Last week, scientist made a significant step forward in developing an honest-to-god cloaking device.
Now, it doesn't take a great leap of the imagination to imagine Big-Dog outfitted with a cloaking device. Not that you still wouldn't hearing him coming from a mile away... but you wouldn't be able to see him! Imagine the terror! Surely we're doomed, right?
Fortunately at the moment, this technology is only limited to things that are microscopic. Yes, you heard that right. We can make things that we couldn't see anyway invisible.
Color me impressed.
