Dark Energy Decoded

The value of the cosmological constant obtained according to the quantum field theory is 10120 times larger than the observed small value of the cosmological constant. Such huge discrepancy with the cosmological constant, known as the cosmological constant problem would cause a vacuum catastrophe. Since the discrepancy involved with the cosmological constant is unimaginably very high, therefore, molecular diffusion model has been introduced in this paper as an alternative to dark energy in order to explain the accelerated expansion of the Universe. The molecular diffusion model considers the distribution of large-scale structures as molecules inside a vacuum chamber. Since large-scale structures are ensemble of atoms, therefore, they can be treated as distribution of molecules possessing finite amount of energy. Instead of considering that space is expanding, the manuscript emphasizes upon the recession of large-scale structures upon a stationary space-time continuum. Since the discrepancy with the cosmological constant is very large, therefore, instead of considering that empty space possesses energy, it would be much more prudent to consider that large-scale structures possess energy by the virtue of which they recede, quite similar to a molecule that recedes by the virtue of energy that it possesses, after all, “the diffusion or free expansion of gas molecules inside a vacuum chamber by the virtue of vacuum energy or dark energy” has never been heard of; such claim, if true, would only suggest that gas molecules do not possess any energy. The study shows that large-scale structures will attain a constant recessional velocity in distant future
