I look into the 'past' when i look at my keyboard... looking at far away objects is just a more exaggerated example of special relativity. Information travels at a finite speed. It takes time for light to get to our eyes from wherever it came from. We don't see the 'present' it just seems like that because the distances are much smaller in our everyday lives than in relativistic forays. To see future 'alternatives' all one has to do is make a prediction about something. Quantum mechanics uses probability all the time. There is no way to 'see' the future, all we see is the past.
