    Einstein was not sure if the universe was expanding, contracting or static. He famously had a constant he could use to change this:

    "…Einstein’s cosmological constant, is a coefficient that Albert Einstein initially added to his field equations of general relativity.

    Einstein introduced the constant in 1917 to counterbalance the effect of gravity and achieve a static universe, which was then assumed. Einstein’s cosmological constant was abandoned after Edwin Hubble confirmed that the universe was expanding."
