Oumuamua: just a piece of rock

If you can watch the whole bit of this piece of New Age woo hoo without flinching or giving up, you will likely shake your head at the utter, mindless gullibility of humankind. And it’s not even political. But by now you know the Net is crammed full of conspiracy theories, pseudoscience, food fads, creationism, homeopathy and other claptrap. And you already have seen how the wingnuts can easily bend and twist everything, taking stuff out of context or simply making it up to suit their wacky beliefs.

The latest codswallop is that scientists claim a tumbling cigar- shaped (or was that penis-shaped?) chunk of rock that passed through our solar system in October was actually an alien spaceship. Well, no, they didn’t. And they certainly did not CONFIRM anything of the sort no matter what some UFO-addled wingnut claims.

Oumuamua – or more technically, 1I/2017 U1 – zipped by us about 33 million kms away, reaching a speed of 87.71 km/s (196,200 mph) before slowing. The eccentricity of its path made astronomers hypothesize that it came from outside our own solar system and thus was the first recognized interstellar traveller we have encountered. That’s only a hypothesis based on its trajectory, not even a full theory yet, because no one has seen it close up, let alone sent a probe to examine it closely. And never will.

The minimal data available says it’s a chunk of rock, roughly 180 by 30 meters (600 ft × 100 ft) in size. Even if it did come another stellar system, and even if it’s oddly shaped, there’s nothing to indicate it wasn’t natural.
