They forgot "is it followed by a bright flash and mushroom clouds?" → nuke, so grab some whiskey and make your peace because you're probably too close.

This flowchart is missing "Swamp gas from a weather balloon was trapped in a thermal pocket, and refracted light from Venus"

Is "fireball" a technical term here? Because I only know the wizard kind and they do end in a dramatic explosion.

"Fireballs and bolides are astronomical terms for exceptionally bright meteors that are spectacular enough to to be seen over a very wide area. ... A fireball is an unusually bright meteor that reaches a visual magnitude of -3 or brighter when seen at the observer’s zenith. ... Fireballs that explode in the atmosphere are technically referred to as bolides although the terms fireballs and bolides are often used interchangeably."

What if Alexander Gerst is waving a flashlight at me from his boat in a downward u motion?

Not really big, slowly blinking and regularly burning my retinas

[–] Potatos_are_not_friends 1 points 5 months ago (2 children)

I don't know if this is real or a joke meme. The blinking bit makes it sound real for identifying.

And what does it mean by boat?

[–] psud 2 points 5 months ago

Boats and ships have lights. A sailboat at anchor has a white light at the top of the mast, which might bob around a bit as the boat moves in the waves

Obviously a joke, can you see astronauts wave? "Everything" twinkles, not just stars, since the atmosphere causes that.

[–] [email protected] 1 points 5 months ago

SNe?

[–] [email protected] 1 points 5 months ago

What if it's big and moving? And burning my retina too ?

[–] over_clox 1 points 5 months ago
