An Astrophysicist's Top 10 Unsolved Mysteries

[@DrBecky]

A few of you have pointed out that Anton Petrov (and recently SciShow Space) did a video on a possible explanation for the 11-year solar cycle to do with the alignment of Venus-Earth-Jupiter every 11 years or so. That idea comes from a paper that was published last year that looked into a few other explanations for the cycle as well, but it's still only a hypothesis, not a fully accepted theory, so I've still included "Why does the Sun's magnetic field flip every 11 years?" in my list. Here's Anton's video explaining the alignment hypothesis in more detail: kzbin.info/www/bejne/qnO2lKyfjq6biZY And SciShow Space's video: kzbin.info/www/bejne/iKq8qWWEr6t3q7s And here's the journal article that this idea came from: arxiv.org/pdf/1803.08692.pdf

[@arctic_haze]

I do not think that paper closed the matter. There is still the problem of missing mechanism of turning the minuscule gravitational changes into visible changes of the Sun magnetic field activity.

[@empathy_is_only_human]

Love the recognition of Anton Petrov and his "Hello wonderful person" introduction. Here are my ideas about how to answer your list of unanswered questions. 1. A neutron star who's Schwarzschild radius has grown larger than the radius of the star. Comprised of a unique form of neutronium wherein its constituent neutrons feature massively high numbers of quarks within an otherwise classic neutron architecture. Thus raising the neutron degeneracy pressure needed to superimpose two such particles to insanely large values. 2. The universe isn't expanding, but instead is just returning to its pre 'big bang' state of equilibrium in what might be an infinite expanse of space-time. As it flows past galaxies, a miniscule amount of kinetic energy is transferred into that matter causing the expansion to accelerate. 3. See the answer to number two. 4. Referring to the answer in number two, dark matter might be relativistic mass generated by space-time speeding past all the matter is the observable universe. 5. I don't know. The three words that signal the beginning of wisdom. 6. Referring to answers one and two. Having reached a point where neutronium could no longer generate more massive neutrons by adding quarks to the existing structures. Two by two at or near the core neutrons begin to superimpose and annihilate each other generating heat. Material naturally falls into the void left behind marking the point at which the neutron star/black hole implodes down to the size of a point with the diameter of a single plank length. With the phase shift into heat energy, space-time, no longer bound by mass is pulled outward omnidirectionally at faster than the speed of light. At some point this dispersion allows the temperature to cool sufficiently for matter to form again. And we have the various elements we understand as the evolution of the universe from the point of the big bang. 7. The only thing I can say on this is that matter existed first prior to coagulating into a form sufficient to form black holes. In other words I don't know. 8 & 9 are again things I have no idea of how to answer. 10. For this one, I would refer to an idea not of my own but which has been postulated. All life is an emergent property or consequence of the second law of thermodynamics. Entropy (the measure of disorder or chaos) always increases in the aggregate. Contrary to current theory however I think that entropy is caused by the expansion of the universe as opposed to it being the cause of the universe's expansion. To explain the idea that life emerges from entropy consider that all life consumes other organic matter and or inorganic sources of energy. The results of this is that post consumption and even post death of any given unit of life. The material either expelled, or that remains post death. Is always in a state of higher entropy than what is consumed or what was alive. Thanks for reading my ideas. While this list isn't comprehensive. Please feel free to pick it apart with criticisms and or questions. I love discussing this stuff and welcome learning the reason this isn't the way we think our environment(universe) works. But yes I do understand that there are some elements that are unmeasurable / observable. Please do better than that if you'd like to engage me in conversation on this topic.

2 thoughts: (1) Imagine a bubble of compressed air being released at the bottom of the Mariana Trench. As the bubble makes its way to the surface, it expands. Once it reaches the surface, it pops. Is it possible that our universe isn't expanding because it's being "pushed" outward as it ages, but because the environment that surrounds our universe is becoming less able to contain us within some boundaries? I know, that suggests that an environment outside our universe exists and we are indeed expanding "into something", and that would challenge existing thought on space/time. (2) Life elsewhere. I suggest to others that the universe is actually teeming with life - we just haven't found it yet. The question is, "what form of life?" Even on Earth, paleontologists generally agree that any species that has gone provably extinct never reappears. If we consider the amount of acorns, dandalion seeds, sperm cells and other fertilizing material is required to get 1 viable organism going (a sperm whale will produce 420 gallons of sperm and if lucky produce 1 calf), we can assume the universe is no different anywhere else. So while we may not be "alone" in the universe, I think it's highly unlikely that any life form is just like us. That would make absolutely no statistical sense at all given the fact that the ration of homo sapien to all other life on Earth is something like 1:9,000,000 (and likely more rare than that if we knew the total number of unique species that ever inhabited Earth). But does vegetation exist? Have lifeforms evolved from algae elsewhere? Yeah, I think it's highly likely. They're just not zipping around in space ships, or making KZbin videos. And even if some "highly intelligent lifeform" does exist, physics applies to everyone. Why would they come here given what they are likely to observe of our galaxy, our solar system, and our planet from many (possibly millions or billions) light years away? Life finds a way - in whatever form presents the least resistance to existance. Life doesn't have to be like us. Nothing else on our own planet is.

[@tSp289]

Fun fact (unless you're trying to concieve): only about 8% of conceptions result in a live birth, even under ideal conditions. 92% end, but most of them are so early on that no one ever notices. Also if they do observe Earth from a great distance, they would need some very good equipment to notice anything interesting about it unless they're really quite close.

Great video. :) One small thing: on the multiverse theories, while this universe is expanding in the sense that things are getting further apart in the relevant senses, that doesn't mean that we are getting closer to other universes in the multiverse, or that those universes are getting smaller to make room. The entire thing (all of the universes, and the multiverse / metaverse itself) could be expanding in the relevant dimensions; just as in the usual "think about raisins in a loaf of bread" or "think about points on the surface of a balloon" metaphors.

[@dirkvillarrealwittich]

A black sphere as a part of the singularity makes sense since we live in a three dimensional world. A circle would be only a two dimensional object, which does not match the facts. The biggest issue is to fit a singularity into a three dimensional space, or should I say space-time fabric? This singularity as far as we know rips the space off with a hole to which we do not have access to and it seems that we never will. I am anyway glad that there is still plenty stuff available for research.

Hi Becky, Maybe the reason why there are these unexplained mysteries is simply that we have a fundamentally wrong understanding of gravity! The main premise of Newton and Einstein's Gravity = Object's mass. Yes, the calculations support this for visible objects, but invisible objects remain unsolved mysteries. Let's just assume a different premise Gravity = Space mass, in other words, gravity belongs to the density of space rather than the density of matter. This would solve many of your existing mysteries... -What is a supermassive black hole? it is the accumulation of space density that increases toward the center of each galexy to form a vortex that spins space around an empty meeting point, it isn't a supermassive object and the center hole doesn't possess any gravity. Space is bent and light is twisted away like a fiber optic cable, rather than being trapped over the event horizon. -What is a stellar black hole? The accumulation of space density that remains after the star has blown up. Yes, the gravity hangs around even after the star has left its location. -What is Dark Matter? Dark matter is simply the accumulation of increasing space density that has built up within galaxies over vast time scales -What is Dark Energy? Dark Energy is the same as Dark Matter but at the opposite end of the spectrum. I would class Dark Matter as a negative space density and Dark Energy as a positive space density that naturally repels each other. They are both made of the same space fabric, but one is negatively dense energy and the other is positively dense energy. -How did the visible universe form? The collision of Dark matter into Dark Energy forms matter. These two basic ingredients are now separating back out as they distribute their energy back to their equilibrium state. So the big bang was more of a big collision -What came first the Galaxy of the black hole? Well, that's simple, as gravity accumulated from matter and into dark matter, it accumulated together to form an increasing density toward the center which in turn began to spin, and form the vortex which we observe as the black hole. Thank you for considering my point of view, I would hope that it may inspire mainstream science to take a fresh look at Gravity and find better answers to our mysterious universe.

[@KaKrassh]

Just wondering if dark energy, dark matter, or antimatter behave differently than regular/"normal" matter when pulled into the event horizon of a black hole or a black hole itself.

[@jeffhubbard6185]

For antimatter I think it would only behave differently if it collided with standard matter when sucked into a black hole. As far as the others, I doubt they'd behave differently but I'm also really curious!

"What came first, the chicken or the egg?" isn't an unsolved mystery though. It has a clear answer in evolutionary biology, and that answer is that delineations between species are socially constructed.

[@MeoWHamster]

It is a solved mystery. The egg came first, it was layed by a "proto-chicken", the evolutionary precursor to the chicken.

[@Tamamo-no-Bae]

@@MeoWHamster Depends on what you define as an egg. Is it something an embryo grows in? Then eggs have existed ever since the first complex animals appeared in the Pre-Cambrian. Are we talking Eggs with a shell? Then you'd be looking at Proto reptiles in the late Carboniferous/Early Permian such as Hylonomus. But yes, eggs existed before chickens. However you can make the saying relevant again by asking a question that we have not solved. What came first? An egg or complex animals? Did the first complex animal reproduce like it's precursors and it then laid eggs? Or did it's non-complex parents lay the first egg through a mutation?

Hi Dr Becky I liked your Cern program, on antimatter being produced by protons being colided into a metal target at high speed. The Sun also colides protons, at high energies.The core of the Sun would have metals. Would antiprotons be produced causing the anililation with protons, causing the Sun's energy to increase. It is know that the solar wind which is photons and +ve ions acelerating away for on the Sun. Could it be that the antiprotons being -ve will stay as energy. So the we cannot see them may be the missing antimatter?

I feel like it's more likely that we'll evolve into different versions of humans before we find proof of life outside our planet. Like while developing the technology to try to visit planets far away, we'll already have developed the tech to visits planets close by. There's already stuff about colonising Mars (not sure how realistic that is, I'm no expert) so in the decades or centuries it takes to develop technology we'll probably have already started a few civilisations in places that could encourage biological changes to occur in humans on those planets differently to how it would occur to humans on Earth.

First I wanted to say that I really like your videos because they make me think. And regarding some of these questions. Have anyone ever pondered if there might be other mirror dimensions/universes of antimatter created at the same time of the "big bang" and may have a spread gravitational interaction with ours, this would explain the gravitational effects alluded to "dark energy" which cause the universe to expand and the lack of antimatter. On the other hand, there might be very massive stuff affecting our observable universe beyond our visual reach that is pulling our universe apart. On the third-hand dark energy might just be space being created constantly like a balloon being filled with air in all directions.
