Title: New Galaxy
Post by: earl1937 on May 06, 2015, 10:07:13 AM
:airplane: Just saw a story about a new galaxy, now get this, I have to put it on another line to get all the numbers in:
78,000,000,000,000,000,000,000 miles away!! Holy cow "Batman", how do you pronounce that?
If we had a space ship of some kind, which would travel at 1,000,000 miles per hour, how long would it take for us to get there? I would think 2 generations of humans, but I am not that good at math! Wow, who in world would want to spend their whole life on a space ship? After seeing how many signed up for the "Virgin" space folly, I would guess there would be a lot of takers.

With the leaps and bounds we are taking (less since the world wars), we will no doubt find a way to span great distances otherwise thought impossible.
I always hoped that the inter-stellar space was a mm thin, like all matter passing through this interstellar space was stretched to appear as if the next start was "light years" away but was in fact, right beside our own stellar "bubble" if you will..
Like if our voyager probe just all of a sudden appeared to be in the next star system, breaking the "bubble" and appearing in the next stellar sphere of influence.
All very exciting stuff!

The only known way we could ever traverse that distance in time before the end of the universe is by wormhole or an Alcubierre drive. The last one we might be able to make work (perhaps even in my life time, but probably not in yours Earl :()

It would take way more than 2 generations of humans. The nearest star, which is 4 light years away would take 19,000 years to reach with our fastest craft which travels 155,000 mph.
This galaxy is like tens of thousands of light years away. It would take us millions of light years to get remotely close.
By the way what was the name of this galaxy.

OK a few issues here: at the snail speed of 1 million miles per hour, it would take you about half a billion years just to get out of our own galaxy... That is more than the entire history of planet earth since the first dinosaurs - a bit more than 2 human generations... that speed is not even enough to overcome the expansion of the universe, so you may never reach your destination (we see it moving away from us very very close to the speed of light).
If you increase the speed to very very close to the speed of light, the passage of time for the people inside will slow down relative to you, so the travel for them will seem shorter. This is somewhat similar to putting them to sleep for the journey.
That galaxy is both "new" and very very old. The light took about 13 billion years to get to us, so you are observing a galaxy which is now 13 billion years old, but you see it as a very young galaxy. In fact, it is older than our own galaxy.
You must have a real hard time if even a blow up doll says no.
Exactly.

We can look at a galaxy as it was in the past but when we get there it would be the present. We are looking at something that is not even in the same place today.
Guys remember when taking about lightyears it's discussing the distance traveled for one year at the speed of light..
Speed of light is about670,616,629 mph ( 186,282 miles PER SECOND)
1 lightyear is around 5,880,000,000,000 miles.(trillion) So if something is 13 billion light years away...that means
13,000,000,000 Times 5,880,000,000,000
74,440,000,000,000,000,000,000 miles :)
Soooooo, 3 cases of beer?

Read something about how NASA may have accidentally discovered warp drive while testing a new type of thruster on one of their space crafts. The craft barely moved, but the particles that the thruster was ejecting were clocking in at speeds faster than what light is known to travel. They are looking into the issue to see if faulty equipment may have caused an error or if this is legit.
13 billion light years away is nearly as old as the universe itself. The estimated age of the universe is 13.7 to 13.8 billion years old. That makes this galaxy the oldest known galaxy in the observable universe.

Well remember the universe is expanding and as time goes on more and more will become visible to us.
And remember light years is a unit of measuring distance...not time, the observable universe is about 92 billion light years across.
It takes the light 13 billion years to get to us, but remember it had been traveling in every other direction(including away from us) for 13 billion years too :)

Agreed. If I remember correctly, two out of every three stars has at least one planet orbiting that we can detect from earth. Once you start crunching the numbers, any gambling man would tell you to put your money on the fact that we are not alone.
Will we ever meet them? I doubt it, we're still so young in terms of space exploration that it's not likely that we'll ever make contact in our lifetime. Though I would love to be proven wrong on this.

Another thing to consider is that we may be the only intelligent life form right now. Space is vast, but so is the time frame. Civilizations may have come and gone many times before us. Human civilization has so far existed such a short time that in astrophysics terms it is hardly measurable. Not even a blink.

Of course the time frame is vast, civilizations come and go in the blink of an eye, but still, mathematically speaking, we are no where remotely close to being the only intelligent life form with a civilization.

Look up the Drake equation, it puts together all factors such as rate of star formation, fraction of planets with stars, and so on, and according to the equation it is estimated there are about 140,000 in our own galaxy.
Now of course it's just an equation. Any civilization "included" in the equation might not exist anymore, to answer that very question

It's very possible, of course now I can't go into depth with this stuff, I only love reading about it. I don't want to be called a cut and paste cosmologist or something like that.
But after all I've read and watched, despite life-supporting planets like ours having small chances of existing, that small chance in terms of the Galaxy (with hundreds of billions of stars) where that "1 in 10,000" ratio is played over and over and over...must mean we have a hell of a lot of neighbors.

One in ten thousand being life bearing planets? If so then the chance of any of them having intelligent life at the same time is not = 1. We've been around for about 200,000 years and we could be gone tomorrow.

It isnt really 1/10,000 I was just using it as an example.
I'll look it up
Have found some info, try this out, this says 1 in every 6 stars has a planet that is Earth-sized (not necessarily habitable for life) and is within 85 day orbit of its star.

Post by: Dragon Tamer on May 08, 2015, 06:31:19 PM
There are two stars, one is 2 light years away, the other is 4 light years away. Both have planets orbiting their star within the habitable zone, though one is on the hot side, the other is on the cold side. They think that the cold one may have some form of life on it, though it may not be noticeable yet (because of how long it takes for life to evolve to a point where it can start to change the topography(?) of the planet. The hot one is tidally locked to it's star so the side towards the star is baking, the other side may have some kind of life though it was said that it's unlikely.

Why do these intelligent life forms have to be humanoid?
They would most likely be bipedal, giving them the ability to move objects with their hands like we do. This is a critical part of a society evolving. The other details on the other hand are up in the air, and would most likely change depending on the environment of the planet.

Tho I may not be alive to see it in the next 25 to 100 years I think were going to find out life is so abundant in the galaxy people will look back at 2015 and see people who thought the earth was flat. We are getting so good at finding planets and spectrometry. In just one year while analyzing just one tiny patch of sky the Kepler observatory has found over 700 planets orbiting stars. Now its believed EVERY star has at least one planet. Most have far more along with many moons.
In the next few years observatories will be launched that make Kepler and Hubble look like toys. They will be able to analyze the light reflecting off these planets and tell us what they are composed of. In other words if a rocky planet is in the "Goldilocks" zone of a stable star and we are able to analyze the light reflecting from liquid water, oxygen, Chlorophyll , carbon dioxide...ect we can pretty much surmise the planet holds life.
And there are 100 m to 200 m Galaxies in the known universe and at least 100 m stars in each galaxy. My belief is the universe is teeming with life beyond count and even in the Milky Way there is intelligent life numbering in the millions.
The arrogance eh? What makes us so special?

What really bothers me is what if we are the most intelligent beings? We always imagine aliens as an ancient race with god-like technology. What if WE are the elder race and everyone else are even more stupid than us...
Imagine a galaxy full of slobbering monkeys who throw their feces at each other... and then us pathetic humans arrive and demand "take us to your leader!"... and that is all the universe has to offer.
