"The stakes are high. If they detect the vortex, precisely as expected, it simply means that Einstein was right, again. But what if they don´t? There might be a flaw in Einstein´s theory, a tiny discrepancy that heralds a revolution in physics."

So what would the revolution be?

And if Einstein was right, did they just waste $millions$ to prove it?
