This is pretty much a waste of time. None of that is anything I havent heard many times before and they explain things in such a dubious manner that I think it gives science such a sheen of fairytale dusted glossiness that the general public who doesnt take any real interest in this stuff is going to get a twisted unrealistic sense of what scientists who actually accomplish something do.
And then there is this they spend half of the show telling us that we dont understand space and time and barely spend any time explaining why they would say that and what is actually true. They do get around to telling us that movement affects time and what appears to happen far away is, in a spacetime sense, not what we would expect. Then, they set up the perfect example faraway galaxies moving at high speed away from us. But by the time they get to that all they can tell us is that space is expanding, things are pulling apart and we are seeing into the past when we see the light of distant stars and not a single word of the counterintuitive spacetime that they talked about in the beginning of the show. I would have thought they would explain that something nonobvious was happening and how we should really interpret the movements of distant galaxies, but no. They just end the show. Its the same glossed over hypy pap that they throw out every time.

You make scientists look like time wasting dreamers here. Everything was drama and cinematics.
Time. We waste it, save it, kill it, make it. The world runs on it. Yet ask physicists what time actually is, and the answer might shock you: They have no idea.
Even more surprising, the deep sense we have of time passing from present to past may be nothing more than an illusion. How can our understanding of something so familiar be so wrong?
In search of answers, Brian Greene takes us on the ultimate time-traveling adventure, hurtling 50 years into the future before stepping into a wormhole to travel back to the past. Along the way, he will reveal a new way of thinking about time in which moments past, present, and future—from the reign of T. rex to the birth of your great-great-grandchildren—exist all at once.
This journey will bring us all the way back to the Big Bang, where physicists think the ultimate secrets of time may be hidden. You'll never look at your wristwatch the same way again.
