+TED BEH Actually Cold Fusion is even hotter than that. Cold Fusion means getting fusion to occur at any temperature lower than it amount of energy it outputs. The temperature Fusion happens in a sun is already way colder than the energy output of the fusion which is why stars work as nuclear generators. The reason fusion happens at the lower temperatures on the sun is because of the extreme amounts of pressure due to the high gravity. On earth at 1 Bar Hydrogen needs to be so hot for fusion to occur that the energy output is not nearly enough to cause more hydrogen to fuse (for a chain reaction) If we could match the fusion temperatures of the sun that would already be cold fusion. The problem is finding a way to pressurise the system, or finding another way which does not require the system to be pressurised. (Remember, were not talking about like 100-200 psi, were talking in the range of 3.6 trillion psi.

"Even at absolute zero, things do not stand still". I thought that the reason why absolute zero can never be reached is because it would violate the Heisenberg Uncertainty Principle. Absolute zero is the temperature at which a body has zero internal kinetic energy, and hence minimum internal energy (as you still have some internal potential energy otherwise the body would collapse into a singularity). Can anyone elaborate on what he's saying?

If the Van der Waals-Force is weaker between two helium 3 atoms than between one helium 3 and one helium 4 atom, why doesn't the pure helium 3 on the left side evaporate first? Or are you just simply changing the temperature of the right tube?
@andreamorello742510 жыл бұрын
You are an excellent logical thinker! Indeed, that's how we operate the machine. I didn't mention it in the video, but there is a small heater near the top of the liquid level on the right hand side that keeps it a bit warmer. The He-3 on the left hand side still wouldn't evaporate because there is more He-3 gas compressed onto that side by the back of the pump. But heating the right hand side is indeed necessary to increase the rate of distillation - just like you heat the distillation column to make vodka...

Andrea Morello Thank you very much for the response and the kind words!

@robaus2310 жыл бұрын
Andrea Morello You mentioned in the video that the pump takes these hotter particles from the right side, and pumps them back into the top of the left side. My question is: Wouldn't this heat up the left side, essentially negating the cooling when H3 moves into the H4 area? Where is the heat going? Because the left side is getting closer and closer to 0K, then being heated up on the right side (back to the boiling point?) and pushed back into the left side (at presumably a much higher temperature than the boundary between H3 and H4)?.
@andreamorello742510 жыл бұрын
Yes, you're right. Among the many details I skipped in this explanation, is how you re-cool the atoms that are reinjected on the left hand side. This is done in a number of ways. First you push them through a flow impedance attached to a small pot of pumped 4He (separate from the rest of the circulation system), which cools them to 1.5 K. Then, from there downwards, you make counter-flow heat exchangers, where the cold 3He atoms coming up from the right help cooling down the hot 3He atoms coming down from the left. A simple way to do so is to put two tubes of different diameter one inside the other, and coil them around to make the length longer. So basically, the left and right hand side of the U-tube are not really going up straight and separately as I've drawn them on the board, but you put one inside the other and wound them around. It's just a bit messy to draw it... In fact, if you look at the photo that Derek used as the "cover image" for this episode, near the bottom of the image you will notice something that looks like a coiled-up gold-plated tube. That's the heat exchanger. You only see the outer tube (which would be the "right hand side of the u-tube"), there's a smaller tube inside (the "left-hand side of the u-tube").

How do the scientists know if they recieve a false positive from the Grav Wave detector. It would seem very easy to accidentaly measure seismic activity, or even a foot step, when you measure changes at 1x10^-20m. Can anyone explain this to me please?
@andreamorello742510 жыл бұрын
Good point. What you need to do (and is being done) is to build several detectors, in different parts of the world, and look for coincidences. That is, look for events where the same signal appears in all detectors around the world at the same time.

Andrea Morello I have a somewhat similar question. You mentioned at the end that people have devices that, when cooled, can detect very minuscule changes of width of the cooled mass (1/10 of the one expected from a passing gravitational wave). Now, how are they testing such devices to say that they can reliably measure such small changes? Obviously you can't just fire gravitational waves at an instrument.

TheFeatInk light has been associated with knowledge and darkness with ignorance for a very long time, going all the way back to Prometheus. "Lucifer" is a Latin word meaning "light bearer", the first story of the bible is basically just a really long way of saying "ignorance is bliss". Christianity in its very first story and it's continued vilification of Lucifer makes it clear that Christianity is a religion that sees virtue in stupidity.

iWhacko No no no, have you every heard of super conductors. It works on the premise that when a superconductor is cooled below a its critical temperature it becomes a conductor without electrical resistance. At this point information is not limited by the conductor's resistance because at this point information propagates through the super conductor at the speed of light. Just to note, this can be applied to regular conductors, but when cooled, regular conductors like copper still shows some resistance and would not be as effective as superconductor materials, but would still work.

@vannilesoep9 жыл бұрын
+BowGunner What +pdavid24 says does seem to make sense, but it is not correct. The whole idea here is that Helium, being a noble gas, doesn't bond with itself (or other elements), as he explains at 1:38 . So if it doesn't react with anything, would it make sense to say that Helium-4 is 4 helium atoms? No, indeed it doesn't. The '3' and the '4' are used to describe which Helium-isotope we are talking about. An isotope is an atom in which the nucleus is made up of a set number of particles. Basically this nucleus (the core of an atom) is made out of 2 types of particles: protons and neutrons. All Helium isotopes have the same amount of protons (2) and different amount of neutrons. The numbers 3 and 4 are used to describe the total amount of protons and neutrons in the nucleus: Helium-3 has two protons and 1 neutron and Helium-4 has two protons and 2 neutrons. Since protons and neutrons have approximately the same mass (and the mass of an electron is very low and may be neglected) there is a 3/4 ratio of mass between the two isotopes :)
