Journey To The Center Of The Earth

After watching Journey to the Center of the Earth, I learned that muscovite is very thin rocks. The slightest change of weight will make it break. I learned that magnesium is very flammable. Lastly I learned that adventures can be very dangerous.
Three things that I learned were not really true in Journey to the Center of the Earth are that the glowing blue extinct birds are not actually glowing, dinosaurs are not still alive like shown in the video, and you cannot go to the center of the Earth.

MY FAVORITE TOPIC!!!!!!!!!!!!!!!!!!

My favorite topic in Earth Science was astronomy. I liked learning about black holes, and I wish I could have done black holes for our astronomy choice projects. I think that it is pretty cool that anything that falls into a black hole is instantly crushed. I also think it is kind of interesting that stars with three solar masses can turn into a black hole. The fact that no light can escape a black hole is simply fascinating. =D =D =D =D =D =D

Big Bang

I think the universe was just a great big open space of nothingness. You could not see a thing. The universe went under an initial inflation that was very quick and was almost instantly how we see it today. However, this is just a theory. =D

Optical Detection

Four ways that astronomers can detect extrasolar planets are by radial velocity, astrometry, transit method, and optical detection.

In optical detection you can block out the star's glare using a physical mask called a coronograph. The cornograph hides everything except for the stars corona so you can see the other planets.
I have looked over many websites and I have not found any information that tells me how many extrasolar planets have been found through optical detection. I honestly cannot really even find anything about optical detection.
