  1. Some British politicians have given assurances that the UK would not geographically leave Europe. I wonder if we can trust them.

  2. There's also the Council of Europe though it's not an EU institution.

  3. "Very Large Colony". Those ants are as unimaginative in naming their colonies as astronomers are in naming their telescopes.

  4. The subtitles are technically correct, the best kind of correct.

  5. The Bottom and Top quarks used to be called Beauty and Truth quarks but the names were changed for some reason.

  6. The hypothesis is that with strange matter more of the quarks can be in the lower energy states of the system because there's three types of quarks and not just two (Pauli's exclusion principle) and with enough of it that effect might dominate the higher energy of the strange quarks themselves.

  7.  @SirButcher  "Most likely the uploaded subtitles couldn't handle the superscript formatting" Unicode has superscript numbers so there shouldn't be a need for separate formatting.

  8. Strange matter might have a lower energy state than normal matter but only if there's enough of it. The idea is that with three types of quarks more of them can be in the lower energy states of the system (Pauli's exclusion principle). But you would need a large enough clump of strange matter so that the effect from the exclusion principle could be larger than the higher energy of the strange quarks.

  9. How could colliding stars save us from the heat death of the universe?

  10. To my knowledge, the point is that if you have enough matter made of up, down, and strange quarks, more of them can be in lower energy states due to Pauli's exclusion principle. On the other hand, the strange quarks have higher mass/energy than up and down quarks but it might be that with enough of the strange matter the effect from the exclusion principle wins out causing the strange matter have lower energy making it more stable.

  11. It sounds like it would be easier to just live in space (in spaceships and spacestations).

  12. Imagine the universe like the surface of a balloon. When the balloon expands all the points on the surface get further away from each other but there's no special point on the surface that all the other points are expanding out from.

  13.  @hipdolly8382 : Expanding space nonetheless easier to explain with spherical model. The precise shape isn't that important for that purpose.

  14. It would be difficult to ensure that all of the strange matter and antimatter react and annihilate. More likely when you bring them into contact a small portion would react causing an explosion and blowing the rest away.

  15. As an analogy, water is more stable than a mixture of hydrogen and oxygen. Of course, water doesn't cause that mixture to burn, but if burning somehow starts, the reaction keeps going on until most of the gas mixture has been converted to water.

  16. This video would be more complete, if you had also talked about the case when the immune system succesfully fights of ebola.

  17. Luckily Golgafrincham sent all their phone sanitizers to us.

  18. The hypothesized effect comes from Pauli's exclusion principle. If you have three types of quarks instead of two, more of them can be in the lower energy states. The hypothesis is that in a large enough clump that effect might become larger than the higher mass/energy of the strange quarks making strange matter have a lower energy state.

  19.  @SolidFake : Now that'd be a sight to behold.

  20.  @justinphoenix21  It was just a Futurama reference.

  21.  @05danmea : They'd have to be more stable (i.e. have a lower energy state) or otherwise the catalysis of the normal proteins to prions wouldn't occur without energy input.

  22. 1) This is my best understanding. In quantum mechanics, there's something called Pauli's exclusion principle. It says that in a quantum system two identical fermions (i.e. half-spin particles like quarks) cannot be in the same energy state. When you have a clump of matter with three types of quarks (up, down, and strange) you could have more of them in the lowest energy states because you have more unidentical particles than you only had two types of quarks. The strange quarks themselves have a higher mass and thus higher energy than up and down quarks making them less stable, but the hypothesis is that if you have enough strange matter in a clump the effect from Pauli's exclusion principle wins out this effect making the strange matter have a lower energy state than normal matter.
