Dark Energy …..Really
Dark energy makes up approximately two thirds of our universe. However, dark energy has never been detected, let alone measured. In fact, the term 'dark energy' can more accurately be described as simply a placeholder for something we do not understand. Cosmologists need dark energy to have something to refer to, when describing the apparent 'force' that is causing the accelerating expansion of the universe.
So, is there an alternative structure for our universe that could explain the accelerating expansion without the need of dark energy? There might be.... well, kind of.
If the universe had a super massive black hole that carried, say, two thirds of the mass of the universe, one could argue that all matter would migrate towards such an object simply under the influence of gravity. The only problem is that our seemingly flat universe is founded upon the universe being homogeneous. Such large objects are simply not allowed. However, if the universe was not actually flat but rather came back on itself, like the surface of a sphere, could such a massive object exist. Under the model of a positively curved spherical universe, this super massive black hole carrying two thirds of the universe's mass would be, by definition, located on that spherical surface. If we were on the opposite side of that sphere, all mater would appear to be accelerating away from us towards the '2/3rds' black hole. But would we have to be at the exact 'opposite' side of the universe (i.e. the 'antipode' of the the spherical model) for us to observe everything accelerating away from us? Not necessarily. If we were near, but not exactly at, the antipode of the '2/3rds' black hole, then we would expect to observe a slightly younger universe in one direction compared to observing 180° in the opposite direction. We would also see some of the other anomalies that are described on the Anomaly page of this website.
