I noticed this meme a few days ago. I recognized the “friend of a friend who has insider knowledge” formula that makes people want to share a memes. I know better than to trust anonymous online sources that claim to have special knowledge, so I just re-read what the CDC says and moved on. Here are links to what the CDC says: Symptoms of coronavirus How to protect yourself How…

Rewatching ST:TNG This flipside episode, told entirely from the viewpoint of a civilization on the verge of discovering warp drive technology, documents a visit from members of a federation of space-faring aliens who wear brightly colored pajamas.
