What If the Comet Is Watching Us? 3I/ATLAS, Alien Theories, and the Tech That Tracks It

Only this time, the speculation is louder and more aggressive. And with it comes a familiar name and an old question wrapped in a new body: 

Is it watching us?

The Harvard Hypothesis: Loeb Sounds the Alarm Again

Dr. Avi Loeb, Harvard physicist, headline magnet, and perennial thorn in the side of the establishment, has returned with another theory. Along with Adam Crowl and Adam Hibberd, Loeb recently published a preprint paper suggesting 3I/ATLAS may not be natural at all.

His case isn’t entirely based on whimsy. He points to several peculiarities:

• The trajectory is suspiciously well-aligned with the plane of our solar system.
• The object has made calculated close approaches to Venus, Mars, and Jupiter, suggesting a reconnaissance pattern.
• Despite its bright coma, 3I/ATLAS exhibits low signs of actual outgassing, making its glow more challenging to explain using standard comet physics.
• Its closest point to the Sun occurs when Earth is hidden behind it, a moment that could hypothetically allow an unobserved course change.

Now, to be fair, Loeb isn’t claiming little green men are steering this thing. However, he is urging the scientific community to stop assuming that every rock from beyond is just that, a rock. 

Especially one that behaves as if it knows the floor plan.

The Scientific Consensus Remains Firm

For all the intrigue, the vast majority of astronomers disagree. Strongly.

They say the evidence, while interesting, still falls within the bounds of natural behavior for a long-period comet. It’s not uncommon for objects formed in the deep interstellar cold to exhibit unusual signatures when they fly closer to our Sun.

While it’s true 3I/ATLAS doesn’t appear to be outgassing like Halley’s Comet on the Fourth of July, neither did ʻOumuamua. Considering every climate model, these anomalies may reveal more about the limitations of our models than they do about the presence of advanced technology. 

Scientists tracking 3I/ATLAS with the Vera Rubin Observatory estimate the object could be nearly 7 to 12.5 miles across, making it the biggest interstellar object ever detected. And they expect it to continue behaving like a rock on a hyperbolic cruise through our system. No turns, braking, or signals.

Still, it hasn’t stopped any speculation. And deep down, you understand why.

Humor at the Edge of the Void

Let’s say Loeb is right.

Let’s say 3I/ATLAS isn’t a frozen relic but a cleverly disguised instrument. If that’s true, the aliens might want to fire their design department. This isn’t the sleek silver saucer from every UFO sighting in Nevada or Hollywood. It’s not even shaped like a cube or a probe; it's kind of a big smudge, a dust-coated blip, wrapped like a cosmic lint ball.

If its creators wanted to scare us, they could’ve made it glow red and play Flight of the Valkyrie. Instead, it’s loping through space like a lost bowling ball with a dead battery. And, if it is spying on us, heaven help them—it's not catching us looking our best. Between TikTok, tribal politics, and the decay of Western civilization in real time, they’re probably regretting the fuel spent getting here.

Still, the question isn’t absurd: It’s important because the real story isn’t whether the thing is artificial; the story is how we’d even be able to tell.

How Scientists Detect Unnatural Behavior

If you’re not fluent in astrophysics, don’t worry. Most of this can be broken down without equations. The process boils down to this: observe what the object does and compare it to what rocks and comets are expected to do; any deviation becomes a red flag.

Here’s how they look for it:

• Trajectory Without Cause: Every natural object in space follows known physical laws. It speeds up as it falls toward gravity, and slows down when climbing away from it. If 3I/ATLAS suddenly speeds up, turns, or changes orbit without anything pushing it, scientists take notice. With ʻOumuamua, a strange acceleration was observed, though never fully explained. If 3I/ATLAS pulls a similar trick, it will be watched even closer.
• Light Behavior: Telescopes don’t just see the object. They see how light reflects off it. If it flashes in a regular pattern, that might indicate spinning panels or a symmetrical shape. Natural rocks tumble erratically. Artificial objects tend to rotate predictably. That’s the difference between a coin flipped into the air and a top spinning on purpose.
• Radio Silence or Signal: SETI (Search for Extraterrestrial Intelligence) and other radio observatories sweep objects for signals, not just noise, but patterns, or narrow-band emissions that nature doesn’t tend to create. So far, both 'Oumuamua and 3I/ATLAS have yielded no results. Silence doesn’t confirm innocence, but it weakens the alien theory.
• Radar and Shape: When objects come close enough, we bounce radar off them. If the echo shows something smooth, symmetrical, or shaped like a machine, the theory shifts. So far, 3I/ATLAS looks fuzzy, like a blob of lint that hitched a ride on gravity’s coattails.

What We’re Doing Now

Astronomers around the world, using telescopes from the James Webb Space Telescope to the Hubble and ground-based scopes, are training their lenses on 3I/ATLAS. The object comes closest to its closest point to the sun in late October; unfortunately, it will be on the other side of the sun. But, in December, it will be closer and much clearer.

The eggheads will look for course changes while studying the coma and tail. Any unexpected behavior will trigger our planet's early warning sirens, arming the laser cannon platforms in geosynchronous orbit with a hair trigger. Or, more likely, they'll simply let us know if something strange happens.

We've improved our instruments where they're good enough, along with an imagination that's cautious enough, giving us an opportunity to ask better questions: Even if most of them end up having the same answer: It's just a rock.

Final Thoughts

We're not sure about what 3I/ATLAS is, but we do know one thing: It's not from around here.

It could be a messenger from a long time ago in a galaxy far, far away...

Or not.

Odds are it's a time capsule of star formation and icy voids, left behind by a forgotten traveler knocked loose by a cosmic collision.

Or maybe, just maybe, it may be something else entirely, something with billions of miles on its speedometer, not by accident, but by intent.

Unlikely? Yes! Laughable? Schmaybe.

Why? Because sometimes the most significant scientific breakthroughs begin with heresy. Sometimes, the answer is stranger than fiction.

Time will tell, right? But, if it turns left at the corner ...

We'll know.
