I saw this the other week and have not been able to stop thinking about how crazy it is that scientists are now able to mask-time. although i am far from possessing any meaningful scientific knowledge, as a common lay person it makes me wonder about the whole time travel paradox, how soon this will be feasible considering the rate at which technology is advancing and what would the experience of time be like for the observer vs. the observee? oy vey, I think my eyes just crossed.
