Is This Why Earth Has Life And Mars Doesn’t?

this will make you THINK…

Have you ever wondered why Earth supports life and Mars does not?  You may or may not know about this but Earth’s magnetic field plays a super important role in this.  We often focus on things like the atmosphere and the cellular level communicating with each other through DNA.  However we are protected by an extremely sophisticated system that few people talk about:

Earth’s magnetic field, which protects the planet from harmful blasts of solar radiation, is much older than scientists had previously thought, researchers say. In fact, this invisible, protective shield likely existed shortly after the planet formed — a finding that could shed light on why Earth is habitable and Mars is not.

Without Earth’s magnetic field, solar winds — streams of electrically charged particles that flow from the sun — would strip away the planet’s atmosphere and oceans. As such, Earth’s magnetic field helped to make life on the planet possible, researchers have said.

Here is some more in depth information on how this incredible “field” actually functions:

The magnetic field is generated by swirling liquid metal in Earth’s outer core, and this “geodynamo” requires the release of heat from the planet to drive its churning. Nowadays, this heat flow is aided by plate tectonics— the movement of the plates of rock that make up the planet’s exterior — which efficiently lets heat transfer from Earth’s interior to its surface.

Now, scientists have found that Earth’s magnetic field could be up to 4.2 billion years old — about 750 million years older than had been previously thought.

The researchers investigated magnetically sensitive minerals such as magnetite, a naturally occurring cousin of rust. As molten rock cools, magnetite within it becomes literally set in stone, pointing to the location of Earth’s magnetic poles at the moment it froze. As a result, the oldest samples of magnetite can reveal the direction and intensity of Earth’s magnetic field at the earliest parts of Earth’s history, the researchers said.

Do you think they are right…is this THE factor for an inhabitable planet?

    I might have to unfollow shockingscience.. im kinda breezing thru their site and it looks like it’s run by christians.. I saw this story and thought maybe there was a new field surrounding earth. Turns out.. I already knew about this in 1974 and somehow this seems fishy to me..

    Adam Asing you are ignorant.. we alrwady know about flat earth.. now that we have technology.. like the computer you possess.. flat earth is a myth.. get in an airplane.. youll see.

    So adam.. answer me this. When you go to the edge of earth and keep proceeding.. what happens?

    Adam Asing sorry. I have a A1 education with honors.. of course toull answer with other peoples answers because you have no fucking life or intelligence to come up with a retort of your own. This makes you truthfully ignorant. Your not willfully ignorant because that would compliment you.. you are just plain ole fucking stupid..

    Topher Faulkner why waste intellectual debates with a closed minded entity. Who believes all you tube vids. Theirs no depth, nor capacity for challenging a higher register of knowledge. Most of the things this science link gives. Are leading more and more to misleading and geared towards prying open ignorant debates of master keyboard blackbelts..lol. Just choose your battles wisely. Dont waste time with uneducated entities.

    Adam Asing I will humor you with the notion that I am highly openminded. I have done many studies into the acclaimed flat earth theories. Also on the Hollow Earth theories. Etc. But to debate with you on this is an extreme waste of my time. If you honesetly still believe in earth being flat. Than you really to reevaluate the credability of where you recieve your information and reeducate yourself on many principles and fundamentals of a sphere. Let alone earth.
