It was Carl Sagan who did it.

Seriously how was this gif not posted here yet? Dropped the ball GAF.
 
Just saying... Mars kinda looks like Earth in Space Battleship Yamato...


Now I'm not saying it's aliens, but it's probably those damn Gamilasians firing meteors at mars from pluto. The reason why we've never seen it is it happened long before we existed, Mars sent out the Battleship Yamato and it failed, everyone on Mars perished when the atmosphere collapsed and the Gamilasians left their pluto base as there was no more life in our solar system.

We need to get building a space battleship like, right now if we want a chance.
 
There would be something left on Mars, something we could see. There were standing objects made of wood at the Japanese bomb sites. The infrastructure of a typical city runs deep below the earth and would remain in some visible form even if the surface was wiped smooth.

Look at all that's been left on earth despite the passage of time. We scratch the surface and find fossils from billions of year ago. A Martian civilization would leave behind something we could have seen on earth by now. There would be no need to guess or speculate, even if it was a billion years ago.
 
What if Aliens launched the nuke from a far away galaxy aimed towards Earth, and someone turned up drunk to work that day and got the coordinates wrong and hit Mars instead?
LoLLLL!! Missed, bitches. Now we untouchable.
 
ok this is the dumbest shit I've seen in a while

legitimately uninformed assumptions galore

EDIT: mother of fuck it doesn't stop digging
 
I was going to say that nuclear reactions could have occurred naturally, then I reached the end of the article where a real scientist stated so.

It is really interesting that Xenon-129 was found there in rather large quantities, though.
 
The twist:

The ancient Martians were nuclear weapons, having forcefully genetically engineered every single member of their species into sentient radioactive explosives as the ultimate method of maintaining world peace via M.A.D. (mutually-assured destruction) ensured on an immense personal scale, making murder and war wholly undesirable.

The Martians were all biologically immortal because they were inanimate objects, but because they couldn't move due to a lack of a means of locomoting their own body weight, they all suffered lives of eternal hunger and sex pangs; basically, a global pandemic of 'I Have No Mouth and I Must Scream'.

With their entire numerically-stagnant global population immobile, hungry and horny for all of eternity due to their hubris, it was only a matter of time before many individuals contemplated suicide, all the more dangerous because they were nukes.

Those that survived the apocalyptic millions of self-detonations were catapulted to far reaches across the solar system; some never to be heard from again, some landing on ancient Earth by chance.

The Manhattan Project was based off the government's dissection of Martian corpses found from the Roswell Incident. All modern nuclear technology is actually based off of the organs of Martians.

Now, unbeknownst to us, the surviving members of the Martian race hide amongst our armouries on Earth, waiting in silent suffering for the eventual day when we either launch or dismantle them...
 
I am an idiot. I interpreted the thread the title as "the nuclear strike from the end of the Aliens movie eradicated life on Mars"
 
If aliens are smart enough to travel across the galaxy they wouldn't have to use lowly nukes to take out a planet. Nor would any non space-fairing species have any chance of fighting against instantaneous annihilation. Pretty much makes any alien attack movies full of bunk.

1000 years after the importation of gunpowder weaponry to Europe, we still use refined variations of that technology to power the majority of our weapons. A fission-fusion bomb is an elegant and efficient weapon, there is no guarantee that they will ever be totally supplanted as a concept for strategic explosive weaponry. They could be, but we can't just assume that they will. Maybe they will have higher yield versions, delivered through extremely sophisticated mechanisms, but still use a fission base for the initiation of a fusion reaction - fissile materials are cheaper and easier to make than antimatter, that's unlikely to change at any point in the future.

To give a point of comparison, a relativistic kill vehicle requires unbelievable levels of energy to make them work - obviously every joule of energy delivered on impact is a joule of energy that needs to be imparted into it by it's drive. It's also a strategic weapon that requires years of time to launch, assuming that it's being used in the context of interstellar warfare. It's not hard to hit a planet, but it is slow to hit a planet, and you need to be sure that you want to hit it a head of time. It's not going to be effective if you have to spend 11 years sending a scout, then slowly travel back, then fire the weapon which itself takes 6 years to get to your opponent. A scouting group could be equipped with efficient, high yield nuclear weapons to achieve large scale destruction on the spot.
 
Almost bobody is trying to discuss an article about a paper who is going to be peer reviewed, making fun of things we don't understand is surely better.

I'll wait for this theory to be reviewed by the scientific community.

Published by Journal of Cosmology, number #249 on http://scholarlyoa.com/2014/01/02/list-of-predatory-publishers-2014/
Shrug.

There will be no peer review. It was published in a predatory journal. While it's dressed up as one, it's not actually a conventionally intended scientific paper.
 
My theory is humans from the future sent the nuclear bomb to the past of mars to destroy competing lifeform that was going to form in mars.
 
They are us, when you get a second..

This sums up a lot of ideas about Mars in relation to earth. Long story short, Martians were assholes. They could have blown themselves up.

I watched more of this than I should have because I thought "this guy has done some pretty cool stuff in the past".

Then I started wondering why he wasn't talking about video games.

But I kept going because at least he's entertaining.

The problem with that is that we are still limited by our mental ideas of technology. It doesn't have to just be a big bomb, they could potentially use any forms of esoteric weaponry beyond our imagination. Here's just a couple off the top of my head.

Reflective nanomachines. They could form a super thin enormous reflective film that collects sunlight and concentrates on areas of the Earth, vaporizing everything in it's path all while being in orbit on the other side of the solar system. Or even the opposite, surround the Earth cutting off all sunlight.

Grey Goo. Drop a nanomachine "seed" that grows and consumes everything on Earth

Mess with our atmosphere. They'll know waaay before they get here what our atmosphere consists of. They could start some kind of chemical reaction that'll mess up our balanced ecosystem.

Hell, even something as simple as a kinetic bomb traveling close to the speed of light, (or faster!) Whatever form of energy they have that can get them close to the speed of light could be focused on our planet somehow. Again, they wouldn't even need to be anywhere near the Earth.

We would be completely powerless to fight any of these and many more and they would all be doable by any species that has the ability to travel from across the galaxy.

Martians destroy themselves but some survive-->Come to Earth-->We are destroying Earth-->Go back to Mars?

I'm not saying they can't in principle use exotic weaponry, merely that we should not assume that they would abandon the kinds of weapons we have at our own disposal purely for the sake of being exotic. Your premise was that aliens would not use nukes because they're "lowly", therefore the theory presented in the OP is bunk. That's not a good argument, because you're making unjustifiable assumptions about hypothetical weaponry.

A giant mirror to bake the earth sounds like a really overcomplicated way to kill life on Earth. The "easiest" (something we could theoretically do right now) way would be to make minor adjustments to the course of an asteroid to steer it onto a collision course, since you're only making course corrections you don't have to expend huge amounts of fuel (relative to something like an RKV, which would require a disgusting amount of an entire star's energy output to implement). But this is not really important, it's not hard to imagine a circumstance in which a nuclear bombardment is the easiest, cheapest, fastest or most practical solution to something.

Even with the most powerful telescopes, somebody would need to get very close to tell whether or not there was life on a planet. Radio waves or something could tip them off to a civilization in one brief stage of it's life (We've been broadcasting for ~100 years, we may stop broadcasting inside of another 100). If they needed to decide whether it was a potential threat or not, they would need to get even closer still. If scout ships are in orbit around a planet to get samples, to determine the status of a civilization and so on, if the decision to destroy it is made, they can simply unload their payload of nukes and have the whole place leveled inside of 4 hours. I don't know what's "wrong" with this, conceptually. Could an out of control von neumman machine self replicate and eat the whole planet? Maybe, but I don't know why that would be a preferable alternative, it sounds pretty dangerous and not even remotely swift. Maybe they could introduce some subtle mechanism to destroy the civilization, or they could fly off into the outer solar system, steer asteroids into collision courses. Although that might take a while.

What would or would not be appropriate would depend entirely on circumstances and on speculative technology. But it is not appropriate to just be like "well of course they wouldn't use nukes".
