I asked ChatGPT what percentage of the universe is made up of Dark Energy. By the answer I received (which I included below) it sure seems to me that "reality", the one we live in, amounts to only 5% of the Universe.
The AI's answer...
According to the latest measurements and observations, it is estimated that about 68% of the total energy density in the observable universe is made up of dark energy. Dark energy is a mysterious force that appears to be causing the expansion of the universe to accelerate. The remaining 32% is made up of dark matter (27%) and ordinary matter (5%). However, it's important to note that these estimates are subject to revision as our understanding of the universe improves through new observations and measurements.
