    I know there are 4 forces
    Gravity,Electromagnetisim,Strong and Weak

    Does anyone know about any other forces, that they think are in the universe.

    The dark energy that causes the accelerated expansion of the universe might be considered a diffferent force, but if it is explained by the cosmological constant in Einstein's field equations, then it's just an aspect of gravity.

    I thought the cosmological constant was one of Einstein's biggest flops? At least that's what I remember reading in some book...

    Einstein introduced the cosmological constant for the wrong reason (he was trying to make his theory predict a steady-state universe). It seems there might a cosmological constant after all, but for an altogether different "reason," to explain the accelerating expansion of the universe.
