    Danish seismologist Inge Lehmann, that proved that Earth have a double core, was also in some way overlooked. Sadly most in her homeland. She lived to be 104, and published until her late 90ies.

    The theory that captures my attention the most is that the Big Bang was actually the discharge from a white hole. It would be connected to the singularity of a black hole, like a cosmic tunnel, and only exist for a tiny fraction of a second before collapsing. This would explain how all the matter of our universe appeared at once and was so hot that atoms could not form for a long time since the black hole would have chewed up all the particles into the tiniest pieces. If we were to see one today it could very well create a second universe out of those quadrillions of bits.

    In my science fiction (and in no way related to reality) mind, white holes are the “exhaust vents” of black holes. Some sorta quantum entangled singularity tied to a black hole, and the only reason we don’t see them often is because they’re only currently detectable when they emit energy, which would only happen when their linked black hole is absorbing matter/energy. That would solve the entropy problem and it makes me think wormholes are possible. Don’t at me I know it’s wrong but it’s cool to think about lmao

    I personally think hypothesis the a white whole is not only possible but is in fact the reverse of of a black whole. Further more is the start of a new universe. I have no evidence of that. But what a hypothetical scenario. I know I’m not the first to think of it. I have other hypothesis that are perhaps a bit more original.

    That sounds reasonable but what evidence or calculations indicate this? Though I could see it's rotation affecting an accretion disc but I cannot fathom how material would be removed from a black hole when that literally requires something going faster than the speed of light not to mention the fact we don't know how big a black hole is we can see how big it's Event Horizon is but we don't know what black holes look like or how big they are in terms of actual space being taken up so how would we even imagine matter being Shed from them from spinning so could you be thinking of neutron stars because that is something that happens during neutron star mergers right before the merge they can sling matter from thes due to the centrifugal force but I don't see how a black hole could do that

    Maybe I’m missing something, but isn’t there a major flaw in the theory that entropy can only increase? Isn’t it disproven by star and planet formations since that’s a decrease in entropy. Dispersed elements gathering via gravity into an object width decreased entropy equivalent to the gravitational binding energy of the object. Black hole formations would also be decreases to entropy just like the factory that manufactured the metaphorical wood chipper. Galaxy formation too. If entropy can only increase, then nothing beyond random elements distributed evenly in space would be possible. We see decreases in entropy everywhere. This very KZread video is a decrease to the entropy of the universe as it’s not random arrangement of electromagnetic radiation but a very organized one which it wasn’t prior to its creation.

    You can have local systems that have a decrease in entropy, however that entropy increases outside of that system. A lot of entropy is created by the chemical reactions that go on during a planets formation, and it's following lifetime leading to a net increase in entropy. Entropy always increasing is only true as an increase across the entire universe, not in a local space within the universe.

    @@Martijm Good video and if talking about life it’s a good explanation but leaves the 2nd law of thermodynamics on extremely shaky ground when talking about galaxy, Star, and planet formation. It’s ignoring that they are a closed system by suggesting that we have to view them from a universal perspective across all time and assume that the inflationary epoch of the universe was a laminar flow of particles and that the formation of galaxies are eddies in its transition from laminar to turbulent. That’s not only highly speculative, but it’s untestable hypothesis. It also implies that the 2nd law of thermodynamics only holds up on a universal scale over all time and with specific assumptions of how the universe began. Not sure you can even call it a law at that point.

    I wondered if the speed of light is the speed it is because of at least 2 opposing forces pulling on space time .and the speed of light is how it balances out. But maybe the Forces pulling on space time are all the physical objects. If that was so the speed of light with less material would have faster speed of light and galaxies on the edge of the universe would be moving faster then light

    Well they are but it doesn't need any of that so spaceTime isn't restricted by the speed of causality so since spaceTime itself is what's expanding objects being carried along with the expansion would be completely unaffected by the speed of causality because relative to the space they are within they are just moving as they normally would but to someone with a different reference these galaxies very much are moving faster than the speed of light but that's where reference frames come in and that whole confusing aspect
