UFO

As a scientist I am open to all possibilities when it comes to UFO's but if they are here there are some important laws of physics of which we are currently not aware. This in and of itself should not be surprising since civilization started here some 4,000 years ago and their are planets out their that are billions of years old. What will earthlings learn over the next billion years. Fiction stories talk about warp speed and worm holes to traverse the cosmos in fast time. While there is no way to explain how aliens could get using our present knowledge of physics it does not preclude the possibility. For now I will stick with some explanation from the government based on current physics unexciting as that may be.
