[@jamieclarke2694]

I'm wondering if the strong nuclear force broke away causing inflation because there was no actual mass at that point, then the Higgs field came about and stopped or massively slowed down inflation incredibly quickly because now all the energy used by the inflatron was being inserted into the universe using the Higgs Field to create mass, which instantaneously slowed down space that was expanding faster than light because spacetime now contained actual mass that gravity acted on and was pulling space back. Then as spacetime expands further and further and the universe cools, there is enough empty space to speed up expansion again and the space to matter ratio increased enough for the higgs field, matter and gravity to stop slowing it down as much. Or space is negative matter and therefore always pushes away the opposite of gravity. Or the super hot plasma and energy at the beginning pushed actual spacetime outwards until it cooled and couldn't push outwards anymore, describing inflation, then later empty space is dark energy as negative gravity and that's why you get the filaments, gravity pulling matter in and empty space pushing it out. Or.... I need to go to bed for a few years and think about what I said without any physics or mathematical knowledge, trying to pretend I understand anything about this amazing awe-inspiring universe we are blessed to live in!

I appreciate the human emphasis you put on the contributions of physics' more unsung heroes. I never knew about Galois, these obscure stories are what initially drew me to physics not the math lol. I'm a writer and like all story-tellers, I want to live forever through my stories but I find myself wishing more and more I was a physicist instead. The universe doesn't care about your though process, what makes sense to you or your world view/beliefs, it is what it is and it rewards those who look deeper and ask it questions, regardless who they are or where they are from. Its sad Noether, Wu and so many others never got the recognition (Nobel's) they deserved. But, I also think its beautiful that even without a Nobel when we talk of symmetries and forces with our new alien friends its the likes of Noether, Wu and their work that will be humanities ambassadors, why? Because the universe truly is symmetric where as our ideals might fall short. If you find an underlying truth about reality the universe itself will reward your efforts and deepen your understanding for it even if it takes the rest of the world while to catch up with you (think of Pauli, "I have done a terrible thing, postulated a particle that cannot be detected.) So thank you, truly your content is special! nothing else like it wish you and your team all the best you guys genuinely make KZbin better just by existing. Understanding how and why a conclusion was reached is equally important as that conclusion so again, Thanks guys for making me fall in love with the stories behind the numbers. Without them they'd just be some quirky numbers scientists are fussy about and i probably wouldn't care.

[@owfan4134]

I'm sure you are doing just as great and impactful a labor as the writers and story-tellers behind this video. It's just as you say; who cares about fussy scientists bickering about quirky numbers in journals stocked to the brim with academic jargon? The answer, of course, is that these are the closest things to objective truths we can arrive at in the field of natural philosophy. Group theory, among the likes of Darwin's theory of evolution, was one of many pivotal innovations in mathematical thinking which underpinned the rocket-launch of natural philosophy into the modern world from the stone and bronze ages of Platonic theory and Aristotelian discourse. I'm sure Pythagoras would've been among the bustling crowd ecstatic to witness the spectacle of the 3,000 ton controlled explosion that was the scientific revolution and it's now precipitously accelerating payload. Meta-mathematics is probably a better descriptor for it, because the definition of the conservation of momentum being mutually inter-dependent on the concept of translational symmetry indicates the connectivity and ubiquitous nature of the fundamental laws of physics; the language which describes each law is bound by logical axioms and rules which produce repeatable and universally consistent results, an artifact present in equal parts in the smallest part as much as the largest one. Whoever looks deeper and asks it questions, the universe rewards, even the hesitant and critical Pauli! Thanks for reading.

[@deusexaethera]

In reality, they would've noticed the problem as the exhaust plumes from their deceleration engines started mutually annihilating upon contact with each other, before they got anywhere near close enough to touch. Still, another excellent video. The discussion of magnetic monopoles puzzles me. I'm not sure why some physicists say they should exist, since it's already well-established that magnetic fields are generated by the _movement_ of electric charges. A monopolar field would require a static buildup of some kind of charge, in this case an electrical charge, and static charges are by definition _not_ moving.

Idk if they'd notice because of the excitement and/or pressure, but it definitely would be visible, yeah. They also probably wouldn't just disappear, just ruin their space suits and maybe their hands (or whatever the alien would use to touch)

How can you deliver the history of the universe in 48 mins? Wow. How you pulled so many people, facts, equations, experiments and theories together is incredible. Then you blow me away at 37:31 where you introduce the perfect and symmetrical "super-force" using the Bible to illustrate the point. (correction in the reference-- the verse quoted was from Gospel of John 1:1, not Genesis"). Regardless, the point is made, and I believe that Super-force was involved at the beginning, is involved today, and will be involved tomorrow as the universe expands. Thanks again for the thought provoking and super-educational video. Along with the others, I look forward to more amazing content!

i started with this video going to binge watch all ur content from the start thank u sir u are amazing

Nothing in the universe is hidden .... Unseen..unknown...incomprehensible...and every degree of unbelievable that could be .. Too small or too big...but never hidden...❤

[@innocentbystander3317]

Oh wow, you just made math so much easier for me. Never noticed a pattern of symmetry quite like that before. Looking forward to the rest of the video even more, now! Thanks.

The intro to this video is a masterpiece. So many ideas amd emotions packed into 3 minutes.

[@AndreiNeacsu]

Awesome video! Thank you! With a mismatch in the helicity of the (virtual) anti-neutrinos in neutrinoless double beta decays (should this decay modes exist), I believe that for certain proposed mechanisms you could distiguish between electron and positron one one side and anti-electron and anti-positron on the other side. Because electrons have mass, helicity is not the same as chirality. This would add another layer of complication in our understanding of the Universe, of particles and symmetries.

This channel and Cool Worlds are the dopamine of existential wonder I need to get through my life tbh.

Other than confusing Gen 1:1 with John 1:1, this video is excellent!

[@PeloquinDavid]

Yes. That gaffe really jumped out at me too... I guess I shouldn't be surprised that science-oriented KZbinrs may be unfamiliar with canonical literature of the culture they emerge from, but it does cast doubt on their interpretations of "the facts" generally...

[@zacharytuttle5618]

@David Peloquin lol "culture they emerged from"

Keep crying nerd, reminds me of how people get all butt hurt about confusing star-trek with star-wars

Thank you, this was so clearly and beautifully explained.

[@kingdomkeys-prod]

Yes you are my favorite narrator! I love that little breathless fluctuation you add for emphasis!! Bravo my dear sir!

[@KryogenKeeper]

Following the "path of least resistance" or "least action", I'm curious HOW that path is determined before hand.

[@Nick-jz9yz]

Maybe it doesn't know until it's observed? Maybe it's everywhere all at once and something something wave functions? Idk the stuff is confusing but this is a great question you have

[@KryogenKeeper]

Water streaming down a window runs into resistance, THEN adjusts it's path. Light doesn't seem to have to do this. Perhaps it does, but too quickly for us to observe?

[@magnatron007]

Another great video, although I will be watching it at least once more because I'm dumb and this is going to take a bit to wrap my mind around. The idea of finding an entire civilization made of antimatter is just mind blowing. why has no one used this idea in a scifi novel or movie I just don't know, or maybe I just missed that one somehow.

[@Compguy321]

It would definitely make for a good Star Trek episode!

Great episode! Thanks for posting!!

[@scottweidt9144]

Usually I watch this channel when I'm falling asleep. I'm watching this during the day and I'm glad I did. Very educational!

[@theblackprince1346]

More great content guys, by the way are you still making videos for history of the earth? Just feel like that channel has now become the secondary channel with less uploads than this channel.

[@HistoryoftheUniverse]

Thanks! New video coming next week, they are now coming out about once every three months so we can balance everything.

[@theblackprince1346]

@@HistoryoftheUniverse thanks for the very quick reply. Look forward to it, love all your content.

[@karlpoulin3938]

The best explanation so far on symmetry. Outstanding video, congrats!

[@jinushaun]

The opening premise would make a great full length sci-fi novel! What if the Cosmological Principle is wrong? The twist ending reminds me of the Three Body Trilogy where humanity comes to a terrifying cosmic realization.
