> That for sure is triggering folks who take themselves very seriously. I don't think anyone in the field is triggered by some guy pursuing his interest in aliens and UFO. What they get triggered about, is that guy using his relatively large platform to say that anyone not agreeing with him is part of the establishment or otherwise useless, or to say that there is no other possible explanation to a certain phenomenon…
> to be insulting to another colleague during an online talk. When did this happen? In the podcasts and interviews I heard, Loeb was often provocative towards the establishment, but I never saw him make negative comments about an individual.
Last year [1].
To be fair to him, he did apologize [2].

#153"It's not a philosophical question whether we live in an environment where objects are flawed. Around that are representing extraterrestrial technologies."
I can't make sense of these sentences. And the spelling mistakes are helping either.
"Today [Galileo Galilei] would have been canceled on social media."
For what exactly? And his this guy not seen the quality of social media commentary? The bar is loooow. Spectacular but unfounded claims are a mundanity and it's worrying that he's mixing these culture warrior talking points with science.
"Once I realized that we found an object from a technological origin that was produced elsewhere."
Unfounded spectacular claims just like this. The object is interstellar maybe, but where has he shown evidence of a technological origin? This is pretty important. How is it just left unchallenged?
It's a weird article. The video looks like a shot from The Thunderbirds and it reads like something from a local station affiliate run twice through translation software.

The payload: " Based on the CNEOS catalog of bolide events, we identify the ∼0.45m meteor detected at 2014-01-08 17:05:34 UTC as originating from an unbound hyperbolic orbit with 99.999\% confidence. The U.S. Department of Defense has since verified that "the velocity estimate reported to NASA is sufficiently accurate to indicate an interstellar trajecto…
It's not just the orbit that's unbound and hyperbolic.

#155I think I've seen this movie before; just don't let anybody touch the strange Sphere thing and you should be alright. Seriously though, this doesn't make much sense to me. Finding shipwrecks even when you know they exist and what general area they should be in is hard enough. This sort of search is a huge money sink, the ships, towed sonars, etc all cost a ton of money to operate.

To be fair, if you're not going to Google it, you're probably more of a popular media reader anyway. There are no pictures in the paper to look at. https://arxiv.org/abs/1904.07224
Did google and didn't find it. Maybe my Google fu just isn't as advanced as yours. Then again, why not just include the link?
It turns out the key here is to use "Abraham" not "Avi" in the search. The latter returns crapola and the former yields your link a few hits down.
Don't worry about lack of pictures (there actually are some figures), I'm pretty good at this English thing. Turns out the object was quite small:
> Given the impact speed of the meteor, ∼ 44.8 km s−1, and the total impact energy, 4.6 × 1018 ergs, the meteor mass was approximately 4.6 × 105 g. Assuming bulk density values of 1.7 g/cm3 and 0.9 g/cm3 for Type II and Type IIIa objects respectively, we obtain a radius, R, of 0.4m – 0.5m for a spherical geometry (Ceplecha 1988; Palotai et al. 2018).
The small size of the object was something the article didn't address.

Isn't it sort of funny that they think the asteroid might be some new material, or at least something tougher than iron, yet they are planning to use a magnet to pull up pieces? What happens if it's non-ferrous...
Using a magnet seems like not a top 5 idea someone would have.
Say you find the asteroid on bottom of ocean. What sort of hoisting apparatus do you propose we use to bring it ashore?

Or just a chunk of titanium. It's only made in novas and supernovas so having an abnormal trajectory, and speed only supports the theory. A bunch of titanium slapped onto some rock and then later breaks off or something.
My understanding is that anything heavier than iron is made by supernovae, so the same could be said of the majority of elements.

#159> Using data from government censors Should be "sensors" (used correctly a few sentences later). Is this a text-to-speech thing, or written by a non-native speaker, or just appalling editing? > Once I realized that we found an object from a technological origin that was produced elsewhere. Difficulty to having parse.
This article lists 3 authors and is riddled with basic grammar and spelling problems. One can only imagine what factual errors it contains.

Right, but titanium is stronger than steel, let alone iron.
>When compared to steel in a strength-to-weight ratio, titanium is far superior, as it is as strong as steel but 45% lighter. In fact, titanium has the highest strength-to-weight ratio of all known metals.
There's a reason cherry picked titanium. :)
