Kugelblitz! Powering a Starship With a Black Hole

Posted by in categories: cosmology, space travel

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.

Ships rerouted by Red Sea crisis face overwhelmed African ports

Posted by in category: drones

CAPE TOWN, Dec 22 (Reuters) — Shipping companies sailing around the Cape of Good Hope to avoid Houthi attacks on the Red Sea face tough choices over where to refuel and restock, as African ports struggle with red tape, congestion and poor facilities, companies and analysts say.

Hundreds of large vessels are rerouting around the southern tip of Africa, a longer route adding 10–14 days of travel, to escape drone and missile attacks by Yemeni Houthis that have pushed up oil prices and freight rates.

The attacks by Iranian-backed militants have disrupted international trade through the Suez Canal, the shortest shipping route between Europe and Asia, which accounts for about a sixth of global traffic.

HughesNet’s fast satellite plans rivals Starlink, hitting 100 Mbps

Posted by in categories: internet, satellites

HughesNet’s move to offer 100 Mbps speeds brings it closer to its industry rival, SpaceX’s Starlink, which ranges between 25 to 220 Mbps.

HughesNet’s Jupiter 3 satellite, although geostationary and considerably farther away, rivals Starlink with its size and capacity. The ultra-high-density satellite operates in Ka-band frequencies with 300 spot beams, efficiently allocating and directing signals for better coverage.

Hughes, a pioneer in satellite-delivered internet service since the 1990s, continues to earn recognition.
