I suppose I should watch that clip, it's been decades since I've seen The Time Machine, but it seems if physical dimensions are going to change over time, it's going to take like a billion years for it to change enough to notice. I'm sure the budget for that movie wasn't big enough to go that far back or forward in time. <joking, sorta>
A more plausible scenario in the movie, and envisaged some 20 years before the coming of the compact disc, was the 'talking ring'.
It was enough to put Rod Taylor's head in a spin!
P.S. The Time Machine won an Academy Award for special effects for its time-lapse photography depicting the world changing quickly as time passes by.

Now it's getting hard to distinguish fact and fiction.

At least "metamaterial" technology is a fact, and is used in other areas of research.
The metamaterial below has a tubular structure that helps ultrasound to penetrate bone and not just soft tissue.
The metamaterial in rayma's link, not surprisingly, doesn't actually turn back time!
As I interpret the article, the metamaterial can tweak the speed of light passing though it in order to double or half its transit time.
This manipulation technique is known as the 'velocity modulation of electromagnetic waves': https://ieeexplore.ieee.org/document/1124533
Interesting, but the physics is much more complicated than the mere game of Ping-Pong referred to in the article!
Yea, nice clickbait heading!
You'd think a publication as august as Scientific American would be above that.

As a Physicist and Mathematician, I admire Richard Feynman:
He made me and Lenny feel Smart! Not smarter than he was, of course.
Mine own IQ is about 128.
Not sure where I am going on this:
But enjoy. 🙂

A one hour 15 minute long video?
I'll put it on the back burner for now!
I suspect there will be mention of the conservation of CPT symmetry.

Indeed there was a mention of CPT Conservation aka Symmetry!
Was it just me, as an autistic person, or did this Forum suffer an Outage yesterday?
Caused me considerable troubles. And I am good at hacking Computers:

There is so much bollocks in the promotion of science papers these days. They’ve borrowed techniques from the tabloid press as they all try to get airtime or exposure of some sort.
The whole thing about Feynman’s low IQ I believe stemmed from a comment made by Gel-Mann who said he ‘spoke like a bum’. I don’t put much store in IQ beyond a certain point and my psychologist wife has explained to me a few times why they are deeply flawed.
It seems being obsessively enquiring about a subject over many years counts for much more, and the earlier one starts the better. If you spend your youth smoking pot, drinking and carousing, you’re unlikely to ever make it to genius level.
(Gel-Mann was famously arrogant: ‘if I have seen further than most, it’s because I’ve been surrounded by midgets’ which was him channeling Isaac Newton).

We've got a good few like that around here! But5 when I travel to the Far North there are vast numbers. And as for the Western Isles
they are the whole population.
Indeed. Unfortunately it's the system around them - you have to publish, get attention, to get any hope of funding. Sadly some of the heydays of science where when research was funded for it's own sake, not on the basis of published papers or having to convince someone it will make a return on investment in a couple of years. Blue sky research is no longer funded, sadly.
🤣🤣🤣🤣We've got a good few like that around here! But5 when I travel to the Far North there are vast numbers. And as for the Western Isles

Yes. I also wondered if it was just me, However a link popped up to some service the forum uses when it timed out. That said yep, a problem try again in a few min. More like hours.
The outage gave me the opportunity to get stuck into Bill Bryson's "laugh-out-loud" book on growing up in 1950s America.
Not so amusing was his observation that:
"Altogether, between 1946 and 1962, the United States detonated just over a thousand nuclear warheads, including some three hundred in the open air, hurling numberless tons of radioactive dust into the atmosphere. The USSR, China, Britain and France detonated scores more."
Children, with their love of milk, were positively aglow with strontium 90 - the chief radioactive product of fallout!
Sheer Madness. 😱
No wonder the fictional alien Klaatu came to Earth during the Cold War with an ultimatum.
"Klaatu barada nikto." Remember those words!
Strontium is a beautiful place...
The small hotel in the 2nd pic. is just up the road...very comfortable and excellent food.
Good base for Morlock hunting but the Strontium river is not much cop for Salmon.
The hotel started life as a Military Barracks back when it was thought elsewhere that Scotland needed taming!

A 'charming' man who introduced the concept of 'strangeness'! 😀
