I watched my first SpaceX launch yesterday. Just so much thrust to get into Earth orbit, and around 17,000km/h. They loaded a million lbs. of LOX into the first stage at launch OK, so they needed a few lbs. to land, but STILL.

All those zeros and it gets confusing. I wouldn't be surprised if my response is incorrect in some way or another.

It doesn't matter. What's it worth being allowed to drive a zillion km/h on the German Autobahn: got no tools at our disposal for that and couldn't physically 'stomach' it anyway. But an interesting hypothetical for science.

We are all just a near infinite tiny blip in space and time. But at least we can claim a lifetime of existence on the face of a planet in The Big Void. Cogito, ergo sum (and for mankind existence reasons also coito, ergo sum applies).

Moons that are freakishly all exactly the same size.

UY Scuti BD-12°5055,
the biggest star in the universe (that we know of), UY Scuti is a variable hypergiant with a radius around 1,700 times larger than the radius of the sun.

To put that in perspective, the volume of almost 5 billion suns could fit inside a sphere the size of UY Scuti.

It's going to make a great black hole some day.

Wikipedia link says 909 radii, 750mil volume...

Well from my days as a professor, Wikipedia is not considered a reliable source…

Space.com says the same as LJ.

I’m sure we’ll get to the bottom of it eventually!

The four largest asteroids. If one was to hit earth, you would need a lot of Preparation H®.

If Andromeda was brighter, this is how big it would appear in the Night Sky. Reminder this Is heading towards us at a speed of 300km a second. But since it is located 2.5 million light-years away, it might take a while.

Olympus Mons on Mars is the tallest mountain in the known Universe at 72000 feet. Everest is only 29032 feet.

Im surprised we didn’t make a bigger deal of water on mars. We were all hyped about that shit in 1983.

72000ft above sea level, I hope?

The Carina Nebula located 8500 light years from earth.

https://en.wikipedia.org/wiki/Carina_Nebula

Nebulas are a distinct luminescent part of interstellar medium, which can consist of ionized, neutral, or molecular hydrogen and also cosmic dust. Nebulae are often star-forming regions, and impressive to look at. Some are several light years across.

[Llarry]

The Pelican Nebula is about 1,800 light-years distant from Earth and about 30 light-years across.

Or ARP 273. 300 million light years away.

Absolutely. It's identical to all religions; it mixes truth and lies so seamlessly that the reader believes the entirety to be truth, when in fact it's not even nearly that. It's how they are both sold.
