If it can convert vibration into electricity, does this imply that it would be a good sound-dampening material (for smaller space requirements than e.g. foam?)

Alternately, would this imply that it would be a good solid-state microphone?

There are solid-state microphones, based on piezoelectric materials

They say it's magnetic rubber, which would explain movement to electricity, but light? How can magnets capture light energy?

Electron excitation

I wonder what kind of applications this could have beyond robotics. Could material like this be used in space?

In space, electricity is always welcome, while vibrations are usually not. So to the first approximation, sure, why not?

So Vibranium is not a metal after all!

Is there a paper?

There are a bunch here: https://www.researchgate.net/profile/Kunio_Shimada

This guys's research history: I love magnetic fluid and I'm not tired of trying new things about it.

It's fascinating how people's obsession with obscure things yield scientifically significant results.

Your network isn't referring to /your personal/ network. The filtering is more likely ASN wide (i.e: targets entire netblocks / ISPs).

There sadly are a lot of ISPs who are known to ignore abuse reports completely leading to issues like these.

This reminds me a bit of how flubber works in the 1960s Disney movie "The Absent-Minded Professor".
