Radiation Will Tear Elon Musk’s Rocket Car to Bits in a Year

Plastics expert Dr. William Carroll of Indiana University says Elon Musk’s Starman Tesla is no match for the rough-and-tumble environment of space.

The real forces that will tear the car apart over hundreds of millions of years in space, Carroll said, are solid objects and — most importantly — radiation.

Even if the car avoids any major collisions, over very long time horizons, it’s unlikely the vehicle could avoid the kind of collisions with micrometeorites that leave other space junk riddled with craters over time, Carroll said.

But assuming those collisions don’t completely tear the car apart, the radiation will.

Down on Earth, a powerful magnetic field and the atmosphere largely protect human beings (and Tesla Roadsters) from the harsh radiation of the sun and cosmic rays. But spacefaring objects have no such protections.

There are two Americas, and one of them is stupid

I was doing some online searching for a friend with whom I worked a long time ago, so I put her name into The Facebook to see if she was around. A woman with the same name came up in the search results. She was about the same age, listed as “retired,” and looked somewhat similar to how I imagined my friend to look now that twenty-five years have passed since I saw her last. Perusing this woman’s post soon convinced me this wasn’t the old friend I was looking for. In fact, there was this galling comment on this news story that made my jaw drop. It was on this BBC news story about the Lincoln Memorial being vandalized:

“What more do they want?”

“This is getting ridiculous,” she writes. “Lincoln freed the slaves – what more do they want? Oh I know – to erase America’s history!”
