is because of its journey, as its journey during all these billions of years. It's passed other star systems, it's probably passed other solar systems as well. As it's doing this, it's getting a gravitational assist. The gravity is sucking it in closer and closer to these systems and allowing it to be propelled out at an even faster speed. So it's a kind of a runaway effect, you might think. And by the time I got here, it was traveling along at some incredible speed, so that led up to some of the speculations about it being of alien origin. And there was some issue, too, about its trajectory, some issues about that. But the trajectory on it was in line with its speed and where it was actually coming from. And then, of course, radio transmissions coming from it. That also led to some speculations about it being of alien origin, radio signatures and frequencies coming off, but we're just the interaction of the chemicals that were being sublimated off its surface, interacting and giving off radio signals. Hydrogen was one of them, oxygen was another.
