god it looks delicious

2022 update

Here is where we get to the new (and, as yet, unpublished) work. Our Sun isn’t the most common type of star; cooler M-type stars are much more common. M stars are more favorable environments for the creation of worlds covered in nitrogen ice. In our solar system, you have to be nearly at the orbit of Neptune, at 15 a.u., for nitrogen ice to be stable on the surface. However, stars at the lower end of the mass range (technically classified as M8) can host worlds with nitrogen ice at only 1 a.u.

Taking into account the huge population of M stars and their more favorable environments for hosting nitrogen ice, Desch and Jackson found that M stars will have ejected 40 times more nitrogen ice fragments than stars like our Sun.

That contrast is enough for `Oumuamua’s appearance in our backyard to be a likely accident. Its trajectory, which lies in the galactic plane and has relatively low speed for an interstellar interloper, indicates that it hasn’t been roaming the galaxy on its own for very long; it probably exited its parent solar system up to a few hundred million years ago.

it hasn’t been roaming the galaxy on its own for very long... up to a few hundred million years ago.

astronomers have funny ideas about time

the James Webb Space Telescope discovers enormous distant galaxies that SHOULD NOT EXIST

in conclusion the universe is so effing big it is yielding contradictory data to stupid little confused lifeforms

it's too big!

Why does anything exist? did they answer that one yet? seems a bit improbable that anything does exist tbh.

I assume you're looking for a better answer than "slight difference between the amounts of matter and antimatter generated by the Big Bang"?

:(

A team of researchers from the UC Berkeley and Cornell found a surprisingly simple explanation for ʻOumuamua's non-gravitational acceleration:https://t.co/qvMNSECL3A

for non-twitter-havers it reads "A team of researchers from the UC Berkeley and Cornell found a surprisingly simple explanation for ʻOumuamua's non-gravitational acceleration" and links to this: https://www.universal-sci.com/article/cause-of-oumuamuas-non-gravitational-acceleration

that surprisingly simple explanation in full:

oumuamua was fart-propelled

as are we all

mostly you tho

i am as god made me, sir (a small object estimated to be between 100 and 1,000 metres (300 and 3,000 ft) long, with its width and thickness both estimated between 35 and 167 metres (115 and 548 ft))

I for one welcome Amaterasu, "one of the highest-energy cosmic rays ever detected".

https://www.theguardian.com/science/2023/nov/24/amaterasu-extremely-high-energy-particle-detected-falling-to-earth

This article was amended on 24 November 2023 to clarify some of the wording, based on agency copy, that was used in an earlier version regarding the speed of particles.

that copy:

Some charged particles in the air shower travel faster than the speed of light, producing a type of electromagnetic radiation that can be detected by specialised instruments.

idk maybe it's technically correct (mutters something about group velocity or c in a vacuum)

The Amaterasu particle has an energy exceeding 240 exa-electron volts (EeV), millions of times more than particles produced in the Large Hadron Collider, the most powerful accelerator ever built, and equivalent to the energy of a golf ball travelling at 95mph.

I would not want to be in its way, but a 95mph golf ball does not seem that cosmically terrifying?

what if that golf ball actually went through your brain?

"In September 2011, it was reported, in a major release by CERN, that a tau neutrino had traveled faster than the speed of light; however, later updates from CERN on the OPERA experiment indicate that the faster-than-light readings were due to a faulty element of the experiment's fibre optic timing system.[12]"

it aint over till…

there he is (avi so-called loeb)

bring back oumuamua
