I don’t think humans’ brains are big enough to imagine the size of the universe

This is very true. It’s hard enough to comprehend one light year, let alone 13 Billion of them.

President Joe Biden 2022 and advanced Astro-Physics -a bit of a mismatch

Same goes for almost all of us.

I don't know how many moons you have over there in the good old US of A, but over here we only have one :)

Are you sure?

Are you sure?

Every day is a school day :)

Are you sure?

What about Gemma Collins?

Anyone explain this? Super moon last night because it was closer to Earth in its orbit of Earth. Why? The moons orbit is influenced by the Earth's gravity, presumably a dropped object accelerates at the same speed if its dropped in the USA or Asia. Which means that the Earth's gravitational pull is the same around the globe. So why isn't the moons orbit a circle instead of being elliptical?

Does that mean we have been singing the wrong song for 30 years and it should 'Blue Planet you saw me standing alone?' and that doesn't work as we could be singing about planet Earth as well - Shit! now we've got no science as well as no history :-(

“Space is big. You just won't believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it's a long way down the road to the chemist's, but that's just peanuts to space.”​

― Douglas Adams, The Hitchhiker's Guide to the Galaxy

Just about sums it up.

Haha! It does, best tell the boss to change the site think I’m disappointed the moon is a planet a fact I must have forgotten

Without looking it up, isn't it because of the suns gravity influencing the orbit and making it elliptical?
