A Decade of Discoveries at the Large Hadron Collider
Ғылым және технология
It’s been 10 years since the first particles smashed into each other at the world’s biggest scientific experiment, the Large Hadron Collider. Scientists from each of the four giant experiments - ALICE, ATLAS, CMS and LHCb - reflect on what they've learned over the past decade and what they hope to discover in the next.

The astrological "signs" (Libra, Pisces, etc.) could be more legitimately associated with the Lunar orbit as our Moons gravitational pull changes on a nearly monthly basis due to its angle (position) in the sky. The seasonal angle of the Suns gravitational effects could be factored in as well, but only if it's proven that the effects on our brains circuitry is profound enough to cause shifts in behavior patterns. Predictability should be proven accurate with repeatability measurements based on a calendar year cycle.

I would love to see an electron. WHAT! You don't have one. You mean you cannot show me the teny tiny little BB;s flowing back and forth in the wires above my head. Trillions of dollars laundered and many generations of paychecks for the bean counters. But yet, not even a picture of an electron. Some great graphics and a dinosaur this time. WOW! How many times can you rip the people off. This one has got to break some kind of record. “To describe an electron as a negatively charged body is equivalent to saying that it is an expanding-contracting particle. There is no such condition in nature as a negative charge, nor are there negatively charged particles. Charge and discharge are opposite conditions, as filling and emptying, or compressing and expanding are opposite conditions.” - W. Russell JJ Thomson developed the “Ether Atom” ideas of M. Faraday into his “Electronic Corpuscle”, this indivisible unit. One corpuscle terminates on one Faradic tube of force, and this quantifies as one Coulomb. This corpuscle is not and electron, it is a constituent of what today is known incorrectly as an “electron”. (Thomson relates 1000 corpuscles per electron) In this view, that taken by W. Crookes, J.J. Thomson, and N. Tesla, the cathode ray is not electrons, but in actuality corpuscles of the Ether.” - E. Dollard “There is no rest mass to an ‘electron’. It is given here the ‘electron’ is no more than a broken loose “hold fast” under the grip of the tensions within the dielectric lines of force. They are the broken ends of the split in half package of spaghetti. Obviously this reasoning is not welcome in the realm of Einstein’s Theory of Relativity.” - E. Dollard “Unfortunately to a large extent in dealing with dielectric fields the prehistoric conception of the electro-static charge, the ‘electron’, on the conductor still exists, and by its use destroys the analogy between the two components of the electric field, the magnetic and dielectric. This makes the consideration of dielectric fields unnecessarily complicated” - C.P. Steinmetz (Electric Discharges, Waves and Impulses) The idea of electricity as a flow of ‘electrons’ in a conductor was regarded by Oliver Heaviside as “a psychosis”. This encouraged Heaviside to begin a series of writings Also consider the J.J. Thomson concept of the "electron" (his own discovery). Thomson considered the electron the terminal end of one unit line of dielectric induction.

@@markdavich5829 Wrong, gravity is a constant force. Don't be mistaken by thinking because the water has waves that gravity is propagated through wave form. Gravitational waves are literal ripples in the fabric of spacetime. So you can have tides in water without "gravity waves." Think of a half full bottle of water in your hand. Your friend grabs at the bottle, pulls it toward themselves a bit but you're far stronger. This is an application of an opposing force, but because of your strength being greater you still retain the bottle in your hand. You then look at the water and notice the persistence of little waves on the surface. The force was not applied in waveform yet waves continue to propagate within the bottle. In essence the Earth is a big bottle and the moon is your bottle grabbing friend .

Just a question: 5:50 I'm currently at a temperature much higher than -270C and I'm in the Universe. Is it correct to assume that the temperature of the universe mentioned by the researcher is an average? If it is an average, is it really possible to say the LHC is the coldest place in the Universe? Thanks! (So, this is a real question - it started with a rather lame observation but then my brain told me I know almost nothing and that I should check with the specialists ... and that's what I'm doing.)
@maxwellpruner2168
3 жыл бұрын
The -270C (~2.73K) figure is indeed an average, based on measurements of the cosmic microwave background. Press release by ESA in 2003 shows the Boomerang Nebula measured -272C (1K), and other experiments on earth have created temperatures much closer to absolute 0K, albeit for short periods of time. Perhaps more accurate measurements have been generated recently though, making the presenter's statement accurate. I'm by no means the specialist you seek.

I am still astounded by what some humans can do when they work together (such as engineering / science projects like this). The human race should hold these people in the highest possible regards and do away with old fashioned beliefs in deities for which there is no actual evidence (books written by people that came after the rumoured events - a hundred years from now are they all going to believe that the events in the Da Vinci code actually happened because it was written down etc). Sorry if this causes offence to anyone - it is not meant to, but it is important to discuss areas like this.

Yeah basically they are hoping against hope to save their precious supersymmetry despite failing to create these these supposed particles (even though they have run out of the solutions that would actually fit existing problems) Of course there is a difference between upgrading an existing collider and building a new more energetic one because they *hope* something unexpected will pop out. Given that there are two possible candidates of dark matter that are part of the standard model that seem to have more experimental support than any hypothetical supersymmetric particle ever has. Pretty much all of the failed dark matter searches have looked at these supersymmetric WIMPs and alternatives have only recently have been explored even the ones directly implied to exist by observations of deviations from the standard model such as Neutrino's having mass or the theta value parameter in QCD(Quantum Chromodynamics) being inexplicably zero. It kind of floors me that they haven't exhausted candidates within the theory before rushing all focus towards super symmetric solutions due to the so called apparent "WIMP miracle" In general once you are adding the mathematical equivalent of extra epicycles to your extra epicycles to match observations that continue to produce over a decade of continuous null results it is probably time to look elsewhere... >_> This is where Sabine is a breath of fresh air needed among particle physics.

Nothing after Higgs though. These physicists are in a true existential crisis now. They are even debating the requirement of "elegance" in their formulations. Nobody in the field knows where to go now. Had to come back to say that the only direction physicists can go now is to pursue higher energy collisions. This means the cost of the next collider they will ask for will make the LHC look like the price tag of a dollhouse in comparison. Came back again to mention the notion of Naturalness as these particle physicists see the term. Ask your buddy the meaning of that term and then ask what it has to do with the scientific method. Then run, because they are likely to throw something at you.

As over 100 nations are involved in this publicly funded group of experiments, your comment was remarkably incoherent and ridiculous. Who's queen? No one national leader calls the shots for anything at the LHC. And what would be a potential motive for suppressing anything? It would benefit them enormously to release any interesting bit of information immediately as it justifies further funding and support. Suppression of science benefits nobody, least of all very expensive international projects like the LHC. Finally, the sheer number of competing nations involved ensures that if suppression of information somehow benefitted one nation it would likely not benefit their competitor, resulting in the exposure of any attempted suppression, and that is IF politics somehow infected those teams of international scientists at all. Thus, at no level does anything you said make a shred of sense.
