I live on a boat and write as I sail slowly around the world. Follow me for a varied story diet: true stories, humor, tech, AI, travel, geopolitics and more. I also write techno thrillers, with six to my name. More of my stories on Medium
Largest Detected Cosmic Explosion 8 Billion Light Years Away
The headline image is of the oldest documented observation of a supernova (related to but not the subject of this story). This image combines data from four space telescopes to create a multi-wavelength view of all that remains of RCW 86, the oldest documented example of a supernova. Chinese astronomers witnessed the event in 185 A.D., documenting a mysterious "guest star" that remained in the sky for eight months. X-ray images from NASA's Chandra X-ray Observatory and the European Space Agency's XMM-Newton Observatory were combined to form the blue and green colors in the image. The X-rays show the interstellar gas that has been heated to millions of degrees by the passage of the shock wave from the supernova.

If there’s a political vacuum then power will fill it. In a deft diplomatic flanking move, China is strengthening its ties with former Soviet Central Asian republics Kazakhstan, Kyrgyzstan, Tajikistan, Uzbekistan and Turkmenistan.
Mystery of Maya 819 Day Calendar Finally Decoded
If you are an inveterate clock-watcher or diary maniac, then this story might be of interest. I used to be ‘clinically obsessed with time’ according to my sister, but now I’m a bit more relaxed as I live on a boat and don’t usually know what day it is.
Thought Experiments are not Dead, I think
Thought experiments are mental exercises that allow individuals to explore hypothetical scenarios and test their intuitions and beliefs about the world. They have been used for centuries by philosophers, scientists, and other thinkers to gain insights into various fields of study, from physics and mathematics to ethics and metaphysics.
Do we Really Need Terahertz Cellphones and Holograms?
Do We Need 6G Cellphones, Terahertz Tech and Wireless Backhaul? Tinfoil time? Yes, it's really very geeky. The world of wireless communication is evolving at a rapid pace, and as we move towards an even more connected future (God forbid!), the demand for faster, more reliable, and more efficient communication technologies continues to grow.
