Hi, I'm Jay and I'm new to Physics Forums. I'm an undergraduate student studying physics and computer science. I was wondering what your thoughts were regarding the following photos I took on Google Earth. Edit reason: Maximum number of photos. Thanks very much. My personal opinion is that whatever the structures and patterns that are underwater, they are not created by natural processes because natural processes are "nonlinear" in their nature. For example, a mountain, canyon, ridge, or pattern in nature generally shows a fractal-like self-similarity that makes its features rough and bumpy rather than smooth and patterned distinctively. I'm looking forward to your impressions and thoughts and a lively debate.
