Alien Alert!!! New Study!!!:60billion Planets Could Support Life in Our Galaxy!!!

Spread the love

Recently some astronomers have dramatically increased their estimates of how many planets in our little corner of the Cosmos might fall in the habitable zone around red dwarf stars!  There could be as many as 60,000,000,000 such habitable planets in the Milky Way alone!

Based on data from NASA’s planet-hunting Kepler spacecraft, scientists have predicted that there should be one Earth-size planet in the habitable zone of each red dwarf, the most common type of star. But a group of researchers has now doubled that estimate after considering how cloud cover might help an alien planet support life.

“Clouds cause warming, and they cause cooling on Earth,” study researcher Dorian Abbot, an assistant professor in geophysical sciences at the University of Chicago, said in a statement. “They reflect sunlight to cool things off, and they absorb infrared radiation from the surface to make a greenhouse effect. That’s part of what keeps the planet warm enough to sustain life.” [9 Alien Planets That Could Support Life]

Maybe the Vulcans will show up in Montana after all!

    I wonder if the Creator put some life out there as well, there would be a huge waste of space otherwise…

    Finding 60,000,000 planets isn’t the problem. Getting to one and making it truly habitable for human life is a HUGE problem.

    Waste from whose perspective? The notion of anything being a waste to God is a laughable one. Whether Boltzmann brain or 28 billion parsecs, it’s no matter. Easy peasy all the same. It is entirely possible that the volume and scope of the observable universe is necessary supporting infrastructure for our being.

    “The Privileged Planet” goes over why a red dwarf is the wrong type of star. One reason is its habitable zone is closer and that would put the alleged habitable planet in a tidal lock with the star. One side would always face the star and the other would be facing away.

    No rotation, no magnetic field, means no protection from the stars radiation. The only place there may be liquid water would be at the horizon.

    A red dwarf system would not support metazoans- IOW SETI shouldn’t look towards a red dwarf for ET.

    Notes towards Red Dwarfs:

    New Conditions for Life On Other Planets: Tidal Effects Change ‘Habitable Zone’ Concept – February 2011
    Excerpt: Tides can render the so-called “habitable zone” around low-mass stars uninhabitable. This is the main result of a recently published study by a team of astronomers led by René Heller of the Astrophysical Institute Potsdam (AIP).,,, Finally, tides can cause the rotational period of the planet (the planet’s “day”) to synchronize with the orbital period (the planet’s “year”). This situation is identical to the Earth-moon setup: the moon only shows Earth one face, the other side being known as “the dark side of the moon.” As a result one half of the exoplanet receives extreme radiation from the star while the other half freezes in eternal darkness.

    Overlooked factor suggests fewer habitable planets than thought – Richard A. Lovett – 08 May 2012
    Excerpt: There’s just one problem with finding habitable planets around such stars (red dwarfs), says Barnes. Because tidal forces vary dramatically with the distance between a planet and its star, closer orbits also result in massively larger tidal forces.,,, A similar tidal process makes Jupiter’s moon Io the most volcanic body in the Solar System. “I’m just scaling that Io–Jupiter system up by a factor of 1,000 in mass,” Barnes said at the meeting. “It’s the same process, on steroids.”

    Astrobiology research is revealing the high specificity and interdependence of the local parameters required for a habitable environment. These two features of the universe make it unlikely that environments significantly different from ours will be as habitable. At the same time, physicists and cosmologists have discovered that a change in a global parameter can have multiple local effects. Therefore, the high specificity and interdependence of local tuning and the multiple effects of global tuning together make it unlikely that our tiny island of habitability is part of an archipelago. Our universe is a small target indeed.

    Notes as to size of universe:

    Evidence for Belief in God – Rich Deem
    Excerpt: Isn’t the immense size of the universe evidence that humans are really insignificant, contradicting the idea that a God concerned with humanity created the universe? It turns out that the universe could not have been much smaller than it is in order for nuclear fusion to have occurred during the first 3 minutes after the Big Bang. Without this brief period of nucleosynthesis, the early universe would have consisted entirely of hydrogen. Likewise, the universe could not have been much larger than it is, or life would not have been possible. If the universe were just one part in 10^59 larger, the universe would have collapsed before life was possible. Since there are only 10^80 baryons in the universe, this means that an addition of just 10^21 baryons (about the mass of a grain of sand) would have made life impossible. The universe is exactly the size it must be for life to exist at all.

    God created the entire universe for us – February 2012
    Excerpt: If the sun were represented by the period at the end of this sentence, our galaxy would be the size of the continental United States.,,, Why didn’t God create our modest solar system and a few stars and let it go at that? Because size matters.
    If the universe weren’t as large as it is fusion would be inefficient. As a result, the universe would produce hydrogen, or hydrogen plus a small amount of helium. That means carbon and oxygen — both essential for life — would be missing.

    Does human life even really matter in such an immense universe?

    The Galileo Affair and ‘Life’ as the true “Center of the Universe”
    Excerpt: I find it extremely interesting, and strange, that quantum mechanics tells us that instantaneous quantum wave collapse to its ‘uncertain’ 3D state is centered on each individual conscious observer in the universe, whereas, 4D space-time cosmology (General Relativity) tells us each 3D point in the universe is central to the expansion of the universe. These findings of modern science are pretty much exactly what we would expect to see if this universe were indeed created, and sustained, from a higher dimension by a omniscient, omnipotent, omnipresent, eternal Being who knows everything that is happening everywhere in the universe at the same time. These findings certainly seem to go to the very heart of the age old question asked of many parents by their children, “How can God hear everybody’s prayers at the same time?”,,, i.e. Why should the expansion of the universe, or the quantum wave collapse of the entire universe, even care that you or I, or anyone else, should exist? Only Theism, Christian Theism in particular, offers a rational explanation as to why you or I, or anyone else, should have such undeserved significance in such a vast universe. [15]

    The LORD looks from heaven; He sees all the sons of men. From the place of His dwelling He looks on all the inhabitants of the earth; He fashions their hearts individually; He considers all their works.

    The Scale of The Universe – Part 2 – interactive graph (recently updated in 2012 with cool features)
    http://htwins.net/scale2/scale.....olor=white

    The preceding interactive graph on the scale of the universe points out that the smallest scale visible to the human eye (as well as a human egg) is at 10^-4 meters, which ‘just so happens’ to be directly in the exponential center of all possible sizes of our physical reality (not just ‘nearly’ in the exponential center!). i.e. 10^-4 is, exponentially, right in the middle of 10^-35 meters, which is the smallest possible unit of length, which is Planck length, and 10^27 meters, which is the largest possible unit of ‘observable’ length since space-time was created in the Big Bang, which is the diameter of the universe. This is very interesting for, as far as I can tell, the limits to human vision (as well as the size of the human egg) could have, theoretically, been at very different positions than directly in the exponential middle of all possible sizes;

    Is there a violation of the Copernican principle in radio sky?

    ….Why should there be such large anisotropies present in the sky distribution of some of the most distant discrete sources implying inhomogeneities in the universe at very large scales (covering a fraction of the universe)? What is intriguing even further is why such anisotropies should lie about a great circle decided purely by the orientation of earth’s rotation axis and/or the axis of its revolution around the sun? It looks as if these axes have a preferential placement in the larger scheme of things, implying an apparent breakdown of the Copernican principle or its more generalization, cosmological principle, upon which all modern cosmological theories are based upon.

    The science behind northern lights – October 2, 2012
    Excerpt: ,,,(solar) flares release a burst of charged particles, or plasma, into the solar system. When they come our way, they whack into the Earth’s magnetosphere, which is made up of its own stream of charged particles. That collision causes particles to break free of the magnetosphere and cascade toward the Earth’s magnetic field lines, usually traveling toward the poles. “The aurorae happen when these high-energy particles bap into atoms and molecules in the Earth’s atmosphere, typically oxygen,” Nemiroff said. Light is emitted as part of the reaction. Those particles can also wreak havoc. “The plasma cloud can cause the Earth’s magnetic field to fluctuate,” Nemiroff said. “At worst, that can knock out satellites and even power grids.”,,,
