This series is a great revamp of the traditional turtles title. In this issue a scientist makes Metalhead, a robotic turtle with A.I. The scientifically interesting part about this robo-turtle is it has an anti-gravity gauntlet!
Questions: 1.) What do we know about gravity? 2.) Do we know anything about making anti-gravity weapons?
Answers: 1.) We know quite a bit, which just shows us how much we do not know. All great discoveries pose more questions than they answer. Currently, it is seen that gravity warps space-time for example: hold a blanket on all corners and put a bowling ball in the middle. Gravity distorts that space. Also, the effect on us is that it pulls us toward the mass. Earth's gravitational pull is 9.81 m/s^2. Below, is a link to new research in gravitational waves and a link of a brief explanation of gravity. http://phys.org/news/2014-06-gravitational.html http://math.ucr.edu/home/baez/physics/Relativity/GR/gravity.html
2.) I have read nothing to indicate we are even close to knowing enough about gravity to be able to manipulate it into a weapon. Being able to manipulate gravity would be revolutionary! We could finally have build a Cloud City as seen on the planet Bespin in Star Wars V.
