[SW] How can or how are a few Sith able to cause a massive shift in the Force? What exactly are they doing that causes a shift in the Force?

The exact mechanism by which they amplify the power of the dark side and upset the balance of the Force is unknown, and always has been.

Theories abound, but really? The Sith had been actively corrupting the Republic leadership for decades if not centuries in preparation for war, fostering hatred and anger and suffering everywhere they went. And now we know that in addition to that, the Sith had a shrine buried deep under the Jedi Temple on Coruscant, and Palpatine was using that shrine to basically deafen the Jedi to the Will of the Force, spreading its effects and corrupting the Temple above it.
