Most Earth-like worlds have yet to be born

    Earth came early to the party in the evolving universe. According to a new theoretical study, when our solar system was born 4.6 billion years ago only eight percent of the potentially habitable planets that will ever form in the universe existed. And, the party won't be over when the sun burns out in another 6 billion years. The bulk of those planets -- 92 percent -- have yet to be born.


    This conclusion is based on an assessment of data collected by NASA's Hubble Space Telescope and the prolific planet-hunting Kepler space observatory.


    "Our main motivation was understanding the Earth's place in the context of the rest of the universe," said study author Peter Behroozi of the Space Telescope Science Institute (STScI) in Baltimore, Maryland, "Compared to all the planets that will ever form in the universe, the Earth is actually quite early."

    Looking far away and far back in time, Hubble has given astronomers a "family album" of galaxy observations that chronicle the universe's star formation history as galaxies grew. The data show that the universe was making stars at a fast rate 10 billion years ago, but the fraction of the universe's hydrogen and helium gas that was involved was very low. Today, star birth is happening at a much slower rate than long ago, but there is so much leftover gas available that the universe will keep cooking up stars and planets for a very long time to come.

    "There is enough remaining material [after the big bang] to produce even more planets in the future, in the Milky Way and beyond," added co-investigator Molly Peeples of STScI.

    Kepler's planet survey indicates that Earth-sized planets in a star's habitable zone, the perfect distance that could allow water to pool on the surface, are ubiquitous in our galaxy. Based on the survey, scientists predict that there should be 1 billion Earth-sized worlds in the Milky Way galaxy at present, a good portion of them presumed to be rocky. That estimate skyrockets when you include the other 100 billion galaxies in the observable universe.

    This leaves plenty of opportunity for untold more Earth-sized planets in the habitable zone to arise in the future. The last star isn't expected to burn out until 100 trillion years from now. That's plenty of time for literally anything to happen on the planet landscape.

    The researchers say that future Earths are more likely to appear inside giant galaxy clusters and also in dwarf galaxies, which have yet to use up all their gas for building stars and accompanying planetary systems. By contrast, our Milky Way galaxy has used up much more of the gas available for future star formation.

    A big advantage to our civilization arising early in the evolution of the universe is our being able to use powerful telescopes like Hubble to trace our lineage from the big bang through the early evolution of galaxies. The observational evidence for the big bang and cosmic evolution, encoded in light and other electromagnetic radiation, will be all but erased away 1 trillion years from now due to the runaway expansion of space. Any far-future civilizations that might arise will be largely clueless as to how or if the universe began and evolved.

  2. I caught this article when it first came out, it made me think of us as the Ancient Race of the galaxy. Thousands, possibly millions, of years in the future younger races will be studying our old junk. Seeking the answers to the Universe, following a galactic trail of bread crumbs, solving the puzzle that was Humanity. And if we are one of the first on the scene, think of the huge empire we could build by conquering less advanced civilizations. Many will argue that we should not involve ourselves in the development of other life forms. We all know that is never going to happen... The beautiful thing about capitalism is that it drives innovation and the bad thing is that it ensures we are going to exploit anything that is exploitable. Then we will rewrite history a bit and make ourselves look better, claim it was all necessary. So we will build a galactic empire, the question is who will rule it? And what forms will THC take on other life sustaining worlds.

  3. Their cosmological model is such a disaster I have strong reservations for any claims they make under using such a model.
     
  4. I've often wondered if maybe our race is one of the early ones. One of the first. Who knows, I very strongly believe there's extraterrestrial intelligent life, but I also wonder if we are one of the first few.. The whole travel the stars via hyper-drive may be a huge reality, just not for a race as early as our own..

  5. Based on David Wilcock's work there is an estimated 100 million earth-like planets with intelligent life.
    I understand and believe our planet is quite rare but nothing that falls into a category of "Special".
    Religions only make it seem that way so individuals don't go wondering off and thinking outside the box. Aliens or Extraterrestrials were replaced with demons and similar things like that leave these people in a more fear-based mindset keeping them limited to believing anything more intelligent them themselves does not exist especially outside this planet. IMO

  6. Very cool. I was thinking something like this recently

  7. Or made. Terraforming will likely be in our future if we last long enough.
     
  8. We won't last long enough for Terra forming. We will definitely kill each other with nuclear weapons before that. That is if we have even traveled to space in the first place......

  9. I don't know. The expected retaliatory response is a strong deterrent. A country would have to have some really fucking insane people in power to actually go through with a preemptive nuclear strike knowing the consequences.

    In theaters everywhere on doomsday.

  11. I personally doubt we'll ever have a nuclear world war but who knows? Put the wrong people in power and you dont know what you'll get, we thought we were civilized but just less than 80 years ago we were blowing each other to pieces in ww2

    Yeah i doubt it too for a more extreme reason. People who are in contact with aliens and extra terrestrials have also said there will never be another nuclear war because of the damages it causes to the solar system. The Energy goes beyond our earth and interferes with other lifeforms that exist within range. Apparently US and some others have launched many of them last few years but all have been strangely disabled in mid air by some unknown advanced technology. They say Light ships surround our earth now to prevent more of this stupidity from occurring.

    These ships have complete stealth technology beyond anything we understand yet possibly from highly advanced species that we are unable to detect or stop. Some say they can replicate in forms of clouds others say they simply exist within a higher dimension/frequency thus we are unable to detect or even comprehend how it could be possible.

    I have notice these last few years some ridiculously strange looking clouds, from all these channeled messages and telepathic communications with extra terrestrials it wouldn't surprise me.

    I know this may be beyond crazy for some to believe or comprehend but sooner or later it will all make sense once more of us are ready for first contact. As i kid i always believed in star-trek/star-gate and similar type of shows because the ideas in them were just out of this worldly imagination. Someone must of witnessed something or been somewhere to picture/imagine with such sophisticated ideas and structures that no ordinary human living in earth could just come up with.

    Then again many of the ideas from them shows so many years ago are just now starting to come out in public. Research the Galactic Federation of Light if you are interested. We simply focused way to much on technology instead of inner-abilities which is probably why many of us are blind to this knowledge.

    Telepathy was distracted with Cell phones, Remote viewing was distracted with TV, are some examples. Just ask yourself this: where did people get these ideas from. They must of existed in one point in time or you simply would not be able to imagine it no matter how creative you are. Similar to mythological creatures and what not, they were obviously seen at one point in time for the stories to be passed on.

    Modern culture and society has been heavily conditioned by the general lifestyle to dismiss/reject/ignore all these types of information because they are programmed to believe these things are impossible and fairly tales. Well the more you self educate the more you realized almost everything you been taught was a lie in some way and almost completely backwards.

    The most impossible/unbelievable things are turning out to be true and everything else that we swear by is a man-made illusion only to keep the masses from thinking outside the box and beating the system at their own game. Why? greed, power, material = corrupts. The deeper you go the harder it is to come clean and let go.

    Take the Matrix for example: Its one of the most accurate movies that replicates our current lifestyle with a twist, yet from the average mind heavily conditioned by culture and society, its the complete opposite due to heavy brainwashing by the current systems and it will only become a never ending argument.

    Sorry to go slightly off topic but i just woke up with a blast of downloads needed to be expressed.
    Edit: Just came across this.. Law of attraction huh?
