Mars is just 0.107 of the Earth mass. Who needs this loser? Belt: 2.8 AU Earth: 1 AU. Mars: 1.5 AU min(Mars-Belt) = 2.8-1.5 AU = 1.3 AU, 0.107/1.32 ~= 0.063 max(Earth-Belt) = 2.8+1 AU = 3.8 AU, 1/3.82 ~= 0.069 So, the Earth affects the belteroids stronger than Mars even when Mars is at the closest distance, while the Earth is at the fartherst one.

JoeSchmuckatelli Posted June 16, 2022 Author Share Posted June 16, 2022 Star formation not always inhibited by massive neighbors: https://www.reuters.com/lifestyle/science/tarantula-nebula-stunning-view-stars-being-born-2022-06-15/ "... we always thought that when massive stars - over 100 times more massive than the sun - begin to form they release so much energy that it prevents the infall of more gas, shutting off the fuel for more stars to form. The beautiful observations of the Tarantula Nebula obtained with ALMA now show that where the gas is dense enough it continues to fall unabated and new stars can keep forming" Quote Link to comment Share on other sites More sharing options...
DDE Posted June 16, 2022 Share Posted June 16, 2022 On 5/20/2022 at 9:06 PM, Autochrome said: This "scientific" news article implies that the moon is tidally locked to the Sun and only one side gets light and the other one is in complete darkness. I assume he got it from the misnomer "dark side of the Moon", even when each side of the Moon receives the same amount of sunlight over the course of a month. Reveal hidden contents So when we talk about a "day" on the moon, it's important to remember that one side of the moon -- the "dark side" -- never gets struck by sunlight. There's not going to be any sunrises or sunsets on the moon, ever. How do we measure a day on the moon, then? This is why such a simple question as "how long is a day on the moon?" is far more complicated than you might expect. Even when I was six I knew that the Moon is tidally locked to the Earth, not the Sun. One Russian-language science news Twitter account (@PowerNaShary) once wrote: "Elon Musk has promised to deliver Earthlings to Mars in six years. Some think his ideas are madness, but that's unless you realize that it's vitally important humanity bugs out from this olanet before our sun turns into a black hole. Which is 100% going to happen." Spoiler "Is our sun different from Mars's one?" "That's why there are people like Steve Jobs, Bill Gates or Elon Musk, and there are such people as Dmitry Rogozin.

And got the impression that whatever the FRB is may be orbiting / coorbiting the persistent radio source, which could, with further study, help elucidate what is the FRB source. I also like the inclusion of the collaborative telescopes' images along with the radio data! Quote Link to comment Share on other sites More sharing options...

They are procedurally generated. Some seed values give similar results. Check and mate, creationists!

steve9728 Posted June 21, 2022 Share Posted June 21, 2022 (edited) Don't know can this related to the science news but I think is really cool: I'm not in China right now and few months ago my parents said that the 'Government Reserve Sites' (it was the waste land with nearly 1m tall grass) diagonally across the road from my home, was built a primary school using the prefabricated container modules. From a literally wasteland to children babbling in their classrooms in just six months. Yesterday I was curious to try to search how was it looks like inside and I got this: https://www.bilibili.com/video/BV1X64y1h7PF?spm_id_from=333.880.my_history.page.click&vd_source=6fef304b8d0c4737896e6b702ddfbfb3 Fast foward to 02:41.

Question: I've seen numerous reports that in a lot of places the rapidly built stuff is also rapidly degrading stuff (water leaks, crumbling concrete, fascia/cladding falling off in sheets - I'm not talking about the criminally negligent stuff, like bridge & building collapses, but rather the 'lipstick on a pig' thing where it looks good initially but then the problems start to emerge shortly after occupation - mold, water leaking, wall paper bubbling, tiles falling off that kind of thing). What kind of domestic response is there to the safety issues and loss of value to purchasers/users of buildings that should see decades of utility becoming degraded in 3-5 years? Are there consumer protections for folks who buy a lipsticked pig? Quote Link to comment Share on other sites More sharing options...

Are there consumer protections for folks who buy a lipsticked pig? I've never been in a building like this myself, so I don't think I'm qualified to say what the experience was like inside. But just down the road from my home, on the other side, another traditional reinforced concrete primary school is being built. If my estimates are correct both school gates are estimated to be no more than 300 metres. I think this school in the video should be built quickly for short term to cater for the children in the surrounding area. Mold, leaking things actually I also quite curious how they fix it: there is a sub-tropical coast city which means we got rainy season in spring to summer that easily make everything mildwed and many typhoons in summer. There is a local TV interview with the head of the school and the engineer who built the primary school. The engineer said that the panels used inside are prefabricated panels called 'cabin panels' (or litral directly translate to 'ship cabin panels') which I think are supposed to be of aluminium construction. "There is no paint, no benzene, xylene or other toxic or harmful fumes in those panels.", said by the engineer. The vice-principal of the school said in an interview that he had "obtained data from a third-party company to test the indoor air quality of the school before moving in, and that he had communicated fully with parents before moving in". This video definatly won't have any English substitle but it have some clips on how it was built: https://weibo.com/1789681642/JwB9SxQLm?refer_flag=1001030103_ Edited June 21, 2022 by steve9728 Quote Link to comment Share on other sites More sharing options...
