The real breakthrough came when i found i could tie two middles together and rotate them to horizontal, thus making brand new lefts and rights, and raising the intriguing possibility that 'left', 'right' _per se_ are simply alternate FoR's on the same fundamental vector (coughGausseslawformagnetismcough - excuse me, that's cleared it)..

@reu tardio (I'm simplifying a bit) Higgs et al predicted the Higgs Boson because it neatly solved a huge problem with Yang-Mills Theory, which predicted quantum behavior very well but also wrongly predicts that electrons and quarks should be massless. The Higgs Boson theory reconciled observed particle masses with Yang-Mills and thus enabled us to complete the Electroweak Unification Theory as well as Quantum Chromodynamics. This "Life from Monopoles in Stars" thing doesn't solve anything. It's based on several HUGE leaps of faith. "Let's assume magnetic monopoles exist even though we don't know for sure. Let's also assume that they can break into two semipoles. Let's ALSO assume that these particles can exhibit chemistry-like behavior. And let's ALSO assume that they can interact with atomic matter." It's not really a scientific theory so much as it is just a cool idea with a lot of nerdy math behind it. It lacks any testable predictions since we can't exactly observe 'Monopolar Life' if we can't even observe Monopoles and know what sort of properties/behaviors to look for that would identify the existence of life.

@Signal 6EQUJ5 You are a bunch of atoms arranged in a bigger sea of atoms, you might call the less dense onse air and the more dense ground. but for any alien onlooker the difference between you and a gust of wind can be pretty hard to tell apart. Atoms are just small balls of energy, you have evolved to tell them apart because it's pretty neat to know that you cant breath dirt, and evolved to detect the light that travels through air but not earth as that is the light that matters for you. So you must start by seeing you own bias in life, and once you do you can begin to realize that other life forms can be as blind to your needs as you can be to there's. In its simplest concept, life is nothing more than a repeating pattern, books means nothing to a blind person. So maybe we don't see atoms as "topological defects" but we also pretty biased in our view. Consider that atoms might just be one way energy can form in space, like dark matter, or a form of matter that barely even interact with us can easily exist and have its own laws of physics (i mean stil the same physics just a other side of the coin.)

Asked biologist agrees that film from experiment depicts real living creature cell division, but filmed in very strange way - they did not told that guy it was plasma filmed. Because their machinery was not strong enough to generate long lasting plasma, they secretly prepare this kind of experiment in army project. That was when plasma entity was brought to life.

The great red spot is a great example, it consumes tinier storms that give it more energy, perpetuating it, while repelling storms that would reduce it's energy if consumed. There is obviously some kind of computation taking place to decide which storms get absorbed and which get consumed. A scaled up version of such a computation process might even lead to a kind of consciousness.

Question: The basis of life as we know it, is basic reactions between carbon based chemicals. For example on Earth we had a pool of “prebiotic soup” of these chemicals, and maybe a lightning strike gave it energy to turn it into the first primitive lifeform by chance. The point is, that given we have billion times billion times ... billion such event will result in creation of life by a high probability. Knowing how abundant these chemicals are in the universe, and how many such individual events happens, and assuming we are an “average” life, meaning based on our example, it took the universe 10 billion years to create life, we can calculate how many such events are required to create organic life. Of course it would be a very rough estimate... The point is, we can also look at these “magnetic reactions” the same way, and estimate, how often they happen in these stars. Are these faster, or slower than organic reactions? Are they more or less frequent? If these are orders of magnitude slower, and less frequent than organic chemical reactions, then we can assume that even though this kind of life is possible, or even inevitable (as anything with a non-zero chance must happen eventually), it is unlikely to evolve in “only” 14 billion years, and we can only expect the first such lifeform trillions of years in the future. Did anyone do such calculation?

We don’t know any other place where the chance of life would be significantly higher, so the probability of being created on Earth is much higher than the probability of being created elsewhere AND successfully traveling through space, AND surviving both the travel and the new environment. - There are currently no open questions about the creation of life on Earth, which could be answered by panspermia.

Exploring my theory of how black holes are responsible for the expansion of the universe. 1. If back holes are more dense than magnetar cores, the gravity of the black holes must be strong enough to expell the empty space between atomic particles, smashing together specific parts of atoms that possess mass and ejecting the contained vacuum of empty space between the particles, which has zero mass or any atomic property whatsoever, into space, therefore explaining the creation of dark matter and the expansion of the universe due to dark matter expansion. 2. The battle between dark matter and gravity may be the explicit balance that meshes particle physics and quantum physics. 3. If at a quantum level particles are appearing and dissolving at an unexplained rate, the dark matter and anti matter present at every level of magnitude throughout the universe is the explanation of the express creation/disappearance of particles at a quantum level.

The problem with being guided by beauty, and I think Sabine has this is mind, is that the Universe is under no obligation to appeal to our sense of beauty. Granted, Physics has made great leaps with beauty as a guiding force (or in some cases, a downright goal), but there's no real reason to expect the Theory of Everything to be amenable to our sense of beauty.

The visuals were on POINT this time! A great damn job!

Cheers - Dr. Breaux

Great thinking, I love it. It's a frequent misconception IMO that even decent-quality discussion about the fermi paradox & life elsewhere get wrong: being way too earthcentric in their thinking about how life may or not evolve. For exemple, assuming that because the moon has played an important role in the evolution of life, a large moon is essential for life. While I think we're very unlikely to even disprove formally this hypothesis, I think the sheer exercise in creativity is quite worthwhile. That and it forces us to formalize our thinking about what life, ultimately, is, or could be.

That picture of the 0-dimensional topological defect at 3:55 looks a lot like how positive and negative charges are described for electric charges. Which is probably not surprising, but I wonder why we have to invoke this "topological defect" description when discussing magnetic monopoles, but not for electric monopoles (electrons, positrons, etc.). Is it just down to the fact that we have experimental evidence for electrons, but none for magnetic monopoles or is there something more fundamental and different going on than my intuition would lead me to believe? Also as a community can we shorthand call magnetic monopoles "magopoles" or "magnetrons" or do we have to wait for their discovery first?

@samheasmanwhite

3 жыл бұрын

TBH this episode is excessively speculative for the series, the concepts here are pretty far from established science. Electric charge and magnetic fields are considered quite different because the way the fields work is distinctly different, if you look at the field lines the electric field it has monopoles but no closed loops, while the magnetic field has closed loops but no monopoles, at least as far as we've seen. For the topological defect thing I think that is from the particular string theory idea of what a magnetic monopole might be like, there are other ideas of how they could work. As for the name I think it's just that all the nice contractions were taken, magnetrons are a part of microwaves, magneton is a pokemon, etc...

@quacking.duck.3243

3 жыл бұрын

It comes down to Maxwell's laws. One of them says that the divergence of the magnetic field is always zero, which requires the magnetic field lines to all be closed loops. In fact, we observe no magnetic monopoles in nature, because a monopole would inherently have all the field lines flowing either towards or away from it, thus the divergence would not be zero. In the case of the electric field, Maxwell's laws says that the divergence is proportional to the charge density in that point. Charged particles act as electric monopoles.

@a-blivvy-yus

@@quacking.duck.3243 Matter being produced through interactions which actually produce matter/antimatter particle pairs is one way to explain the existence of matter in the first place. It's plausible that a monopole/antipole pair could be produced in a similar way, but their attraction to one another might be a difficult thing to counteract. If such a pair generating in between a pair of dipole magnetic fields, they might be pulled apart by a more powerful force than the one pulling them together. Assuming, of course, that there's a way to set that up to happen, and that they can exist and/or be generated in the first place, and that the conditions for them to form don't preclude doing so in such an environment.

@Nosirrbro

3 жыл бұрын

The reason it’s different is largely because the reason they arise is different. Electrons have their own field, while monopoles arise from another field having a region that simply cannot be in a low energy state by the laws of topology, so it’s forced into a position of high energy. How that exactly works out depends on the dimensions as said in the video, with monopoles being created from just a single point being forced into a higher energy state. If you want the best explanation you can get on this, I’d watch the biggest ideas in the universe series by Sean carrol, though it’s really long and this part is only a footnote.

This was absolutely fascinating!

I suspect that as well as a bias toward carbon-based and multicellular ideas of how life might look, on top of the expectation that "intelligence" necessarily involves developing a technology, we also tend to think of a narrow band of time and scale. I think we need to be open to and consider these larger possibilities. Keep up the excellent work of communicating complex ideas in a clear and straightforward way, thank you.
