The MEDE model treats dark energy not as an eternal force, but as a temporary tailwind: it emerged when the Universe was half its age, and will gradually fade away, explaining puzzling fluctuations in its behavior.

Dark energy is not a perpetual cosmic engine. The new model allows it to emerge, accelerate expansion, and one day vanish, like a ghostly tailwind.

🎯 If the model is correct, in the distant future dark energy will disappear, and the expansion of space will continue only due to the accumulated momentum.
