How grand to be a mathematical pirate! To sail by trigonometry alone. Shoot cannonballs in elegant trajectories...

That demonstrate the sections of the cone!Its from this YouTube video. It's so punny!!!https://youtu.be/i3htrFWoz_w

Forget all that. Just tell me how I can time travel using Einstein's Theory of Relativity. (I know I can't go backwards.)

Trust me, the History channel is the Conspiracy Theorist channel. It's all bullshit. Trust me, I'm planning on getting my degree in astrophysics/astronomy.

I do trust you because you're obviously very smart. But there's so much evidence (Hangar 1 is about MUFON which has over 70,000 case files) of alien visitation that it's not bullshit.

Let me link you to a particular xkcd that describes why it's all BS:
https://xkcd.com/718/


On top of that, think about it. While alien life most certainly exists, only a fraction of it would contain life intelligent enough to leave the host planet. Life intelligent enough to leave its host planet and host solar system, however small that fraction of life out there represents, would have a hundred billion stars minimum out there in our galaxy alone. Life that is capable of interstellar travel would also be capable of intergalactic travel, so it doesn't make sense as to why it would want to stay in its own galaxy. But even in our own galaxy, imagine sitting on a beach, and picking a grain of sand at random from that beach. Picking our own solar system would be less likely to happen than if you picked the grain of sand that was sitting on the tip of your finger. Now imagine that these aliens know where the intelligent life in our galaxy is. See all those black flecks of "sand" on the beach? Let these represent the stars with intelligent life around them (they're actually organic matter so it makes the analogy funnier than if it was orange sand or something). Pick one at random. The chances are of you picking the one in your hand are more likely than the chances of picking the Sun out of the rest of the stars in our galaxy.


Now recorded human civilization has only been around for roughly 6000 years. Prior to that, we didn't really have a method to write things down and record them. Even then, even if an alien did decide to visit Earth, it is first of all, most likely to be via a probe that may have crashed and burned, missed Earth entirely, or subducted before we could discover it. Out of the one billion years Earth has harbored life (4.6 billion years in the making total), the chances of an alien visiting earth is probable--but only across that entire timespan. 6000 years doesn't make a dent in that. Imagine you have, say, three darts to throw at a dartboard at random (you can't aim) that represents the time life has existed on earth.


Let each year be represented by a square millimeter. Your dartboard is one square kilometer. You're throwing at random and hoping to hit a dot that has an area of six square millimeters. The chances of this occurring are slim to none.


I met a guy that was adamant that he saw an alien... when in reality, it was just a Geminid meteor. He described it to me: "Three green streaks zipped across the sky, following each other, one after another." During the time of the Geminid meteor shower. Which are typically green, appear in bursts, have somewhat long tails, and appear to follow each other occasionally.


People that believe they saw an alien encounter usually don't understand basic astronomy/astrophysics and meteorology. If it's not one of those, it' s likely a military thing or another natural phenomenon like St. Elmo's Fire.
