That's very interesting An'shur . I'm very skeptical with FTL travel been possible at all but expansion rates are an interesting topic in relation to all the speculative field of the Fermi paradox. I'm also very skeptical of extraterrestrial intelligence at all. I like the fact you thought about...

I was going to say the same. Gnargenox, are you researching in the field?

tRetro-Visor, those are true masterpieces.

I even understood 10% of it, it was so well explained! Hahahahahaha :lol: I'm learning a lot right now while I make this so plase add me to the prehistoric group of people here. Ok so let me say that I have changed a lot of the previous post because I think I was falling into another missconception...

21371  I did try directly computing orbits with and without perturbation just to try to get some intuition for how the perturbation effect works.  For starters I assumed co-planar, circular orbits, and also that only Neptune perturbs Uranus and not vice versa (which probably matters very little). W...

22388 They would say that the astronomers methods are 'unfalsifiable'  from their viewpoint, simply because they do not understand them (having never studied physics, chemistry or astronomy in general). I have to agree with Watsisname here. I think the fact that something is important or not is not...

A paper has been published that examines the Earth as an exoplanet from the context of transit detection methods from other stellar systems. So this is a little off-topic but I prefer to write this here since a new thread would be unnecessary in this case. The paper is called " Transit Visibil...

21605 Lagrange Points and Trojan Orbits Gravitational balance and stable configurations in rotating reference frames I've sort of returned form holidays now. Watsisname this is so so interesting and well explained I have no words for it. There are a lot of canonical explanations but all I've seen s...

Qr Bbpost Apparently I never posted my ISS solar transit photo here. Time to fix that.

Wooow HarbingerDawn that's an award winning level shot. Amazing, right in the center and without any motion blur. Just perfect.

22206 For god's sake, please code into the game the ability to create your own stars, planets and moons into the game. In short, to create your own stars systems from scratch. It could have been easily done from the beginning. 1.- There are no orders, exigency and demands theads in the forum. Just ...

22197 Whether or not we send targeted radio broadcasts to specific destinations does not matter. We have been telling the universe for over 100 years now that we are here! I'm curious as to how the radio power output of Earth has changed in those 100 years. Maybe that can tell us about how far thos...

21964 I calculated that I've spent just over a week airborne over the past 12 months covering a distance of about half a light second.  Does this also mean that I've travelled half a second further into the future than if I'd remained at home, or is the maths more complicated? Half a light second (...

Mathlogger did an excelent video recently about this and how is connected to Fourier series. qS4H6PEcCCA At the end of Geocentrism astronomers started to add epicycles on epicycles. This nested structure worked (and works still for the complex orbital perturbations we are able to measure today since...

21812 Working Wormholes I know that you are already planning to add this, but It's just a reminder. Has been proposed several times and there is an entire thread for this where it has been discussed. 21812 A Multiverse When you are flying out of the Universe, for example with a spaceship or just in...

It looks like people is starting to refine 3D models for asteroid Ryugu (now been visited by Hayabusa2). This model was made by Roman Tkachenko. I've been unable to locate the actual model but I guess we will have the opportunity to see it in SE when a model based on better data arrives. 7-7xg4XAcIk
