@politipet.piaille.fr.ap.brid.gy No, I haven't actively promoted it or asked others. I just made an effort to follow bridged users when I stumble upon them. There was a starter-pack here on #bsky for bridged scientists I'll try and find again.

Sounds good -- like email, that's a good analogy. @politipet.piaille.fr.ap.brid.gy

So, good etiquette with bridged users is to always include the name? @politipet.piaille.fr.ap.brid.gy

I'm a big fan of all efforts to integrate #bsky into the wider federated ecosystem. Keep up the good work. :)

I use @bossett.social's profile labeller and definitely notice an uptick in bridges users liking my posts or following. Your activity seems to have triggered some automated science related feeds to pick up my posts on other servers too.

Is there an easy way to find my mirrored profile? I assume you're on one of the mastodon servers.

No problem. ๐

The Yucatan is well inside the North American plate and not near the boundary. Though such impacts likely lead to increased global earthquakes and volcanism temporarily. Regardless, the sinkholes and gravity anomaly are all features of the crust which move with the rest of the plate.

No, because the crater is part of the plate itself which as a whole moves under plate tectonics. With that said, evidence suggests the initial crater punched down to the base of the crust to near the mantle boundary. www.sciencedirect.com/science/arti...

I should probably include the #Physics โ๏ธ feed too since Nobel Prize winner Luis Alvarez, a physicist, is who popularized the impactor theory. Btw, they have a cool little display about the Chicxulub crater next to his old office at Berkeley.

I was 1/3 before, now I'm 3/3. :) Thanks Altmetric.

Using the like/heart on a post like this feels uncomfortable.

Nice list! I added a bunch of folks to my feed from it. ๐ฅณ

Tbf, while Pluto was rightly "demoted," the IAU definition of planet isn't great considering how squishy the "clearing your neighborhood" condition is. Ultimately planet is a fuzzy taxonomy as the universe contains a myriad of edge cases that defy easy categorization. And that's cool!

One possibility I like which is mentioned in the article is that the neutrino was potentially cosmogenic in origin from the scattering of another ultra-high energy cosmic ray (say a proton) scattering off a CMB photon. Such collisions are predicted by the GZK limit.

Excellent work. What's the equipment details?

Most of the mass in these filament structures is indeed dark matter, but we can see them because of the light from the ionized gas that overlaps the filaments between the quasars.

Yeah, I'm still learning how to process the files better.

Not where I'm currently living, but when I was in Tucson, Arizona, it would be perfectly doable.

The tidal forces still happens even without the Earth's oceans. The effect is just more obvious on a liquid. The most important part is the size, mass, and orbits/rotation of each body.
comment in response to
post
The tides on Earth (which also slow down our rotation) is because of the influence of the Moon on us. However, the Earth's effect on the Moon was much stronger and the Moon is now in a permanent "high tide" always facing us one way.
comment in response to
post
Only the Moon is tidally locked to us therefore only showing one face at all times. For other planets, we just see them rotate.
comment in response to
post
The Moon does indeed have a center-of-mass anomaly, but its not responsible. Optical libration happens because the axis of rotation of the Moon is not exactly synchronized with its orbital plane. Also our vantage point on the surface of the Earth relative to the Moon depends on the time of day.

To clarify, I did NOT make this, I would like to do this in the future. ๐
