Comets

Comets are fascinating to me. I’ve only seen a couple, but pictures of them are gorgeous.

It’s really interesting that they grow a tail as they get closer to the sun. How they grow it is even more wondrous.

Comets are basically big balls of ice and other stuff zooming around the sun. As their orbit takes them closer to the sun, the sun’s heat melts the stuff on the surface of the comet. The closer it gets, the more gets melted.

Additionally, the sun’s radiation is always flowing outward from the sun. This is sometimes called the sun’s solar wind. This wind, as the comet gets closer, takes the melted comet residue and blows it off the comet. It is this residue flowing into space that becomes the comet’s tail.

Now, if you think about it, that residue is leaving the comet, rather permanently in fact. But, comets have no way to replenish themselves. So, eventually, they wear away to nothing.

Thus, after a period of time, there should be nothing left of the comet. And, this period of time is less than 100,000 years.

But, if the solar system is billions of years old, and any comets die after less than one ten-thousandth of that time, they should have ALL died.

But, they keep showing up. So, the obvious conclusion should be that the solar system isn’t as old as we’re told.

But, the narrative doesn’t change. We’re still told the solar system is billions of years old. How?

Scientists invented two concepts to explain it: the Oort Cloud and the Kuiper Belt. The Oort cloud supposedly drops comets into orbit around the sun if the comets have orbital times greater than two hundred years. The Kuiper Belt does the same for comets orbiting in less than two hundred years. Halley’s Comet is one such short-period comet.

Where’s the evidence? Drum roll, please … there is none. Both are constructs to explain comets, but they lack evidence.

Worse than that, for short-period comets, the Kuiper Belt is actually inside the orbit of Pluto. And, we’ve been there.

But, there’s just a teensy problem: there’s no Kuiper Belt. There’s nowhere near enough space junk to turn into comets in the numbers we see.

Scientists have recognized this, but they don’t have an answer. But, they’ve pretty much retired the concept of a Kuiper Belt. It was a decent idea, but it had no evidence. And, now we know for a fact that it doesn’t exist. So, the space junk pieces are now called trans-neptunian objects, or objects outside the orbit of Neptune.

Folks, the implication is clear, if uncomfortable to them: the solar system isn’t more than ten thousand1 years old.

  1. It’s ten thousand rather than one hundred thousand because the larger figure I quoted above is for all comets. But, short-period comets come around the sun a lot more often, so they can’t be more than ten thousand years old.
