“3I/ATLAS Just VANISHED From NASA’s Radar Is More TERRIFYING Than ‘Oumuamua’ Ever Was” | Michio Kaku​

Astronomers are sounding the alarm after interstellar object 3I/ATLAS suddenly vanished from NASA’s radar systems — and experts say this could be even more mysterious and alarming than ‘Oumuamua’. The object, first spotted moving at incredible speeds through our solar system, has now disappeared without a trace.

Dr. Michio Kaku and other top physicists are now questioning what’s really happening out there in the deep void. Was 3I/ATLAS just a comet — or something far more advanced than we can understand? Some new data suggests it may have changed trajectory… on its own.

This could change how we understand interstellar visitors forever — and raise new questions about what’s truly passing through our solar system.

Avi Loeb: 3I/ATLAS Sent a Signal in 1977 (99% Chance) | Science for Sleep

What if a famous signal from the past wasn't random noise, but a deliberate message from a passing visitor? In this bedtime exploration of cosmic mysteries, we follow Avi Loeb's striking hypothesis about 3I/ATLAS—the interstellar object that may have sent humanity a transmission decades before we ever knew it existed. From the iconic 1977 detection to the mathematics of impossible timing, we'll drift between radio whispers and orbital mechanics, exploring how an object from beyond our solar system could have called out to us long before its arrival.

Why does the thought of an earlier contact change everything? What does it mean when the timeline of discovery gets rewritten by a wandering messenger? Tonight, we lean into the improbable, tracing the threads of signal analysis, cosmic coincidence, and the audacious questions that connect us across time and space.

This is sleepy science for cosmic dreamers: gentle musings on messages, probability, and the imagination's restless pull toward contact. Perfect for those who want to drift off with interstellar puzzles close at hand, who find comfort in the unknown, and who let wonder guide them toward sleep.

If this tale of signals and certainty has stirred your night, consider liking and subscribing for more science told in starlight. Here's to quiet minds, endless skies, and the wonder of what reaches out across the void.WiederholenClaude kann Fehler machen. Bitte überprüfen Sie die Antworten.

Seeing as how NASA is closed because of the gov shutdown, there isn't any way to verify the claims.

NEWEST COMET ATLAS OBSERVATIONS

The comet is exactly where it is supposed to be. It has NOT sped up or slowed down - no non-gravitational acceleration.

Why did you hear otherwise? They straight up lied. It's perfectly where it is supposed to be.

ALL anomalous chemistry and EM/ED tail signatures are due to it being the most electronegative comet ever seen, which is not shocking given that it came from somewhere else.

It's a comet.

So much BS related to this comet. Avi Loeb is an AH, I guess he wants attention.

3I/ATLAS: Harvard Expert Avi Loeb Reveals 'Alien Ship' Has Seven Thrusters Near Sun​

 
Ah, the plot thickens…

Astronomers Have Found a New Object Flying Between Comet 3I/Atlas and Earth
LADbible

Astronomers have recently found yet another thing floating about, and this too, doesn’t have the tell-tale tail of a comet. Moving between 3IATLAS and Earth with no tail, the ‘comet’ was found to be 105,078,392.0 kilometres away from Earth, or 0.7024056659 Astronomical Units, which is about five and a half months away.

Its closest approach to Earth is thought to occur on 11 November 2025, when it passes at about 103 million kilometers away from us.

Same as what happened in 2011 with comet Elenin. Morons called it an Extinction Level Event due to it's first 3 letters being E L E.

Takes a very special kind, I guess. lol


Problem is, there are fear mongers out there pushing this shit for laughs when people who don't, or won't even try to know better, eat it up like it's leftover Halloween candy.
.....and then tell all their friends.

That smells like MSM lies to me. There is no such thing as "perfect" in science. It's all probabilistic and everything has an estimate of error included.

"Perfect", in the sense that it's currently where it was predicted to now be.

Just not necessarily "perfect", to the centimeter.

THE STORM IS NOT OVER: Last night's severe (G4) geomagnetic storm is subsiding, but the action is not over. Earth's magnetic field is still reverberating from a double-strike of CMEs on Nov. 11th. A third CME is expected to hit Earth on Nov. 12th, elevating storm levels back to G3/G4. If you missed the auroras last night, you might get another chance. Aurora alerts: SMS Text.
DOUBLE CME STRIKE PRODUCES SEVERE STORM: Arriving earlier than expected, two CMEs struck Earth on Nov. 11th. The closely-spaced sequence of impacts produced a severe (G4) geomagnetic storm. Auroras spread across almost every US state with sightings as far south as Florida, California, Texas, Arizona and Alabama.
"These are possibly the brightest auroras I’ve ever seen," reports Benjamin Root, who sends this photo from Atkins, Iowa:

Good thing it was moving transverse. If it would have been headed right for Earth we'd never seen it.
 
I saw many Auroras when I grew up in farm country Idaho. But here in snowflake city the light pollution is so bad I cannot even see stars most nights. Even when it stops raining for a day or two. But anyhow, here's the latest on 3I-ATLAS:

12 anomalies concerning 3I/ATLAS:
Medium
  1. Its retrograde trajectory is aligned to within 5 degrees with the ecliptic plane of the planets around the Sun, with a likelihood of 0.2%.
  2. During July and August as well as in early November of 2025, it displayed a sunward jet (anti-tail) that is not an optical illusion from geometric perspective, unlike familiar comets.
  3. Its nucleus is about a million times more massive than 1I/`Oumuamua and a thousand times more massive than 2I/Borisov, while moving faster than both, altogether with a likelihood of less than 0.1%.
  4. Its arrival time was fine-tuned to bring it within tens of millions of kilometers from Mars, Venus and Jupiter and be unobservable from Earth at perihelion, with a likelihood of 0.005%.
  5. Its gas plume contains much more nickel than iron (as found in industrially-produced nickel alloys) and a nickel to cyanide ratio that is orders of magnitude larger than that of all known comets, including 2I/Borisov, with a likelihood below 1%.
  6. Its gas plume contains only 4% water by mass, a primary constituent of familiar comets.
  7. It shows extreme negative polarization, unprecedented for all known comets, including 2I/Borisov, with a likelihood below 1%.
  8. It arrived from a direction coincident with the radio “Wow! Signal” to within 9 degrees, with a likelihood of 0.6%.
  9. Near perihelion, it brightened faster than any known comet and was bluer than the Sun.
  10. It exhibits sunward and anti-solar jets which require an unreasonably large surface area in order to absorb enough sunlight needed to sublimate enough ice to feed the mass flux of these jets.
  11. Near perihelion it exhibits non-gravitational acceleration which requires massive evaporation of at least 13% of its mass (as calculated here), whereas preliminary images indicate that the object maintained its integrity and did not break up.
  12. Its tightly-collimated jets maintain orientation across a million kilometers in multiple directions relative to the Sun despite its measured rotation.
 
This thread is morphing into something I can't take part in.
