I read somewhere it must’ve turned molten from the atmosphere, but l wonder if like little droplets of metal fell down to earth or if it was just vaporized.

The high speed camera was intended to be used to calculate the speed of the cap. It was going so fast it was only captured in 1 frame, which is only enough information to put a lower limit on the speed.

How do you calculate speed at all with only one frame?

It was a lower bound. It had to have been traveling fast enough to only be captured in one frame.

Gosh, the one frame probably didn't even have a reference time to work from.

You dont, hence why only a lower limit could be established with a single frame capture.

Basically like saying "if we only got 1 frame, then it must be going faster than x mph/kph"

Distance between not moving and gone compiled against recording timestamp and detonation.

It's, not very accurate. But you do get a lower bound.

Showerthoughts

A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The most popular seem to be lighthearted clever little truths, hidden in daily life.

Here are some examples to inspire your own showerthoughts:

Rules

  1. All posts must be showerthoughts
  2. The entire showerthought must be in the title
  3. No politics
    • If your topic is in a grey area, please phrase it to emphasize the fascinating aspects, not the dramatic aspects. You can do this by avoiding overly politicized terms such as "capitalism" and "communism". If you must make comparisons, you can say something is different without saying something is better/worse.
    • A good place for politics is c/politicaldiscussion
  4. Posts must be original/unique
  5. Adhere to Lemmy's Code of Conduct and the TOS

If you made it this far, showerthoughts is accepting new mods. This community is generally tame so its not a lot of work, but having a few more mods would help reports get addressed a little sooner.

Whats it like to be a mod? Reports just show up as messages in your Lemmy inbox, and if a different mod has already addressed the report, the message goes away and you never worry about it.
