Lightning as we know it in air cannot happen in vacuum because lightening depends crucially on the generation of positive ions and negative electrons by ionization of molecules of the air in high electric fields (and eventually high temperatures) and the ensuing impact ionization typical for a gas discharge.
Electrons can jump from one surface to another in vacuum, but they require a larger voltage to do so than if there were air in between the surfaces. If you define this to be lightning, rather than the resulting breakdown of air molecules that normally occurs, then yes lightning can occur in vacuum.
This is what our research found. because of this light does not require a medium for propagation. They can travel through a vacuum. Was this answer helpful?, and thank you. Your Feedback will Help us Serve you better.
Lightning can travel through any metal wires or bars in concrete walls or flooring. Even though your home is a safe shelter during a lightning storm, you may still be at risk.
Could Lightning come from space?
Not in ‘Deep Space’ as it’s commonly viewed, which is basically a whole lot of nothing. Lightning is effectively a large discharge of static electricity. With nothing around, there’s nothing to build up a charge. Which is by no means to suggest Earth is the only place with large static discharges.
Is it possible to get lightning in space?
Yes, lightning occurs in space . It occurs in the clouds of planets and in molecular clouds in space as well from other phenomena in space. These colorful flashes are called blue jets and they can stretch 30 miles into the stratosphere.
Another common query is “Does Lightning take up space?”.
One source argued that the Empire State Building was once used as a lightning laboratory because it is hit nearly 25 times per year, and has been known to have been hit up to a dozen times during a single storm. Myth #2 – Lightning only strikes the tallest objects. Fact: Lightning is indiscriminate and it can find you anywhere. Lightning may hit the ground instead.
Does Lightning come from Outer Space?
This idea is not new: More than 20 years ago, physicist Alex Gurevich at the Russian Academy of Sciences in Moscow suggested lightning might be initiated by cosmic rays from outer space. These particles strike Earth with gargantuan amounts of energy surpassing anything the most powerful atom smashers on the planet are capable of.
Electrons, flowing as the lightning propagates, are free electrons, not bound to nuclei, and if they accelerate, they can emit visible light. Thus lightning would be possible in vacuum, and it could be visible too. Is lightning an example of energy emision from accelerated charge? The sort answer is no.
Is it safe to be inside during a lightning storm?
Even though your home is a safe shelter during a lightning storm, you may still be at risk. About one-third of lightning-strike injuries occur indoors. Here are some tips to keep safe and reduce your risk of being struck by lightning while indoors., and avoid water.
Basically, lightning is visible because of the heat that is generated in the molecules of air, and the flow of the current is possible only because air atoms are ionized by the electric field, and the air molecules, in a plasma form, have atoms in excited state, and when these relax, they emit visible light.
Can a grenade explode in a vacuum?
First, in the instance of a grenade, frag or High explosive, it would and could theoretically explode in a vacuum, however, it most definitely would not look like the movies or make any sound in space. Since it needs no outside sources of oxygen to explode, it would start of like a normal earthly explosive reaction.
