This is why the Delorean needs to reach 88 MPH in order to engage the flux capacitor and send Marty back in time. It is the minimum speed needed to temporarily lift the pressure imposed on the spacetime continuum that keeps us affixed to the surface of the Earth at the bottom of this 4,000-mile-deep gravity well in which we are all living*.

*except for the 3 people currently on the ISS.

Not much of an "explanation" but merely stating it so.
