What's the truth about antigravity?

Antigravity is a key part of many science fiction and UFO reports, but it’s an idea that is potentially scientifically reputable and scientists at CERN, Fermilab’s sister laboratory, are investigating possible connections between antimatter and antigravity. In this video, Fermilab’s Dr. Don Lincoln covers both the fact and fiction of this interesting topic.

My favorite t-shirt says "I read a book on Antigravity and couldn't put it down!"

My favourite quote that I only get to share once a year: "Ah, April 1st: the only day of the year where people think critically about what the read and see on the Internet before believing it as true."

4:45 making anti-electrons or anti-protons is pretty easy...
8:16 antimatter is outrageously hard to make...
Hard to make and store in macro quantities.

My mother told me that when she was in grade school they taught her that it would be impossible to fly to the moon because by the time you loaded an airplane with enough fuel and supplies, you couldn't get it off the ground.

If someone actually DID have an antigravity device, they could probably use it to make WAY more than a million euros.

Please do a video explaining how the "tic tacs" on the Pentagon videos of UAP are capable of their movement.

It doesn’t add anything to the discussion but for the sake of YouTube algorithms I will comment: brilliant video! Thank you as always 🙏🏻

When my daughter was very young, the first time she saw a helium balloon she asked, "fall up?"

[TheGreatest]

In January 1989 I saw a disc float over my cottage in Scotland. It was going very slowly and there was nothing holding it up. It was also very low- only about 60 feet up. It was making a low humming sound, it had a series of circular red lights around the base facing downwards. There was no wind from it, it had no wings, no jets, no rotors, nothing. It should have fallen out of the sky. Whatever was keeping it up, wasn’t ‘silly’ but very effective, and very real.

I'm really glad Dr. Lincoln was able to understand my explaining this to him.

[noahway]

The current Dr Don robot is learning, and acting more natural with more fluid movements. It still has a long way to go to seem real.

"What goes up must come down.". Nope, not true. Once you hit 11km/s you ain't ever coming down- ever.

I don’t think this representative from fermi lab did his home work with regards to the the published papers published by NASA Physicist at Univ of Alabama—> Ning Li, who’s papers claimed a practical way to Produce anti-gravity effects (1991, 1993) creating down “gravitomagnetic field perpendicular to their spin axis.” She wrote “if a large number of ions could be aligned, (in a Bose-Einstein condensate) the resulting effect would be a very strong gravitomagnetic field producing a strong repulsive force.” The alignment may be possible by trapping superconductive ions in a lattice structure in a high-temperature superconducting disc. Her claim of having functional anti-gravity devices was cited by the popular press and in popular science magazines with some enthusiasm at the time. “In 1997 Li published a paper stating that recent exponents reported anomalous weight changes 0.05-2.1% for a test mass suspended above a rotating superconductor. Although the same paper describes another experiment that showed the gravitational effect on a non rotating superconductor was very small, if any effect existed at all.” —>very cool. Your big Black T-shirt and cheeses little video cut pieces from old flying saucer movies —-> marks you a defender of Huburis. You should not be allowed to represent Femi Lab, please sit down.

Never underestimate the unknown, Fermilab. Once in a while it is precisely someone from this peculiar group of freethinkers who paves the way for a new invention. So a little more respect please for the freethinkers among us.

[iStormUK]

I subscribed so long ago, Don had just got his PhD, been hooked ever since. ;)
Seriously though, my days are happier now you're back in person :D

[marthinusdawidvanrooyen]

"Making anitmatter is pretty easy" What a time to be alive.

[felipelopes]

Hi Dr. Don, isn't there also an argument that antimatter should fall down because of CPT symmetry? It would be a striking result if it falls up.
