That’s so cool haha

can you add interferometers on satellites? - Sarah

Is the light being captured by the EHT from M87 being emitted by those jiggling electrons through synchrotron radiation?

What exactly is the orientation of the black hole in the picture with respect to its axis of rotation.

for imaging

Can we use the same technique of EHT to see the black hole in the center of our galaxy?

what might be the astronomical function of black holes?

Wonderful topic and presentation! Very interesting discoveries!

thanks!!

If just 2 satellites could resolve the electron ring, and a GEO orbit could increase the resolution 100-fold, would it be feasible to use Lagrange points (probably the L3 point) to have a solar system-sized telescope?

You mentioned how, to see the photon rings you dont necessarily need super great telescopes, just a long baseline. As such, can you have a earth orbit baseline by utilizing telescopes?

okay fine. what matt said instead.

What other objects would be good candidates for this type of analysis?

Also will this lecture be available to see if it's recorded?

Can you talk more on the photon ring? I missed how it is possible to separate out that light from the main image?

What would a black hole look like in 3d?

Thank you Dr. Johnson for the fascinating presentation!

Interesting, thank you!

that's cool!

Thank you! very interesting!!!
