This would be a very satisfying resolution to Fermi's question.

Sounds weird! We should learn something interesting.

Do they expect heterogeniety in the distribution across solar systems then?

(That are bound to the sun)

To your first point, then is it fair to say the size distribution of comets that approach our inner solar system would appear to be an interesting anomaly?

Doesn't Loeb et. al.'s calculation wrt non-gravitational acceleration sufficiently show it must be a lower limit?

5km still seems like an interesting statistical anomaly, no? I don't think persuasive enough to claim it's artificial but it certainly seems odd.

Any non-gravitational acceleration?

Could the GSSR provide a measurement?

There was no evidence there was any actual gas associated with the acceleration.

The emotional reactions do detract from any science messaging. It's off-putting.

What about Oumuamua though? It didn't look anything like a comet (minus non-gravitational acceleration) and he was instantly slammed for making a case that it could be artificial. That case seems reasonable and unresolved but was only met with derision from establishment.

Also are you aware of anyone requesting GBT to look at the object like they did for 1I/Oumuamua? I mean, why not give it a listen?

Part of it seems like intentional trolling. He seemingly wants people sufficiently annoyed with him thinking about ways to disprove him in order for everyone to better understand the parameter space and to motivate them to improve their ability to collect data.

Let's assume Loeb is correct and it is a massive 50km object or whatever. Could that be enough to perturb something along its trajectory enough to be measurable? Eg. Some Martian moon or whatever?

Won't we be able to infer something about its mass based on gravity's effect on its trajectory?

I don't anticipate much new activity happening within our viewing windows around perihelion assuming it's natural or derelict.

It seems we're going to need optical resolution of ISOs that pass within 3 AU and are on the order of at least 100m in diameter or we aren't going to make much progress on the space trash question.

JWST data is the best we're going to get and it doesn't provide a conclusive answer. Confirmation that it's artificial would require abrupt course correction or detection of some clearly artificial EM signals. I guess it's not interesting enough to point GBT at it?

So the options are (1) it's an artificial object or (2) it's the most unusual comet we've ever seen?
