alexander based computer describe developed dutch entire hard ideas love mathematics opinion people personal scientist suggest talk using
Many people suggest using mathematics to talk to the aliens, and Dutch computer scientist Alexander Ollongren has developed an entire language (Lincos) based on this idea. But my personal opinion is that mathematics may be a hard way to describe ideas like love or democracy.
basement home lying major pick science scientific somebody waiting
In the 19th century, if you had a basement lab, you could make major scientific discoveries in your own home. Right? Because there was all this science just lying around waiting for somebody to pick it up.
amplifier basement expired graduated high lack magazine nearly people
When I graduated high school, nearly a half-million people subscribed to 'Popular Electronics' magazine. Soldering up some radio or hi-fi amplifier on the basement workbench was not just a personal passion - a lot of young people were doing the same. The magazine expired in 1999 for lack of interest.
amount anyone base beam billion consists few fit four genome human information microwave radio since travel types
Consider: The human genome consists of about 3.3 billion base pairs. Since there are only four types of pair, that amounts to 0.8 gigabytes of information, or about what you can fit on a CD. With a microwave radio transmitter, you could beam that amount of information into space in a few minutes, and have it travel to anyone at light speed.
almost dinosaurs interested kids might science
I think a lot of kids are interested in two science subjects: dinosaurs and aliens. The reason is almost genetic; we're hard-wired to be interested in things that might be a little dangerous.
home intelligence might stay
I think there's a lot of intelligence out there, but that's just my guess. Question is: Are they peaceable or hostile? You could say that the peaceable ones are just going to stay at home and play with their Nintendos, so if you do meet any of them, they might be hostile.
allowing continuing few five perhaps pound thousands
Our brains are continuing to evolve, and perhaps a few tens of thousands of years from now, our descendants will walk around with five pound brains, allowing them insights that we can't imagine.
currently life might planets plate rich scarcely sports venus
Planets that don't currently sport plate tectonics, such as Venus and Mars, are scarcely habitable. Tectonics might be a requirement of any world that aspires to a rich diversity of life.
artificial fact intelligence majority planet
Most of the intelligence out there must be artificial intelligence. We keep looking for critters like us living on a planet like ours, where in fact the majority of the intelligence out there is not biological. That would be my argument.
evidence fluke found life objective whether
We haven't yet found a speck of evidence for biology on another world, so we have no objective way to judge whether life is a onetime fluke or a near-inevitable phenomenon.
brains build good inadequate might perhaps
Sure, our three-pound brains might be inadequate to understand the universe. But perhaps they're just good enough to build something that can.
argue beneath choice hide jupiter life liquid mars number oceans outer remains rock vast
Mars still remains the astrobiology community's number one choice for 'nearest rock with life,' but there are many researchers who argue that the moons of Jupiter are better bets. In particular, Europa, Ganymede, and Callisto are all thought to hide vast oceans of liquid water beneath their icy, outer skins.
cent estimates galaxy latter number occur order per planets rather since solar stars systems
Estimates are that at least 70 per cent of all stars are accompanied by planets, and since the latter can occur in systems rather than as individuals (think of our own solar system), the number of planets in the Milky Way galaxy is of order one trillion.
aftermath bang cosmic cosmos elements enriching heavy inevitably interval planets rocky sterile takes time
Clearly, enriching the cosmos with heavy elements takes a while. So there's inevitably an interval between the sterile aftermath of the Big Bang and a time when the cosmic chemistry set had enough ingredients to make rocky planets (and squishy biology).
