To construct a Dyson Shell (or Cap), an exceptionally light and very absorptive material would be necessary, because a 20-mile-radius (32 km), 0.4-inch-thick (1 cm) titanium Dyson Shell would have a mass of more than 1,200 Empire State buildings! Alternatively, a Dyson Cap that absorbs radiation that would be fed into a heat engine would have a lower mass, but would also deliver an inferior acceleration.

Furthermore, a gamma-ray laser is currently the only conceivable technology that could be used to make a Schwarzschild Kugelblitz. However, such a laser’s output frequency would need to exceed current technology by more than a billion times. Its pulse duration would have to be a hundred billion times shorter than that of lasers today. The total energy of a single laser pulse would need to be equivalent to the energy the sun puts out in 1/10 of a second.

While it’s true that the technical challenges render it unlikely that a SK will be fueling an interstellar starship anytime soon, it’s imperative that we embrace a wide range of theoretical research. SKs can produce many petawatts of useable radiation; therefore, they hold the potential to be an ideal source of power for interstellar starships. Thus, in time, Schwarzschild Kugelblitzes may merit a position of distinction on the vast technology arc that could one day take us to the stars.

USC Dornsife’s CReATiNG technique revolutionizes synthetic biology by facilitating the cost-effective construction of synthetic chromosomes, promising significant advancements in various scientific and medical fields.

A groundbreaking new technique invented by researchers at the USC Dornsife College of Letters, Arts and Science may revolutionize the field of synthetic biology. Known as CReATiNG (Cloning Reprogramming and Assembling Tiled Natural Genomic DNA), the method offers a simpler and more cost-effective approach to constructing synthetic chromosomes. It could significantly advance genetic engineering and enable a wide range of advances in medicine, biotechnology, biofuel production, and even space exploration.

What an exciting week it has been! We saw the rollout of both Ship 28 and Booster 10 down to the Gateway to Mars launch pad, and Ship 28 has alreadys starting undergoing tests, conducting a spin prime test over the weekend. Elsewhere, we had 3 mysterious launches from China, and strange lack of any Falcon missions, as well as a return to flight for Rocket Lab and Blue Origin. All of this and much, much more. Enjoy!

SpaceX has shared a trio of awesome night shots showing its Super Heavy booster — the most powerful rocket ever built — being rolled to the launchpad ahead of its third test flight.

Look closely at the image above and you’ll see that the transporter carrying the 233-foot-tall (71 meters) booster is bedecked with Christmas decorations, including colorful lights, a tree, and a Santa Claus model. And for scale, take a look at the human captured in the extreme right of the frame.
