Can anyone write a stub here? What is an explosion?
I've been hopping from one article to another this morning trying to track down the difference between propellants and explosives. Maybe I'm wrong on the previous couple edits. —Preceding unsigned comment added by 71.63.88.111 ( talk) 07:09, 6 September 2008 (UTC)
We need a Definition here of the difference: By a Chemist's, an Expert's' definition: An explosive detonates at a velocity of 3,000 feet per second or more. It is usually one substance, it Detoates at an exponential rate. It usualy requires a detonator; most won't simply explode with a "fuse". A propellant; black powder, smokeless gunpowder, flash powder, etc, are often two or more separate substances that deflagrate, that is, burn quickly. They are designed to go off when lit. Their velocity is usually subsonic, about 600-900 fps. A test: If gunpowder is laid out on some concrete and is set off, it goes Poof, impressive, but, the concrete is still there. The explosive force takes the path of least resistance; it goes upward. If some high explosive, say, RDX, is detonated on a slab of concrete, it will explode at 25,000 feet per second. The supersonic shock wave reflects the explosive force downwards, and there is a hole blown in the concrete. 70.162.46.94 ( talk) 14:05, 25 August 2011 (UTC)
this term is used formally, and sometimes measurably, as a nonlinear increase in sets or populations-- 74.236.193.55 02:08, 17 November 2006 (UTC)
It is incorrect to call the Big Bang an explosion. While often portrayed as such in popular accounts, this is deeply misleading, since there was nothing that exploded, nor was there anything to explode into; the Big Bang is simply the initial singularity of spacetime and/or the hot initial state of the universe, depending on your terminology. While associated with heat and an expansion, it is not an explosion in the conventional sense, and hence should be removed from the list of explosions. 142.3.164.195 23:55, 5 June 2006 (UTC)
The Big Bang is not an explosion it is an expansion because it has not/will not stop.
I'm no expert, but seems there should at least be mention of the explosive potential of fine dust when diffused in air--in the U.S. west, grain elevator explosions are an all-too-common phenomenon.

Yes, and the fire-damp--explosions of fine coal particles in air. Both can be deadly.

The Texas City Disaster of April 16, 1947 ... found elsewhere in Wikipedia ... surely is one of the major explosions of a chemical nature.
shoemaker-levy 9 shouldn't be here, because it didn't explode. it was pulled apart by jupiters gravity and then collided with the upper atmosphere. It doesn't qualify as an explosion, so i'm removing it. Dallas 09:56, 1 August 2006 (UTC)
How about a section for really big non-nuclear, deliberate explosions like Minor Scale? That's not the largest ever by a long way. The US military once stacked up enough TNT in the Nevada desert to equal the power of the Fat Man or Little Boy bomb. It was either in the 1960's or early 1970's. I saw it on a documentary on TV a few years ago. Many men were examining a dormant volcanoe when it exploded and killed them. This shows that dormant volcanoes can still be active, so take precation. They found a body with many bullet wound type things but they had been rocks that punctured his skin and went into his heart. One guy was missing his head. Nasty.
I'm no expert, but isn't an explosion a combustion that has accelerated into supersonic velocity? So something has to burn with a certain speed expressed in meters per second to be counted as an explosion? Then, there's no such thing as a "Gasoline explosion" (image text). Burning of gasoline should then, strictly speaking, not be counted as an explosion. -- 85.165.66.228 ( talk) 07:55, 13 September 2008 (UTC)
Gasoline burns in an auto engine. If it explodes, it's called a "knock".

I was hoping to find information on the sound of explosions on the page, but... no. Aside from what different real explosions sound like, a mention of how hollywood explosions usually don't sound real would probably be useful information.
There's probably a lot of attributes of explosions that aren't as sexy as the different materials that can explode but that should be in the article. —Preceding unsigned comment added by 91.153.238.155 ( talk) 16:09, 5 May 2009 (UTC)
Perhaps a small section can be added displaying how much damage several explosions (described in Ktons or released energy) can cause. E.g. how much released energy/ktons of explosives will damage a certain size of area (in m²); how much will incapacitate or even kill a man, how much will damage a house, a larger building, ... —Preceding unsigned comment added by 81.245.85.122 ( talk) 12:12, 25 May 2009 (UTC)

From the intro to the article: "Subsonic shock waves are created by low explosives through the slower burning process known as deflagration."
This makes no sense. A shock wave, by its very nature, must travel at a supersonic speed. If it's subsonic then the temperature/density/pressure would be able to propagate through the medium faster than the shock, and the shock wouldn't exist at all. —Preceding unsigned comment added by 76.181.65.49 ( talk) 02:49, 6 June 2010 (UTC)
No. Shock waves can travel as slow or fast as they want.The shock waves travelling thru the deflagration of the low explosive propellant travel In Air at at usually a subsonic velocity, by definition. They don't "speed up", they are the propagation velocity of the substance.
Now, if you are talking shock waves thru ground, or water,they often travel at 4-5x sound, as sound waves go faster thru denser mediums. 70.162.46.94 ( talk) 14:12, 25 August 2011 (UTC)
I thought this might be an interesting video for this topic. I don't know if this kind of video is appropriate for wikipedia, so I post it here. The video shows all the mentioned elements of the explosion in the last part of the other youtube movie. It also shows the debris of the gas tank flying into the air as a result of the explosion. Do you think it's worth to link this video too? —Preceding unsigned comment added by 84.72.76.249 ( talk) 00:59, 4 May 2011 (UTC)

What is this supposed to mean: Black smoke from an explosion rising after a bomb detonation inside the outside Nahr al-Bared, Lebanon.? Inside the outside? 7&6=thirteen ( ☎) 22:52, 28 October 2015 (UTC)
Accidental lab and factory explosions are frequently documented in the news. Poor ventilation, gas vapors, and dust is often the cause. — Preceding unsigned comment added by CharlesMJames ( talk • contribs) 16:38, 1 August 2017 (UTC)
Both this page and the Wiktionary entry for Explode suggest that the word began to be used (or at least is earliest recorded being used) in its current meaning, "to burst with destructive force," in 1882. Neither page cites a source. What happened in 1882? Where was it used? If it was written down somewhere, where? Can anyone track down where on earth this unusually exact year came from? 2600:1700:DAE0:EB40:FC47:6A33:1607:ACD6 ( talk) 09:54, 4 February 2019 (UTC)
