Neil deGrasse Tyson Explains Why You Can’t Reach Absolute Zero

Cool things happen at low temperatures. In this StarTalk explainer, we’re cooling things down - way down. But how cold can we actually get? Neil deGrasse Tyson and comic co-host Chuck Nice investigate the limits of temperature and a lot more.
You’ll learn why there’s really no limit of how hot you can make something. On the flip side, we dive into why making things colder is a different story. How do you create a place where there is no heat? You’ll find out more about the Kelvin scale or absolute temperature scale.
Neil takes us through the process of cooling things down. Discover the differences between temperature and heat energy. We explore the vibration of particles and dip our toes into Maxwell-Boltzmann distribution. Then, Neil tells us why we can never philosophically or theoretically reach absolute zero.
To wrap things up, we investigate what happens when quantum physics take over. Discover more about superfluidity. All that, plus, you’ll hear about the Bose-Einstein condensate and how we can “shape-shift” matter.

@@martinwillemse8923 you cannot go faster than the speed of light because LIGHT CANNOT GO FASTER THAN LIGHT,remember that. Anything that has mass cannot reach the speed of light,and the universe in the future will expand at the speed of light at which point we cannot even see distant galaxies or even stars "but no object is actually moving through the Universe faster than the speed of light. The Universe is expanding, but the expansion doesn't have a speed; it has a speed-per-unit-distance, which is equivalent to a frequency, or an inverse time" nothing can break the universal speed limit.You can warp space,you can quantum tunnel,you can create wormholes BUT YOU CAN'T GO FASTER THAN LIGHT. The galaxy maybe is moving with the expansion but the speed which it goes through space is not lightspeed, maybe lets say 170 mp/s,thats really fast,infact our galaxy is hurdling through space at about 130 mp/s but it doesnt go as fast as the universe is expanding right?

[@ToiletPaper2020]

I can hypothesize what below zero would be. But first, it's just easier to start with nuclear physics. What is a nuclear bomb? What is an electromagnetic thermonuclear bomb? A regular bomb is a 3d bomb and a nuclear bomb is a 4d bomb that either implodes or explodes the 4th dimension in a nuclear chain reaction. An electromagnetic nuclear bomb decreases the electrical charge of the gravitational field of space through the magnetic field. This pushes the gravitational force of Dark Matter, Dark Energy, and the gravitational force of the mass of space into the area of the mass of space where electrical charge is decreased without the "cushion" of the gravitational field of energy to slow down the impact with the force of acceleration and all things in motion stay in motion. So now to below zero. When we get the breaking point of where all things in motion are staying in motion because the gravitational field of energy is no longer pushing mass apart we have universal collapse. Take a step back and go to the geometrical shape of space. Space is expressed as parallel circles with infinite curvature forming flat parallel lines in the interior surface, accelerated expansion in the parameter functioning, and the gravitational field of a singularity observed in its gravitational field of Dark Matter and Dark Energy. A circle around a circle until infinity always accelerates and expands. Infinite and zero are non-observable in 3 dimensions and we observe them by measuring them over time to differentiate. Infinite is non-observable over time and zero is. Zero has no beginning and no end. Infinite is both the beginning and end. The beginning of infinite curvature is also the end. So the singularity forms a flat parallel line between each edge of the sphere that forms flat parallel lines. A single instance of infinite temperature at all points of space. But, when there is explosion, the mass, density, and volume of the singularity do not increase. So the universe inside the singularity at the point of universal implosion is negative infinite while the singularity remains infinite. Like a negative and positive charge.

[@ToiletPaper2020]

@@jareddiscipio1768 Ok, so to clarify. I typed up what I summarized with absolute zero. It's too long to text. I. The end you get infinitely negative or in the sense of absolute zero, infinitely negative zero. drive.google.com/file/d/1wnxA-civlDMswVXRAnF7gu3nFHzEgPtL/view?usp=drivesdk You seem to think I care about how you make a nuclear bomb. I don't. I don't care one bit. And I also don't care how much c4 you have, you're never going to effect the gravitational field. Nuclear bombs merely have the difference of a chain reaction that effects spacetime and not just space. And you can explode cra* all day, it's never really going to do anything to the universe as a whole because that is how the universe was created. Expansion. Now..use magnetism and decrease electrical charge and the universe will implode because the gravitational field deflates.

But this is how exactly how I teach. There are certain common speeds at which kids and students hear something, grasp it and then internalise it. A good teacher will find that rhythm and will never go too fast or too slow. If you go too slow, your intelligent kids' minds will wander and they will end up missing bits of information or fail to form a cohesive picture. If you go too quickly less intelligent kids will just fall behind because they never have time to process and internalise information.

Unfortunately he explains it in a way which is not entirely correct. Absolute zero is well defined in quantum mechanics with an example being in complete darkness, the optical system is in a Quantum Ground State and the thermal reservoir of optical photons is zero kelvin. The more important concept as above is the Quantum Ground State, the lowest energy state of a system. No temperature is defined for a pure quantum ground state because the state is known, and temperature is dependent on the system (in many systems the QGS energy is just above absolute zero).

[@krisbrixon]

Mr Nice is picking up more and more science with every video. It's like that if you expose someone to science, they might get smarter over time. Early on, his mind was always blown, but these days he is following along more and more. We can all wish we are like Chuck Nice.

[@ermiasd2695]

Couldn’t agree more, krisbrixon. Love this show

[@jackshit6088]

I wished, Neil deGrasse Tyson would have given Chuck Nices' idea about combining the fridge with an oven a bit more of a thought. Geothermal heat pumps work in a similar way as Chuck suggested it. If you have already some heat, you won't need to add so much energy to reach the desired temperature. Thought from the perspective of an engineer.

[@5353Jumper]

Yeah in the last few months many of his comebacks have been with some high level understanding of multiple disciplines. Way to go funny man, y'all are getting pretty smart.

[@LarryManiccia]

This guy is awesome. If only all teachers and professors taught like he does. He has such a way of explaining things that makes it easy to understand even if you don't have an engineering or physics degree. Super interesting to listen to as well.

It is possible to go faster than the light, if you are dreaming that there is a big bang that we are in. We can observe galaxies very far away that have 90% of the speed of light and let's just start there to reach the speed of light, it takes a little time, but then you also go faster than light and not on the next. once so very difficult to understand system, we first go to the next galaxy, with a simple rocket, we refuel that for a while and fly to the next galaxies and if you do that you will also visit our galaxies, to get to drink us a cup of coffee and you also get a cookie, then you continue to the next galaxy until you reach a galaxy that also has 90% of the speed of light compared to us and you go at that moment 1,8 times the speed of light and we then act as an observer, who can perceive that you have completed this task and you have not been able to perceive the base from which you departed for some time, just like we are rescuing the big bang. aunts can perceive and can assume that there are also galaxies behind that that we cannot perceive, but faster than the light, how that is possible all the time, that is because you believe in it.

Love Neil and Chuck. Neil, for being the best continuator of Carl’s legacy in science promotion and education. Chuck, for being the best version of what we all are when we are curious and are not afraid to ask. I could have commented this in any StarTalk episode but I did it on this one. Maybe a nice bottle or Malbec helped a lot. Keep them coming, you guys. I know I’m gonna watch all StarTalk stuff several times and, at least, make my kids aware of its existence.

You didn't mention neutrinos, but you cannot filter them out since they permeate all of space. They normally don't interact much with most matter particles, but they might have an effect on the micro-temperatures. 👍

[@peregrinef3203]

As a high school teacher, I explained why measuring angles in degrees was rather arbitrary. Then their task was to come up with their own unit of measurement, tell me how many of that unit would make a circle, and give me a method to convert from degrees into that unit. I used this to then jump into radians. It got their brains thinking in a way so they could more easily accept a different form of measurement for angles.

[@jewfroDZak]

The poetry of Sagan's thoughts, along with his childlike wonderment and love of solving mystery, make me cry cathartic tears of appreciation of the beauty of our universe. Regularly, every few minutes in the middle of something he's narrating, I vicariously feel the emotion behind the words he uses to describe his personal search for truth and the waterworks start for me. I can see the comparison between him and Neil. It's in the honest expressions of enthusiasm about science and fact-finding that they routinely display, I think.
