When we think about symmetry, the first thing that comes to mind is mirror symmetry. Butterflies, Rorschach tests, and classically attractive faces all look the same when flipped left-to-right. In physics, a symmetry is when the laws of physics are unchanged due to some transformation of coordinates. We’ve seen examples where it is - the universe is symmetric to coordinate shifts in space, time, and even the rather abstract phase of the wave function. So it might be surprising to learn that with all the weird ways in which the universe IS symmetric, it’s NOT entirely symmetric under this most intuitive one. The laws of physics work differently in the universe of the mirror.

For the first time ever, I feel like I actually understand LESS after watching a Space-Time video than before I watched it.

@aelolul 5 лет назад

I think this episode was hosted Mirror-Matt from the Mirror Universe. Clues: 1. 0:31 Mirror-Matt says "left to right" but the diagrams fill in right to left. 2. 2:09 A left hand is shown, but at 2:16 Mirror-Matt says, "It looks like your right hand becomes your left." 3. 4:11 "clockwise spin" - yet the ball has left-handed spin. 4. The transformations of the cobalt atom starting at 9:24 ultimately put the party-transformed atom on the left side of the screen. But at 9:48, the atom on the left is labeled "normal", and the original atom is labeled "mirror universe". 5. 12:20 "A mirror-reflected Space Time" mmhmm On the other hand, the zipper on his pants would be on the same side as the regular universe, so I dunno. Maybe the weak force has an influence on how men's pants can be manufactured.

Everyone just gave me a blank look and said they had no idea when they stopped understanding but everyone also agreed that and the end of the presentation, very few people still understood what he was discussing.

What would happen if "mirror matter" was deposited into the current universe we live in? Would mirror matter bosons interact with regular matter and vice versa? If a planet of mirror matter were to collide with earth what would happen, seeing that the both planet's mass would be subject to the effects of gravity but not the other forces ( if bosons of either parity don't interact with the opposite parity matter).

@garethdean6382 5 лет назад

Well in most cases mirror matter IS regular matter. The Higgs field causes a merging of left and right handed particles. So our regular electron is made of the merger between 'lelectrons' and 'relectrons' (Both massless particles) to give a massive particle with no fixed helicity. (This makes sense, if you move slower than an electron is move in one direction, if you move faster then relative to you it moves in the opposite direction, but its rotation will be the same, reversing its helicity.) There are few exceptions such as neutrinos but the mixing caused by the Higgs field essentially prevents much mirrorstuff from ever having any effect.

@graphite2786 5 лет назад

@@garethdean6382 Thank you! I've been delving into mirror matter and there is quite a bit of contradiction with the information I've found. Some papers infer that mirror matter will only interact via gravity and that it could be a viable candidate for dark matter. Others say mirror matter may manifest itself as negative energy and be a candidate for dark energy. Then there's mirror anti-matter which is another weird and complicated concept of its own. The mirror planet scenario was something I heard on an old podcast where a couple of physicists talked about a hypothetical mirror matter asteroid entering the solar system and how it could pass through Earth and we'd never know except for a couple of strange measurements and odd phenomena. I don't think I will ever get clarity on the stuff as I'm not a quantum physicist or even very skilled in math so I rely on popular experts to fill me in, which I was hoping this PBS channel could do.

But... In the mirror we are witnessing an antimatter universe moving forward in time with us. So a mirror isn't just a parity reflection, it's a charge inversion. If what we see in the mirror could touch us we would explode. Symmetrically. Or have I got this completely upside down?

@lunkel8108 5 лет назад

1. This is irrelevant, parity is a well defined thing independent of mirrors. 2.How exactly are mirrors supposed to switch charge?

@garethdean6382 5 лет назад

No, mirror refelection doesn't turn matter into antimatter. As the video notes, time and matter-antiamtter mirroring are linked; if you reverse time you get a flip to antimatter. But if you look in the mirror you don't see time running backwards, so antimatter is also nowhere to be found.

@n-da-bunka2650 5 лет назад

Great episode. A bit tougher to follow than most* but able to absorb most during a second viewing. Looking forward to CPT symmetry episode. * Time reversal concept in the mirror universe has me thinking THAT may be a connection to dark matter so it's in our universe whose energy/gravity is the opposite of normal so it generates a pushing action. I would think that this may also logically mean that time is reversed in areas where dark energy exists. So, in theory, dark matter may simply be mirror universe components within our observable existing... space time.

@WernerEdgar 5 лет назад

Here's a completely unsubstantiated extrapolation on this: the big bang created 2 universes with different directions of time for matter & anti-matter or at least with different ratio's as the flow of time is split at the start. Explaining the existence of matter. Yes yes, I know this isn't just a leap, but also a contrived interpretation.

@guytheincognito4186 5 лет назад

That's very interesting. Also while their time would go in revere relative to ours, their time goes forwards from their perspective. However if we had a functional time machine here and then teleported it into their universe, the machine wouldn't function at all, as one Technicaly could only travel to the past but since the flow of our past goes the same as their future then it cannot function as if it were to work, that would completely fuck with the mechanics of time as we know it. Now if time machines were two way like in fiction then there wouldn't be a problem.

@WernerEdgar 5 лет назад

@@guytheincognito4186 Cool idea. But then again, if such a time machine existed we would be antimatter in the mirror universe (possibly?), immediately being annihilated without some special Sci-Fi protection. Unsure what our experience of time would be like though... ok I am hurting my head right now. ;)

Hah, for some reason this just makes my day. Go Isaac!
