More evidence that the universe is a hologram

We test a class of holographic models for the very early Universe against cosmological observations and find that they are competitive to the standard cold dark matter model with a cosmological constant (?CDM) of cosmology. These models are based on three-dimensional perturbative superrenormalizable quantum field theory (QFT), and, while they predict a different power spectrum from the standard power law used in ?CDM, they still provide an excellent fit to the data (within their regime of validity). By comparing the Bayesian evidence for the models, we find that ?CDM does a better job globally, while the holographic models provide a (marginally) better fit to the data without very low multipoles (i.e., l?30), where the QFT becomes nonperturbative. Observations can be used to exclude some QFT models, while we also find models satisfying all phenomenological constraints: The data rule out the dual theory being a Yang-Mills theory coupled to fermions only but allow for a Yang-Mills theory coupled to nonminimal scalars with quartic interactions. Lattice simulations of 3D QFTs can provide nonperturbative predictions for large-angle statistics of the cosmic microwave background and potentially explain its apparent anomalies.

I started reading that but the big words like early made it tough.

Hey. My neighbor is in cosmetology school also. Neat

Well duh. Ever walk into a room and instantly forget what you went in there to do?
Simply the being in charge of you in the sim changed your action queue. Just like we do in the sims games

Makes complete sense. Thanks for the post.

The person that wrote this dumb shite should apply for a job cleaning windows with their fricking tongue.

Actually... when you walk into a room and instantly forget what you went in there to do... that means one of the Men in Black characters erased your memory.

Nuh uh. The men in black stay and tell you what you were doing/are about to go do.
