Can gravity stop an explosion?

In absence of gravity, the explosion will be just like it would be on earth (in gravity) unless we are talking about No gravity, and “vacuum conditions.” In absence of only gravity, debris and shrapnels from the explosion will travel much longer distance but eventually come to halt because of the air resistance.

Is an explosion in space possible?

In space no one can hear you explode… Many astronomical objects such as novae, supernovae and black hole mergers are known to catastrophically ‘explode’. But as long as the explosion doesn’t require oxygen, then it will work in much the same way in space as on Earth.

Does gravity affect explosions?

Supernovae occur when a massive star runs out of nuclear fuel, its gravity causing it to collapse and explode. …

How would an explosion work in space?

An explosion in space would realistically look like a brief spherical burst of light moving outwards, as well as a discharge of energy and material from the exploding object (energy and light can both travel in a vacuum). It would take a moment for the pressure to rebalance from space and for the fuel to be burned up.

What if gravity turned off for 1 second?

When gravity disappears for 1 second the outwards force balanced by the gravity would be released causing a massive explosion. In other star systems with more immense stars and natural phenomena such as pulsars and and especially black holes the explosions and expansions would be greater.

Can a candle burn in zero gravity?

A candle can burn in zero gravity, but the flame is quite a bit different. Fire behaves differently in space and microgravity than on Earth.

How would fire burn in space?

Fire is a different beast in space than it is on the ground. When flames burn on Earth, heated gases rise from the fire, drawing oxygen in and pushing combustion products out. In microgravity, hot gases don’t rise. Space flames can also burn at a lower temperature and with less oxygen than fires on Earth.

What happens to a fire in zero gravity?

Combustion experiments conducted in zero gravity yield surprising results. The flame persists because of the diffusion of oxygen, with random oxygen molecules drifting into the fire. Absent the upward flow of hot air, fires in microgravity are dome-shaped or spherical—and sluggish, thanks to meager oxygen flow.

What happens if there is no gravity in space?

But odd things happen in space, where gravity loses its grip on solids, liquids and gases. Without gravity, hot air expands but doesn’t move upward. The flame persists because of the diffusion of oxygen, with random oxygen molecules drifting into the fire.

How does a zero-g fire a bullet?

Instead, both semi-automatic and automatic guns rely on springs (not gravity) to bring the next bullet into the chamber, before a small explosion within the gun fires the bullet. However, as in the film, a zero-g gunman should exercise some caution, as firing a bullet would also send him or her flying in the opposite direction.

How can we simulate weightlessness without escaping the gravitational pull?

So exactly how can we simulate weightlessness without escaping the gravitational pull of the Earth? The simplest answer is that we observe an object in free fall. Free fall is when an object falls solely under the influence of gravity. Because of air resistance, an object can’t truly be in a free fall without being in a vacuum.
