In a recent article released on Science Daily (http://www.sciencedaily.com/releases/2013/04/130425142355.htm) states that the earth's core is said to be 6000 degrees Celcius which is 1000 degrees warmer than what was proven 20 years ago. Although science has changed from 20 years ago, Agnès Dewaele from the CEA says that "In practice, many experimental challenges have to be met,"and that the experiment could be flawed because there has yet to be an accurate way to measure the temperature of the earth's core. Even if a sample reaches the extreme temperatures and pressures at the
centre of the Earth, it will only do so for a matter of seconds. In this
short time frame it is extremely difficult to determine whether it has
started to melt or is still solid." he states. As he continues to talk about the expierment he hopes that science will develop enough where there are little to no flaws in the expierment.
I think this article is a great example of how fast science is growing and how much we still need to learn about the planet we live on. It is also a great goal for scientists to reach to try to perfect the experiment and know more than we've ever known before.

Caroline. I really like this post. I think that you put a lot of thought into it and you clearly understand what you are writing about. I like how you included the element of how we need to protect the planet.
ReplyDeleteEveryone knows that the Earth has an extremely hot center but I didn't realize that it was 6,000 Celsius hot (I wonder what that is in Fahrenheit). Since it is extremely difficult to determine the temperature of the Earth's center, how close is this new number to accurate? Will we ever find out what the actual temperature of the Earth's core is? And your reasoning for how this effects science is superb.
