“The Universe Expands Beyond All Bounds”

The universe expands beyond all bounds, Black holes gain mass, where wonders surround. Curvature shifts like moonlight’s gleam, Adding new mass, no matter redeemed.

A new year dawns with lessons to share, Physics reveals a truth so rare. The cosmos vast, profound, and wide, Marks 2025 with knowledge as our guide.

The first endeavor of this brand-new year, Explains black hole growth without drawing near. Expanding space, a force untamed, Curvature energy, its role proclaimed.

Based on observed and verified research: arxiv.org/abs/2302.

Through our novel gravitational field theory: dx.doi.org/10.1016/j.astropartphys.2024.

Details await within the links above, Happy New Year 2025 to all with love! http://dx.doi.org/10.13140/RG.2.2.18170.


Observations have found black holes spanning ten orders of magnitude in mass across most of cosmic history. The Kerr black hole solution is however provisional as its behavior at infinity is incompatible with an expanding universe. Black hole models with realistic behavior at infinity predict that the gravitating mass of a black hole can increase with the expansion of the universe independently of accretion or mergers, in a manner that depends on the black hole’s interior solution. We test this prediction by considering the growth of supermassive black holes in elliptical galaxies over $0z\lesssim2.5$. We find evidence for cosmologically coupled mass growth among these black holes, with zero cosmological coupling excluded at 99.98% confidence.
