Project A119: The US planned a nuclear explosion on the Moon


The aim of the top-secret project A119 was to detonate a nuclear bomb on the Moon. The flash of explosive light would have been faintly visible to people on Earth with their naked eye; an US show of force after the Soviet Union took an early lead in the Space Race

 



In vacuum, objects fall at the same speed

In vacuum, objects fall at the same speed


The acceleration of the object equals the gravitational acceleration in vacuum. The mass, size, and shape of the object are not a factor in describing the motion of the object. So all objects, regardless of size or shape or weight, free fall with the same acceleration. Thus in a vacuum, a beach ball falls at the same rate as an airliner!

A gauntlet to manipulate objects using accoustic levitation


Accoustic levitation can trap particles in air or water and the gauntlet is a project aiming to enable humans to capture, move, and combine them

Extreme lightning produces antimatter and gamma rays


Dark Lightning is a very strong, invisible by-product of thunderstorms in the Earth’s atmosphere. Instead of producing light and heat, like regular lightning does, dark lightning releases bursts of gamma radiation from positrons within thunderclouds

This video shows how the silencer of a gun works


The silencer allows for the pressurized gas behind the­ bullet to expand into a bigger space. The pressure of the hot gas therefore falls significantly, softening the sound
