The Dark Side of Time

An interesting Video from the tube explains why the orbital speeds of stars, as you go farther out in the galaxy, do not decay with their distances from the center of the galaxy. What do you all say about their explanation?

4 threads? Was that necessary? Ok I see you got that straightened out. Thanks for the video i will check it out.

Clearly you didn't watch the video

Gotta get our attention right?

Peace

Ticking away the moments that make up a dull day.

Ooops Three Galaxies removed from the ether already! Just shows how nothing stays pristine forever..except forever!

You fritter and waste the hours in an offhand way....

Well...I watched 13 minutes of the video and I'm lost...The math and other gobledegook is way beyond my comprehension. It may however be good material for those who understand math and quantum physics to the nth. I just end up feeling uneducated. I'll give the thread a flag because of the video content which is relevant but way beyond my vocabulary.


ETA: the OP gets a star because maybe he understands!

Can you post a brief explanation of the video please [ my wifi is crap ]

Jumpin Jackfish that's funny. If there's a brief explanation I gotta see it. Can you describe the universe in a paragraph?

Well then...There may be hope

It started out like Einstein thought experiments.
Riding a light beam.
Elevator example for frames of reference.
Paradox twins.
Then it moved to a sort of entropy based Ether theory.

I'll watch this but I had to comment to say the replies so far have been hilarious.

If you're not back in 59:59...We'll know your brain exploded

Kicking around on a piece of ground in your home town....

Waiting for someone or something to show you the way.

I've watched it once. The math ain't so high or anything, but there is quite a bit of it. Its the new paradigm of looking into the future that intrigues me, though this video has to be watched more than once to fully grasp the whole subject and the sound quality is not so good

Lol your attention don't count at all

Tried watching some of the video, but it's a bit too sciency and math-y for me. Could anyone please distill the main ideas and conclusions in that video?

It's considered good forum etiquette to provide some explanation or description of the video's content (especially if it's close to 1 hr long!), rather than just plopping it down and hoping people will watch it in full and understand what is being said.

Thanks.

P.S. I opened the video in Youtube page, and the video description is a bit more helpful:

Most physics theories tend to have a unique premise in common: one time dimension. In fact, there is a growing consensus that time is just an illusion.

Yet, applying extra dimensions to time can successfully modify modern physics without violating the conservation laws long held to be true. Modern notions of quantum gravity and curved space-time can successfully be replaced with an infinitude of relative frames of reference, progressing and regressing though infinite series of relations, which imply the existence of multidimensional time.

Interesting, but hypothesising about different dimensions of time is like falling deeper and deeper into the rabbit hole.

P.P.S. Just took notice of the video's author and presenter - someone named Gavin Wince, and had a look around on Google on who or what he is.
cosmoquest.org...
scientopia.org...
He's a crackpot philosopher who has taken it upon himself to "fix" practically everything in maths and science.

I'll stick with genuine theoretical physicists, thank you.
