There is no such thing in our universe as nothingness. For example even the vacuum of space in not nothingness. Einstein predicted in his General Theory of Relativity that the is no such thing as gravity as a force pulling things. What we call gravity is actually a distortion or warping of spacetime caused by the presence of matter or energy. A massive object generates a gravitational field by warping the geometry of the surrounding spacetime — where spacetime is what you are referring to nothingness.
All of Einsteins predictions that we found a way to verify (sometime it took a long time to verify some of them), have turned out to be true.
For example the Webb telescope just "took a picture" of what is know as the Einstein Ring

He predicted that if there was a star directly behind another star (the stars in this case are billions of light year part) that the closest star would warp space (what some incorrectly call gravitational pull) such that the mass-less photos of light will appear to bend around it because the warped space is the shortest path for the light to go. Newtons theory incorrectly would have the light from the furthest star blocked by the closest one because he assumed that light travels in a straight line (straight from the point of view of nothingness)
It took over a hundred years and a wonderful new telescope recently placed in a parallel (concentric orbit with earth around the sun) orbit with earth to verify that Einstein's prediction of light being bent thru spacetime warped into what appears to be a ring.
Yeah the Webb telescope cost $10 Billion that I guess some here would say could better be spent by buying a lifetime of high end escorts for every UG'er for the rest of their lives but I find it exciting to be alive with all this happening.
BY the way, besides being a genius, Einstein was as a very horney guy.
