The bigger the picture you're looking at: the weaker gravity appears to be!

One begins by realizing that reality is made up of particles infinitesimally small. These in turn are constantly moving outwards, and at the same time building together under the aggregating force of gravity, to form bigger and bigger entities! This is the reason as to why we should not be surprised at constantly discovering a plethora of new particles - when we smash things together in accelerators - some of which we deem to possess what to us appears to be no mass!
Of course as these particles move outwards, the area of space in which they are actually in, gets bigger and bigger... hence the relative strength of gravity appears to weaken more and more. This is why the force which we notice at our atomic level, is only about (1 in 10 to the 40) at our much bigger planetary world! Naturally, as the universe expands and the particles tend to "agglutinate" to form bigger and bigger particles, the distances between these resulting bigger and bigger entities become greater and greater. You can test this yourself from what we currently know... planets in a system tend to be much closer than stars, and stars tend to be as a group much closer than galaxies. Likewise galaxies are grouped together in a much closer arrangement than clusters. The latter would also follow as you consider super-clusters or any other bigger entities on the increasing cosmic 'roller-coaster'.
In view of the foregoing, it should not surprise us at all, that light being received from massive distances away is more and more red-shifted, the further away the distance is. And it would make no sense to try and explain the latter, with the preposterous notion that the universe is accelerating outwards... when we have no idea as to what could cause such an acceleration!
Obviously then, it's a very tenable picture that the universe is expanding and that as a result of this expansion, the relative strength of gravity appears to weaken more and more, as one looks at a bigger and bigger picture! I hope that these thought-provoking developments of mine can solve many cosmological riddles with a very simple matter-of-fact approach.
Finally, although I began this article with the talk of infinitesimally small particles, one must not talk of infinity in such a way that it appears as if we've got the mastery of it all... let us remember that we cannot ever get to infinity; and I must finish off by saying that the concept of a "singularity" is a very silly and stupid notion .
