Wrong conclusions that masses are attracted to other masses. They are not.
Remember that all of the universe is empty space. There is nothing else but a Tiny few millionths of 1% space which moves. This energy has enabled everything we see and feel as solid. Trillions of individual particles are made from the colliding random motion of space made to spin forever, this spin is a pull on space making streams of space head to each existing particle. This is what we know as gravity, an eternal force increasing by addition.  Huge amounts of masses produce everything including forces eventually,  mainly from spin or circular motion.   Streams of space not dark matter or dark energy.
Massless light going with the flow, which is always flowing.  Redshift of distant light shows greater and greater travel against the space streaming from its origin.
