m4n8tpr8b replied to the thread Roasting marshmallow' exoplanet is so hot, it rains metal. How did it form?.The article says that the study determined the ratio of rocky matter to icy gaseous matter, so I wondered whether, on one hand, the loss... -
m4n8tpr8b reacted to George²'s post in the thread When is an asteroid not an asteroid? When it's Elon Musk's Tesla Roadster, it turns out. with
Like.
I've read articles about this and I'm not convinced that this is a discovery of a new form of magnetism. It's probably just that... -
m4n8tpr8b replied to the thread How much did SpaceX's Starship Flight 7 explosion pollute the atmosphere?.All the commenters protesting bias but not reading the article properly show their own bias. Scare mongering? This is reporting on...

m4n8tpr8b replied to the thread Hubble tension is now in our cosmic backyard, sending cosmology into crisis.You clearly did not understand anything I wrote, in spite of what you call "teaching babytalk", and it appears you have no idea what...

m4n8tpr8b replied to the thread When is an asteroid not an asteroid? When it's Elon Musk's Tesla Roadster, it turns out..What the article doesn't say is indicated by the asteroid designation: the "discovery" was based on a new identification in old (2018)...

m4n8tpr8b replied to the thread Hubble tension is now in our cosmic backyard, sending cosmology into crisis.Currently, the extrapolation forwards is accelerating expansion forever, but the exact details depend on factors we don't know enough...

m4n8tpr8b replied to the thread Astronomers discover 196-foot asteroid with 1-in-83 chance of hitting Earth in 2032.You're waaaaaaay behind the news, like 20 years and one month behind. The chance for a 20 December 2029 impact of Aphophis was predicted...

m4n8tpr8b replied to the thread Astronomers discover 196-foot asteroid with 1-in-83 chance of hitting Earth in 2032.Good observation. For 2024 YR4, NASA currently also considers impacts in 2039, 2043, 2047 & 2074, all with very low probability due to...

m4n8tpr8b replied to the thread Hubble tension is now in our cosmic backyard, sending cosmology into crisis.Nope. You still think of space as some independent ethereal background (within which the Big Bang was an explosion), instead of...

m4n8tpr8b replied to the thread Hubble tension is now in our cosmic backyard, sending cosmology into crisis.You start from a good foundation but go off in some bad direction. You correctly say that time is a fourth dimension orthogonal to the...

m4n8tpr8b replied to the thread Hubble tension is now in our cosmic backyard, sending cosmology into crisis.The other commenter was wrong, using CMB is not a "direct" measurement, either, there is no such thing. It is a comparison of the scale...

m4n8tpr8b reacted to Torbjorn Larsson's post in the thread Hubble tension is now in our cosmic backyard, sending cosmology into crisis with Like.
Cosmological redshift is not a Doppler shift, and no physicist has claimed that in a century, I think. But is caused by photons being...

m4n8tpr8b replied to the thread Astronomers discover 196-foot asteroid with 1-in-83 chance of hitting Earth in 2032.2024 YR4 first got the attention of astronomers on December 30, when the impact risk was estimated at about a tenth of the current...

m4n8tpr8b replied to the thread Hubble tension is now in our cosmic backyard, sending cosmology into crisis.To have a perspective on this, it is worth to remember that this is not the first time we have Hubble tension. Throughout the 1990s, the...

m4n8tpr8b replied to the thread China plans to deflect an asteroid by 2030 to showcase Earth protection skills.Obviously, the energy (or moment) needed to deflect an object is proportional to its mass, and the more time we have, the more energy...
