NASA Detected an ‘Anti-Universe’? Is The Signal From Antarctica Pure Hype?

Did scientists detect evidence for an Anti-Universe, one where time flows backwards? Or is it an overreach into unsupportable hype? I explore the data that led scientists to make claims about ghostly neutrinos that are their own anti-particles. How do scientists interpret data like these and how do physicists reveal the hidden symmetries of nature?

Stange signals were seen in recent years by a NASA-funded radio telescope flown aloft over Antarctica by a giant helium filled balloon. The device, called the Antarctic Impulsive Transient Antenna (ANITA), detects radio signals produced when high-energy particles coming from cosmic sources smash into earth’s atmosphere. Some radio signals waves skim the Earth before being detected by ANITA, and others reflect off the ice. ANITA can tell the difference and some claim their odd behavior are indicative of signals traveling backwards in time. Or are there other interpretatisn? Found out in this video!

The title of this video was too much clickbait for what is actually a serious and well plotted video.

"Did NASA Detect an ‘Anti-Universe’?"
No

Every time I hear about neutrinos it goes in one ear and out the other. Trillions of times.

Incredible explanation, also very interesting DESI results.

I love this idea, had a similar one 3-4 years ago. In addition to what is in the video, I also think there is a possibility...
* It's not two separate universes, both are parallel and intrinsically linked.
* It may explain where all the anti-matter went during the big bang.
* Black hole singularities become (tunnel in to) white holes in this parallel universe.
* Entropy decreases in the anti-universe universe.
* Contraction from decreasing entropy in the anti-universe could be dark energy in our universe.

and this is why She built the worm whole too!

Mothers seeing this video are going to tell their children they can't go to college to be a physicist.

Hi, I think leah broussard settled the mirror universe question during the neutron experiment she ran.
Our position as Observers makes some areas difficult to understand especially the arrow of time.
Thanks.

Soon the retrocausal pull of Roko’s Basilisk will be detected. It will be disturbing to most, but not those in the know.

Good summary but how do we illustrate also that these two 3D-t universe ends of a Big Bang are both balancing but also unreachable from each other due to growing in separation at twice the light-speed in 4D?

Nice title graphics. Now we need a fiction book series where Dr Keating breaks the laws of physics to fight crime.

I have also thought about a positron. Its unlikely to exist. But it can exist. I don't remember if its UUD or UDD that means nothing. Because it could exist does not mean it does exist. If it could be made doesn't mean it will sustain. But I do support the research into ideas. Please consider helping Idaho with education. We would love to have meteorites for our kids to see sir. Please support our public schools. Your next generation sir will be young students, it doesn't matter which state or demographic the are from. Thank you kind sir.

DR. KEATING, PLEASE BUILD A GRAVITIC DRIVE FOR FASTER THAN LIGHT SPACE TRAVEL!!!

[ericberman]

Assuming that Space-Time exists in an Anti-Universe, then time would flow backwards and the emergent effect of gravitational attraction would be replaced with gravitational repulsion hence matter would not clump and no planets, stars, galaxies, etc could/would form.

[Killer_Kovacs]

How can you tell if a point particle is move through time forwards?

[paulcasey]

Thanks Brian. Another interesting video that is accessible to the layman.

Few years back when I was kinda thnking about "missing antimatter", I figured, ok at Big Bang, matter went in our time way, and antimatter went "backwards" in time..or at least down the abcissa into "minus". What puzlled me was, if we have antimatter occurrance in "our universe" in experiments where we observed lets say positrons, wouldnt we notice causality flipped, effect before a cause in our time sequence ? That confused me. But if time antipod universe exist, it also has Gravity and I thought that that Gravity may be seeping into our universe because it might be time arrow unbound(dont ask how, didnt think it thru, have a daily job), so we observe and interpert it as "dark matter". Anyway, yea, interesting concept.

[Gldble]

I have thought this for a while. CPT symmetry would still answer baryogenesis perfectly fine if there was another, mirrored, antimatter universe going backwards in time.
Of course this means that a time-traveling particle couldn't come to us from that alternate universe, because it would have to pass through the big bang.
