Standard cosmology has hallucinated 68% of the universe because it refuses to accept a simpler truth.
'Dark Energy' is not a physical force. It is the mathematical placeholder for your failure to account for gravitational time dilation in cosmic voids.
The universe isn't accelerating its expansion; you are simply watching time run faster in the emptiness between structures. Complexity is the mask we wear when we lack the courage to admit our foundations are wrong.
The truth is always simpler than the lie used to maintain the status quo.
