Hi Damon,

This is a wonderful essay. The title is enigmatic and attention grabbing. It tells the reader very little about what the essay is actually about. It also says something that shocks the reader. Either way the reader will begin to read right away to find out more. You launch into the essay without introduction or preamble. This takes all the reader's attention and focuses it completely on the topic and the essay. They will read to the last word. You have written about two separate theories of gravity. You have done your research here. You are conversant with your topic and easily make it comprehensible for your reader. The length is perfect. You completely develop your topic without belaboring the issue and making the essay tedious. I applaud you. Most scientific pieces are not like this. I did come across one structural issue that needs your attention:


1)Imagine a man on a speeding train and he is sitting in front of a large window.-There should be a comma after "train".

You use a formal, organized style that is very appealing to the reader. Great job.
