"Cracking up" and "So now"...(3I/ATLAS)

 



Avi Loeb Medium 11/10/25


"The sublimation of carbon dioxide (CO2) ice requires 600 Joules per gram, nearly 5 times less than the sublimation of water (H2O) ice which is 2,835 Joules per gram. The Webb telescope spectroscopic data (reported here) indicated that when 3I/ATLAS was 2.4 times farther from the Sun than its perihelion distance, 87% of the mass of gas around it was CO2. In order to supply 5 billion tons of CO2 over the perihelion passage period of a month, 3I/ATLAS must have received at least 3x10^{18} Joules to sublimate this much CO2 mass. At its perihelion distance, the Sun provided 700 Joules per square meter per second. This means that the absorbing area of 3I/ATLAS must have been larger than 1,600 square kilometers. This is the area of a sphere with a diameter of 23 kilometers, 4 times larger than the maximum diameter of 5.6 kilometers inferred for 3I/ATLAS from the imaging data of the Hubble Space telescope (reported here). The required diameter is 51 kilometers for water ice."

“Houston, we have a problem” with the natural comet hypothesis! The required surface area of 3I/ATLAS to provide the inferred mass loss from the latest post-perihelion image, is at least 16 times larger than the upper limit derived here from its Hubble image on July 21, 2025.


(Funny...I used the same exact phrase 

"Houston, we have a problem”

3I/ATLAS Bits and Pieces

"However, the object's spectroscopic data 

shows a coma rich in carbon dioxide 

and low in water, 

and it has not displayed 

the expected massive gas plume 

that would account for the acceleration."


(Opps, "Houston we have a problem.")


"When the Webb data was taken on August 6, 2025, 3I/ATLAS lost only 150 kilograms per second. The mass loss at perihelion derived above is 4 orders of magnitude larger, about 2 million kilograms per second. This is a dramatic increase, requiring a power-law dependence of mass loss on distance from the Sun with a power-law index of -10.5, consistent with the rapid perihelion brightening of 3I/ATLAS reported here."


"Was the dramatic mass loss and brightening of 3I/ATLAS at perihelion evidence that it disintegrated? Breakup into fragments would have increased the surface area of its material. Since the surface-to-mass ratio scales inversely with the characteristic radius of fragments, an increase in surface area by a minimum factor of 16 requires that 3I/ATLAS broke into at least 16 equal pieces, and likely many more. This would mean that 3I/ATLAS exploded at perihelion and we are witnessing the resulting fireworks. In other words, the latest image implies that 3I/ATLAS was decimated by heating from the Sun if it is a natural comet."


"The tidal force of the Sun is expected to separate the fragments in the coming weeks, creating an appearance similar to that of the comet Shoemaker-Levi 9 in 1994 near Jupiter. I discussed this possible outcome a month ago here."


"However, if upcoming observations were to reveal that 3I/ATLAS was not decimated by the Sun and maintained its integrity as a single body, then we will have to consider that it is something other than a natural comet."



Oh it's 

"something other than a natural comet."

alright.


Revelation 8:8-9

And the second angel sounded, and as it were a great mountain burning with fire was cast into the sea: and the third part of the sea became blood;

9 And the third part of the creatures which were in the sea, and had life, died; and the third part of the ships were destroyed.)


"there is not enough rocky material in interstellar space to accommodate the delivery of such a giant icy rock to the inner solar system over our survey period of a decade. We would expect an object with a diameter above 10 kilometers to be delivered to our vicinity once per ten thousand years or longer. This anomaly has a likelihood of less than 0.1% if all rocky materials are packaged in large bodies of 3I/ATLAS’ size or less than 0.0005% if there is equal amount of total mass per logarithmic package mass interval. Combine that with the 0.2% probability of the retrograde trajectory of 3I/ATLAS being aligned to within 5 degrees with the ecliptic plane, and you get a chance of one in a hundred million for 3I/ATLAS to originate from a familiar astrophysical origin."


(Told ya it's 

"something other than a natural comet."

alright.)


"Technological thrusters require a much smaller mass loss in order to produce the observed jets around 3I/ATLAS. Chemical rockets are propelled by an exhaust speed of 3–5 kilometers per second, which is ten times larger than the maximum ejection speed of volatiles sublimated by sunlight from natural cometary surfaces. Ion thrusters reach an even higher ejection speed of 10–50 kilometers per second. Alien-tech thrusters might employ yet higher exhaust speeds, reducing the required mass loss by several orders of magnitude and making the required fuel a small fraction of the spacecraft mass. Upcoming spectroscopic observations will determine the velocity, mass flux and composition of the jets of 3I/ATLAS. Stay curious!"


Sorry Avi

It's not a technological problem...

(3I/ATLAS)


 It's a 

laws of nature 

problem.






As the Government Shutdown Ends, 

Can NASA Please Release 

the 40-Day-Old HiRISE Images of 3I/ATLAS?

Avi Loeb Medium 11/11/25



Avi is asking for

Images of 3I/ATLAS taken 

On October 2–3, 2025,

" the HiRISE camera onboard the Mars Reconnaissance Orbiter 

took side images of 3I/ATLAS 

with 30 kilometers per pixel resolution, 

as 3I/ATLAS passed within 29 million kilometers from Mars."


First he was all about the images taken 

on Oct 3rd when 3I/ATLAS was the closest to the red planet, 

then for still unexplained reasons

he switched to images taken on Oct 2nd

AND NOW

he wants

Images of 3I/ATLAS taken 

On October 2–3, 2025

??????????


Something aint right.
