What If We Revived Mars With Water? 🌊🔴 | What If a Needle Slammed Into You?

[00:00:00]What if we took all of Earth's [screaming] water to Mars? We'd need six quintillion liters of water for Mars.

[00:00:07]Woah! Could my atmosphere come back?

[00:00:09]>> Yeah, and maybe you could become a living planet again. Nice try, but that's not how it works. Without a magnetic [music] field, Mars can't hold an atmosphere. That's why the water would either freeze or boil away.

[00:00:22]>> So, maybe a nuclear bomb is the only option.

[00:00:24]>> What if a needle [music] slammed into you?

[00:00:27]A tiny needle can't hurt me. But what if it hit you at full speed? Still laughing? Let's say at almost the speed of light. It could tear Earth into pieces. But it would release 201 billion million joules of energy. That's equal to three nuclear bombs.

[00:00:46]But my atmosphere would burn it up first. Hey, when is it going to die?

[00:00:50]>> It loses millions of tons of mass every [music] second.

[00:00:53]>> And he'll die in about 5 billion years.

[00:00:56]>> I am the most massive [music] star in the universe, and I lose 7 million times more mass than the Sun.

[00:01:02]>> That's equal to about 13 moons every year.

[00:01:05]>> Then you haven't seen quasars yet. I lose the mass of 10,000 Earths every second.
