Tara Shears - Antimatter: Why the anti-world matters

Ғылым және технология

Antimatter, an identical, oppositely charged version of normal matter, is one of the most mysterious substances in the Universe and very little of it survives today. Tara Shears examines the progress being made towards understanding this elusive version of matter, and explains the latest results from LHCb and elsewhere.

    The Lord Jesus Christ died for your sins, was buried and rose from the dead on the 3rd day according to the scriptures (The Gospel 1 Corinthians 15:1-4). If you believe in your heart that God rose Jesus Christ from the dead and confess with your mouth Jesus Christ is The Lord you will be saved (Romans 10) Go to a quiet place and ask the Lord to save you and forgive you from your sins - Believe on Jesus Christ and call out to Him before it's too late

    @Samwisegamgee The Brave This verbal "typo" jumped out at me as well. She DID say "electron" and then erroneously said its antiparticle was a proton. Positrons are the simplest example of antimatter, and she got it wrong, - off to a bad start. A non-trivial mistake. At that point, only people already familiar with the subject matter understand what's being said, while anyone new to the topic and trying to learn is immediately lost, without knowing it. Well when you are up in front of a room giving a talk it is easy to make simple mistakes - no problem. I think this verbal typo should be acknowledged as the first thing in the text below the video, and in a little on-screen text "woops" note when she says it, like many other videos do. Sure everyone makes mistakes, and the best thing to do is explain them right away. That way, beginners get the right information, and experienced people are saved from stopping the video to comment, possibly then moving on and finding something else to do besides watch it anymore. OK I gotta go get a PET scan now. Kidding. If you get the joke you probably caught the error too. It makes me feel smart that I remember high-school physics! :)

There are no guarantees in science --there are probabilities ranging from exceedingly high and then on down the line. Scientists challenge one another all the time.

    Science talks too much & then it accuses religion of doing the same. No matter what we think about we have to speak about, & then it is carried out. The scientists get together & talk about an idea from the latest equations; however, it takes some one less gifted in mind that must carry out the idea by building the machines the scientists speak about & then publish their ideas that are made to do the things that scientists usually don't do; I.e. the hard labor. This creates an indirect link with the scientist that led to creating the atomic bomb by Oppenheimer to the utter astonishment of Einstein that Oppenheimer seized to sadly destroy populations rather than employ them. Apathy is the cause of any misinterpretation because it is diametrically opposed to real empathy, a trait that science still really lacks. Science is matter over minds while Reality is minds over matter. Uncle Matter & Anti Matter must choose wisely always!

    Personally, I think it's all relative. The 'matter' results from the equations describe 'matter' moving relative to 'space'. The 'anti-matter' results from the equations describe 'space' moving relative to 'matter'. This would explain the 'mirrored' description of anti-matter, and why we can't find it. I think it's a bit like describing the flow of electricity from two perspectives - Negative electrons flowing in one direction, or Positive 'holes' flowing in the other. But I'm just a rookie at this stuff, and don't really know how to read the more complex equations, so I probably don't have a clue what I'm talking about...

    I don't believe the anti-electron is a proton, as she stated. Perhaps it's a verbal typo, but the positron is the anti-electron. Not the same, even though charge seems to be close to the same. A positron would have a mass at least 1000 times less than a proton.

    Tara is such a wonderful speaker and presenter. Easy flow of ideas, logical progression, and extremely clear! One aspect that seems overlooked (or maybe I missed it) is that if the LHC (large hadron collider) occasionally produces antimatter particles of some kind, does that mean that the (nominal) protons which were accelerated were actually antimatter-antiprotons? Or is it implicit that the collision itself somehow occasionally produces antimatter?

The annihilation of the matter-antimatter pair occurs when the "matter" particle falls into the "hole" that we perceive as the antiparticle. The gap between the two is 2 x mc^2 (1 mc^2 for the particle and the other for the depth of the hole), and that is how much mass is annihilated and energy radiated away.

    A whole bunch of very sophisticated arguments... Interdimensional influencing and whatnot. Quantum entanglement being possibly correlated with gravity and the higgs, and why that is on a meta scale... Mostly numbers we can't quite calculate yet. Pretty controversial stuff. There are many physicists right now that can't seem to agree. But that's pretty normal according to what I have read.
