Berezow: 'we will never meet intelligent aliens'

Science writer Alex Berezow has offered a damning verdict on the odds of us ever meeting ET face-to-face.
The question of whether we are alone in the universe remains one of the biggest philosophical conundrums of our time. While it seems almost inconceivable that our civilization is alone in the cosmos, the fact still remains that we have yet to see any evidence to the contrary.

For some, however, the question isn't so much whether or not intelligent alien civilizations exist, it is whether or not there is any chance that we are ever likely to come into contact with them.

Science writer Alex Berezow, who is the executive editor of Big Think, accepts the likelihood that aliens do exist but believes that there is next to no chance that we will ever meet them.

"Thanks to advances in astrophysics, we now know that there are billions of exoplanets in the Milky Way alone, leading most of the scientific community to conclude that life probably does exist elsewhere in the universe," he said. "Those who do not believe so are now considered the kooks."
His main argument against the likelihood of coming into contact with such beings is simply that space travel across such vast distances is totally impractical.

"Sure, we could get on a spaceship today and head for a planet orbiting the nearest star, Proxima Centauri, but we better pack a lot of fun-sized bags of pretzels because it will take about 6,300 years to get there," he said.

While this argument does seem sound, it also implies that we will never develop advanced spacefaring technology or make a discovery that could make interstellar space travel easier.

Until that happens, though, it's unlikely that we'll be visiting any alien worlds anytime soon.

Not sure what youmean. Evolution would occur, but would be much more uniform if all life experienced very similar conditions In a very benign environment, it is possible that evolution would proceed more slowly than under challenging or changing conditions

These aren't my predictions the y are those of people like Carl Sagan and astrophysicists etc. Plus of course writers of speculative fiction who base their stories on science . quote Part 3: What if ... the supercontinent Pangaea never broke up? From about 300 million to 200 million years ago, all seven modern continents were mashed together as one landmass, dubbedPangaea. The continents have since "drifted" apart because of the movements of the Earth's crust, known as plate tectonics. Some continents have maintained their puzzle piece-like shapes: Look at how eastern South America tucks i... [More]

A wether can not breed; so, wether patterns would hinder ovine evolution.

Anyone, a mechanic, a doctor, a cook, who approaches this with some amount of facts and logic can argue that we will not be meeting intelligent ET's much more effectively than those that argue the opposite in my experience. The opposite requires stretches of the imagination and relies on sci-fi models of science. If you only argue what we know for sure it does not seem to be a realistic proposition. If anyone thinks they have an effective argument that we will be meeting intelligent ET's I would love to hear the reasoning.

There must be life on other planets among the millions of stars , but we shall probably never know as it will not exist in human form as our planet is unique . The atmosphere's cannot be identical to us , therefor they would have evolved differently . Their communication systems will be different , for example :- if dinosaurs were the dominant species ,could we communicate with them , and without some form of "hands" they could not begin to build anything , as we are able to do. As far as visiting other planets it's not possible unless we have the means to survive the impossibly long journey's... [More]

Hi Walker We can't change the past of evolution so we have to accept the physical differences but then most wars are about opposing ideologies and possessions
Comment icon #52 Posted by Mr Walker 3 months ago
In part true, and i did mention that my hypothetical world had plenty of well distributed resources Different ideologies are less likely to evolve where there is only one language or one set of customs That is more likely to occur where people are not separatedby water, mountains deserts etc Evolution is a process dependent on environmental conditions While it will always occur, it may shape a world ( including the people of that world ) in very differentways given a different environment Because all self aware beings have a unique world view, it is possible that differing religion...

A reasonable but pessimistic view It is also possible that some of the planets would have earthlike conditions Intelligence may require abilty to manipulate objects, as well as language Translation of language might be difficult but not impossible with modern computers There are many diverse beliefs and groups on earth which would prepare us for understanding the diversity on otherplanets Ps it once took 6 months to get from Britain to Australia by ship (much longer if you tried to walk it ) Now we can do it in less than 24 hours Distance is relative, and dependent on speed of trav...

Ewe said It. Now I feel sheepish, like a lamb to the slaughter. No need to ram it home Ps Spelling online is in generally so bad, that I didn't get your deliberatepun. It fleeced me entirely. You pulled the wool over my eyes. Oy vey, ovine, indeed.
