dinasaurfarts suck (1 месяц назад)
here's another theory. So basically the negatives (electrons) in the cloud repel the negatives in the top layer of soil and then because it is just protons left in the topsoil the electrons in the clouds attract to the protons in the topsoil to make it neutral. And the lightning you see is just electrons transferring from the negative cloud to the positive ground. But then again they are both just theories.
dinasaurfarts suck (1 месяц назад)
but the theories about how the positives and negatives separating is evident in this theory too

I have witnessed a ball of light floating in my room and I dont want to say it is a spirit. So I came up with other ideas as to what it is,hence I'm at this video trying to see what ball lightning would look like if some one captured it but sad to say no footage. I dont think that the ball of light was really lightning in my house so back to the idea of it being a spirit. I wish somebody can help me with what I have seen.

When my mom was little and lived in South Carolina there was this pretty sizable kind of ball of electricity that was recurrent and would usually pop up during storms, it sometimes would move around the house but would usually stay in the kitchen, sort of jumping off of appliances and other metal stuff, it would last for quite a while too, sometimes even hours, does anybody know what the heck that was?

So its like when you apply to much voltage to a capacitor and it explodes
phoenix21studios (1 год назад)
so the lightning is pure electrons? or .... air molecules getting the electrons transferred?

at 0:45 wouldnt the heavy positive ions sink to the bottom of the cloud making it more positive charged while electrons that rise to the top area of tge cloud will make the top area of the cloud negative charged
Damien Thobe (1 год назад)
is lightning AC, DC, or it's own special thing?
phoenix21studios (1 год назад)
DC because its a linear transfer from one molecule to the other.

You guys could easily do these videos 10 minutes plus, there is so much more information to be provided on lightning let alone footage you could show, under 4 minutes is silly bearing in mind the intellect that goes into these, step up your game please.

Thanks for this. I'm still pretty sure I saw a ball of lighting in my room once. It came from the window and floated to the light switch right above my head. As it touched the switch it made a pop! This was during an intense thunderstorm, which woke me up as the lightning zapped. For years I thought I was just dreaming this... This is the first video that gives a credible explanation. Other explanations were just spiritual hogwash! I feel a little sane again about this.

An early capacitor was made using glass, right? Maybe the soil/sand particles in the air are acting like a capacitor, to slow build-up and/or slow-down, the electrical charge. Has anyone tried bringing a tesla coil to the desert, powering it up, and aiming an industrial fan at the ground near-by, to kick up some dust? Or just throw some dirt at a tesla coil… Field trips are more fun though.

Jupiter has Lightning that is even stronger and hotter than anything you could ever see on our planet. That lightning could only be possible on our planet in a Hollywood made Film.

Not bad, but - Like most of your efforts - this really should have been 10 minutes long. That would be enough time to start to explain the 'WHYs,' rather than just spouting semi-random factoids on such a complex subject.

About a week ago, when my family and I were coming home from a restaurant, a lightning bolt hit one of my neighbor's yards. Thing is, it stayed there for about 2-3 seconds before disappearing, and then the about a second or two later, the thunder came. what exactly WAS that?

Ball Lightning was researched by Russian scientists decades ago, who concluded that it formed by lightning strikes on trees—the vaporized carbon, nitrogen, and oxygen, formed nanoparticle-batteries which while individually weak a fraction of a volt each would span their short particle size and arc over... and in total amounted to quadrillions of volts...

How can an electric charge move from positive to negative since electrons are negatively charged? Shouldn't electrons from the negatively charged cloud flow down to the positively charged ground since a positive charge is a lack of electrons? How can a lack of electrons move?

I was in hospital last year and i was sitting at the window at night , watching the lightningstorm. I could see the whole city from above and it was really beautiful and all of a sudden lots of lightning strikes at the same time but all of them where orange. The whole skyline in a bright orange light ... one of the most beautiful things ive ever seen :) It also made my time in hospital a lot more enjoyable :DD

What's the statistics of lightening safety measures and are they worth it? From installing lightening rods (thank you Ben Franklin) to keeping away from plumbing and skipping a shower because there's a lighting storm outside, to avoiding standing under trees in a downpour even though you'd get drenched, etc.

:D I did one of my final year uni projects on ball lightning. The other popular theory you didn't mention, first coined by Kapitza involves the creation of meta stable balls of plasma contained between nodes in the electric field. The main reason it's so poorly understood currently is because of how rare it is. This leads to most reports being non scientific eye witness accounts. Even with advanced statistical handling of observer errors no one theory is able to explain all forms of ball lightning: Some has been said to move through walls and glass (not consistent with and theory that relies upon particles) Some are said to have created explosions or evaporated large amounts of water which require more energy than anyone can work out how to self contain in plasma or to explain with the photon model. Basically either there are multiple different phenomenon that we label as ball lightning or we have to discount some accounts as people being mistaken.

I actually had some ball lightning float through one of the windows in my living room about 2 years ago. It was a beautiful little blue, sparkling ball about the size of a tennis ball, which aimlessly floated around the room for about 30 seconds before disappearing into thin air. I was mesmerized by it, but, if I had known what I know now about ball lightning then, I probably would've been terrified of it. Ball lightning has been known to start fires, short out electrical systems, and strike people, as well as animals.

When my mom was a girl, ball lightning came into the house on the phone line. It stayed in the room for several seconds. That was at a time when all phone lines were above ground. I read an article in Scientific American a long time ago that speculated that ball lightning is a sphere of layers of positive and negative charges (like an onion). I don't remember what they said might keep the charges separated (photon emission?).

I have heard anecdotal stories that I think are reliable of lightning strikes on a fence line causing ball lighting to travel down the fence. I've seen some strange things, but not that.

So you show us 2 videos/pictures of things that last fractions of a second but don't show us ball lightning that lasts 20 seconds?!? That makes so much sense.
