Mega-impact on Mars: by Nature Video

[agapitoflores001]

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.

[heatflash888]

I wonder if this produced phobos and deimos

[DarwinSilhouette]

its like looking at earth billions of years ago..when it couldnt support life yet...we never know the possibilities..maybe one day it will support life...

[monkeytwineball]

Fascinating!

Does this mean that Mars given billions of years without another catastrophe could stabilize and terraform itself?

[santoro19782]

no...

[monkeytwineball]

Why not? If it had flowing water it was obviously the right temperature.

[santoro19782]

you said it right......it HAD flowing water at some point....

apparently not anymore....

and what about the atmosphere?

it would be necessary an atmosphere like ours and so many other things....

[monkeytwineball]

It has polar ice caps...

If the atmosphere could form once, which it obviously did considering it wasn't either too hot or cold for water, why cant it form again...

[Robfoxman]

@monkeytwineball no, the magnetic field is to weak to sustain a atmosphere

[monkeytwineball]

Venus has no magnetic field, but a very thick, albeit dry atmosphere, magnetic fields lock in hydrogen, which reacts with iron, and mars has lots of iron, and produces water.

So in order for Mars to have had flowing water, it must have at some point had a powerful magnetic field, else the hydrogen would have slipped off into space.

It's my understanding that Earths magnetic field is generated by a molten iron core, Mars has volcanoes... so why doesn't it have a magnetic field?

[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.

[monkeytwineball]

Oh, well that clears that up, thanks.

[A11ex]

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

[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 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

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.

[A11ex]

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

[Treblaine]

@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.

[ajjs02]

Amazing. really excellent. thanks for posting. Fantasic quality as well.
