Has physicist's gravity theory solved 'impossible' dark energy riddle?
Prof Claudia de Rham’s ‘massive gravity’ theory could explain why universe expansion is accelerating - Guardian 25th January 2020.
Cosmologists don’t enter their profession to tackle the easy questions, but there is one paradox that has reached staggering proportions.
Since the big bang, the universe has been expanding, but the known laws of physics suggest that the inward tug of gravity should be slowing down this expansion. In reality, though, the universe is ballooning at an accelerating rate.
Scientists have come up with a name – dark energy – for the mysterious agent that is allowing the cosmos to expand so rapidly and which is estimated to account for 70% of the contents of the universe. But ultimately nobody knows what the stuff actually is.
“It’s the big elephant in the room,” says Prof Claudia de Rham, a theoretical physicist at Imperial College. “It’s very frustrating.” - GUARDIAN
The Guardian reports that Professor de Rham is theorising about "Massive Gravity". This proposes that gravity /gravitons / gravity waves have mass and are slowed or accelerated by the medium they travel through. Apparently, this novel concept mathematically explains Dark Energy, which theoretically drives the ever accelerating expansion of the observable universe. I prefer my idea that light /photons/ wavicles have slight mass which explains gravity.
Gravity is the relative absence or reduction of the pressure of the radiation that fills the universal ocean of radiation, which is from 13.7 to 43.7 billion-light-years deep. Contemplate "The ever tightening knot of gravity, ultimately resulting in black-holes" and "Counter-intuitively, the centre of the Sun is very dark" because the centre is most "shaded" or protected from or excludes the universal radiation. (NB between masses as per Casimir). The external radiation is the PUSH and the internal partial absence of radiation is the PULL of gravity. NCH March 2015 e-mail noel@noelhodson.com
The radiation of the observable universe, comprises all wavelengths of radiation - or light. in matter, where a shadow is cast, some wavelengths are excluded. The universal external pressure is greater than the internal pressure, the precipitated matter coalesces, a gravitational object forms. The force or energy of gravity emerges.
