"Astronomers will have scanned enough star systems by 2040 that we’ll have discovered alien-produced electromagnetic signals," said Seth Shostak of the SETI (Search for Extraterrestrial Intelligence) Institute in Mountain View, Calif. during a talk at the 2014 NASA Innovative Advanced Concepts (NIAC) symposium at Stanford University.
SETI has until now sought radio signals from worlds like Earth. In the current search for advanced extraterrestrial life SETI experts say the odds favor detecting alien AI rather than biological life because the time between aliens developing radio technology and artificial intelligence would be brief. “If we build a machine with the intellectual capability of one human, then within 5 years, its successor is more intelligent than all humanity combined,” says Seth Shostak, SETI chief astronomer. “Once any society invents the technology that could put them in touch with the cosmos, they are at most only a few hundred years away from changing their own paradigm of sentience to artificial intelligence,” he says.
ET machines would be infinitely more intelligent and durable than the biological intelligence that created them. Intelligent machines would be immortal, and would not need to exist in the carbon-friendly “Goldilocks Zones” current SETI searches focus on. An AI could self-direct its own evolution, each “upgrade” would be created with the sum total of its predecessor’s knowledge preloaded.
ET artifacts coordinated by computers, suggests British physicist, Stephen Wolfram, would look far more like a natural artifact. It is easy to distinguish a technological artifact such as a car from a natural object such as a tree. The tree is far more complicated. But, says Wolfram,”this is simply because our technological artifacts are primitive. As they become more complex - with computer processors enabling them to make a moment-by-moment decisions - they will begin to look just as complex as trees and people and stars.” We have slim chance, he suggests, of distinguishing an ET artifact from a natural celestial object.
I laughed out loud at #14 because I couldn’t help but think:
This is HOT! Having your buddy drop his load for you to use as lube as you are fucking your wife’s ass!
Using sound waves to levitate individual droplets of solutions containing pharmaceutical drugs and drying them in mid-air. Why do this? This is useful because most of the drugs on the market are either amorphous or crystalline and the crystalline form doesn’t get absorbed by the body. So levitating the solution allows the drug to be made into an amorphous state (by evaporation) because if it were to touch any surface it would simply crystallize. They call this “containerless processing”.
The frequencies used are just above the audible range at about 22 kilohertz and when the two speakers are aligned they create two sets of sound waves, perfectly interfering with each other creating a phenomenon known as a standing wave. This allows the objects to levitate in areas within the waves known as nodes as the acoustic pressure is enough to cancel the force of gravity.

This is little Mykayla Comstock.
Mykayla is 7.
Mykayla’s been battling leukemia since June, when doctors discovered a basketball-size tumor in her chest.
To cope with the debilitating symptoms associated with her traditional cancer treatments, Mykayla consumes a gram of cannabis oil every day.
She also likes the way cannabis makes her laugh. “It’s like everything’s funny to me,” she tells us. Her mom, facing critics, wants you to know she isn’t drugging her child.
“I use this for her medicine,” she says. “It’s amazing, and I think people should know that.”
the human heart and the earth have the same electromagnetic frequencies also
