Currently my favourite time wasters are learning channels on youtube. Especially not the "weird" ones like VSauce because I think those are pretty unwatchable. I like SciShow / SciShow space even though that's borderline weird :)

My current fav is Sixty Symbols, endless very interesting videos: https://www.youtube.com/channel/UCvBqzzvUBLCs8Y7Axb-jZew

Also PBS Space Time, MinutePhysics, MinuteEarth.
