Radio SETI is pretty much doomed to failure, but that doesn't mean advanced extraterrestrial intelligences (ETIs) aren't transmitting other signatures that could potentially indicate their existence. Take laser pulses, for example. Unlike radio waves that suffer a dissipative effect the further out they travel, lasers can traverse extreme distances and still remain highly focused and detectable.

This is the assumption of a growing movement in SETI circles called optical SETI (OSETI). Rather than listen for incoming radio signals, these scientists are scanning the heavens in search of deliberate light patterns that may reveal the existence of ETIs.

And now news out of Australia indicates that an OSETI adherent may have actually found something. Astrophysicist Ragbir Bhathal from the University of Western Sidney recently detected a series of mysterious pulses that has him wondering if somebody isn't at the other end.

Bhathal picked up the signal in December 2008 and has been studying the data ever since. He wants to be sure that it's not natural phenomenon (similar to a pulstar) before he jumps to any conclusion. Moreover he hasn't been able to re-detect the signal despite his daily efforts to do so; he is methodically scanning the area in hopes of of finding it again.

But Bhathal has the initial data set and his hope is to put together a peer reviewed paper some day. He may be on a wild goose chase, but his efforts show that novel approaches to SETI are certainly in order.

"NASA is already using lasers for space communication and it's not unrealistic to imagine that an extraterrestrial intelligence might be using them as well," he says. "In terms of Earth technology today, we have achieved a maximum of 10x15 watts of laser power for a brief period, but an advanced civilization could have lasers with powers of 10x25."

He admits, however, that our failure to pick up any interstellar signals so far could mean that advanced civilizations are using a communications technique still not discovered on Earth. "It is risky to judge everything by our own technology," he says.

Fragile Existence by Alex Brown

testing by Beth Scupham

"Our existence is finite. The self that we have created through so many years of effort and suffering will die. And sustained though we may be by the idea, the hope, the certainty that some portion of us will eternally endure, we also must acknowledge that this "I" who breathes and loves and works and knows itself will be forever and ever and ever . . . obliterated.

So, whether or not we live with images of continuity - of immortality - we also will have to live with a sense of transience, aware that no matter how passionately we love whatever we love, we don't have the power to make either it, or us, stay."

- Judith Viorst

Threads of Existence by Snapnpiks

A hyperrealistic surreal portrait of a young woman standing among shelves of colorful yarn balls. Her entire body and outfit are seamlessly made of flowing, three-dimensional strands of yarn in vivid rainbow hues—red, blue, green, yellow, orange, and violet. The yarn wraps tightly around her form, creating mesmerizing patterns that emphasize her elegance and symmetry. Her hair transforms into a radiant crown of coiled yarn, resembling both a headdress and a halo of creativity. Her piercing turquoise eyes contrast with the explosion of color surrounding her. The atmosphere radiates artistry, craftsmanship, and surreal fashion. Ultra-detailed, high-definition textures, cinematic lighting, 4K photography aesthetic.
