Is It Possible To Get To Absolute Zero? | Neil deGrasse Tyson

I could never put it on paper, but for some reason everything he said made perfect sense. I don't know if that makes me smart, or if it makes me stupid, but it makes sense either way.

[kenkurogue]

Since movement seems to be a requirement for this universe, if we WERE able to figure out a way to get a particle down to absolute zero, would that particle just wink out of existence completely then?

[maryfrawley]

My friend took his temperature down to absolute zero. He's 0K now.

[mauzeking]

It's really simple it's a repeating divide-by-two problem. Say we take away half the heat in an object in the first round, then in the second round we take half again, no matter how long we keep repeating we will never get to 0, even though we get closer all the time.

I don't see why we would need something colder only something that can handle the pressure necessary to reduce the heat.

[willywonka]

Simply said - heat is movement at the molecular level.

[kiq]

So, how slow ARE things moving at micro kelvin ?

“Niel I just wanted to see if you had seen my keys”

[mikey]

What is the frequency of that vibration.

[alexchudilovski]

So you saying I am could.
Would you also say that, for instance, titanium is could because it does not interact with water? Maybe there is another reason why two elements do not engage in reaction, and it is not due to heat.

Bro walks into college class.
“We will NEVER know this stuff!”

[BabyQuasarX]

As far as we know about quantum physics, there is no such thing as a absolute zero

[thetoyodacar]

So something cold cannot stay so infinitely even without external heat because it's always moving on a quantum level?

[bricesuire]

Yea and it would take an infinite amount of work to get there. Sooo theoretically impossible 🤯

[stuartbrock]

it has to do with the particles having matter, doesn't it?

[pdorism]

Wrong. Just because a quantum system has some energy at ground state, doesn't mean it has entropy. There is only one possible microstate, therefore entropy is 0.

[stewartbugler]

Fascinating... I remember trying to gather life energy in my hand yes im talking about chi. Most times its described as a warm energy and I found it interesting cause any time I did that I figured it was electron potential being channeled or something... however they are negatively charged... so I figured try gathering positive energy in my hand and instantly it got super cold and incredibly sensitive.

I didn't think much of it but this quantum fact could actually help to explain alot about it.

[jamesmartin]

I suspect that if you could find a way to subvert quantum issues and reach absolute zero, it would have an Ice-9 (Vonnegut) effect that would spread to all reality. Pure speculation on my part, obviously.

[donaldkasper]

Look, all those problems in my taxes are not my fault, I got quantum calculational errors that are beyond my control.
