The Laws of Probability Tell Us That the Universe Should Be Teeming With Intelligent Life Forms
Universe could actually be teeming with alien life following THIS discovery
Right now the race is on to directly find amino acids elsewhere in the solar system. Some hints that they abound have been found on meteorites that have landed on Earth from outer space, as well as from missions such as NASA's Stardust probe, which sampled the coma of comet Wild 2 in 2004.
"All signs are that amino acids are going to be found throughout the galaxy," Freeland said. "They are apparently obvious building blocks with which to construct life. What we're finding hints at a certain level of predictability in the way things turned out."
An energy analysis by Ralph Pudritz, a theoretical astrophysicist and director of the Origins Institute at McMaster University shows that the first ten amino acids are likely to form at relatively low temperatures and pressures, and the calculated odds of formation match the concentrations of these life-chemicals found in meteorite samples.
They also match those in simulations of early Earth, and most critically, those simulations were performed by other people. The implications are staggering: good news for anyone worried about how we're alone, and bad news for anyone who demands some kind of "Designer" to put life together - it seems that physics can assemble the organic jigsaw all by itself, thank you very much, and has probably done so throughout space since the beginning of everything.
The study indicates that you don't need a miracle to arrive at the chemical cocktail for early life, just a decently large asteroid with the right components. That's all. The entire universe could be stuffed with life, from the earliest prebiotic protein-a-likes to fully DNAed descendants. The path from one to the other is long, but we've had thirteen and a half billion years so far and it's happened at least once.
Today's Feature: Is Earth's DNA Unique or a Universal Constant?
Given that how could we make an assumption they don't exist ?.
The laws of probability favor alien life, and we've apparently found the building block chemicals in meteorite samples.
No one can prove they do or don't exist, but the laws of probability favor a yes answer imo.
