My old science teacher told me many , many years ago , that if you truly want to know the size of the earth , or how it compares to all the other planet's and stars out there , and how many we " think " are out there.......just simply walk onto a large ocean beach , pick up one grain of sand , and you'll be pretty close. Because adding all those planet's and star's together is about passing an actual number.....it's about infinity. One thing in this video is the little yellow square that they show about 1/2 through.......and that little square is how far we have actually been able to see out with the tools we have available. Basically , like looking out your front window across the street.
This stuff has always amazed me. Makes you wonder , and something I have always thought about. Our civilization ( as far as we can tell ) goes back about 30,000 years. What " if " , in older galaxies ( or maybe even our own? ) intelligent life started 1,000 , 10,000 , a million , 100 million years or more before we did? And if they are alive.......what kind of science have they developed? And if they are out there.......is the vastness of space so large that none of us will ever be able to communicate? Has it already happened with other planets that harbor life? I wish I could be around in 10,000 years to see what we find.
100 billion. Keep in mind that 1 million seconds is about 11 days. 1 billion seconds though is about 31,5 years. Billion is a big number and it's commonly represented in the known universe.
I'm here to tell you, since space is endless, so is the number of galaxies.

Blew my mind at the time lol
And then you still haven't gotten anywhere far in the grand scale of things.
Look at wash gravel. Comes in different colors. A grey stone. A white stone and a tan stone. Those 3 clusters appear together at different points on a wash gravel bed. Now the more complex the pattern the father you have to look on that gravel bed. But it’s probably there. Say a 9 rock cluster with the same color all touching one another. You’ll have to walk all over that gravel bed but I bet eventually you’ll find another 9 Rock cluster.
Now take what mr x just said and that 9 rock cluster become a 9 million rock cluster. Rare but probably out there....just gotta find it .

I bought a 4 inch Meade refractor back in ninety,just enuff to pis S you off.
So, I got a twenty inch reflector,it's on a Newtonian type mount but that made it cheap .
When looking at andromea it is just awsome,I highly recommend a scope,even in the city you can see planets.
Right now at sunset venus is fartherest west then Jupiter a little easy and Saturn in the east.
Look up at sunset,first ",stars" out are those three planets.
You can see jupiters tour moons with decicent binoculars

I believe it's a lot harder for us to actually see through our own galaxy , because of all the other object's and gas that are in the way. But looking out of our galaxy , we see to be able to get a clearer picture.
What's your guy's opinion's on possible other intelligent life on other planet's , that could of formed thousaund's , if not million's of years ahead of us? I mean , seriously think about it......if our universe is around 13.7 billion years old , and us ( human's ) are only about 30,000 year's old , which is absolutely no time at all. It's like a blink of an eye in a time period of 13.7 billion years. Look at the advancement's in technology Human's have made in just the last 100 years , compared to the 30,000 years we have been on this planet. It's literally crazy to think about how we have exponentially advanced in that amount of time.
I also remember reading an article saying that they thought our galaxy ( the Milky way ) was basically in mid-life. Plenty of newer , younger galaxies , but many which were a lot more matured and older. Even having intelligent life form 10 million years before us......is still hardly any time at all.
What's interesting is our solar system travels at an average speed of 515,000 mph and at that speed it would take about 230 million years to travel all the way around the Milky Way.
The numbers are just mind boggling.
That's just within our own milky way.
There are hundreds of billions, perhaps hundreds of trillions of galaxies out there.
Awesome wonder.
The universe in this dimension is not infinite, if everything the scientists believe is true.
It began with a single point of no size and infinite mass that was situated nowhere and "no-when," then an awesome expansion of energy blossomed out in all directions. The expansion, called the Big Bang, expanded at speeds greater than the speed of light (even though that is impossible,) then slowed to its current rate of expansion, which is perhaps a significant portion of the speed of light. (This all sounds a heck of a lot like, "Let There Be Light" to me, but let's leave that discussion for another time.)
So, the physical universe, which I prefer to call "the limits of the 3rd dimension," has been expanding for roughly 13 billion years at speeds above and/or approaching the speed of light.... into what? There is an "edge" to the universe, but it doesn't exist in our dimension. Let that one warp your noodle for a minute.
