Extraterrestrial life physics: aliens should be similar to earthlings

By the end of this century, says astrophysicist Martin Rees, we need to answer the question, we live in a multiverse or not, as well as the laws of physics are different in constituent universes. The answer to this question, according to Rice, will determine "how we should interpret" biodruzhestvennuyu "universe in which we live (and which share with the aliens with whom one can get in touch)". The same fundamental laws are applicable to the entire area that we can investigate with the help of telescopes.

Extraterrestrial life physics: aliens should be similar to earthlings

If this were not the case - if the atoms behaved "anarchic" - we would not have made progress in understanding of the observable universe. But the observed region, says Rice, may be not only the physical nature; Some cosmologists believe that "our" Big Bang was not the only one - and that physical reality is large enough to cover the entire "multiverse."

will look like aliens?

Even conservative astronomers concludes Rees, "convinced that the volume of space-time that is visible to our telescopes - what astronomers usually call" the universe "- is only a tiny part of the consequences of the Big Bang. We suggest that beyond this horizon if the set of unobserved galaxies, each of which (together with intelligent life in it) develops like ours.

Charles Cockell, astrobiologist at the University of Edinburgh, suggests that life on Earth could be a template for life in the universe, comparing it with the standard model constants or life equations.

Regardless of how different conditions on distant planets, all of them, presumably, will have the same laws of physics - from quantum mechanics to thermodynamics and gravity. And life, according to Coquelles, is simply living matter, "the ability to reproduce and evolve." If this biology is everywhere in the universe, we will find it not only surprisingly familiar externally, but also internally, deep in the cellular engineering on the basis of carbon. There are equations and rules, which are not limited to living systems that underlie the functioning of life. These equations, as far as we can tell, the same in the whole universe. To understand how life might look in other places, we only need to study in detail how it works here.

Repetition of evolution, DNA, RNA, ATP and Krebs cycle - the fundamentals of biology - is likely to happen again here or in distant worlds, says George Johnson of New Yorrk Times. Single cells are then reunited again in search of advantages metazoynoy life, unless there is something like our familiar earthly menagerie.

laws of biology repeat the physical laws that are manifested everywhere - gravity, for instance, exists everywhere, not only in our solar system. Restrictions are also ubiquitous - organic molecules on Earth or anywhere else, still decompose at high temperatures and at low deactivated. Certain ingredients, in most cases, are indispensable for life - carbon member is optimal for creating growing life, and water - ideal solvent for its displacement.

We are accustomed to a life that breathes in oxygen and there under the blue sky. Although in nature there are many worlds, similar to our conditions throughout the universe will be very different. And while our equations will work, life will appear in an infinite number of variations - every time different - yet similar, because its development will depend on the equations underlying the physical universe.

"The laws of physics guide sentient beings in a limited way," he says. "They narrow the scope of evolution. Alien life could be a lot to do with life here. " "Go into the ocean," says Cockell. "There exists a thin, sleek bodies - and for some reason, to move faster in the water." This has worked hundreds of millions of years, dolphins, sharks, ichthyosaurs, mammals, fish, dinosaurs became extinct - they were all apparently comparable. Everything looks similar even if different pedigrees.

On land, most animals received limb movement; in the sky, whether blue or pterodactyls, "also observed the laws of aerodynamics." Even butterflies, although in different patterns and colors also have wings, following equation. If the wing is too small, and the butterfly could not fly. Items will be endless, but the physics limits the shape.

Atoms combine to create more complex structures that are designed to capture energy from the surrounding environment and create copies of themselves to continue the process. This formula of life on our planet has worked from the beginning. Why it will not work in other places? Tell us in our chat in the telegram.
