So every star we see in the sky is a different solar system

[Larry the boss]

Guess I am old because we were not taught that in school...So how many solar systems are in our own galaxy?? or do we even know anymore??

[Beercules]

Not sure the exact number but space is a ****ing trip.

Some of those stars you see don't even exist anymore they are so far that the light is still traveling to us.



Smoke a blunt and watch this documentary when you're bored dude.

The scale of things is impossible to fully grasp

Are you asking if every star we see has planets?
Well there are things to know first. IIRC half the stars we see are not single stars, but have 2, or 3, possibly more stars orbiting around each other. The extra star[s] affect the ability to have stable planets. But yes most stars should have planets.

There are about 100 billion stars in our galaxy, the Milky Way. And there are about 100 billion galaxies in the universe.

You might like The Elegant Universe with Brian Greene for modern cosmology and physics for laypeople.

Just watch.

Just watch.

Also, in the middle of every galaxy are masses of ultramassive black holes that are so dense, so big, and is under pressure so incomprehensibly great that they bend time and reality. The forces are so massive and wild, that reality and time collapses into itself.

The state of reality in the core of a galaxy is entirely unknown and inexplainable.

Imagine that in the middle of the galaxy is a vacuum of gravity so intense that it holds hundreds of billions of stars together.

If you go to the core of the galaxy, an area of space the size of a ping pong ball would weigh more than septillions of tons. And imagine if you could look microscopically into the core of the galaxy. The gravity, the pressure, the state of reality would be absolutely unimaginable.

If there was someone 65 million light years away right now, looking at earth through a telescope, they would be looking at dinosaurs.

When you peer into space, you're not looking through distance, you're looking through time.

Astronomy was my favorite subject in college, hands down. I was such a nerd in that class.

Yeah it is another star system in our galaxy, but not another Solar system. The Solar system is the name of our neighborhood. It comes from the name of the Sun in Latin, Sol. There's only one Solar System, because there's only one Sun. Sun is the name of our star.

All the other stars you see, they have a different name, that name is what ever the 'aliens' in that neighborhood of planets named it, if there is any. Lol.

But in short, yes, it is another star system like our Solar system. Especially the red, orange or yellow one's. Those colors indicate they are cooler, longer lived stars that could burn for billions of years and who may have a planet in its orbit that is in its habitable zone for a long time, long enough to develop life.

Unlike the bluish, bigger stars which are known as hotter stars that burn through its energy in millions of years and are unlikely to have habitable planets in its orbit because they don't last long, they die fast (relatively fast in universe time), they're too hot and they're so big that when they blow up they will destroy any planet around it.

I get what you mean, but looking at dinosaurs would be impossible. They'd see Earth. But to see such detail of Earth, like dinosaurs, they would need an impossibly big telescope. A telescope that defies the laws of physics.

Shut up, Kev.

No one likes you, and yo momma dresses you funny.

You ol' dude from No Country for Old Men haircut having ass.

Ol' Megatron boxhead lookin' ass.

Ol' Clint Eastwood's jawline from Magnum Force lookin' ass.
