Laser light and star trails combine for a cosmic light show at Gemini North, one half of the International Gemini Observatory which is supported in part by the U.S. National Science Foundation and operated by NSF NOIRLab, on Maunakea in Hawai‘i. This scene was created by combining multiple timelapse images.

In the foreground sits Gemini North, situated near the highest point in the Pacific Basin at an altitude of 4213 meters (13,822 feet). The orange streaks were created by Gemini’s Laser Guide Star (LGS) system at several different observing positions. The laser creates an ‘artificial star’ by interacting with atoms in the upper atmosphere approximately 90 kilometers (50 miles) above the Earth. Earth’s atmosphere distorts light from the laser-created ‘star’, just as it distorts the light from objects under study. By measuring these distortions, Gemini’s adaptive optics system can correct for them in the telescope’s science observations, resulting in crisper, clearer views of the Universe for astronomers.

In the background, stars swirl around Polaris, the northern hemisphere’s pole star. As Earth rotates over the course of a night, stars seem to circle the celestial poles, showing up as trails in long-exposure photographic images.

📸 Savudrija Star Trails
Savudrija lighthouse glows on the Adriatic coast, while Polaris — the North Star — shines above. This stunning composite shows star trails around the North Celestial Pole, captured through 400 stacked 30-second exposures. A perfect blend of Earth and sky in motion.

Long-exposure night photograph of Savudrija lighthouse on the Adriatic coast, with circular star trails filling the sky. The lighthouse stands illuminated near the bottom left, while the stars form concentric arcs centered around Polaris near the top center of the image. The trails create a sense of rotation, emphasizing Earth's movement. The image has a serene and mesmerizing quality, blending coastal architecture with cosmic motion.

#TimeTravelTuesday #ThoughtExperiment: Many #Worldlets?

or in other words, fractions of #World, not the whole World. #TimeTraveler #theories often involve splitting or multiplying #universes. Time Travel events divide #spacetime into two near-identical clones. Grandfather lived or did not, you did not meet yourself or you did. But if we think this through further, its scope might not be quite so universal as typically presented.

Take 3 heavenly bodies: Mother #Earth, the #AlphaCentauri triple star system (at 4+ light years away), and #Polaris, the #NorthStar (at 400+ light years away).

Now we program our #TimeMachine to take us back one year (#retrograde) where we meet ourselves. Hi selves! This all takes place in one year. There's the original us, there's us leaving the present, and there's us meeting our past/original selves a year earlier — standard #boilerplate #scifi #movie #script.

Alpha Centauri will have to wait another 3 years before any of this information can get to there. This is related to the concept of a #lightcone which expands at the speed of light. This doesn't sound quite so much like birthing a twin universe, does it? Now what about the North Star? It will have to wait 433 years for news of our Time Travel event(s). And that's still pretty much in our tiny #celestial neighborhood.

The point is that the effects of such events are largely localized and rapidly diluted as we move farther away. This still has its paradoxical problems, but it doesn't quite feel like the whole universe dividing into two — maybe part of it (a universelet? a subuniverse?) Possibilities are that in moving further out in space-time, the effects of a Time Travel incident may be 'blurred out', as are anomalous numerical samples in the law of large #numbers. If one pours a cup of coffee into a lake, it doesn't change the color of the lake. There is a brief chaotic #glitch before it is no longer measurable.

It is tempting to imagine space-time as "stitching" itself back together. (Glitch & stitch?) Such speculations are related to #StephenHawking's "chronology protection conjecture" of 1992. And along with #blackholes, #entanglement, and other #quantum phenomena, if Time Travel is possible, then we should be looking for it at every scale. We could be surrounded by time-traveling particles everywhere all the #Time.
