Not sure if this is news or not, and it maybe out of date. I saw a recent news article about the James Web telescope capturing images of distance galaxies that were thought to be small primordial ones. But the images are showing the galaxies to be far larger than expected which would indicate that they are much older than first assumed. Based on this it would indicate that the universe is much older than currently described. However, the scale of the galaxies in the images could be misleading due to gravitational lensing, thus giving the appearance that they are much larger than they actually are. Not 100% sure how this is determined but it is suggested that th…

Shiny bright objects are not always what they seem to be. "A shape-shifting robot that looks like a cross between a Lego figure and the T-1000 from Terminator 2 has been filmed melting itself to escape through the bars of a miniature jail cell." https://www.bbc.com/news/av/world-us-canada-64668021

I found the following article on the BBC news science website The Antarctic and Arctic sounds rarely heard before https://www.bbc.co.uk/news/science-environment-64514258 With reference to this." a seal that sounds like it is in space". Is this me, or does this just sound sloppy. As far as i am aware sounds don't travel through the vacuum of space. Also to make such a comparison we would need a proper frame of reference to compare the sound to, e,g an actual seal in space I do understand the other comparisons "Singing" ice, and a seismic airgun thundering like a bomb . As for example the latter would be on earth anyway, and ice cracks and creaks too.…

Dark energy ‘chameleon trap’ wins £100,000 prize for Nottingham scientist

Archaeologists have confirmed that a papyrus scroll discovered at the Saqquara necropolis site near Cairo last year does indeed contain texts from the Egyptian Book of the Dead— the first time a complete papyrus has been found in a century, according to Mostafa Waziri, secretary-general of the Supreme Council of Antiquities in Egypt. The scroll has been dubbed the "Waziri papyrus." It is currently being translated into Arabic. https://arstechnica.com/science/2023/01/archaeologists-discovered-a-new-papyrus-of-egyptian-book-of-the-dead/ These "books" were actually collections of funerary texts and spells to help the deceased on their journey through the underworld…

Closer To Truth has a new website, which I think is quite well made, visually appealing, and features all the high-quality content the channel is known for. I highly recommend it: https://closertotruth.com

Interesting paper from back in July (how did I miss this?), co-authored by Giorgio Immirzi, one of the foremost experts on GR and quantum gravity: https://arxiv.org/abs/2207.04279 This is just the latest paper within an increasingly large body of work that indicates that ‘dark matter’ as a separate phenomenon may be entirely superfluous. The basic idea here is that, under certain specific circumstances, even in the weak-field and low velocity regime, there may be non-negligible GR effects that aren’t found in Newtonian gravity. Hence, sometimes Newtonian gravity is not a valid approximation to GR in the weak field domain - which is the very assumption from which…

https://www.quantamagazine.org/asymmetry-detected-in-the-distribution-of-galaxies-20221205/ https://arxiv.org/abs/2206.03625 Now this is very interesting! Despite the 7-sigma significance mentioned in the paper, this will of course require further corroboration. But if this turns out to be a real thing, then it would have far-reaching consequences. Definitely one to watch!

https://www.quantamagazine.org/does-time-really-flow-new-clues-come-from-a-century-old-approach-to-math-20200407/ (This is a pull-quote, but I have to warn that reading the full article may be necessary to follow what Gisin is up to. I can't cut/paste everything on this device, sorry.) Over the past year, the Swiss physicist Nicolas Gisin has published four papers that attempt to dispel the fog surrounding time in physics. As Gisin sees it, the problem all along has been mathematical. Gisin argues that time in general and the time we call the present are easily expressed in a century-old mathematical language called “intuitionist mathematics,” which rejects the…

This certainly sounds like a big deal: https://www.nature.com/articles/d41586-022-03820-3 5 papers published so far on it: References Rustamkulov, Z. et al.

https://www.nature.com/articles/d41586-022-04201-6 "Did physicists create a wormhole in a quantum computer?" I was wondering what anyone here makes of this latest news as published today in Nature? Did they just simulate the transfer of information or did it really happen (both?) How might this affect the search for a theory of quantum gravity?

Space chiefs are to investigate whether electricity could be beamed wirelessly from space into millions of homes. The European Space Agency will this week likely approve a three-year study to see if having huge solar farms in space could work and be cost effective. The eventual aim is to have giant satellites in orbit, each able to generate the same amount of electricity as a power station. ESA's governing council is to consider the idea at its Paris HQ on Tuesday. While several organisations and other space agencies have looked into the idea, the so-called Solaris initiative would be the first to lay the ground for a practical plan to develop a space-…

Just as with other climate changes where there are feedback effects, we need to watch closely and determine what all the effects might be. https://www.theguardian.com/environment/2022/nov/17/microbes-melting-glaciers-bacteria-ecosystems Hundreds of thousands of tonnes of bacteria are being released by melting glaciers, a study has shown. The microbes being washed downstream could fertilise ecosystems, the researchers said, but needed to be much better studied to identify any potential pathogens. The scientists said the rapid melting of the ice by the climate crisis meant the glaciers and the unique microbial ecosystems they harboured were “dy…

Nice comparison image of the two telescopes together. The improvement is definitely noticeable.
