Albert Einstein predicted the existence of gravitational waves in 1916 in his general theory of relativity.
The first proof of their existence didn't arrive until 1974, 20 years after his death.
You realise if we're a simulation, our existence could very well be an architectural representation of a conclusion. 🙃
116 years after the Special Theory and 106 years after the General Theory and observations continue to land regularly confirming that these models provide the best insight so far into the Universe at its macro scale, quantum mechanics being a whole 'nuther thing and perhaps intrinsically so. It's almost guaranteed that another more subtle and detailed model of the Universe will emerge, maybe yet this century or not for a millennium or two. Either way as I'm almost 70 GR will likely be the best model I'll ever hear about! The leap from Newton's static space and time and instantaneous force gravitation to the relativity Universe is still a feat of imagination that I find astonishing.
Who said we're a copy? More like an imagination. I couldn't get the blue pill down so I had to settle for the Big Red One.
I suspect this. I have been watching and we keep seeing data that does not fit the standard models. Something will have to give.

I still can't get my head around the apparent fact the Moon rotates on it's axis. I've watched every animation on the net and I just cannot see it. 
For example... say a sattelite is revolving around a body "always facing north"(for all intents and purposes). This would appear to be rotating on an axis, no? However if it is "always facing toward the body", how is it rotating on an axis? Is it now not "fixed" in it's position?
I done ged it.
Where's the emoji with the shrugging shoulders??? SHEESH!

The moon orbits the Earth every 28 days and the same hemisphere of the moon always faces the Earth. If you (mentally) hover a million miles above the Earth and watch the orbit you will see that the moon must rotate on its axis one revolution each month in order to keep the same hemisphere facing the Earth. If it didn't rotate we would see the entire surface of the moon as it orbited the Earth rather than just one hemisphere.
I am somehow fond to Roger Penrose -Hameroff ORCHOR theory where they basicly say that maybe the only fundament of universe is to preserve its mathematics and maybe the whole universe is a memorizing game where it practices its own rules in every possible way changing them from time to time.They say the first millisecond after bigbang we had different laws than the next millisecond or something in this line...The formation of life , bodies, cells organisms looks like preserving dna as a possibility of mathematical combination of rules and this theory has emerged that the only purpose of a body is to protect its nervous system which is protecting the integrity of dna which is protecting the preservation of accumulated information about itself and while fighting enthropy it discovers new combinations but more interesting is that while lions are looking at preserving the most powerful killing machines through natural sellection people preffer to do away with the natural advantages in favour of preserving better suited brains for the future .So the conscience looks like the ultimate secret of our universe because all the rules of the universe led to a conscience formation that's looking to devellop itself into a better conscience .Now this conscience is looking upon itself and the universe and chose develloping AI seeing its own limitations which will not be bound to human senses.What this AI will eventually choose to do further with its newly aquired knowledge is a true mistery to which humans might never be in sync, but it looks like the only way to defeat or avoid enthropy in larger and larger circles . Now where's the gravitational waves and Einstein in this? It's just somewhere on the path of evolving a conscience able to build a quantum computer that will be able to to a faster research of its own principles of operation so the whole universe is looking through our conscience like through a mirror getting the opportunity of a better mirror when AI will take lead.Humans aren't the Gate keepers of the last frontier.We are still tightly linked to our senses and fears as the dynosaurs or the lions...We can hardly preserve ourselves while loosing all sorts of bits along the way with the only goal in mind to make a better brain than Einstein's... I for one am envious on birds...I don't give a f...k literally on gravitational fields and my best possible accomplisment while still alive would be to grow gills and wings to see and feel what the birds and fish see...I'm not much different than archeopterix in aspirations, goals and wishes...
I can bet that Einstein was really happy to flea natzi Germany and enjoyed the flight over Atlantic a lot...not sure if he got in the USA by plane though...

Check the picture. The Moon (M) has a line in it - the end where it meets it surface is a fix point on the moon - you could stand there. Now, if the moon was to circle around Earth.. ooops it does 🙂 - what would you see of Earth as the moon takes a trip around Earth in the different M positions 1-5? This is all seen as per from the "above" i.e. looking down on E and M.
So you dont see E from pos 2 & 3 and barely from 4.
But imagine you would turn the moon so that that line in M was always pointing to the centre of E you would see E all the time. And that is what going on - M slowy rotates around its own axis to do just that. From E, it looks like M stands still i.e. not rotating. Hence, we never see the DSOM - call Pink Floyd if you don't believe it 😉

Thereby hangs a tale!
Einstein first moved to Belgium from where, in 1933, he discreetly departed and sailed across the English Channel to settle in the depths of the English countryside.
He stayed in a little log cabin near Cromer where, when it was reported there was a price on his head, he was protected by an armed guard of men.
In October of that year he left by boat for America and was never to return to Europe.

Thanks! I was never too interested in his life...Once I learned in high school that his relativity theorem was 99% Maxwell's work who died at just 42 years old and never got the chance to finish it I stopped being interested in what a marvelous patent pending creature Einstein was...I remember reading an article telling that he refused to share the Nobel prize with his wife at the time the work was done who helped him a lot with the calculations....and conveniently for him pledged that the money should be used for their retarded child alone...A lot of people with much lower IQ than Einstein's realized that genius and retard are the two faces of same quantum coin...it's just another genius that we wait to name that coin.
It's a fact that Einstein was inspired by Scottish physicist, James Clerk Maxwell.
When asked if he stood on the shoulders of Newton, Einstein replied "No, on the shoulders of Maxwell."
It was in the context of Maxwell's electrodynamics that Einstein first considered the principle of special relativity.
