    Smallest, Faintest Galaxies of the Ancient Universe Spotted

    Just 3.8 billion years "further" viewing, and we could see them all. :leet:

    And they used the light from closer galaxies as magnifying glass. This is cute:

    For no real reason been reading up a lot on the age of the universe and associated things for ages. There is now arguement that that universe could be a lot older than originally thought and that we will never be able to see the full extent or even close to it using our current technology.

    Now all we have to do is create a way of getting there :Paranoid:

    An infinite playroom. Was reading last night about the expect number of planets in the universe, taking away the infinite concept, and was in the trillions for our galaxy alone.

    Our Milky Way has trillions of planets? That's difficult to imagine. I think current estimation are more in the range of a few hundred billion + a similar number of stars. Interesting that we even know nothing much about our own galaxy.

    Did some reading in the all knowing Wiki and found this, apparently referring to the same finding reported in OP

    http://en.wikipedia.org/wiki/Galaxy

    They put the visible age "just 700 million years" after the big bang, which is nothing in the grand scheme of things.

    That's still one of the great unanswered questions.
    Is the universe teaming with sentient beings or are we alone?

    There's good arguments either way and I find it hard to know which answer I'd prefer.

    If the universe is as large as thought then there mathematically has to be other life.

    It does not read very scientifically. ;) But I don't mind whether our Milky Way has a few hundred billion planets as usually thought, or two-to-three trillion planets as he believes.

    Probably in our galaxy alone there are many planets with earth like conditions that would support human life, and then there are for sure many planets existing that provide the environment for other lifeforms.

    With our current technology I don't beleive we will detect other life.

    But I do believe it exists. With so many other planets, I cant see how there couldnt be.

    I might be the only one but I'm actually quite excited by the possibility of other life out there. Certainly not terrified. But it's a nice quote.

    It's certainly an entertaining thought but levels of technology, mainly ours, will make detection damn slow I think. At least with what we have now.

    I also believe it exists. There must be millions of planets with earth like conditions. But it's mute, there seems to be nothing within our solar system, this means there will be never any actual "contact".

    For sure plenty of earth like planets. Add to that the ones that have conditions where life such as the extremophiles could exist and the possibilities seem great. What we don't know is if those unusual forms of life could ever evolve into anything intelligent. All the life forms here that have advanced much beyond slime are carbon based and oxygen breathing.

    Up against that we should remember how close life came to being extinguished on this planet from things crashing into it. Evolution here suffered a few major setbacks.

    For sure true contact (two way communication) is beyond us unless they happen to be very close by however we are putting a lot of effort into listening and so far nothing.

    'Transcendence'. Any critter smart enough to build a transmitter, will be smart enough to eventually figure out how the universe is structured at its lowest level, and enable it to escape the universe. The time period between discovery of radio waves and transcendence capabilities are probably very short compared to geological and evolutionary time scales.

    I found this thread to be quite informative until I got to this post....

    Intellect limited?*

    What RnR is describing is technological advancement, not necessarily Moore's law, but a doubling of human knowledge approximately every 10 years. In some fields, its even less. I suggest you look past the language barrier to find the concept. If you need help, here is a link.

    Additionally, forgive me for being pedantic but magnification is a by product of lensing. No actual magnification occurs, rather a concentration of light, along gravitational planes, occurs.
