We landed on the Moon. Frame-by-frame analysis of the dust coming off the Lunar Rover at the speed and trajectory shown on video from the Moon proves the Rover was in 1/6th the gravity of Earth [1]. There was no way for that 1/6th gravity to be faked on Earth in 1971. Incidentally, probes recently sent to the Moon show where the Lunar Rover made paths in the dusty surface of the Moon, and those paths align with the original video from the early 1970s.
Flat Earth only has a handful of anecdotal short-range observations of some flat areas of Earth taken from a perspective near ground level. Relative to the size of the Earth, those short-distance observations are dominated by the margins of error in the observation. All of those sight lines are accounted for in LIDAR scans of the Earth as well as the WGS84 model.
For less than $1,000 you can send a high-altitude balloon up to see the slight curvature of the Earth. For a few thousand dollars, you can circumnavigate the Earth in an airplane along a common latitude. For tens of thousands of dollars you can go to Antarctica and see the 24-hour Sun from November to January. Or you could just have all your friends from around the globe point to the Sun and measure that angle. With basic trigonometry, you can see the Sun is about 92 million miles away.
> Jetoptera is developing VTOL (Vertical Take-Off and Landing) aircraft that use a "Fluidic Propulsion System" (FPS) instead of traditional rotors or propellers, acting like "bladeless fans on steroids". These systems use compressed air and the Coanda effect to generate high-speed thrust, promising quieter, more efficient, and faster flight (up to Mach 0.8) for aerial mobility.
OP isn't saying peanuts are a poor source of nutrition. OP is saying a few peanuts are calorically dense and it is easy to consume hundreds of calories through seemingly inconsequential amounts of snacks and drinks.
Calories isn't everything, there is a lot more focus these days on how different foods affect metabolic hormones affecting satiety, blood sugar, etc. On those metrics, fat alone (which account for most of the calories in peanuts) is very satiating and does not trigger a later blood sugar drop (which causes cravings). That's why people on a diet drink 'bulletproof coffee' (coffee with butter in it), because it is extremely filling while not making you hungry later.
In these commercials, it wasn't the technology itself but the ease of access and visualized integration of these technologies into the commoners' everyday lives that was the new idea.
"Our vehicle, called a seaglider, is an all-electric, wing-in-ground-effect craft that operates within a wingspan of the water's surface and couples the speed of an airplane with the operating cost of a boat."
