I'm wondering if it's possible to use the @ehtelescope to find out more about the #WowSignal.
And while we are talking about the #WowSignal: I have an alternative speculation for it besides aliens (although I still think it actually has a natural cause we haven't found yet, so don't get too excited): us from a parallel timeline somehow sending a spacecraft in the past.
There are possible indications why it could be us and not aliens. The first indication is that the #WowSignal didn't last long. If it really was aliens trying to contact us then why did they seemingly only send this signal for a short time and not continuously?

I'm literally abt to hop on a plane for the rest of the day, but here are a few things that make this #EHTBlackHole press release monumental to me from the perspective of an astrophysicist who studies active black holes.
1. It's still true that we can't *see* a black hole. What sight-abled folx are seeing in this image is the shadow of the black hole (what I typically call "SOS" signals from the material about to fall onto it). This process of material infall onto a black hole is called accretion
2. We've observed black holes for decades using the fact that infalling matter releases copious amounts of radiation (light) before crossing the event horizon. Black holes dominate high energy light like X-rays bc of accretion. This is a composite image of M87. @NASAHubble
