Can you bridge from Polygon to base?

Excuse me, could you please clarify if it's possible to establish a bridge or connection from Polygon, the popular Ethereum scaling solution, to the base or main Ethereum network? I'm curious about the technical feasibility and potential challenges involved in facilitating such a transfer of funds or assets between the two platforms. Could you elaborate on the process, any specific tools or protocols required, and whether there are any associated costs or limitations I should be aware of?
