The bright initial flash of a nuclear weapon is the first indication of a nuclear explosion, traveling faster than the blast wave or sound wave. [6] "A 1-megaton explosion can cause flash blindness at distances as great as 13 miles (21 km) on a clear day, or 53 miles (85 km) on a clear night.
A blast injury is a complex type of physical trauma resulting from direct or indirect exposure to an explosion. [1] Blast injuries occur with the detonation of high-order explosives as well as the deflagration of low order explosives. These injuries are compounded when the explosion occurs in a confined space.
Biophysicists have implicated acoustic impedance, or the ratio of acoustic pressure to particle velocity, as a factor contributing to blast damage in vivo. Wave transitions between tissues with significantly different acoustic impedances, particularly between the external environment and bone, causes focal mechanical damage as a result of wave ...
Individuals with exploding head syndrome hear or experience loud imagined noises as they are falling asleep or are waking up, have a strong, often frightened emotional reaction to the sound, and do not report significant pain; around 10% of people also experience visual disturbances like perceiving visual static, lightning, or flashes of light.
Astronomers are anticipating the appearance of a “new star” triggered by an explosive event that could appear in the night sky anytime between now and September. ‘Once-in-a-lifetime ...
Explosion of unserviceable ammunition and other military items The explosion of the Castle Bravo nuclear bomb. An explosion is a rapid expansion in volume of a given amount of matter associated with an extreme outward release of energy, usually with the generation of high temperatures and release of high-pressure gases. Explosions may also be ...
Astronomers predict that a “new star” will become visible after an explosive event in the Northern Crown constellation, and it could happen anytime. Explosive star event will create once-in-a ...
The explosion should be visible to the unaided eye for several days and just over a week with binoculars before it dims again. Keep an eye out online for reports that the explosion has occurred.
