Heres responses from classmates: I enjoyed learning that the earth and moon were helped to be formed by colliding with Theia. Interesting that could be the cause of life on this planet and creation of the moon Luna.

I totally agree, I thought it was cool that a collision could have caused live to form! It seems so simple in theory.

Hi Scott, I also found it really interesting that the earth and moon is what it is today because of a collision with the planet Theia! I think it's really interesting how the destruction of two planets, something you would think as tragic and bad for the planets actually made something that we would not be here without(modern earth)

Hello Scott, I also found it interesting to learn that the creation of the Earth and the moon was due to the collision of Theia and later on created life. This made me wonder if something similar could have happened to Mars since Mars possesses similar qualities to Earth.

I'm glad someone else found that so interesting!  It seemed so interesting to me that the potential reason for life's existence on this planet is based on the happenstance of another planet colliding with Earth at such a 'young' age.

I found it very interesting and confusing how the universe is 13.8 billion years old but humans are only 200,000 years old. I wonder how we know the universe is 13.8 billion years old when humans have only been around for 200,000 years.

I also find this very fascinating! I wonder what everything in the universe looked like before we were here. There was so much time before us so there's probably a lot that took place that we have no idea about. Perhaps different species, planets, etc. existed that we will never know about. I'm hoping we learn more about this in class.

I agree, I think it’s every interesting how far we can trace back into earths past, billions of years before humans were once here. I think technology is interesting, and can be scary. I think as technology gets better, we will figure much more about earths history and how we came to be. I think the question, how we came from no life, to life ? on earth is so interesting. It’s so simple but so complex and important to our earths history.

At first the analogy between apple pies and planets really confused me but it was really interesting to see how minute every aspect of our world is. Then to apply the same analogy and realize we are one tiny part of a universe that we haven't explored and simultaneously, that universe is still expanding is really astonishing to me. It was really interesting to hear about the planet Theia and how much that impacted the life on Earth and the formation of the land masses upon Earth. I am curious to know if we can definitively know how much Theia actually affected the topography of the Earth?

I also had a similar questioning on the total impact that Theia has caused to the topography of the planet! It kind of had me questioning whether or not if we would ever get that answer. To think that a collision with another planet would cause the way of living today.

One thing that I found to be interesting from this week's lecture was the idea of how atoms came to be. I found it very interesting that it took almost three minutes after the Big Bang before the first atom was formed. I found that interesting because I had always figured that once the big bang happened it would have been a much shorter time than three minutes before the smallest unit of all matter was formed, especially since the electrons, protons, and neutrons were formed just seconds after the big bang and these are what makes up the atom.

That the overall radius of the earth is 6471 km. I wonder how they got that is since the earth is a geoid.

I found it both surprising and interesting that there are so many elements that can only be produced via super-novae. I also found it interesting that there are so many different ways to create elements in general. It's probably an advanced topic that I'm not really ready to learn but I'd definitely want to know why they can only be or are mostly made by these processes.

Something interesting I learned this week would be about the collision with Theia. In previous biology, chemistry, and even anthropological sciences I was never taught that the earth had collided with another planet and because of this, that is why we have the moon. I also found it interesting that the Earth (or Porto Earth) was once the size of Mars and after colliding with Theia the dense elements that didn't get blasted to space stayed on Earth and mainly formed the earths core. 

 

A question I have regarding the lecture is how we're able to to find out what was inside each layer of the Earth and conclude that the inner core is Solid Metal and that the outer core was Liquid Metal and so fourth with the mantle. I also want to understand what is the purpose of stars because  after learning that stellar nebula produced hydrogen and formed stars it makes me believe that there is a purpose since hydrogen is very important to our survival.

1. I found it incredibly interesting how there were multiple instances of violent events causing creation. For example the Big bang causing the creation of atoms and the creation of both the moon and the earth by colliding with Theia. Its interesting that these things that we usually associate with destruction can also be associated with the creation of so many things.

 

2. Funny enough I actually had apple pie for desert with my family yesterday while we played games.

 

3. I had no questions about any of the covered materials

1.  I found the hypothesis,  that the collision of the Earth and Theia may have led to the possibility of life on Earth, to be very interesting.

2.  Seeing the periodic table again gave me flashbacks to my high school chemistry class where we had to memorize it, not a good memory.

3.  I didn’t have any questions on the covered material.  But I do wonder what Earth would be like today, if it had never collided with Theia.

Something I found really interesting in this weeks lecture was that certain elements, like gold and platinum, aren't formed on Earth. They aren't even formed in our solar system, but rather by a super-novae event. This is a really cool and new idea to me that I hadn't heard of before this lecture.

One thing that I found very interesting from this weeks lecture was how old the Earth is. It was stated that the Earth is 4.6 billion years old. It was also stated that humans have only been around for 200,000 years and civilization for only 6,000 years. I wonder why it took so long for human life to develop on Earth and how we are progressing so quickly now that we are developed civilizations on Earth today.

1. It was interesting to me just how quickly atoms formed after the big bang, I guess since we were always taught that energy cannot be created nor destroyed, is that not really defying that which we've been taught for so long? 

2. Honestly, at night since I live pretty much in the middle of nowhere, I like to walk outside to see the stars at night, so the pictures on the lecture slide was cool looking at.

3. What exactly was there before the big bang?

One thing I found interesting was the earths age. Earth has been around longer than humans. And how that came to be can be confusing. I also liked learning about the earths crust.
