The Big Bang Theory is supported by the observation of red shift of galaxies outside our own, that every galaxy appears to be moving away from the observer
What is expansion?

Tiltmeters detect very small changes in the slope (tilt) of the Earth's surface. These changes result from the upward movement of magma beneath Earth's surface. These events can be predicted by monitoring tiltmeters
