just becaue it not a country song does not mean it is not music..Music is sound dah!!!!!!!!

[BengalbobZilla]

Now that she's gone, we can have a logical discussion about this

Saying all sound is music still is WRONG!

As we get better technology to view more distant regions of space and get better close ups on our galaxy and our nearest neighbors we will unlock more of the universes secrets.

And the universe is still in a constant state of expanding so those distant universe are only getting more distant.


First Goal as a species is to get to mars lol Then we can work on getting out of our solar system.

Nifty stuff.


Universe is so vast, we will never see the vast majority of it. Like living on the beach and only seeing a single speck of sand. So much more stuff out there, have to wonder at what all is out there we haven't even thought of.


Heck, we even have photosynthetic animals here on Earth, so the possibilities are endless. Not I believe there is a Lexx ship out there, but almost anything is possible I guess...

The European Space Agency’s Herschel space telescope has discovered that previously unseen distant galaxies are responsible for a cosmic fog of infrared radiation. The galaxies are some of the faintest and furthest objects seen by Herschel, and open a new window on the birth of stars in the early Universe. Astronomers estimate that there are billions and billions of galaxies in the observable universe (as well as some seven trillion dwarf galaxies). ESA astronomers say that for every ten far galaxies observed, a hundred go undetected.
Here's how astronomers breakout the visible Universe within 14 billion light years:

Superclusters in the visible universe = 10 million

Galaxy groups in the visible universe = 25 billion

Large galaxies in the visible universe = 350 billion

Dwarf galaxies in the visible universe = 7 trillion

Stars in the visible universe = 30 billion trillion (3x10²²)

Astronomers realize that they may have underestimated the number of galaxies in some parts of the universe by as much as 90 percent, according to Matthew Hayes of the University of Geneva's Observatory, who led the investigation using the world's most advanced optical instrument -- Europe's Very Large Telescope (VLT) in Chile, which has four 8.2-meter (26.65-feet) behemoths. They turned two of the giants towards a well-studied area of deep space called the GOODS-South field.

In the case of very distant, old galaxies, the telltale light may not reach Earth as it is blocked by interstellar clouds of dust and gas -- and, as a result, these galaxies are missed by the map-makers.
"Astronomers always knew they were missing some fraction of the galaxies... but for the first time we now have a measurement. The number of missed galaxies is substantial," said Matthew Hayes of the University of Geneva's observatory, who led the investigation.

The team carried out two sets of observations in the same region, hunting for light emitted by galaxies born 10 billion years ago.The first looked for so-called Lyman-alpha light, the classic telltale used to compile cosmic maps, named after its U.S. discoverer, Theodore Lyman. Lyman-alpha is energy released by excited hydrogen atoms. The second observation used a special camera called HAWK-1 to look for a signature emitted at a different wavelength, also by glowing hydrogen, which is known as the hydrogen-alpha (or H-alpha) line.

The second sweep yielded a whole bagful of light sources that had not been spotted using the Lyman-alpha technique. They include some of the faintest galaxies ever found, forged at a time when the universe was just an infant.

The astronomers conclude that Lyman-alpha surveys may only spot just a tiny number of the total light emitted from far galaxies. Astonishingly, as many as 90 percent of such distant galaxies may go unseen in these exercises.

"If there are 10 galaxies seen, there could be a hundred there," said Hayes. The discovery adds powerfully to knowledge about the timeline by which stars and then galaxies formed.

The image at the top of the page shows the discovery of a previously unresolved population of galaxies in the GOODS fields and the first measurements of properties of galaxies in the almost unexplored far-infrared domain are among the first exciting scientific results achieved by Herschel's PACS and SPIRE instruments. These findings confirm the extraordinary capabilities of ESA's new infrared space observatory to investigate the formation and evolution of galaxies.

I wish I could herp this post, but I must spread it around first.

Awesome thread. Sorry it got polluted.

Thinking of just how big the universe is is truly mind-boggling. Seriously, If you traveled at the speed of light in any direction, it would still take millions of human lifetimes to reach the outer reaches of the known universe.

The light that you see from stars happened soooooo long ago. Like it was said earlier, I wish I could be around to see some of these mysteries unfold, but I strongly doubt it.

Here's my stance on such things...

Computing power doubles roughly every 18 months. Some say that rate is slowing down now, but for the sake of argument, let's assume that same trend continues. That means that in roughly 50 years, we'll create AI, or something similar to it...something that has as much computing power as that of the human brain. Most of the time, people thinking of this process stop there. YAY!! AI!!! However, keep going another 18 months and you've got something twice as intelligent as a human...36 months later, you're 4x as intelligent...you can see where I'm going.

As long as nothing bat-poop crazy happens in the next 100 years, this next century is going to be a period of amazing technological leaps and discoveries. Of course the super smart computers turning on us might throw a wrench into all of that. But assuming we can work together with them, or integrate them into ourselves, humanity could be racing off to the stars in a few hundred years. That's my take on it anyway.

I hope my son is around to see some of it. I hope my grandchildren say "wow! If only granddaddy could have been around to see this!!!"

I just happened to find this in a manner totally unrelated to the article posted at the beginning of this thread. This video shows galaxies surrounding the Milky Way and their relative position to one another. There are only 400,000 galaxies in this video, but hundreds of billions in the observable universe!!!

What more powerful creation than the Big Bang and billions of billions of galaxies ?

And life is everywhere not just on that planet.

Stop being self centered.

Im guessing the first Aliens we run into... Arent like what you see in star trek lol..

More likely a Star Ship trooper or "Aliens" Senerio... Hive mind space insects.

There was a game i used to play called FreeLancer on Pc... you basically get to fly around and explore a galaxy it was pretty cool (trading and quest available too)

last time i played it there was a FireFly ship

Wasnt there talk of a Near by galaxy possibly crashing into ours?

I think its the Andromeda galaxy, that will eventually crash into the Milky Way in about 4 billion years

Oh if thats the case our sun will be a red giant by then and Earth a Roasted shell.. so We need to think about moving.
