Dark Matter --Could It Play a Role in Creating Life in the Universe? (2012 Most Popular)




Dark matter makes up the majority of mass in our universe. However, we cannot directly measure the stuff as it doesn't interact with electromagnetic radiation (i.e. it doesn't emit or reflect any light), but we can indirectly observe its presence. In the Hubble Space Telescope image above, the distribution of mostly dark matter has been calculated and mapped. Basically, the location and density of anything with mass has been plotted in a 3D representation of the cosmos.

A 2011 study suggests that mysterious, invisible dark matter could warm millions of starless planets in regions such as Abell 1689 (image below) and make them habitable.
Scientists think the invisible, as-yet-unidentified dark matter which we know exists because of the gravitational effects it has on galaxies, makes up about 85 percent of all matter in the universe.  Current prime candidates for what dark matter might be are massive particles that only rarely interact with normal matter.
These particles could be their own antiparticles, meaning they annihilate each other when they meet, releasing energy. These invisible particles could get captured by a planet's gravity and unleash energy that could warm that world, according to physicist Dan Hooper and astrophysicist Jason Steffen at the Fermi National Accelerator Laboratory.
Hooper and Steffen's propose that rocky "super-Earths" in regions with high densities of slow-moving dark matter could be warmed enough to keep liquid water on their surfaces, even in the absence of additional energy from starlight or other sources.The density of dark matter is expected to be hundreds to thousands of times greater in the innermost regions of the Milky Way and in the cores of dwarf spheroidal galaxies than it is in our solar system.

The scientists concluded that on planets in dense "dark-matter" regions, it may be dark matter rather than light that creates the basic elements you need for organic life without a star"

Dark matter, the team believes, could keep the surfaces of such warm for trillions of years, outliving all regular stars and may ultimately prove to be the "dark" bastion of life in our universe.

"I imagine 10 trillion years in the future, when the universe has expanded beyond recognition and all the stars in our galaxy have long since burnt out, the only planets with any heat are these here, and I could imagine that any civilization that survived over this huge stretch of time would start moving to these dark-matter-fueled planets," Hooper said in an interview with space.com.

well it does create dimensions~

So now this theory is stating you might not even need a parent star, to create a habitable world. That is very interesting, and it seems like every new thing we theorize or learn threw direct observation about our universe, tells us that life in simple forms at least seems to be a natural product of the universe we live in. If a planet does not even need a star or a solar system to attain both the materials and the means to foster development of the building blocks of life. Then I would expect our universe to be teaming with all forms of life in all stages of development.

Myšlenky si zde uvedené i bude diskutovat o extrémně vzácné. Ukázalo se, že opravdu příjemný překvapení pro získání předvídání mě poté, co jsem se probudil dnes. Jsou neustále na jeviště a snadné být vědomi. Díky spousta hodnotných myšlenek, které jste dostali sdílených níže.

let`s just talk about this after we find the first extraterestrial simple life form . Until than let`s focus on the planetary systems that we barely see 5 light years away from us. That place they talk about, is so far that we could even barely or not at all even see red dwarf stars, that could really swarm there. Why immediately assume there are small matter-antimatter (or dark matter - antidark matter) explosions there to warm the place ?

The whole point about dark "matter" is that it isn't "matter" at all, it does not exist in our universe. I haven't yet seen a better explanation of what it actually is than the postulation that it is a "sea" of positive and negative charges which only become "matter" when they interact with one another (much like the chances of atomic nucleii interacting with each other, not very likely at all, but does happen). A positive and negative charge interact with each other (go into orbit round each other) thus creating angular momentum and mass. Reg Mundy in "The Situation of Gravity" calls the positive charges t+rds and the negative charges t-rds, but despite his dubious sense of humour this is a serious proposition, and the only one I have seen which is at all convincing.

So far the only concrete thing we know - Earth has life, and Mars likely had life before.

Mars is an echo of the past, and Earth is all we have right now.
Let's focus on maintaining the only planet which may have life.
