Oh no don't worry I'm glad you took time to break it down, it all makes sense to me but you added a bit more to it. I can picture celestial objects closer to the core of their galaxies will move faster and mash into each other more often and influence orbits of each other and whatever was first a disc might turn more into an orb, especially in the middle, like you said with the galactic bulge.

Eh no worries, English isn't my native language, astrophysician was the closest I could get, I should have listened to the spellchecker lol. ^_^

Wait so they're sending humans to the moon again too??

There's nothing to "rule out". This is literal quackery. If you want things to rule out, you can send money directly to my paypal and I'll pay spaceX to launch increasingly exotic combinations of random materials until you're out of money (and/or I am out of homes to buy).

We won't see them as gamma ray bursts but we might see them as supernova (or hypernova) events, but only much closer.

Honestly if you've got something important to do and you feel anxious or stressed about it like exams, an important meeting etc... An existencial crisis is a good way to make you feel numb to these emotions and situations which could greatly benefit you.

For me the universe videos dont cut it aymore so i just usually go watch an animal eaten alive or just something to make me generalize life and existence and to remind my brain that the problems i have right now dont matter because you and everyone around you will be dead and life is neutral in the end

Maybe it's just the start. They launch a station, that then supports a close orbit like how it is on earth. It'd be cheaper to maintain for Lunar built satellites, cheaper and less risky to launch, and easier to send replacements or expansions.

>aren't most galaxies disc shaped?

Uhmm... "yes and no". Most galaxies are disk shaped, but most stars in the universe are in elliptical galaxies, which are "blob-shaped". Elliptical galaxies are really huge, so a relatively small number of them really dominate. For example, the relatively nearby M87 is 200x the mass of the Milky Way.

​

>Not very hard to imagine that since gravity is the force that rules over galaxies, solar systems and planets, then the distribution of stars around the massive object in the galaxy, the distribution of planets around a star, and the rings around a planet, is all from the same force,

Uhmm... "yes and no". Gravity is king, but there is also gas pressure.

This happens to be my area of research, so I hope you won't mind if I take a tangent:

In a pure N-body system with no gas, the long-term evolution is that close encounters between massive particles (e.g. planets, stars) cause random perturbations to the orbits, so over the the system approaches the shape of a blob. You can see this in globular clusters inside the Milky Way, and you see it in elliptical galaxies.

The reason disk galaxies and planetary systems don't look like that is that they were originally made from a gas cloud. In a gas cloud, gas particles collide with each other, and that tends to remove the random motions. So you are left with only the average motion, corresponding to the "net" angular momentum of the system. And that's how you get those clean, flat disks. The disk around a black hole is the same.

Gravity Only = Blob

Gravity + Gas = Disk

Today the solar system has almost no gas, and the Milky Way has already used up 99% of its gas. But because the planets and the stars were born in the gas, their present orbits reflect the shape of that gas. But if you look within the Milky Way, you will see that the oldest stars have more random orbits, making a thicker disk than the one made by the youngest stars. These are in fact called the thick disk and the thin disk.

Oh, and I just thought of another example. The galactic bulge of the Milky Way has a very large star density and it is very old, and that's why it looks like a blob. It's like a mini elliptical galaxy.

​

>Maybe if the massive thing at the middle wasn't rotating it wouldn't spread out into a disc, i'm no astrophysician.

I mean this in the kindest possible way: The term is "astrophysicist".

A physician is a type of doctor (what can I say? English makes no sense).

A physicist is a scientist that studies physics.

my balls are glowing green!

Seriously? Has the US forgotten that it was the first to implement the WOLF Act?

sometimes but i am a human and do stupid human things so i cant think of important stuff like the universe

Depends on if you consider a stable orbit “roaming”!

The moonbase’s red alert klaxons will be the Nokia ringtone.

secret base on the moon is sick of slow ass internet! hook those dudes up!

Sub orbital space marine insertion here we go

Ah, but Sagan would make you feel quite at ease. He'd even laugh at your "billions and billions" joke.

Well, it's not like there's much people to cause network congestion there.

Hey! I liked my Lumia 1320...

I would prefer a picture of Carl Sagan. You cannot disappoint a picture.

Dinner with him would be him talking and me fumbling with silverware, dropping food, and meekly mumbling Cosmos quotes.

You put down the thought in my head very eloquently. I read a cosmology book 12 years ago and I have become an atheist. As Jimmy Care says , it’s a lonely experience, it’s a revolution for one. I fell into nihilism and I still haven’t found any purpose in life. We will all disappear. I went through my late grandfathers photos, who was born in 1891. He lived, he suffered and in 100 years nobody will remember him. Our existence is pointless, we are a product of a coincidence. If anyone can cheer me up, you’re welcome:)
