THIS IS A FUTURE NETWOK BASED ON HUMAN  consciousnesses   as you can see a beam of network already present in our cosmos some humans have a capability to intract with this system Tellis is a scientist at the University of California at Berkeley, where, as his LinkedIn biography puts it, he spends his days “trawling” astronomy datasets for statistical deviations, trying to figure out whether they’re actually extraterrestrial pings. He searches particularly for laser light, powerful pulses of photons that could be as short as a nanosecond. Tellis, along with astronomer Geoff Marcy, recently dug into the Keck archives for data from 5,600 stars, observed between 2004 and 2016. Tellis and Marcy built a laser-detecting computer algorithm to comb through all that recorded starlight—and the result, detailed in a recent study in the Astronomical Journal, is the largest survey of its kind in the field of optical-based searches for extraterrestrial life. Astronomers and engineers have spent that time developing more powerful technology to conduct SETI surveys. The majority of SETI searches have relied on radio telescopes, which scour the skies for signals in the radio and microwave parts of the light spectrum. In the 1960s, “lasers were new, tricky, low-power devices; by contrast, radio technology had been developing for decades and was relatively mature,” according to a history from the SETI group at Harvard.

These days, lasers can outshine the sun, albeit in tiny pulses. But a tiny pulse—preferably more than one, to prove it’s not a fluke—is all it would take for a distant, advanced civilization to tell Earth “hey, we’re here!” If humans can get really good at sending radio and laser signals, the reasoning goes, maybe intelligent civilizations beyond Earth can, too—and then send them our way.Unlike radio SETI, optical SETI looks for signals in the visible portion of the light spectrum. Lasers travel well over galactic distances. The light, concentrated into a narrow beam that can be 10 times as bright as the sun, would experience less interference from interstellar dust and gas than radio waves might. Laser emissions are also capable of carrying massive amounts of information. The network of cables at the bottom of the ocean is a collection of pulses of light, firing at high frequencies to transmit digital data and bring us the internet.The dataset Tellis used for his study contained thousands of observations of stars as young as 200 million years and stars as old as nearly 10 billion years. Keck’s instruments collected millions of photons of light from these stars.he story behind the invention of the laser typically goes like this. Theodore Maiman, a 32-year-old physicist working at the Hughes Research Laboratories in California, built the first working prototype in 1960. The heart of this device, a synthetic ruby crystal that emitted red light, exploited the new science of quantum mechanics describing a nano-verse of photons, electrons, and other particles. Today, researchers and engineers have developed the technology into models ranging from the gentle red spot of a laser pointer to the behemoth x-ray laser in Germany called the European XFEL, which produces light more intense than all of Earth's solar radiation focused onto a fingertip.But the laser, it turns out, is not uniquely a product of human engineering. "It would be more exact to say that ... lasers have not been invented but discovered," writes physicist Mario Bertolotti in his 2004 book, The History of the Laser.

indeed, as a series of astronomical observations would confirm beginning as early as the 1970s: lasers exist in nature.Experts dispute which astronomical object qualifies as the first discovery of a natural laser. But one oft-cited observation is the 1976 discovery of unusually bright infrared light in the atmospheres of Mars and Venus. Led by Nobel laureate Charles Townes, a group of University of California, Berkeley astronomers deduced that atmospheric carbon dioxide produced this light, and that it brightened and dimmed in sync with sunrise and sunset.

This light, as confirmed by NASA-affiliated researchers in the 1980s, was amplified via the same mechanism that a lab laser produces a beam. They determined this using further observations and models of atmospheric processes on the two planets. In a 1981 paper in Science, they wrote that Mars's infrared light was, to their knowledge, "the first definite identification of a natural infrared laser."Unlike lab lasers, however, these natural ones did not form clearly defined beams. Instead, the light resembled a diffuse glow. If you photographed Mars's horizon with an infrared camera, the laser "would look like a bright edge to the planet," says NASA astrobiologist Michael Mumma, who helped confirm the two planetary lasers. Analyzing the vertical profile of the light from the ground to the sky, they found that the glow peaks in brightness 75 kilometers above Mars's surface.

Still, Mumma's team referred to the glows as lasers because of how they produced light. The letters of the word "laser" refer to this mechanism: light amplification by stimulated emission of radiation. Some circumstance in Mars's atmosphere, just like in a lab laser, amplified the light like a photon megaphone.The amplification involves the interaction between two key components known as the pump and the gain medium. The pump is the energy source that fuels the amplification: Maiman's pump was a xenon lamp, while the planetary lasers run on sunlight, which is why the amplified light exists only in the planets' daytime regions. The gain medium is a material that absorbs the pump's energy to emit light. Maiman's was his ruby crystal, while Mars's and Venus's consist of carbon dioxide molecules. as i DR SUNNY Faridi always see this is big breaking point in tech humans
