Click For Summary
Gravity is fundamentally an attractive force, contrary to some claims suggesting it can repel. Theoretical concepts like negative matter or dark energy might imply repulsion, but gravity is rooted in the characteristics of space-time rather than being an inherent property of matter. Discussions highlight that while gravity appears to have repulsive effects in certain orbital dynamics, such as with Pluto and Neptune, these are due to gravitational interactions rather than true repulsion. The notion of gravity as a push force has been largely discredited, with experimental evidence supporting its attractive nature. Overall, the conversation emphasizes the need for clear definitions and experimental validation in understanding gravitational forces.

If you feel mine is a speculation and its unfounded,look for the book, Physics for Scientist and Engineers by Paul A. Tipler and read on the chapter, evolution of the universe and about the lepton era. Be good guy
Why? Does it introduce observational evidence that the rest of the world is unaware of, that supports the proposed theory?

Or is it just postulating a speculation that is not founded upon evidence?

lets not forget the theory of gravitons.
for those who don't know some scientist's believe that there are particles no charge, no mass, and carry energy/gravitational energy, this is almost identical to photons, particles that have no mass or charge but they carry electromagnetic energy,
