Are explosions possible in space?
Scientists have detected evidence of a colossal explosion in space – five times bigger than anything observed before. The huge release of energy is thought to have emanated from a supermassive black hole some 390 million light years from Earth.
Can ships explode in space?
Yes, provided there is an oxidizer. A spaceship with liquid hydrogen and liquid oxygen will blow up quite well in the vacuum of space. Chemical explosives will also explode in space since they function by breaking weakly bonded chemical components; no oxygen is necessary.
Will jumping on a grenade work?
Yes. Grenades aren’t that powerful. And the explosive force they generate is largely to break the grenade shell up into fragments/shrapnel, which actually cause injury. Jumping on a grenade is near certain death, but also pretty certain to prevent injury (certainly serious injury) to others nearby.
Did soldiers actually jump on grenades?
John Andrew Barnes III was posthumously awarded the Medal of Honor when he jumped on a grenade to save the lives of wounded comrades in the Vietnam War. Olive III was a United States Army soldier and a recipient of the Medal of Honor for his actions in the Vietnam War on October 22, 1965.
What’s the blast radius of a grenade?
Steel fragments (not to be confused with shrapnel) are provided by the grenade body and produce an injury radius of 15 metres (49 ft), with a fatality radius of 5 metres (16 ft), though some fragments can disperse as far out as 250 metres (820 ft).
Can a military helmet stop a grenade?
No, but in the opinion of other infantry veterans, Dunham did the right thing. Anyone who covers a grenade with their kevlar is going to be severely wounded. And, chances are, Dunham would probably have been killed by the grenade regardless due to his proximity.
What do Navy Seals yell when they throw a grenade?
The grenade is a fragmentation grenade, because when it blows up it throws fragments through the air, hence the term “FRAG OUT.” This phrase is yelled loud for all others in the unit to hear.
Can a grenade kill a bear?
Grenade shoved down its throat. Occupies its mouth so that the rest of you is not subject to a bite, explosion actually kills the bear and it will not come after you again.
Will shooting a gun scare off a bear?
For larger animals like bears, a handgun with caliber under 10mm is unlikely to save you and even 10mm is iffy. You’re better off with bear spray. The vast majority of the time, there’s no need even for a warning shot, much less one intended to kill.
Can a chainsaw kill a bear?
A chainsaw would take 10 seconds to saw through a bear’s paw. You have to apply pressure for some time to cut anything. Plus they aren’t great at cutting flesh. The bear could kill a human with one good swipe.
