How many are the ways a Black hole without *ACCERTION DISK* can be spotted?
So, we are no longer expecting the OP to do some work before we give answers? Did you think ibix was not aware of these?A couple other ways I can think of:
1. Orbits of stars nearby.
2. Gravitational micro-lensing.
3. Gravitational waves (if two black holes are orbiting each other).
4. Sending in TARS or CASE.

And I had to Google this one -- I learned something new!4. Sending in TARS or CASE.
No need to redact now that the OP has seen it. But yes, a common theme lately has been to try to get (especially new) users used to showing their efforts when they ask questions.
Great to have you back, @Matterwave -- you have been missed!![]()
Sorry, I didn't realize you had been away for a while. I though you were just forgetting the standards for a moment.Ok, I will keep this in mind in the future. And, thanks! :D
