I just recently went to 7th grade (I can't believe they're making us work after 3 days of school :S I thought they needed to know one another? How cruel.) and I'm now studying the universe, which freaks me out cruely. I hate mysterious things. I read an article that I had to read for school, what happened before, but there was also articles about the future that I didn't have to read. It loooked interesting, so I read it. Apparently, Galaxies collide to one another, they seperate from one another, the "Stellar Era" ends, the "Degenerate Era" will happen along with the "Black Hole Era" (Oh boy :S I hate black holes) and the Universe dies after that (The "Dark Era")

I'm just wondering, the article is really confusing :S (You know, when you read something and its so complicated and intended for smart people) so if im missing any other "-- Era" please tell me and a brief article about it? Also, can you tell me more about the Eras I stated above? Thanks :D

It all sounds complicated at the beginning, just like anything new. And learning new stuff is hard, but well worth the effort - once you understand something for the first time, boy what a rush!.

There are some really good books (yes, those hard things you have to hold and turn paper pages and all that ancient stuff) that not only are very easy to read but have some great photographs to help explain things. Go to any bookstore, check out the Astronomy section and see which ones seem interesting to you.
Astronomy magazine or their website astronomy.com or space.com are great places to look for information as well.

A quick summary of the main points:
About 14 billion years ago there was a sudden expansion from a tiny, very hot point (called the Big Bang) that started everything. As it all expanded it cooled, and around 380,000 years ago it was cool enough that hydrogen atoms could form. Everything kept expanding, and things continued to cool the hydrogen (and a bit of helium and lithium that had also formed) started to collapse into large clouds, that kept collapsing and became the first stars. They were huge, burned out fast, and exploded as supernova.
When they exploded, the pressures and heat created heavier elements (essentially nuclear fusion) that went into the next generations of stars.

Galaxies started to form (some think that the black holes that were the end result of the really big stars were the 'seeds' that attracted gas and stars around them. At first they were small, but a lot of them and they started to collide and merge, making bigger galaxies.
That's sort of where we are now.

Theories differ on the exact mechanics of how it all happened, but they're all pretty much in agreement as to what happened.

Going forward:
The universe is still expanding, so everything is getting farther away from everything else (except for the galaxies in our own Local Group, they're sort of a herd of big and small galaxies all travelling together).
Eventually, 50 billion years in the future or so, we won't be able to see any of the really far-away galaxies (they will just be too far).
Keep going into the future, and all the stars will have used up their fuel and either burned out or exploded or become black holes. Eventually, everything in our galaxy might end up inside the black hole at the galactic centre. And our galaxy and all the others may end up in one huge black hole together.
That's a LONG time in the future (maybe a trillion years).

Keep reading, keep learning - one day you'll see something that just hits you real hard and you'll get the astro-bug that a lot of us have already.
It really is amazing stuff when you get past the tough first part.

I study from the Thoth deck and so your pictures could selection. The dying card is the Zodical Trump of Scorpio and so it represents the harvest and interior the cardboard dying consists of a sickle wherein to sparkling away the previous. So once you pull that Watery Scorpio card you will see and end to previous emotional varieties and bags that we could desire to enable flow of. regrettably we are often fairly keen on the two as we've had them for a whilst :) So dying could properly be emotionally not basic till we embody it for what that's, purely yet another turn of the wheel. The Universe card is purely beatiful. it is the final touch of the cosmic cycles. So it is the 4 Cherubic beasts representing the climate coupled with Saturns form and restrict. that's putting all of the products the place they ought to be in a cosmic existence lesson form of way. returned the topic of the wheels turning is repeated. once you place those jointly that's common to be sure how as one door closes yet another door opens. it somewhat is getting your self on the the final option music interior the the final option way. that's an excellent spring after a protracted hard wintry climate. yet it is purely yet another turning of the Wheel. reliable success and revel in!

Dont let the theories of Cosmologists scare you. They are only theories.The Universe was designed as a stable system which maintains its equilbrium. It will be around for a very long long time. It is a master piece. The only thing that will happen in the future is that our Creator will improve It(make the UNiverse even better)

your exactly like me back when i was in 7th grade. don't let that stuff scare you. when they say future, they mean like billions of years from now. back when i was younger, i had no idea how far away that was. i kept thinking that I would be around then.

and black holes are creepy...your not alone

there are massive black holes in all gallaxies,dont worry you wont ever encounter one,the milkyway is going to collide with another gallaxy in a few billion years,the self appointed brains or so they think will answer your other questions...............good luck
