What Can We Learn By Drilling Into The Earth's Mantle?

Scientists have just discovered something deep in the earth's crust that could tell us a lot about outer space. What exactly did they find?

Orcutt's Expedition Finds Signs of Life in Earth's Mantle
"An international team of scientists - recently returned from a 47-day research expedition to the middle of the Atlantic Ocean - have collected an unprecedented sequence of rock samples from the shallow mantle of the ocean crust that bear signs of life, unique carbon cycling, and ocean crust movement."

A Decades-Long Quest to Drill into the Earth's Mantle May Soon Hit Paydirt
"Since the 1960s, researchers have attempted to drill into Earth's mantle but have not yet met with success. Nevertheless, those efforts have shown that the technology and expertise to drill to the mantle exists. And now the first phase of the most recent attempt to reach this important part of our planet is boring through a thin section of ocean crust in the southwestern Indian Ocean."

What's at the Bottom of the Deepest Hole on Earth?
"Soviet scientists in the 1970s decided to probe deeper than humanity has ever done before. For the next 24 years, they drilled on and off into the Earth's crust. The result was the Kola Superdeep Borehole and a drill-depth of more than 7.5 miles (12 kilometers)."

We can learn that the center of earth is made of cookie dough.

just receive a phone call from the Mantle. she said to leave her alone her secrets are hers to keep and that's her diamonds you greedy earthlings!

[pharmit]

She's like a smart version of iJustine.

lisette! been a fan since you were on tytu, and I'm actually rewatching your appearances on your playlist (thanks for that). would love to see you in those more relaxed discussion/opinion type videos again. really like how your quality shows; eloquent, fair, observant, and just generally nicer than the other hosts in a John Green kind of way--but with cursing--if that makes sense:D. always glad to see you!

[Jeremiahking]

Lol id love to see a reactions video of these girls when they read comments about them

[-ig]

We learn that we can mess with the earth even more!!!! :D

[calsta]

Thank you for using the metric system as the base, next you can start saying further instead of farther.

"why are we trying so hard to get down there" giggity

[ntb]

love your videos guys, keep up the good work ;-)

[urinstein]

Kinda strange seeing her talk about something that is not terrible... without the sad music.

[cultibotics]

Interesting use of closeups. I like it!

[cupcakequeenjj]

Thank you so much that has helped me with my homework

[rogerkreil]

I will have to look up the underground ocean now!

Instantly thought of the film The Core. Amazing film.

I feel like if we were to reach the mantle, they pressure would have been built up so much that some of the mantle would come to the surface and cause some serious damage

There's also a lot of energy down there since where there's heat there's energy. In addition to scientific discoveries, I'm wondering if getting down there could also provide us with another source of energy since so many people are opposed to solar, wind, and nuclear.

[ShawnRavenfire]

Then we drop in a nuclear bomb and hold the earth ransom ONE MILLION DOLLARS!

does pressure increase as a first power function when going deeper towards the mantle

[turbofart]

Wow am I the only one who thought it was great to here Tara's voice at the end of this video?

People should try to understand that if there is extraterrestrial life out there...
That does not mean they are similar to animal or bacteria we have in our planet.
