THE BIG-BANG THEORY CONTRADICTS BOTH GENERAL AND SPECIAL RELATIVITY

The standard cosmoillogical model or Big Bang theory is entirely based on the notions of vacuum energy and space expansion- which are interlinked (the latter is caused by the first).
But at the same time is claimed to be based on general relativity, and also on special relativity. In reality, it flagrantly violates both.

In special relativity, energy is equivalent with mass.

If energy is equivalent with mass, how does a vacuum or empty space have any energy ?​

It can't ! Because E=mc^2, and vacuum has no mass, so it can't have any energy either ! The energy of vacuum is precisely ZERO according to SR ! In this theory, empty space or vacuum cannot contain any energy, since it contains no mass which can be equivalated with energy E=mc^2. How can anyone claim that vacuum has energy, without rejecting this equation and special relativity altogether ?

And even if vacuum had mass or energy, how does that energy expand space ?
In General Relativity space is curved by mass and energy, which is what causes gravity according to Einstein. Einstein never claimed that energy expands space, and actually he claimed that the universe should contract from gravity according to his theory, where space is curved by mass and energy ! Even if empty space had energy, it would simply curve and contract at a faster rate, and not expand, which is the exact opposite of contraction. It simply does not follow why a space that contains energy (and therefore mass) will expand, it is a non sequitur. And a clear contradiction of Einstein's theory, and of the notion of a vacuum itself. Because a vacuum which has energy or mass is not a vacuum, and is not an empty space at all.

So in order to claim that empty space has energy, you need to reject Special relativity. And in order to claim that this energy expands space, you need to reject General relativity. Big bang cosmologists claim both, so they reject both, while at the same time claiming that both are true and building their standard cosmoillogical model on them.

And then they wonder why cosmology is in a crysis ! Because their stupidity is truly infinite and it just never stops. In fact it accelerates at an ever increasing rate, just like the expansion of their big-bang universe.
