Do note, you have the lunar orbit going the wrong way. The only way in which it is retrograde, is in the context of its apparent motion...

While I'd take issue with your characterisation of local H0 measurements - they reach out to roughly z=1, so way farther than the scale...

As I read it, the OP doesn't want to reverse the orbit, just to identify a direction. As in e.g. a spaceship making a burn along or...

You probably want the term 'posigrade', but you'd likely need to add some qualifiers to make it clear which orbit you mean. The opposite...

The geodesic equation $$\frac{d^2x^{\mu}}{d\tau^2} + \Gamma^{\mu}_{\alpha\beta} \frac{dx^{\alpha}}{d\tau} \frac{dx^{\beta}}{d\tau} = 0$$...

The rule that "nothing can travel faster than light" is a local rule. Nothing will ever overtake a pulse of light, that is true. But...

There is a difference, not necessarily a total contradiction. Based on genetic analysis of European skeletons older than 5000 years...

I haven't had a professional view on anything physics related for decades. There is a lot of stellar modelling in that, and I don't...

Yes, the paper concludes that the age of the universe is: ##T_U \geq 13.8 \pm 1.0## (stat) ##\pm 1.4## (syst) Gyr According to the...

Frankly, I don't see where the mess is supposed to be here. The pronunciation is consistent across the main accents, with only slight...

What's important here, I think, is that they're dusty. That is, they're already evolved, having experienced enough bouts of star...

From the wiki's main list I recognise X+Y and Gifted. Both are about gifted children, with interpersonal drama as the focus and maths...

Oh, lordy. It's Avi Loeb's brainchild. I'm not touching this.

The paper provided doesn't support any of the statements in the OP. Can you provide a different source or sources as the basis for a...

Is this another one of these threads wherein everything was better when I was young and impressionable?
