Einstein–Lemaître Model

The Einstein–Lemaître model is a cosmological solution describing an expanding universe, combining Einstein's theory of gravity with observations made by Georges Lemaître. It shows that space itself is stretching over time, causing galaxies to move away from each other. This model incorporates a uniform distribution of matter and energy, and it predicts that the universe has been expanding since the Big Bang. It helped confirm that the universe is dynamic and evolving, laying the groundwork for modern cosmology and our understanding that the universe is expanding rather than static.
