UM-Bot Posted July 4, 2019 #1 Share Posted July 4, 2019 Scientists are attempting to prove the existence of parallel universes by firing neutrons at a solid wall. https://www.unexplained-mysteries.com/news/328837/experiment-seeks-evidence-of-mirror-universe 3 Link to comment Share on other sites More sharing options...
zep73 Posted July 4, 2019 #2 Share Posted July 4, 2019 Quote The experiment itself will involve firing a beam of neutrons at a solid wall with a neutron detector set up at the other side. Normally the detector should pick up nothing at all because the neutrons cannot pass through the wall, however scientists believe that some of them may temporarily "oscillate" in to a mirror universe and back, enabling them to pass through the wall where the detector will pick them up. Whether the experiment will succeed in detecting anything at all however remains to be seen. My money is on "a waste of time". If they succeed, I will be in shock! 3 Link to comment Share on other sites More sharing options...

zep73 Posted July 4, 2019 #4 Share Posted July 4, 2019 How can they be sure that a neutron passing the wall is not just quantum tunneling? @cormac mac airt @danydandan @Harte You guys should be able to answer that, right? 3 Link to comment Share on other sites More sharing options...

From the energy level of the captured neutron, I would say. Harte 4 Link to comment Share on other sites More sharing options...

AFAIK Quantum tunnelling generally applies to levels of particles well BELOW the threshold of the atomic particles of proton, neutron or electron and entering the realm of fermions, bosons, etc. The question would tend to be on the level of "why can't a car travel through a mole-hole?". cormac 1 2 Link to comment Share on other sites More sharing options...
Seti42 Posted July 4, 2019 #7 Share Posted July 4, 2019 Just finished Stranger Things season 3. I'd recommend against searching for a mirror universe, lol. 1 2 Link to comment Share on other sites More sharing options...
zep73 Posted July 4, 2019 #8 Share Posted July 4, 2019 I did a Q&A with experts on another forum. Here's a summary: A: The stuff about parallel universes and "portals" is hyperbole. Q: So it will not prove parallel universes, even if they succeed? A: Certainly not parallel universes. But if it provides evidence of mirror matter then it is possible (but not certain) that there could be large scale structures equivalent to stars and galaxies, made up of mirror matter. This would exist in our universe but not be directly detectable. That could be described as a "parallel universe" but it requires a bit of journalistic license. There is a good overview of mirror matter here: https://en.wikipedia.org/wiki/Mirror_matter Q: Isn't that just supersymmetry? A: Not quite. There are multiple symmetries. Some lead to anti-matter, others to supersymmetric particles, others to mirror matter. (There may be others ...) So, people, this is not something that could reveal parallel universes!! 3 1 Link to comment Share on other sites More sharing options...
Grim Reaper 6 Posted July 5, 2019 #9 Share Posted July 5, 2019 Now I understand why the US Government scrapped the Neutron Bomb after they test fired the weapon. Link to comment Share on other sites More sharing options...
Harte Posted July 5, 2019 #10 Share Posted July 5, 2019 Protons, neutrons and electrons all exhibit quantum tunneling under certain circumstances. IIRC, protons and neutrons must be at a much lower energy state than is necessary for an electron. Electron tunneling is common. Without it, the Sun doesn't work. Or so I read several years ago.

zep73 Posted August 13, 2019 #12 Share Posted August 13, 2019 I found a good video explaining this stuff. Hope it helps those who feel a little lost trying to understand it Link to comment Share on other sites More sharing options...
