Could Mars Be Our "Planet B?" | Naked Science | Spark 

exactly.. that was the reason I got premium.. the ads would wake me up if I fell asleep while watching something.

💯

I totally empathize.

Yes there Ads do appear Twice as Loud as the Video. I am suprised RU-vid did not Detect it during the Copy Right Scan.

According to the credits, this was made 2007/2008.

no u

THE WORST most inhospitable places on Earth, are FAR better habitats than any planet humans can land on (that is ONE planet, Mars).

The planet will be fine.. It's us humans who won't be fine.. The planet will revitalize itself once we are all gone.. just like after the Ice Age

Methane gas will be the fuel water all so

@@stanleydavidson6543 - The economy can not be based on that. There will never be a self supporting villages, towns or cities on Mars for various reasons, like economy, insurance and last but not least, the 38 % gravity of earth.

Lots of metal and resources

None of that when the new world was discovered

@@stanleydavidson6543 Do what? Uh, there was air, arable land, wood was the chief source of fuel but eventually coal was found. The New World was nothing but resources. Mars will be MUCH MUCH more difficult.

whats the alternative?

Exactly what I came to say! If we can make another planet habitable, we can keep Earth habitable! Let's do that first But eventually we need to spread out, so our entire species isn't in one place in case of catastrophic events

We could keep it habitable, but that might not necessarily be in our control. We need a back up.

​@@johnjackson8709but there's no profitable way to keep Earth habitable. At least we shall go down in history of the universe as the Only species that couldn't save ourselves because there's no profitable way to do it. Every good solution for keeping Earth good isn't profitable anyway so we shall never do it☠️

It's in the end credits, MMVII/MMVIII.

🙊

I don't know if we can find water w got everything else we need to colonize

dementia is hard

Is it? Lol

@@AbortYurfetuses We can, if gov'ts spend enough money. All the other planets, humans can NOT land on.

@@KrustyKlown moons

We could travel to the twilight zone of Mercury if we figured out a super terrific radiation shield. Ya, I guess you are right. Rocky moons of the gas giants are the way to go. Jupiter craps out a load of radiation too, though. Anyways, you're right.

The worst of Planet A will always be better than the best of Mars.

Ok well you do your part and make sure you don’t have any children.

Or the Earth way instead. Our own is changing to kill life and be like others🤔

That makes ZERO sense.

Bro is high as hell

@@chongli3007 So am I. But I can still think semi logically 😂😂

@@drconflict629 I think he means.. the planet will eventually revitalize itself

I found it very interesting. No one forced you to watch it. You could easily fast forward or click off of it at anytime. So many negative people in this world.

watch it as you fall asleep.. it should send you into dreamland in no time

Intense solar radiation and cosmic rays due to lack of magnetic field will kill anyone. Mars' atmosphere is 95% carbon dioxide, 3% nitrogen, 1.6% argon. Earth's atmosphere is 78% nitrogen, 21% oxygen, 0.9% argon, 0.03% carbon dioxide. Mars has only about 0.7% of the atmospheric pressure of Earth. Mars' atmosphere is about 6.5 millibar, Earth's atmosphere is 1013 millibar. Surface of Mars is like Earth at 100,000 feet (30 kilometres) in the stratosphere. Mars' atmosphere's humidity is 0.03%, Earth's average humidity is about 50% (lowest 0.36%, high 100%). Intense ultraviolet solar radiation, due to thin atmosphere. Alkaline pH soil at 8.3, due to chlorine in the soil. Earth's average soil pH is about 6.5. Toxic. Virtually no oxygen at 0.13%. Earth at about 21% oxygen. Mars is covered in dry iron oxide dust, has seasonal global dust storms, with a duration of about a month. Mars' average global temperature is −81 °F (−63 °C; 210 K), Earth's average global temperature is 57 °F (14 °C; 287 K). The seasonal Martian polar ice caps are mostly dry ice, frozen carbon dioxide atmosphere (CO2). Comets falling on Mars bring some water and ice to Mars. The thin Martian atmosphere means the freezing, evaporation, and boiling point of water is all at the same temperature. Thus liquid water cannot exist on the surface of Mars .

“The sun is the past, the earth is the present, the moon is the future. ' From an incandescent mass we have originated, and into a frozen mass we shall turn. Merciless is the law of nature, and rapidly and irresistibly we are drawn to our doom” Nikola Tesla

I think we should focus on keeping present earth.... present earth!

@@johnjackson8709 Unfortunately there are greater forces than us at work....

It's asteroids we're avoiding

1.5 c seems to have happened quickly
