Mega-impact on Mars: by Nature Video

Scientists have identified what could be the largest impact structure in the Solar System, created on Mars at about the same time as the Moon-forming impact on Earth. Watch them discuss their results here. Three papers in Nature help to explain why one hemisphere of Mars is lower and has a thinner crust than the other.

Soon will expand our domain to Mars by the time earth population exceeds land area.

Maria Zuber and Ellen DeGeneres have like the SAME EXACT voice wtf.

@A11ex Awww, I'm crushed, you had shared such pearls of wisdom and knowledge already (sarc).

You were acting like an asshole. And like a typical asshole, you get pissy about being called one. My god, are you this much of a passive-aggressive outside of youtube commenting?

You started this bullshit.

[A11ex]

@Treblaine I was going to ENLIGHTEN you but since you are the "asshole-prick" calling type I won't.

[Treblaine]

@A11ex

What are you going on about? You say you are a geologist? Then why are you talking like an asshole?

If you have other information please, ENLIGHTEN us. Don't be a stuck up prick claiming you know contrary but not actually committing to saying anything.

I don't have to cite references for every little thing I suggest. I've only got 500 characters and can't post any links. So what's your problem? I'm going by what I remember from a documentary, name of which I have forgotten.

@Treblaine Suggesting a geologist to "do further research" is one stupid idea. XD First, you still haven't defined even one of the terms you're using. Second, you haven't presented any evidence for your claim. Third, when pressed you back off suggesting something, you haven't done yourself in the first place. Fail. Uberfail if I may add.

[Treblaine]

@A11ex For example, THE Pacific ocean, on earth.

Evidence: Olympic Mons itself.

I'm not conducting a seminar, I suggest if you are interested in this you do further research yourself, go to your local library or use the internet.

[A11ex]

@Treblaine Define "oceans". Define "significant amount". Define "a lot of evidence".

[monkeytwineball]

Oh, well that clears that up, thanks.

[Treblaine]

@monkeytwineball No, Mars HAD volcanoes.

Those volcanoes on Mars are all long extinct, nothing but mountains now.

Though it is telling that the largest known mountain in the known Solar System is on Mars (Olympus Mons), an one thing that prevents mountains getting so big is erosion, usually through water. There is a lot of evidence that Mars never had any significant amount of water, certainly not entire oceans.
