the fuck is this crap

nuclear explosions do not happen 'accidentally', nevermind nuclear explosions that are strong enough to irradiate a planet.

You need extremely precise explosives to get the fuel supercritical.

>The radioactivity also explains why the planet looks red.

>>2845684
you dont need any explosives to get the explosions supercritical all you need is a lot of uranium and a moderator of some sort

>>2845714

>implying ordinary uranium blows up.

>>2845684
not strictly true, you just need critical mass of uranium. Plutonium is the one that needs explosives around it.
Finding a natural deposit of that much pure uranium though, not likely

>>2845742
implying that only processed uranium will blow up

>>2845708
Wtf I thought it was iron oxide dust

>>2845742
Of course it does. I once looked at a uranium the wrong way and then it blew up and raped my cat.

>>2845773
didn't you know, radiation is red

Sounds like a crackpot theory...

>>2845714
>>2845751
You need Uranium 235 to create a nuclear bomb, and it requires sophisticated processing to make it.

It also requires explosives to smash one piece of uranium into another piece of uranium.

This also produces an extremely low-yield bomb. A few tens of kilotons at best. Not even close to what the article is talking about.

>About 180 million decades ago, a planet-shattering still normally happening nuclear reaction might have wiped out every little thing on Mars, sending a shockwave that turned the planet into dry sand.

Worst sentence ever

>>2845756
>implying youre not a retarded inbred faggot.

l2Uranium.

>The Martian surface is covered with a thin layer of radioactive substances which includes uranium, thorium and radioactive potassium — and this pattern radiates from a hot spot [on Mars]

Could have just been a weird asteroid, no (large scale) fission taking place.

Goddamn people still trying to ride the fear wave of Fukushima to fame.

>>2845826
Also bombardment of radiation from the sun with no magnetosphere protection.

>>2845826
That is somewhat more likely.

>>2845816
Uranium 235 is not made it exists in all Uranium sources its just natural uranium has a lower concentration of it also wtf was this
>It also requires explosives to smash one piece of uranium into another piece of uranium
where are you getting your info from nuclear bombs come from fision not fusion.
you clearly dont know what your talking about so gtfo of sci/

>>2845841
Dude, you are not going to get a natural nuclear bomb happening with the uranium 235 that's naturally present in the environment. Stop being a retard.

The REASON it needs processing is because 235 makes up less than one percent of all uranium in existence, and it needs to be something like 90% concentration to even have the possibility of going critical.

>>2845841
This poster confirmed for completely stupid.

Picture related, it's what a uranium bomb looks like.

>>2845861
> and it needs to be something like 90% concentration to even have the possibility of going critical
> to be something like 90% concentration
> 90% concentration
lol do some research its more like 3-5%

>>2845880
It's fission.

>>2845880
the detonator in a nuclear bomb forces a moderator which will usually be a liquid to mix quickly with the uranium allowing for a quick burst of energy
means you get more bang for less uranium doesnt mean its essential for a nuclear explosion

Looks like a rock to me.

Same exact fucking coloration as its environment.

>>2845900
I can't even parse that.

Consider a pile. This is what may, possibly, in an extremely unusual theoretical case occur naturally.
It will not ever explode like a bomb.

>The radioactivity also explains why the planet looks red.

>>2845888
3-5% wouldn't even get hot enough to cook breakfast. Let alone heat a reactor. Let alone explode!

I like this story better, at least it tries to make sense..

anything involving mars is just to far off for me.

Shut the fuck up about fissile materials already
http://en.wikipedia.org/wiki/Critical_mass#Critical_mass_of_a_bare_sphere

>>2845926
I know what a retarded notion

Has nobody consider the possibility that this was an April Fool's that was published a day late?

>>2845939
I just read it, It's mind-boggling.

>>2846059
I wish there were ever respectable examinations of such things.

I mean, that's interesting and suggestive shit right there.

Why do people have such as problem with mars having a natural nuclear explosion? We had a natural nuclear reactor

Can I get a more reliable source?

>>2846103
Not really. Here's the best I can find.

It's like I'm really in 2007 again

>>2846114
>>2846114
It wasn't wikipedia, jackass, and it was a VERY questionable website posting utter bullshit.

>a crater and a poem
>must be ancient nuclear weapon

>>2846096
Because a nuclear reactor, and a nuclear bomb are two fucking different things

>>2845660
>the equivalent of 1 million one-megaton hydrogen bombs
I can't believe they didn't use the new measurement unit: the hiroshima and nagasaki bombs.
I'm in awe and shocked at the same time.

>>2846139
True, nuclear bombs don't need a moderator and are therefore easier to naturally occur

>>2845939
“Lonar is a place of obscurities, especially as the only meteoric crater formed in basaltic terrain. It has remained relatively intact due to low degree of erosion by environmental agents, making it an excellent model for study. However, several strange things happen here:

1. The lake has two distinct regions that never mix — an outer neutral (pH7) and an inner alkaline (pH11) each with its own flora and fauna. You can actually do a litmus paper test here and check this for yourself.

2. There is a perennial stream feeding the lake with water but there seems to be no apparent outlet for the lake’s water. And it is also a big unsolved mystery where the water for the perennial stream comes from, in a relatively dry region like Buldhana. Even in the driest months of May and June, the stream is perpetually flowing. Lonar generates questions and more questions”. Lilyn Kamath

>First off, I doubt the geological validity of her opening statement.
>Secondly, HOW THE FUCK HARD CAN IT BE TO FIND OUT WHERE A GODAMNED STREAM COMES FROM?
>I've done that myself as a bored eight year-old, for god's sake.

>>2846143
Why didn't they just say "1 million megaton bombs"?

>>2846146


That's not how a nuclear explosion works...

>>2846154
Journalists are some of the stupidest people you will ever meet, is why.

>>2846183
They wrote and published this article, so go figure.
Did anyone else try leaving hateful comments that the moderation will never allow?

>>2846143
>1 million one-megaton hydrogen bombs

Speaking of which, my mass is equivalent to 53 one-kilogram triple-ended styrofoam dildos.

guys guys, /x/ here.

We had an alien chime in last week, and Earth used to be populated by an extremely advanced human civilization tens of thousands of years ago, but a global war [with the help of the tower of babylon which was an orbital space station armed with particle cannons] resulted in the melting of the icecaps and massive flooding everywhere, in addition to nuclear strikes around the planet.

An alien race swooped in afterwards and claimed us as slaves. They've placed a veil over the planet that prevents the use of what we would call magic, in order to prevent any possible rebellions.

Apparently some of the old solar power stations might still exist in close solar orbit. We had also colonized parts of the outer system, particularly Iapetus, and we had faster than light capability and were part of galactic politics and trade.

>>2846154
Why not just say one million-megaton bomb?

>>2846200
uh... that's nice?

>>2846200
any chance that thread was saved somewhere?

>>2846200
Of course, there was even a historical documentary about that!

>>2846220
Better question is why do you care?

>>2846220
I recognize what he's talking about, and I did in fact save that thread: http://www.mediafire.com/?579ehbwehrsoqh6

SHOCKING TOP SECRET INFORMATION LEAKED OUT! AMAZING.

>>2846237
Thanks. I thought that was the thread you were talking about. It was a good read.

>>2845785
I don't know why but that made me laugh.

wow. Some posts just disappered right in front of my eyes.
Far out.

>>2846278
aliens did it

>>2846278
If your talking about the youtube link, i'm the one who posted it, and I deleated it too after watching it. Should have watched more than the first two minutes of it before posting the link because it went full retard.

Don't worry, the CIA have not yet discovered the existence of Green Oval:

Are you criticizing my grammar you faggot?

Cause I have Firefox you nigger!!11

>>2846361
oh yeah well I didn't even read your post

>>2846
I don't even know that your post exists. I'm just talking to myself here for the sake of schizophrenia.

>180 million decades ago

MFW

>>2846403
1800 million years ago.
What's wrong with that, besides the consistently idiotic wording?

It's possible for a natural nuclear reactor to exist , both fission and fusion, but not a nuclear bomb like the type America drops on other countries.

>>2846203

Why not just say 1 Teraton bomb.

>>2846416

No one would ever say 180 million decades ago, you'd just say 1.8 billion years ago

>>2846425
Yeah, it's retarded phrasing, but...

>>2846424
Why not just say "We don't know what the fuck we're even saying but it was a big motherfucker."

>>2846432
The scientific term is a doozy.

Lazy fuck linking wiki articles. That I am but natural fission reactions are nothing special:

http://en.wikipedia.org/wiki/Nuclear_fission#Natural_fission_chain-reactors_on_Earth

Uranium/thorium/potassium remnants are not the signature of an ancient nuclear blast. Deep excavation, maybe.

>a large red spot that would seem like a radiating debris pattern … on the opposite side with the planet there exists a different red spot.

Or a small object at extreme velocity punched straight through. There would be ample secondary radiation from such an impact and it would have thrown up materials from the interior.

>The radioactivity also explains why the planet looks red.

>>2845939
>carbon-dating involves measuring the amount of radiation left

Could of sworn it was red because of Iron Oxide
