![[Q&A+] Galaxies Sticking Together, Feeling The Expansion, Flawed LCDM | Q&A 366](https://s3.castbox.fm/24/b4/04/0f219cd643e9e8f5d1428820dce8fe45f2_scaled_v1_400.jpg "[Q&A+] Galaxies Sticking Together, Feeling The Expansion, Flawed LCDM | Q&A 366")
Why didn't all galaxies stick together at the early stages of the Universe? Can we feel the spacetime expanding? What if simulating the Universe is easier than physically exploring it? And in Q&A+, why is Starship so hyped compared to other new rockets?Watch the video here (with no ads) or on YouTube: https://youtu.be/uNPZMHzXBpIHere's a link to the full unedited livestream: https://youtube.com/live/eEwAbIxFNBs
![[Interview+] Remember Hycean Worlds? Well, Looks Like They Shouldn't Exist](https://s3.castbox.fm/a3/20/91/991d417f167ebb6540379624020b3202f0_scaled_v1_400.jpg "[Interview+] Remember Hycean Worlds? Well, Looks Like They Shouldn't Exist")
Recently we heard a lot about hyaena planets. They are supposed to be sub-neptunes with thick Hydrogen atmosphere which allows them to maintain a planet-wide liquid ocean in a vast range of conditions. The most famous example of such a planet is K2-18b which was recently observed by JWST. But the latest studies and simulations show that, in fact, hycean worlds are probably much drier and thus the ocean worlds we were envisioning shouldn't exist.Watch the video here (with no ads) or at YouTube: https://youtu.be/lDAIAXQkNrg

James Webb can't resolve Earth-size planets around Sun-like stars. Not just because of the contrast but also because of the diffraction limit. To do that you need a mirror of 20+ meters. But what if you increase the size in just one direction? You get the required resolution but keep the mirror relatively small and easy to transport. This is the idea behind the Rectangular Mirror Telescope.Watch the video here (with no ads) or on YouTube: https://youtu.be/w3QXTW6DaIg
