TTorbjorn Larsson reacted to Unclear Engineer's post in the thread Gravitational waves hint at a 'supercool' secret about the Big Bang with
Like.
I thought "supercool" phase transitions were quite rapid. At least for water that is supercooled, a disturbance of some sort seems to... -
TTorbjorn Larsson replied to the thread NASA will give a Boeing Starliner update on Aug. 27 and you can watch live.Stareliner👀. Astronauts tend to trust NASA's decisions.

TTorbjorn Larsson replied to the thread Is asteroid Psyche actually a planetary core? James Webb Space Telescope results cast doubt.Nothing, but such an element sorting in the disk is less likely, Gravitational sorting in rocky planets with metal cores is ubiquitous...
-
TTorbjorn Larsson replied to the thread Earth's 'evil twin' Venus may have mirrored our planet more than expected.Interesting formation history of the smaller of the two largest venusian tesserae regions, implying they are both craton analogs. The...

TTorbjorn Larsson replied to the thread The moon's thin atmosphere is made by constant meteorite bombardment.The proton number is the same for all isotopes of an element, but differ between elements.
-
TTorbjorn Larsson replied to the thread Newborn moon may have had many mini-siblings in Earth orbit long ago.Those are rather old results, heavily relying on massive analytical models before doing simulations (for the youngest paper), remarkably...

TTorbjorn Larsson reacted to ChrisA's post in the thread Newborn moon may have had many mini-siblings in Earth orbit long ago with Like.
Is it really so surprising that after a huge off-center collision with a Mars-size planet, there were many chunks of debris flying in...

TTorbjorn Larsson replied to the thread Venus may be able to support life, new atmospheric evidence suggests.Here is a pessimist converting to optimist under the new data...

TTorbjorn Larsson replied to the thread Saturn threw a comet out of the solar system at 6,700 mph. Here's how.The article does not explain the "how" of the title. Annoyingly, the paper reference also do not suggest a mechanism but is applying...

TTorbjorn Larsson reacted to m4n8tpr8b's post in the thread Saturn threw a comet out of the solar system at 6,700 mph. Here's how with Like.
Should be "eccentric" rather than "elliptical" (I guess a braintypo, after all, later you correctly write that the orbit is hyperbolic...

TTorbjorn Larsson replied to the thread NASA telescope may have found antimatter annihilating in possibly the biggest explosion since the Big Bang.Wow. I never thought I would see a matter-antimatter annihilation emission line! But it seems that BOAT has sailed.
-
TTorbjorn Larsson replied to the thread Could galaxy cluster collisions be used as dark matter detectors?.The method is best for one class of dark matter models, though with much larger statistics - if we can get to it - the method can see...

TTorbjorn Larsson replied to the thread If we want to settle on other planets, we’ll have to use genome editing to alter human DNA.A study looked at robotic exploration but found that humans do it faster and cheaper, assuming you invest enough money for manned...

TTorbjorn Larsson replied to the thread If we want to settle on other planets, we’ll have to use genome editing to alter human DNA.McKee is a philosopher and Rees is an astronomer, neither has a say on the use of biotechnology, and it is telling that McKee has to...

TTorbjorn Larsson replied to the thread How stars' magnetic fields could impact the chance for life on orbiting planets.Early Earth was sterile and now it is not, so the general idea has been tested. If you mean Darwin's hypothesis specifically, as Unclear...
