What type of pillow can stop a meteorite is what I'm wondering. Sure the roof may of slowed it enough but for it to still be intact from that and at that size, it would of been dense to make it that far without breaking up or burning up and I'd of expected a more substantial roof would be needed to slow it. Then the final detail, It would still be pretty darn hot.
So I'm somewhat sceptical.

- s5300 5y agoDon't check the internet tomorrow if it ends up being a MyPillow.
- vnchr 5y agoSounds like it may have hit the mattress before rolling between the pillows, and the photo and title are mildly sensationalizing with hitting the pillow directly. > “…I rolled back one of the two pillows I'd been sleeping on and in between them was the meteorite."
- marcodiego 5y agoI won't make numerical estimates here, but we can consider that: - the piece of meteorite had already achieved terminal velocity, - most of the remaining energy was lost on the collision with the layers of the roof and - final collision was dampened by the pillow, mattress foam and bed structure. By the size of of the object on the photograph, if it has approximately the same density of earth stones, the story seems 100% believable.

- consumer451 5y agoThis NASA document explains very nicely how a series of thin shields can provide more protection than one much thicker shield layer. Of course, the velocity is much lower once in the atmosphere. https://hvit.jsc.nasa.gov/shield-development/ https://hvit.jsc.nasa.gov/shield-development/
- throwaway0a5e 5y agoI suspect they're trading an obscene amount of space to save weight (because space). There's a reason (the reason being they tested this stuff 1.5 centuries ago) pretty much no armored vehicle or vessel uses armor with empty spaces in between.
- jazzyjackson 5y agoIt’s called “spaced armor” and there’s a whole wikipedia article detailing its use in the last century of tank design. Army wants to save weight too btw, they do fly these things in after all. https://en.m.wikipedia.org/wiki/Spaced_armour https://en.m.wikipedia.org/wiki/Spaced_armour

- tshaddox 5y agoAssuming meteors can have any initial size, speed, and entry angle, there must be some sets of those initial values such that a remaining meteorite of the size seen in these photos could go through a roof and land on a bed. It doesn't seem possible that there would be any step function where if it doesn't burn up completely and can make it through a roof it must be going fast enough to also go through a pillow.
- jimmygrapes 5y agoI'm really kinda hoping it was a MyPillow so that my afternoon local radio ads turn into METEORITE PROTECTION
- sengstrom 5y agoalso possibly quite hot from recent interactions with the atmosphere
