be a great way to explore many areas of science and maybe inspire people to delve deeper into areas which interest them. I would have thought at least there would be some way to explore procedural generation itself, again this may come in future up dates or mods, I hope so.

i had -305 (extreme + storm), didnt think to take a picture of it. The numbers don't actually mean anything im sure. I dont bring the hud up often because even at those temps, there's nothing to worry about.

Actually, scientists years ago now have broken the Absolute Zero barrier.
I'm surprised this hasn't been well known.

Seriously, it's no longer a pipe dream.
However, a planet in this game getting that low, shouldn't happen, and sounds more like a bug.

Interesting, I guess I didn't hear about it since for all practical purposes there isn't a need to reach or even break absolute zero apart from scientific discovery. (Correct me if you find somethign else)

Most likely it is a bug if the devs coded a floor for what the tempreture could be, but forgot to set a limit when storms are active.
Or absolute zero is lower in NMS universe.

Absolue zero is absolute. Doesn't even make sense to "go below it". It is defined by the point of minimum enthalpy and entropy of an ideal gass where all molecular motion ceases. Since real substance depart from ideal it is not the actual lowest enthalpy state possible...but it is cessation of molecular motion which is hard to get lower than.

0 Kelvin has been breached, by a quantum gas. As pointed out multiple years ago when it was an actual big deal in the scientific community.

I'm not even sure why people are still debating the concept of going below Absoulte Zero when it's already been done. :)

You're talking about a Bose-Einstein condensate which follows a rather different definition of 'temperature' that can go from negative to positive infinity and has to do with statistical mechanics. 'Normal' matter has temperature defined by the average kinetic motion of the atoms. So there are different types of temperature. And the difference in a BEC from Norma matter is that in the BEC there are no individually identifiable atoms.

And I might add that this negative temperature region is actually hotter, such that if brought in to contact with somethin in the + Kelvin range heat would flow FROM it. Odd yes and I'm pretty sure they were not thinking of a BEC put in to this very odd and utterly artificially induced state.

Okay then. My misunderstanding of Quantum Physics.
I just thought that by cooling down the BEC to below Absolute Zero means that the 0 Kelvin barrier is breakable.

Just a very different definition of temperature and a very odd system where the sudden change in energy brought on by abruptly changing the optical lattice the BEC was locked in to resulted in a mathematical negative temperature. Of course at the same time the BEC took on a negative pressure...again a mathematical description of an energy and entropy change. The BEC is still warmer than absolute zero given the direction heat would flow...but the value is negative.

As Feynman said; if you think you understand quantum mechanics, you don't. I sure don't claim to!
Wow. I'm pretty science savvy and I hadn't heard of that experiment. It's pretty damn cool.

As for the credibility of science in NMS, well... I wouldn't even know where to start listing terrifyingly wrong science in this game. It's just a game, though, and for some of the mechanics to be cool and fun, science has to go out the window.

As for the implications of temperature in game mechanics, the more extreme the weather and lack of atmosphere, the faster it's supposed to consume resources for your suit. I've noticed this seems to be the case, but (especially with a fully upgraded suit) it seems to be a fairly small rate of change.

people forget that it is not a number, but movement.. and you can not be moving less than 0
Messaggio originale di davidb11:
Well, technically, according to the principles of momentum, you can be pushed backwards, which is a negative movement, I.e less than zero.

I was not aware that the measurement of temperature was about movement though.

I suppose that is why there's an absoulte Hot. :)

I take issue with this statement. Movement is a vector quantity. Speed is a scalar quantity and can be negative in relation to another speed value.

Being pushed backwards, however, is not negative movement. It's a vector. The velocity of backwards movement, or momentum when you apply mass, can be expressed as a negative in relation to another vector for the purpose of determining combined vectors.
Messaggio originale di davidb11:
Okay, okay. All my knowledge is rusty, I get it. :)
It's been 15 years since I even had to use vectors or movement, or physics in general.
I apologize.

It's cool, man. The more you know! :)

You weren't entirely wrong. Temperature itself IS a scalar quantity that can only rise or lower. But that value is a result of particles moving. Just like speed is a scalar quantity, but in real-world scenarios, it's dependent on an object moving along a vector.

And as someone above said, when you get into quantum mechanics, reality takes on a whole new meaning.

And mathematical expressions can do some very strange things in special events, too.

I've found that there's a point in physics (when you start dealing with quantum things) that virtually everything you know is wrong and any statement could technically be true. Someone will probably say that what I just said is not correct, and they're probably right.

Probably the best concise description of this I've ever heard! Well done!

As far as I understand it they effectively created an environment in which the electrons were in a high energy state at rest--effectively the inverse of what is naturally observed. Instead of particles becoming temporarily excited, inscreasing temperature, particles become temporarily slowed, decreasing temperature. Absolute zero, in this environment, is essentially the highest point instead of the lowest with only negative values being possible. The thermal output of this set up, however, is really really hot!
