SCIENTISTS
you have 3 years.
Now they have -8 years.
Doc Brown actually went back and caused this invention to cease to exist, along with self-lacing shoes, the food hydrator, and the Mr. Fusion, in order to divert the timeline away from a looming nuclear apocalypse in the year 2045.
This is a thing that really happened… in a short released with the 30th Anniversary Blu-Ray box set.

Room temp superconductors were recently in the news, although I don’t think they’ve made wire out of the material yet.
But quantum locking would keep the board on rails, and would not allow the rider to deviate from the path. Still cool, but not a hoverboard.
We also have hoverboards, but they are large, use thrust engines or propellers, and are horribly inefficient.
*Potential room temp superconductors that still require confirmation
ftfy. This is one of the “holy grails” in science, and there have been many claims to have achieved it that all turned out to be false under further investigation. Definitely take the most recent claims with a really big grain of salt, pending independent verification by other labs. Remember: if it can’t be independent reproduced, it isn’t meaningful.
Full disclosure, I didn’t read the article on the superconductors. I assumed it was another one of those “Oh, neat” scientific discoveries that wasn’t as exciting as journalists want it to be. I’d love to see it when it’s real, though.
If confirmed, it would be much more than an “oh, neat” kind of discovery. Unlike many things which are very much a scientific pursuit – still worth researching, but having few, if any, applications outside of the pursuit of knowledge – a room temperature, ambient pressure superconductor has immense practical benefits. A true room temperature, ambient pressure superconductor would stand to revolutionize many things, and whoever discovers it will almost definitely get a well-deserved Nobel prize for their effort.
To be fair, we can still invent the hoverboard by 2015.
We just need to invent a time machine to go along with it.

Heck yeah!
Didn’t hacksmith on YouTube actually make one?
physics matters.
no it doesn’t
Omg is a fucking joke, why are people taking these so seriously?? 😂
We went from the first ever flight in 1903, to putting a man on the moon in 1969. I don’t know at what point the advances stopped, but I guess people thought they’d just keep going
What? In our lives we have decoded the entire human genome. Half a million people live today that wouldn’t if cancer research stopped.
The internet was created and literally connected the entire world and almost all its knowledge together.
You have a computer in your pocket that would have been the size of Texas 4 decades ago – Transistor tech growth alone is absolutely remarkable.
Now, GPT4/AI has made it so ANY human with an internet connection can have access to a world class tutor on any subject. Think about the 150 million Indians that live below the UN poverty line and the opportunities that provides them and thus enriches the world’s potential outputs.
If you want a read on how the world isn’t actually getting as bad we as all read about, in totality, (I think our western institutions being corrupted and dying is another story), read this book – https://www.amazon.com/Enlightenment-Now-Science-Humanism-Progress/dp/0525427570
While accurate, if feels disingenuous to frame it like this. Don’t misunderstand me, I’m not disputing the rapid increase in technology following the industrial revolution, but there were many incremental advances over the centuries before that led to those moments. We didn’t just begin to do things in the air in the 1900s.
As early as 969 or as late as 1264 rocketry was used to propel things through the air.
The dating of the invention of the first rocket, otherwise known as the gunpowder propelled fire arrow, is disputed. The History of Song attributes the invention to two different people at different times, Feng Zhisheng in 969 and Tang Fu in 1000. However Joseph Needham argues that rockets could not have existed before the 12th century, since the gunpowder formulas listed in the Wujing Zongyao are not suitable as rocket propellant.
Rockets may have been used as early as 1232, when reports appeared describing fire arrows and ‘iron pots’ that could be heard for 5 leagues (25 km, or 15 miles) when they exploded upon impact, causing devastation for a radius of 600 meters (2,000 feet), apparently due to shrapnel. A “flying fire-lance” that had re-usable barrels was also mentioned to have been used by the Jin dynasty (1115–1234). Rockets are recorded to have been used by the Song navy in a military exercise dated to 1245. Internal-combustion rocket propulsion is mentioned in a reference to 1264, recording that the ‘ground-rat,’ a type of firework, had frightened the Empress-Mother Gongsheng at a feast held in her honor by her son the Emperor Lizong.
In 1783 we were able to manage what I would call air travel. Flight is a bit of a loaded term but I think most would agree that this is flight despite being lighter than air.
The first untethered manned hot air balloon flight was performed by Jean-François Pilâtre de Rozier and François Laurent d’Arlandes on November 21, 1783, in Paris, France
In 1849 a heavier than air glider was invented. Pinning this down seems tricky. There are multiple accounts of folks earlier doing it. I think the problem is where do you draw the line between jumping while holding “wings” and actually gliding. Regardless, this predates 1903.
The first heavier-than-air (i.e. non-balloon) man-carrying aircraft that were based on published scientific principles were Sir George Cayley’s series of gliders which achieved brief wing-borne hops from around 1849.
Framing it as flight in 1903 to the moon in 1969 ignores a significant chunk of the histories of both air travel and rocketry.
This has always been functionally impossible at the current understanding of science, even with superconductors. There’s nothing to “push off of”, unless you can invent literal anti-gravity technology, which afaik, is impossible.
Sure, the Earth has a magnetic field, but it can barely move a compass needle. It can’t even lift a single gram of weight, much less some dude and a board.
You need a rocket in the bottom to be able to fly around freely. Or you’d be limited to keeping it inside a special area made just for it, using electromagnets.
Just replace all roads, sidewalks, and building interior floors with magnets. Easy.
Well, they did verify that there have been UFOS of nonhuman origin, and the Air Force verified those videos of “impossible movement” from said nonhuman crafts are real. So it’s entirely possible our understanding of physics is severely lacking. And this part is less verified, but there have been untold accounts of UFO sightings where there is no sound of combustion. So who knows
verify

Our understanding of physics is well understood to be severely lacking, this is why we’ve been searching for things like a Unified Theory for a solid century now. Because we haven’t found it yet. This does not require UFOs at all. It’s the reason we invest billions, not millions, into gigantic atom smashers and fancy-ass space telescopes.
Also, any UFO could potentially have access to a whole shitload of different maybe-possible propulsion mechanisms. They don’t need anti-gravity, people just like that one because it sounds cool. It’s more likely they’d be creating their own gravity, maybe keeping around a big blob of dark matter or something. Who knows? Lots of possibilities.
