If time flows from future to past in an anti matter universe, do beings and things in this universe start advanced and slowly degrade?
I don't see any reason for a universe to be noticeably different if the proportions of matter and anti matter in our early universe had turned out to be the opposite way. The issue comes in when matter and anti matter come together, not in what they are, so if anti matter had dominated in the way that matter has, bfd. I think the real question is: Why did matter come into such monumental dominance?
Such an anti matter universe would consist of neutrons, protons and electrons just like this universe. A universe of Trumpists would be composed entirely of morons.
Trump didn't write it. It was published then... written by someone lost to antiquity... like the author of "Why did the chicken cross the road?" That electrons, protons, neutrons and morons comment is older than 8 track tape players.
I wasn't claiming that Trump wrote it, I was claiming that it would not have been said about "Trumpists" in 1967 since Trump was only 21 at the time. And just because it's an old joke doesn't mean it isn't true.
Hey! What do you say to a liberal in a three piece suit? ANS: "Will the defendant please rise?" Hey... you seem to like old jokes....
From what I've read about it, time appears to be advancing normally within both universes. Only, from our perspective, they appear to exist in our past, and, from their perspective, we exist in their past.
But when the past becomes the future in the anti-matter universe, does the normal advance of time within this universe get distorted, i.e., does it slow down or speed up? And if time does, indeed, distort... does Daylight Saving Apply? In the anti-matter universe does "normal" time change to Mountain Time as altitude changes?
Okay, so their future is even farther back in our past than it started as and time is going farther back still with every passing moment in our universe. The reverse is also true from their perspective. Our future is even farther back in their past. Think of it as two moving walkways in the airport, or such, each going in the opposite direction. So, you're on it and if you stand still you're moving in one direction. While someone on a moving walkway besides you is moving in the other direction. The arrow of time flows in two directions. And, whichever side of the double universes you end up in determines your perspective of what is past, present, and future.
Which is all irrelevant if you don't know where to get off the slideway to get a beer and some shrimp.
You mean like this guy? https://www.justice.gov/usao-cdca/p...ilty-concealing-facts-and-lying-investigators
A wild new theory suggests there may be another "anti-universe," running backward in time prior to the Big Bang. https://www.livescience.com/mirror-universe-explains-dark-matter
Actually no, as best as I understand it, Star Trek TAS stories aside. From their perspective our universe would be running backwards. Development would still be the same. The question is, assuming that we could enter such a universe without causing a matter/anti-matter explosion, would we retain our frame of time flow and view them as running backwards (and they us), or would we align to the flow of time there and move in that direction.
If you get a chance, read Bearing An Hourglass, by Piers Anthony, he made an interesting take on how different universes are created and end. Basically each universe starts from a Big Bang and then spreads out. "Space" is way more vast than the space each universe takes up. Eventually they spread out far enough they are too disperse to be a universe. However, matter from several universes converge on each other and form into the next "core" a Big Bang. It's an interesting concept and quite plausible IMO. I even find the above as pictured to be plausible, especially when taking into account time as a dimension the same length, width and depth.
I searched antimatter once on google and it said antimatter doesn't exist. Meanwhile tell that to all the people getting pet scans or positron emission tomography. A positron contacts an electron causing each to annihilate each other creating two photons detected by the detector creating an image. Positron Emission Tomography.
Doesn't exist in large quantities is what they probably meant. Positron is just a little anti-electron and can be emitted using radioisotopes of regular matter. Significant amounts of anti-matter would combine with matter to make an explosion more powerful per gram than a nuke.
I’ve drawn an illustration of what an anti-matter universe looks like and included it directly below. Hope that clears things up!
It would depend on how you define "per gram" Nuclear power generates power in two ways. Fission, in which an atom of a heavier element is made unstable and splits into two other elements. The two elements, together, have a smaller mass than the original element. That mass is converted into energy. Fusion takes two lighter elements and fuses them into a single element larger element. That larger element has less mass than the two original elements combined. The mass is converted into energy. Matter/Antimatter annihilation is where a piece of matter combines with the equivalent piece of anti matter and both are completely converted into energy. The mass that makes them up is what is converted. ALL mass to energy conversion is governed by the same formula Energy = mass times the speed of light squared (E=MC^2). So it doesn't matter what the process is, any matter converted to energy results in the exact same amount of energy per unit of mass. BUT, in the case of fission and fusion the overwhelming amount of mass remains as mass, only a very small part is converted to energy where in Matter/Antimatter the ENTIRE mass is converted. So if I have a gram of uranium and a gram of matter/antimatter....the amount of energy released the matter/antimatter conversion is greater only because a greater amount of mass is converted. If I had enough uranium to allow fission to convert one gram to energy, the amount of energy would be same as one gram of matter/antimatter.
