Semantic Time Travel, A Proposal

Time travel will exist in 20 years. Don't worry, the space time continuum will be fine. We won't alter our present. You won't have the opportunity to accidentally hit on your distant relatives. Unfortunately for Homer Simpson, it won't start raining doughnuts. In the comfort of our own homes, we'll travel to any date, time and location we have data on. Semantic Time Travel is coming, and it's going to change the way we experience history.
