They turned out to be someone heating up their lunch and opening the microwave door while it was still on.
This is probably something similarly mundane.

The Earth IS accelerating towards the sun, at about 0.0059 m/s². The earth is also moving sideways fast enough that even though it is accelerating towards the sun it doesn't get any closer to the sun. That's what an orbit is: moving sideways fast enough to cancel out falling.
Not even science is perfect... although the physics studied by scientists *IS* perfect, and the more they study physics the closer they get to knowing how it works. That's science. And thanks to scientists discovering this error, we just got another bit closer.
p.s. not just physics, obviously. Science is great for working out other stuff too.
"An umbrella, having no walls, definitely counts as outdoors"
Definitely is a strong word. What about an umbrella in a two-walled hut?
While we're at it, what about a one-walled hut inside a one-walled hut: does that add up to the two walls required to classify it as indoors??
Can we even be indoors without doors???
