only a matter of time…
I watched a Youtube clip recently that mentioned there’s a theorised ‘island of stability’ in transuranic elements around atomic number 160. These ultra-heavy elements would be happy to exist without decaying into lighter elements. It mentioned the asteroid 33 Polyhymnia as a possible Compact Ultra Dense Object because measurements show its average density to be about three times higher than osmium.
Almost in passing, the presenter mentioned that the explosion of a CUDO entering the atmosphere above Tunguska would produce the effect we see.
Hmm, interesting. But the guy in the video doesn’t speak a lot about the criticism of this theorem:
https://en.wikipedia.org/wiki/33_Polyhymnia
For example, the 68 km (42 mi)-diameter asteroid 675 Ludmilla was originally measured to have a density of 73.99±15.05 g/cm3 in Carry’s study,[5] but improved orbit calculations in 2019 showed that it had a much lower density of 3.99±1.94 g/cm3.[14]
So there is another meteor, which was estimated the same way at the same time as 33 Polyhymnia, and they measured again later and they found it was 20 times less dense…
While it sounds like an interesting theorem this doesn’t shine a good light on it. It’s also strange that he “forgot” to mention this in the video.

He does say that the measurements need to be confirmed, but it’s way at the end of the video.
Yes, I watched the video, but he didn’t mentioned that there was already a similar meteor where they already remeasured. It lowered a bit my expectations after I looked this up.
I blame the Romulans
Says russia. Since they lie about everything you know the story is bullshit
The explosion registered at seismic stations across Eurasia, and air waves from the blast were detected in Germany, Denmark, Croatia, and the United Kingdom – and as far away as Batavia, Dutch East Indies, and Washington, D.C.
Or what do you think, which part of the story is not true? The explosion happened that’s sure, and the size should be at that range. In 1908 there were not much ways to make an explosion this big, we are well before nuclear bombs.
The largest ever artificial non-nuclear explosion was the Halifax explosion, with 2.9 kt energy. 2 huge ships collided, one full of explosives. Tunguska event had around 12 MEGAtons of energy, so around tenthousand times more. There is no way it was caused by humans. https://en.wikipedia.org/wiki/Largest_artificial_non-nuclear_explosions#Largest_accidental_artificial_non-nuclear_explosions_by_magnitude
https://en.wikipedia.org/wiki/Genetic_fallacy Have a read dunce.
So in other words you’re a massive racist. Got it.
I’m pretty sure that’s actually you in this scenario.
Wrong. Learn to read moron.
I bet reading is hard for you Elon fan boys.
Bad troll
I must confess, I have a bit of a thing for trolls - but they need to start with a base of intelligence and/or humour. So yeah, bad troll.
