SpaceEngine TODO

Wow, those are incredible simulations.  Surreal.  Now I dream of seeing the Earth-Theia impact rendered this way as well -- presumably much harder than for asteroids, but maybe it will be possible in the near future. :)

Cosmology Discussion Thread

K1496gv8KCo Abstract:   Planck is an ESA satellite aimed at the observation of the Cosmic Microwave Background. The Planck collaboration has recently published its last legacy release. In this talk I will shortly review the main Planck results and their robustness, highlight some of the curious fea...

31560 Hey Wats, I wouldn't mind hearing your opinion on this, as crazy as some of it sounds: Sorry for forgetting to get back to you on it.  It's a pretty good video as usual from him.  I'm not quite sure what you'd like me to talk about with it, though.  It is kind of a mashup of simple explanatio...

Astrophotography

31766 20.25 hours That is an impressive integration time, and the result looks amazing! Also (and maybe you've already considered this or have a different philosophy), it might not be a bad idea to put watermarks on your high-res images.  I'd hate to have someone easily steal and profit from your v...

Science and Astronomy Questions

31711 Quarks have an astonishingly wide range of masses. The lightest is the up quark, which is 470 times lighter than a proton. The heaviest, the t quark, is 180 times heavier than a proton -- or almost as heavy as an entire atom of lead. Oh yes, the different types of quarks have a wide range of ...

Science and Astronomy Questions

31701 One of the most fascinating and somewhat paradoxical qualities of quarks (and something which makes them quite fascinating to me) is that the mass of each individual quark is MUCH more than the mass of a proton or a neutron..... Something happens to all that extra mass when the three of them ...

31705 Far from being trivial, isn't this how most elements beyond Iron get produced?  Actually no, most elements above atomic number 40 came from colliding neutron stars rather than exploding stars. But what I mean about it not being trivial is the question of  how does the star explode?   Most peo...

31681 Is there a periodic table for antimatter and other types of atoms? Yes, but it looks exactly like the regular periodic table. :P  The chemical properties of antimatter atoms should be exactly the same as the regular matter atoms.  The antimatter particles themselves have the same properties a...

31673 But Wat, protons and neutrons aren't really particles are they?  They are the union of three quarks each, bound together by the strong force (gluons).  So how and why do they get treated like single masses?  Is it analogous to the sun being composed of trillions of particles and yet being tre...

Modern physics shows solipsism to be true?

It is indeed a metaphysical claim.  No experiment in physics can provide insight into this question because it does not make falsifiable predictions.  I cannot prove that all of reality is not a hallucination or that you are not a brain in a vat. There are also some problems and confusions in the ar...

Okay  A-L-E-X , I need to remind you again that making many posts in a row is really not acceptable on this forum. Of the six you just posted I'll let you keep the first two.   It's also not good form to copy-paste a bunch of text from articles.  Nobody wants to read copy-pasted content.  Write your...
