The colony drop from Gundam The Origin movie. The structure is 4.5 billion tons striking at nearly 11 km/s. That's 65 gigatons of energy. Its sectional density is 139 tons/m^2, meaning it would easily get through the 10 tons/m^2 atmosphere.

This is how fast Earth flies through the galaxy. The solar system, including Earth, revolves around the center of the Milky Way at a speed of about 230 km/s. At first glance, this seems impressive. But when compared to the diameter of our planet (approximately 12,750 km), on a cosmic scale, it all looks almost like slow motion.

Can Venezuela withstand the attack after Trump's green light? Initially, the targets would be Venezuelan radars, which would be attacked by American drones, disabling the anti-aircraft defenses. Venezuela does not have a dedicated drone interception system, which could be a crucial vulnerability. Iglas and RBS 70 are the only options to attack drones flying at max 5,000m altitude.

Yemen has far less against a much larger task force and still made a significant impact. The defense systems as S300VM, Buk-2M and Pechoras were deployed around several cities.

🚨🇷🇺The ATACMS and Storm Shadow are now useless: Russia has upgraded its Pantsir M System Spotted in Ukraine, the modernized Pantsir-S1M represents a radical evolution in Russian air defense, effectively transforming a point-defense system into a medium-range contender. The key is its new, combined arsenal. It retains standard 57E6 rockets but now deploys new 57E6M hypervelocity missiles reaching Mach 5 with a 35+ km range. Coupled with a radar twice as powerful, it can detect targets like the F-16 from 60 km away. Performance against key threats like HIMARS rockets has doubled. Engagement range jumped from ~8 km to over 13 km. Critically, its max target speed is now 2,000 m/s—a figure approaching the Patriot PAC-3's 2,200 m/s capability, despite a vast cost difference. The upgrade includes a kinetic hit-to-kill warhead and enhanced anti-jamming systems. When networked, it can challenge a vast spectrum of Western munitions—from Storm Shadow cruise missiles to ATACMS ballistic rockets and drone swarms.

O-train line 2 and line 4 are really something else. The trains are incredibly smooth quiet very low vibration even when they’re moving at 80 km an hour on the high speed stretches. Big spacious and warm. The stations themselves also are very fun to explore with a lot of glass.

2034 Earth–Venus–Mars opportunity looks promising. 10–15 on-orbit refueling operations may be needed to make a crewed ship full. Most can be done at an altitude of 180–200 km, made possible by Starship’s size. The final refueling may be performed at a higher altitude of ~2000 km, just below the Van Allen belt. Earth departure on 2034-08-21 from 2000 km orbit. A Trans-Venus Injection burn of ~3.7 km/s will place the ship on an Earth–Venus–Earth free-return trajectory. Venus flyby is expected on 2034-12-19, 120 days after departure. Two weeks before the encounter, if the mission proceeds as planned, a 25-m/s maneuver will shift the trajectory from Earth-return to Mars-bound. If not, the ship will free return to Earth in September 2035. The Venus gravity assist will send the ship into another Earth free-return trajectory, with Mars flyby around 2035-06-02. One week before reaching Mars, a system health check will determine whether to commit to Mars Orbit Insertion. If it’s GO, a small 10-m/s manuever will put the ship to less than 100 km altitude periapsis. Otherwise, a Mars flyby will lead to an Earth return in May 2036. The ship will enter the Martian atmosphere at about 9.4 km/s, performing an aerobrake to slow to 4.88 km/s and capture into a 100x140000 km, 7-day period high elliptical orbit. At apoapsis, a 50-m/s plane change will align the inclination with Mars’ equator, followed by additional aerobraking to remove about 650 m/s of velocity, placing the spacecraft in a 120x6128 km orbit. A 550-m/s burn at 6128 km altitude will then adjust the trajectory into Phobos orbit. The ship will stay at Phobos for about 7 days. The Mars–Phobos L1 point is only about two miles above Phobos’ surface, and Mars would dominate nearly half the sky, appearing about 80 times larger than the Moon from Earth. The ship will depart for Deimos afterward. Two burns totaling roughly 750 m/s will transfer the ship from Phobos to Deimos. And the ship will stay at Deimos for 7 days more. From Deimos, the ship will raise its apoapsis to form a 20000x140000 km altitude, 7-day orbit, requiring about 420 m/s of delta-v. At apogee, a 50-m/s burn will adjust inclination and lower periapsis to ~500 km for final Trans-Earth Injection. If time and propellant allow, the orbit can be aligned to a polar inclination for Mars ice-cap observations before departure. A Trans-Earth Injection burn at 500 km altitude, requiring 1.5–1.6 km/s of delta-v in early July 2035. If departure on the first days in July, Earth arrival is expected in December 2035. If missed that window, a March 2036 arrival may look more feasible. Nominal mission duration: 490 days, with 30 days in Mars orbit and 14 days at Phobos and Deimos.

Scientists mapped a piece of brain the size of half a grain of rice. One-millionth the size of the human brain. It took them a year and over 1.4 million gigabytes to scan it. They found over 57,000 cells, 150 million synapses, and even some new structures they didn't know existed. Mapping the entire human brain in this level of detail would require all the data storage generated on Earth in a year + a 140-acre data center. But the human brain itself can hold up to ~2.5 million gigabytes of information - enough for ~3 million hours of HD video or 342 years of continuous viewing. It can process roughly 10 quadrillion calculations per second - enough processing power to run over 4,000 high-end gaming PCs all operating at peak ability. And it only runs on the amount of power needed for a single dim light bulb. No technology even comes close to doing what the brain can do. The more we learn about biology, the more complex it becomes. This is God's Glory on display.

🇨🇳 CHINA'S MAGLEV HITS 700 KM/H IN 2 SECONDS - PLANNING 1,000 KM/H - WHILE AMERICA ARGUES ABOUT FIXING POTHOLES China just tested a maglev platform that accelerates to 700 km/h (435 mph) in 2 seconds. Target speed: 1,000 km/h (621 mph). That's faster than commercial aircraft. On the ground. The acceleration alone is borderline violent - 0 to 435 mph in two seconds is 9.8g. Fighter jet territory. Passengers would need specialized seating just to survive the launch. But let's address reality: This is a test platform. Prototype speeds don't mean operational trains. China announces ambitious projects constantly. Some materialize (their existing 430 km/h maglev in Shanghai works). Others disappear quietly. The pattern though? They're attempting scale nobody else is. High-speed rail connecting every major city. Maglev research pushed to extremes. Infrastructure spending that makes Western investment look microscopic. Meanwhile in America: Amtrak averages 105 km/h between cities. California's high-speed rail project started in 2008, burned $10+ billion, and hasn't moved a passenger. The fastest train in the U.S. hits 240 km/h for exactly one 54-mile stretch. China's going for 1,000 km/h. Even if they only achieve 800 km/h operationally, that's still triple America's maximum. Here's why this matters beyond trains: Infrastructure capacity signals industrial capability. If China can build and operate 1,000 km/h trains, they can manufacture the precision components, power systems, and control mechanisms that transfer to aerospace, military, and manufacturing. The U.S. won the 20th century partly because it built the Interstate Highway System when others couldn't. China's betting the 21st century winner will be whoever builds impossible infrastructure first. They might fail. Engineering challenges at 1,000 km/h are extreme - air resistance, track precision, emergency braking, passenger safety. But they're trying while America argues whether to fix the L train in New York. Even Chinese failure puts them ahead. You learn more from attempting the impossible than from successfully maintaining mediocrity. Source: Xinhua, CGTN

🇨🇳 CHINA'S MAGLEV HITS 700 KM/H IN 2 SECONDS - PLANNING 1,000 KM/H - WHILE AMERICA ARGUES ABOUT FIXING POTHOLES China just tested a maglev platform that accelerates to 700 km/h (435 mph) in 2 seconds. Target speed: 1,000 km/h (621 mph). That's faster than commercial aircraft. On the ground. The acceleration alone is borderline violent - 0 to 435 mph in two seconds is 9.8g. Fighter jet territory. Passengers would need specialized seating just to survive the launch. But let's address reality: This is a test platform. Prototype speeds don't mean operational trains. China announces ambitious projects constantly. Some materialize (their existing 430 km/h maglev in Shanghai works). Others disappear quietly. The pattern though? They're attempting scale nobody else is. High-speed rail connecting every major city. Maglev research pushed to extremes. Infrastructure spending that makes Western investment look microscopic.

The fastest star in the Galaxy is S4714, which accelerates to approximately 24,000 km/s at its peak, or about 8% the speed of light. It orbits the supermassive black hole Sagittarius A* at the center of our Milky Way, moving in an extremely eccentric orbit. At its closest approach, it comes to a distance of approximately 1.8 billion km from the black hole—comparable to the distance from the Sun to Saturn. From this distance, the angular size of the "shadow" of Sagittarius A* is four times larger than the angular size of the Sun in Earth's sky! Observations of S4714, conducted with the European Southern Observatory, are helping to test the effects of general relativity in the extreme gravity of the Galactic center.
