Oumuamua is apparently red in color indicating an iron component. Certain frequencies of light and charge particles cause current flow in different metals. With current comes a flux field. Magnetic field from the sun(or other planets/stars/bodies) and or charged particles can then interact with this flux field to impart an accelleration. Certain metals can also become magnetized in which case they will be influenced by magnetic fields of other bodies i.e. planets and stars. This would likely be the case with countless other objects in the universe and could explain some other things such as the galaxy spin and eliminate the need for dark matter.

The contrast between Sagan and Loeb could not be more stark. Loeb would have done well to heed Sagan's axioms and not just the 'extraordinary claims need extraordinary evidence' one but also 'the thing you want to be true the most is the thing you need to be the most skeptical about' Loeb has always struck me as an overtly ambitious self-promoter. Thanks for taking this on.

@romangeber 2 года назад

I don't know Loeb but remember that I once stopped listening to an interview with him when he started throwing those accusations of lacking imagination and so on around after essentially babbling on about nothing of substance. Wrote him off as a bit of a nutcase who somehow made it into a podcast of interest. If it's aliens, prove it. No need to accuse anyone of anything, winner takes it all. The problem is that it's never aliens. The book isn't even on my radar but the review was certainly entertaining.

@KafshakTashtak 2 года назад

Regarding the light sail argument: One thing I have learned in the past couple of decades: A lot of things come to existence that almost no one could predict. When you look at something like Bitcoin, or Social Networks, you don't see any old sci-fi novel that had a good prediction on them. Similar story exists for when we look at even older sci-fi predictions. All of that means the stretch of our imagination cannot go very far. It only goes to the edge of our knowledge. Now when someone says some alien tech must be light sail, it's most likely because his imagination could not go further than our current knowledge. He could not imagine some other alien tech that could slowly propel a space craft. Even Faster than light traveling, or teleportation is the edge of our knowledge, based on general relativity, and quantum mechanics.

@HebaruSan 2 года назад

For another example of the limits of imagination, consider how often sci-fi aliens have alphabets and arrange their names like "first-name surname", making them less different from Western countries than China already is in real life.

@davecarsley8773 2 года назад

"Bitcoin" has nothing to do with a PhD understanding the ways that you can travel through space.

@robertoyamakata6672 Год назад

If I were Loeb, I would locate his theory as an excercise of thinking and not go behond that. In that way he would retain the best of two worlds: Being a serious Harvard astronomer and being worldwide popular as well. It's good to make questions (theories) in order to promote thinking. But to be seen hardly assuring that an allien spaceship visited our solar sistem without undeniable evidence can be bad for your reputation.

@mooferoo 2 года назад

I used to like Loeb before all this, but i realised i'd only seen him in interviews acting as a futurist rather than a scientist. Now, whenever i see him talking about "real" things, i feel intense third party embarrassment. He's a bit bonkers, and actually doesn't seem to have a sense of logic.

Oumuamua was only traveling at 0.000003% of the speed of light. Not really worth exploring the galaxy if you were an alien civilization. Only about twice the speed of the Voyager spacecrafts, for example, and we don't really think the Voyager's will ever get to another star.

@user-hu3iy9gz5j 2 года назад

Great argumentation.. but 18:20 Technically there would only have to be one single alien civilisation to explain Oumuamua as a an alien probe, not necesarelly a large number of them.

@raidermaxx2324 2 года назад

waaaait. why do you say that? The reason why there has to be a "large number of them" is because statistically and on a macro level, the universe is sooo big, that the chances that our solar system, would be the recipient of a "alien light sail bouy" are infinitley small... Thus, the higher number of technologically advanced alien civilizations, who are specificially making this type of craft(because that also factors in to the chances of us, witnessing this event) means the more probable that this has occured.. You dont see the logic? Like why do you think he said that?

Wonderful review! Dr. Sutter, was the motion speed of the solar system taken into account when observing the data of the object? I was just wondering if oumuamua approached the solar system in its directional motion and the acceleration observed on the objet's escape velocity is due to the solar system moving away at the same time. I love astronomy and physics but don't have a degree or education in those fields. Thank you.

So.... in other words: you're not as popular, open-minded, or respected as Dr. Loeb, so you have to make your bones by criticizing him on youtube and claiming his arguments mean something they don't, then debunking your own "translation" of his arguments (a.k.a. things he never even said) instead of addressing the things he's _actually_ said??? OK. Got it. Perfect example. At 18:21 You claim that professor Loeb says we need to believe that there's "a large number of alien civilizations" and that these alien civilizations "produce an astounding number of light sails".... You then "debunk" and argue against these points as if Professor Loeb has ever actually made ANY of them. Spoiler Alert: He hasn't.

@waynespringer3320 2 года назад

Sadly I thought you Dr. Sutter would be more open minded. Avi Loeb DID NOT say that IT WAS alien technology. What he did say was it had the potential to be that kind of technology which he based on the data at hand at that time. It would be an understatement to say that I am disappointed. Your only goal was to discredit an idea which is paramount to what is science. That being, keep an open mind and follow the data. Is this the new cancel culture when you dismiss out of hand someone else's data driven idea when it doesn't match your own? Sad disappointment.

@Milan_Openfeint 2 года назад

I don't think you actually watched the video. 1) Trying to disprove ideas *is* actually paramount to science. If the idea is correct, it cannot be discredited. Speculating wildly without contact with reality is not science. 2) As explained in the video, Loeb's idea is not based on data but on personal benefit. 3) On the contrary, data says Oumuamua was a natural object. At no point in time did data point to an artificial origin.

It's not looking good for the sceptics Oumuamua is one of the strangest objects we've ever seen in space, so it's worth having a closer look. I think that's Avi's point. Paul isn't interested in looking, which is fine - but he isn't interested in anything he doesn't understand - generally. Not my kind of scientist. I think the sceptics need to be a little careful with their proclamations and attacking scientists like Loeb in the current climate, Sutter and DeGrass....ect will end up looking really silly.

That makes no logical sense. There were no natural explanations for lightning, tides, the phases of the moon, hurricanes etc etc at various times in history. So people, making the same logical error that you're making, pushed for a god as explanation. Of course they were always wrong and we found natural explanations. As for "likely" - you've not even proven "possible". We don't even know if there are aliens yet alone intelligent aliens, yet alone intelligent aliens making spaceships out of rocks, yet along such aliens in spaceships that have somehow made it here. So no, you cannot say it's "likely". All you can is that there is some anomalous behaviour that was measured.
