But I'm going for Albert Einstein. He developed a theoretical framework for gravity before the observations that confirm it were made. When general relativity came out it was counter-intuitive to how we thought the universe worked. In fact, they had to devise experiments and do many further observations to see if this "crazy" theory would hold up. The bending of light by the Sun and galaxy clusters, gravitational lensing, time dilation, black holes, gravitational waves continue to confirm his theory.

Yes Rob so good to have your input
thank you for contributing.
I think "they" have gravity wrong which I hint at along side my photo..my opinion only.
And as you say it really takes something to work any of this stuff out...
I have said it many many times but the fundamental problem I see is gravity is seen as a force of attraction..well perhaps not really given General Relativity treats it as not a force at all...so one cant point to what I said and say I am wrong but other than I see gravity as a force in the first place, which is the wrong bit really
I think as old as it is (1745) LeSages "Push Gravity" is a most logical approach as to how it works.
Think of the galactic rotation curves, intuitively please as I have zip math skills, what we observe is most consistent with the rotation being driven by an external force...anyways that is the way I see it and my only claim claim to fame is that I am rather good at working out how things work..and if you want something to disagree with take the Suns Corona.. so much hotter than anyone can explain...if we have a push gravity type environment it would mean the energy from the Sun interacts with the "particles or energy" coming from the rest of the Universe (that provides the mythical pushing force) and if so what could we expect?
Anyways I recognise this is just mere speculation and will remain so until some one can provide a model...and that is the thing to remember..we talk about models not reality...you can not tell me that say gravitational lensing could not be described by an entirely different model and you can bet that one day it will be a different model, subject to all the rules of replacement of course.
I know the experiments and I cant argue against them but when the observation ( from galactic rotation curves) required so much more matter to make the sums work I dont buy it .. I say that is not unreasonable
.for whatever reason the sums may break down here..I bet they have...
Anyways this thread is not about General Relativity or gravity so forgive me for taking the thread away from the op.
I just enjoy all of it...
Thanks again.

) that gave rise to that speculation...I still agree with him actually. I know I know the photo the photo..it is still not of the black hole but when I see a picture of the actual black hole I will accept it is real.
