Is time travel possible? Theoretical physicist and 2057 host Michio Kaku explores the possibilities.anything about of travel video .
I have a long opinion on this, here's the short version. 
Around 1250AD there was a shift in human consciousness relative to our orientation with space. This is evident in art and in some poetry, and seems to mark the beginning of the Renaissance era in the Western world. Art prior to that time (e.g. Byzantine, Egyptian etc.) reveals that it was rather two dimensional. Around 1250 we see evidence of the first Italian and Dutch artists who begin to explore perspective. They were objectifying space in a way not done before in art, illustrating three dimensions and incorporating light and shadow. There were some rather bizarre works produced for the first 100 years or so as the artist struggled with the concept of perspective. By around 1350 few people were painting two dimensional art. Also around this time Euclidean geometry started to give way to more rational explanations of space and properties of the three dimensions. By the 16th century the scientific enlightenment era was in full swing, with Da Vinci placing the capstone on both art and science with his explanations of perspective and many of the scientific principles of reductionism we recognize today. The trade-off with this development (i.e., objectification of space) has reached a critical junction in our times. The attending benefits of our new found understanding of space, and all the wonderful technology goodies scientific rationalism has brought as a result, took us a step or two away from our innate knowledge of belonging to a greater whole within nature (I hear your groans). Perhaps an honest evaluation of world civilization today would recognize that we are quite insane; we can fly to the moon which is way cool, but we can also destroy ourselves in very novel ways - which isn't cool.
Fast forward to 20th century: The artist and writer, since the beginning of the 20th century, has been showing us that our current existential dilemma is time. While our full understanding of spacial perspective may only be at about 50%, the modern problem is really time. We don't have enough of it, we waste it, it fly's by quickly etc. etc. etc. Beginning with Picazzo, Braque and a few others we started to see the incorporation of time into the dimension of spacial perspective. We have countless examples of sculpture that also reflect the artist wresting with this new awareness. Many decades later people are struggling to interpret what they see in this art. Perhaps unconsciously we recognize the art states something significant, but we don't know what that significance is yet. Also around the beginning of the 20th century scientific principles were up-ended with Einstein's theories of space, time and gravity and Freud's and James' introduction of the psychological principles of perception (coincidentally). Beginning at mid-century we saw the writing craft of science fiction elevated to new status. Conquering space brought from imagination the idea of worm holes, while conquering time brought the idea of the warp engine so we could move at light speed. The problem here, IMO, is that space and time travel as we currently think of it is premised on reductionist concepts born in the era we may be now exiting after 800 years. Like those looking in confusion at a Picazzo painting, we may need to shift our perception of time so that it can travel through us.
Summary: I think we will master time travel, but in surprising ways.
