Is it possible for intelligence to evolve in the universe?
The universe is large, and old, with time and room for intelligence to evolve, but there’s no evidence of it. Could intelligence simply be unlikely to evolve? Unfortunately, we can’t study extraterrestrial life to answer this question. But we can study some 4.5 billion years of Earth’s history, looking at where evolution repeats itself, or doesn’t.
Are humans the only intelligent life in the universe?
Humans May Be the Only Intelligent Life in the Universe, If Evolution Has Anything to Say By Nick Longrich October 22, 2019 We may be utterly alone in the universe.
What are the odds of evolution of intelligence?
The odds of evolving intelligence become one in 10 million. But complex adaptations might be even less likely. Photosynthesis required a series of adaptations in proteins, pigments and membranes. Eumetazoan animals required multiple anatomical innovations (nerves, muscles, mouths and so on).
How did humans evolve without the evolution of life?
Humans couldn’t evolve until fish evolved bones that let them crawl onto land. Bones couldn’t evolve until complex animals appeared. Complex animals needed complex cells, and complex cells needed oxygen, made by photosynthesis. None of this happens without the evolution of life, a singular event among singular events.
Could there be life in a 2-D universe?
Researcher shows physics suggests life could exist in a 2-D universe. James Scargill, a physicist at the University of California, has written a paper reporting that the laws of physics allow for the existence of a life-supporting two-dimensional universe.
Is there life on other planets in the universe?
The universe is astonishingly vast. The Milky Way has more than 100 billion stars, and there are over a trillion galaxies in the visible universe, the tiny fraction of the universe we can see. Even if habitable worlds are rare, their sheer number — there are as many planets as stars, maybe more — suggests lots of life is out there.
