Space Shuttle Destroyed Video on YouTube

[TFH]

Hi people,

Im the guy who created the Space Shuttle Destroyed 2009 video on YouTube. Not that I want to see it for real, it was just a vision I had in my head. So please don't hate me

Also, thank you to the people on this forum that have taken the time to think about the cause behind the video. It helps me reading stuff like that.

Here are a few strange questions:

I was just after some advice regarding the physics of explosions in space. What would happen?, would we see, flames or just fast expanding gas clouds?. Also.. If the Earth was to split in two, say from a massive fault in the tectonic plates, what would be the view of the Earth from the moon.... would we see the lava core expaning out and our atmosphere being sucked into space?

It's just that Im working on some new videos for my YouTube channel.

As you have read, Im a strange thinking sort of guy....but some of us have to be strange, to make the weirdos think their normal.

regards,
TFH.

Plasma. Which means all and nothing. Plasma is influenced by magnetic fields and these are even caused by the flow of plasma itself.

A normal explosion in space would not be much different to what you have on Earth, but you would have no atmosphere or gravity influencing it usually. You would get no convection inside the explosion - no mushroom clouds, no slow flames. Take photos of the first microseconds of a nuclear explosion they should give you a good idea. But instead of turning into a mushroom cloud, the explosion would just fade out.

The high altitude nuclear explosions are the best we know about explosions in space, but EMP effect of them also caused some differences to chemical explosions in the long run - the large artificial and menacing auroras are not part of non-nuclear explosions.

Also.. If the Earth was to split in two, say from a massive fault in the tectonic plates, what would be the view of the Earth from the moon.... would we see the lava core expaning out and our atmosphere being sucked into space?

No, not at all. Earth is held together only by gravity. Even the higher surface pressure on Earth is caused only by gravity - if space could suck anything away from Earth or from inside Earth, it would already do so with the atmosphere. But in reality, each molecule in the upper levels of the atmosphere follows it's own orbit until it is blown away by solar wind or collides with another molecule.

You would need to create a massive overpressure inside Earth to make it explode completely. Really massive - you would not only just have to counter the internal pressure by gravity, but also keep this pressure up during the expansion, so Earth does not collapse back into (roughly) it's old shape. The more you reduce the density of Earth, the lower should be the pressure needed to expand further.

A planet can't just start to fly apart, getting something to split a planet in two would be hard.
More likely is a central explosion ripping the thing into pretty much a fluid-like incadescent cloud, which will re-form into a glowing sphere with shells and rings of orbiting debris, or continue to expand into a debris belt around the Sun, cooling down slowly.

Splitting it in two will need something quite atypical, with results looking like depending on what exactly was used.

If you spread the bombs along a plane going thru the planet, it might give you a split-in-two effect. Then, as i understand it - the two parts will move away, crust expending outwards and peeling off. Initially pancacked, they will re-shape into roughly spherical shapes, mostly molten or covered with internal magma.
A significant ring of debris along the split line will probably fly off in all directions.
If the boom was not strong enough, the parts will fall together, eventually settling into a molten ball of rock with shells and rings of orbiting debris. The Moon will remain undisturbed, unless hit by some large pieces.
If the boom was strong enough, there will be three planets and a debris belt in the Earth's neighbourhood for some while, with high likehood of new large collisions.

For a central explosion, the air will just fly everywhere along with the rest of the cloud. There will be no big jagged chunks, more like pulverised magma and rock. The pulverised fluid will likely eventually form some large (as in ~100km tops) blobs, lots of smaller blobs, and the rest will spread out around the solar system.

For split-in-two explosion, the air will partially cling to the resulting planetoids, with some forced completely away.

Main point is:
A planet might look solid, but it's basically a fluid, especially under forces, strong enough to rip it apart.

It's worth it, whatever people say.

It is a great video!

One thing I would change however, is the rate of the smaller debris. The smaller debris appears to move at a different rate to the larger debris. In reality, it would move at the same rate.

Depends on the fragmentation model. usually you can expect to have a Gaussian velocity AND fragment size distribution.

WOW!! what detailed replies. Thank you so much. It all helps.
