Anyway, when something happens, it can't ever "un-happen", and that's a fact that persists indefinitely. And that's why time travel is impossible. And that's the point of the video.
used data from the particle physics experiment BaBar (pictured right, at the SLAC National Accelerator Laboratory in Menlo Park, California) to make the first direct measurement confirming that time does not run the same forwards as backwards — at least for the B mesons that the experiment produced during its heyday. The application of quantum mechanics to fundamental particles rests on a symmetry known as CPT, for charge-parity-time, which states that fundamental processes remain unchanged when particles are replaced by their antimatter counterparts (C), left and right are reversed (P) and time runs in the reverse direction (T). Violations of C and P alone were first seen in radioactive decays in the 1950s, and BaBar was used to confirm violations of CP in B meson decays in 2001. To keep CPT intact, that implies that time reversal is also violated, but finding ways to compare processes running forwards and backwards in time has proven tricky.

If parallel universes/realities exist then we it is still possible for time travel to occur. To be honest after watching your video and reading what you typed I only have the slightest clue of what you're talking about.

The following is my opinion as a member participating in this discussion.
I think you sort of have to be at least familiar with the work that's preceded this to appreciate it. Out of context, it can seem a bit disjointed. But if you are motivated enough to look back at the history for this member, this contribution is a highly creative (IMO) and evocative example of one of the points he's been trying to make.
When I first saw the thread title, I immediately thought about Pirsig's 'Zen and the Art of Motorcycle Maintenance' (which I highly recommend for anyone who hasn't read it).
Different strokes, guys. I thought it was entertaining and creative. Flag from me.
As an ATS Staff Member, I will not moderate in threads such as this where I have participated as a member.

I loved it. It's not often you hear philosophical matters discussed in song. You remind me of Zappa for some reason. Well done.
As for time travel? I always wonder how people could hope to travel to a place (or time) that doesn't exist. Even 'now' as a unit, a state or an idea, like all ideas, is entirely fleeting. Maybe we should learn to travel there before we attempt to travel anywhere else.

I get what your trying to get across, but if you don't mind I'd like to play with it just a bit. Whether you go with the idea that this universe is a hologram, or that we are made of quantum intangible stuff that somehow became tangible, we can't escape the fact that, more and more, science is telling us that this solid, physical existence isn't real. We're waves, no we're particles, no we're waves....
That said, I'd like to compare this existence to the dreams and thoughts that we conjure up. In your mind, please create a man in a black tuxedo and smoking a cigarette while standing in a white room. Remember his white skin, his dazzling smile, his neatly cut hair. Remember this man well enough to make him a memory for you.
Now, clear the man from your mind (think anything else: birds flying, a football game, anything).
Now, please call up the memory of the man in the black tuxedo smoking a cigarette in a white room. You didn't RE-create this man. What you did was you searched your mind for where this man resides in your memory. Now, please change his black tuxedo for a white one, and make the white room a black room.
My question is, did you go back in time to alter this man's appearance? When you conjured him up from your memory, were the chemicals in your brain the exact same chemicals used to create this memory in the first place? If they are the same chemicals then the only thing that changed is time. You went BACK to a memory and changed it.
Hope I explained this well enough, though I seriously doubt it. Even I got lost near the end, but maybe you got the gist of it.

Totally Modern Beat.
Loved it, and followed it well I think,
but will enjoy viewing again (and Maybe again),
a lot was showcased in this montage argument of a fixed permanent Now.
Enjoyable and thought provoking to say the least.
I think I even saw a few clips of my favorite Twilight Zone or One Step Beyond shows.
Wonderful.
