Question: What Happens If There Is An Explosion In Space?

Can you pull the pin of a grenade and put it back?

Yes, a grenade’s safety pin can be put back as long as the strike lever hasn’t been released.

A grenade is actually activated by the strike lever (also known as “spoon”).

The strike lever is held in place by the safety pin, and once released, it is held in place by the user until thrown..

Could the Earth survive without the moon?

Without the moon, a day on earth would only last six to twelve hours. There could be more than a thousand days in one year! That’s because the Earth’s rotation slows down over time thanks to the gravitational force — or pull of the moon — and without it, days would go by in a blink.

What happens if a nuke goes off in the ocean?

Unless it breaks the water surface while still a hot gas bubble, an underwater nuclear explosion leaves no trace at the surface but hot, radioactive water rising from below. … During such an explosion, the hot gas bubble quickly collapses because: The water pressure is enormous below 2,000 feet.

Does your head really explode in space?

Humans don’t explode in space. Even though outer space represents a lack of air pressure, which usually counters the internal pressure in our bodies, our tissue is strong enough to handle the imbalance. … Humans exposed to the vacuum of space don’t explode.

Are explosions in space silent?

It’s pretty much the same for a supernova. The gases from a supernova explosion expand rapidly, and the density will drop off fast. … So we won’t ever hear a supernova explosion on Earth, for example. It’s a little sad, but space really is silent.

Who owns the moon?

The Outer Space Treaty means therefore that – no matter whose national flags are planted on the lunar surface – no nation can ‘own’ the Moon. As of 2019, 109 nations are bound by the Treaty, and another 23 have signed the agreement but have yet to be officially recognised.

Can cockroaches really survive a nuclear explosion?

No, cockroaches cannot survive a nuclear explosion. While they may be able to withstand extreme radiation exposure due to the simple design of their bodies and slower cell cycles, they certainly cannot tolerate the high amount of heat energy produced immediately following the explosion.

Can you nuke a black hole?

For a black hole, any matter entering the event horizon is added to the mass. … Detonate a nuclear bomb inside the event horizon, and you only make the black hole more massive. Fire your forward phasers at the black hole, and that’ll still make it even more massive.

Can you hear yourself talk in space?

So, Alien has it right; while it’s not strictly true that sound waves can’t travel through space, it is true that humans would not be able to hear those sounds. Scream all you want, no one is hear you. … Among the things you could hear in space are: “¢ Anyone talking to you via radio.

Can you have an explosion 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. … Nuclear explosions can of course occur in space, too. However, in space, there is no atmosphere to transmit sound from the explosion to the observer, so it would appear to be silent.

Can an astronaut hear an explosion in space Why or why not?

It would be the loudest thing imaginable.” Despite the violent nature of the Sun’s constant explosions, Hadfield noted that even astronauts in space couldn’t hear them simply due to the vast emptiness and vacuum of space. In other words, the sound of the explosions produced by the Sun can’t travel across space.

How deep does a bunker have to be to survive a nuke?

3 feetAs long as the shelter is buried at least 3 feet underground, it will protect you from the radiation.

Have we detonated a nuke in space?

On 9 July 1962, the United States conducted the ‘Starfish Prime’ nuclear test, one of a series of five aimed at testing the effects of nuclear weapons in high altitudes / lower outer space. The explosion took place 400 kilometres above the Johnston Atoll in the Northern Pacific Ocean.

Can you survive a nuke underwater?

While the radiation from the initial detonation is setting everything nearby on fire, the surface of the water will harmlessly evaporate. Since the boiling point of water isn’t very high and the flash doesn’t last very long, the whole body of water will stay cool, even if it’s only a swimming pool.

Can you survive a nuclear blast in a fridge?

GEORGE LUCAS IS WRONG: You Can’t Survive A Nuclear Bomb By Hiding In A Fridge. … “The odds of surviving that refrigerator — from a lot of scientists — are about 50-50,” Lucas said. But science has spoken, and it says something a little different.

Do missiles work in space?

Missile defence does not station weapons in space, but is designed to intercept incoming warheads at a very high altitude, which requires the interceptor to travel into space to achieve the intercept.

How far away from a nuclear bomb is safe?

six feetThis will help provide protection from the blast, heat, and radiation of the detonation. When you have reached a safe place, try to maintain a distance of at least six feet between yourself and people who are not part of your household.

What would happen if a nuke hit the sun?

Nothing! Since our nukes are insignificant against Sun’s energy. Although we would be providing more fuel since Sun is a giagantic fusion reactor. Our nukes will provide hydrogen if its a fusion bomb or uranium if its a fission bomb which our Sun would consume in fraction of milliseconds.

Why we Cannot talk in space?

Because there is nothing out in space (like an atmosphere), the sound waves from one astronaut’s whistling can’t travel over to the other astronaut’s ears. That’s why the astronauts use radios to communicate—even if they’re floating in space right next to each other!

What does space smell like?

As it turns out, space actually does have a distinct odor. … Astronauts returning from space claim that their suits smell, in a word, burnt. The lingering scent of space is “acrid” and “metallic,” reminding the astronauts of charred meat or welding fumes.

Can you fire a gun in space?

Fires can’t burn in the oxygen-free vacuum of space, but guns can shoot. Modern ammunition contains its own oxidizer, a chemical that will trigger the explosion of gunpowder, and thus the firing of a bullet, wherever you are in the universe. No atmospheric oxygen required.

Can I hear sound in space?

No, you cannot hear any sounds in near-empty regions of space. Sound travels through the vibration of atoms and molecules in a medium (such as air or water). In space, where there is no air, sound has no way to travel.

Would an explosion in space have a Shockwave?

A ‘shock wave’ is the disturbance of material that’s created when a wave moves through a medium at greater than the local speed of sound. Provided there is a ‘medium’ of sufficient density through which a shock wave can travel, there is no reason why shock waves can’t form in space.

What if we nuke the moon?

The short answer is this: it wouldn’t. You’re gonna need a bigger bomb… Roughly 10 trillion megatons of TNT bigger. An explosion that size would likely push the Moon out of Earth’s orbit, exposing us to meteors, affecting our tides, eventually killing all marine life, while catastrophically affecting our seasons…

Would we die if the moon exploded?

It is pretty obvious: Everyone Dies. First, the explosion of the moon will produce an enormous amount of debris. A significant amount of them will rain on Earth at high speeds and the impacs will be tremendous. Each impact will cause shock waves that can wipe out life in millions.

Does an explosion create a vacuum?

Blast wind: At the explosion site, a vacuum is created by the rapid outward movement of the blast. This vacuum will almost immediately refill itself with the surrounding atmosphere. This creates a very strong pull on any nearby person or structural surface after the initial push effect of the blast has been delivered.

Can you nuke sun?

Not much. The Sun is mindbogglingly vast. Even our biggest nuclear bombs don’t fuse more than 1 ton of hydrogen. Compare that with the Sun’s 620 million tons burned per second: the nuke would add 10−9 to the Sun’s output.

Who nuked the moon?

Project A119, also known as A Study of Lunar Research Flights, was a top-secret plan developed in 1958 by the United States Air Force. The aim of the project was to detonate a nuclear bomb on the Moon, which would help in answering some of the mysteries in planetary astronomy and astrogeology.

What happens if a bomb explodes in space?

In the vacuum of space, the lack of air means the principal destructive effects come not from the blast, but instead from the particles and radiation pouring out of the bomb, which dump their energy as heat on striking the target.

Can a grenade explode in space?

Yes, it would explode. Most hand grenades are nowadays triggered chemically, electrically or contain a fuze enclosed within the assembly, so they don’t require atmospheric oxygen to ignite, are watertight and otherwise more reliably go off at a preset time since activation.
