Future Definition and 789 Threads

It so hard to predict the future but are there any technologies from sci-fi movies or books that can’t happen in real life because it’s just completely impossible to create them? For now and even when we have more advanced science knowledge?

I was reading a Nature article by Dean Keith Simonton speaking about how science seems to have slowed and there really isn’t such a thing as a real genius anymore. He defines a true genius as “A real paradigm shifter. A Renaissance human who could completely change the way we understand the...

Apparently, among the options for the fate of the universe, the universe reaching heat death in the extremely far future is the most likely one, after the last black holes would have evaporated (https://en.wikipedia.org/wiki/Heat_death_of_the_universe) But, even if objects in extremely long...

I was watching a video on YouTube and while the channel is very credible; it said the often-believed-erroneous-belief that quantum entanglement can allow FTL travel or communication. I left a respectful comment saying that this is incorrect but many other people actually do believe QE is FTL...

I hope this is the right forum right now I’m a 2nd year physics student in the United States and I’m really interested in nuclear/plasma physics. The thing is that I know the U.S. has great national labs to do internships at and good graduate schools here but I’m also interested in studying...

im TR094, i like physics (particle and nuclear physics to be more specific). im at 8th grade right now (in finland grading system goes 1-9, 7-9 being high school). i get good grades at math and science but am weak to laungage. my dream place to work at is in los alamos national laboratory...

What kind of technology will be available in a million years from now? Is the world going to be a better place in a million years from today? Will it be possible to solve chess or have completely self-driving cars and self-driving trucks in a million years from now?

Suppose a stationary reference frame, any other reference frame will have a clock that advances at t'= t/gand is moving away at velocity v. g is the relativistic factor. we can write: C d t' = Cdt/g and d x = v dt this can be written (Cdt',Cdx)=(C/g,C v) dt ; since 1/g2+ v2 =...

I subscribe to this forum because I like science. I think science is the future and I don't know why but I think that time travel is possible with science. I looking article about this subject and this is amazing. I want to learning more about time travel and other science subjects. Thanks for...

How did you find PF?: Google Search In engineering, math, physics, and astronomy, which one has a fast development speed?

Dear Physics forum, Recently I read about iron star, the consequences of quantum tunneling. And I wonder of these things. Considering protons don't decay, and there's no big crunch and the universe expands normally (heck, I don't know what "normal" is) so there will be no big rip. So in the...

There has been an explosion of discussion among experts about the evolving/growing dangers of AI and what to do about it. This debate has gone public, largely due to the recent success of generative AI, and the rapid pace of improvement. As an example, AI models which can generate images based...

I am frequently contemplating the size of the universe. Logic tells me that existence cannot is end as there really can’t be anything as anti-existence but if the universe loops back on itself; it may not be an issue. Is there a possible way in the far future to semi-accurately measure its size...

I’m currently a senior in high school. All of my applications are finished and I am now in the waiting zone. At the same time I started to wonder what my future will be and frankly I was quite inspired by the discussion in 2006 about what does it take to become a mathematician. I was pretty...

Per Spacenews.com: It appears that Zhuque-2, built by the Chinese firm Landscape, failed to reach orbit yesterday. That was the first attempt to reach orbit using methane/oxygen boosters. However, more methalox orbital attempts are coming soon: * Relativity, a Long Beach, CA company that uses...

Hello everyone, I am Abheer and I am a high school student. Few days back I saw an article about RDEs (Rotating Detonation Engines). The article said it is the future of aviation propulsion. I want to ask, is it really so that RDEs are future or the low/high bypass turbofan engines will continue...

I was wondering if humans send spacecraft far enough into space in the future (for example Alpha Centauri or other star systems further away), is there any particular distance where it might make more sense to communicate between star systems by making a star blink with some sort of shutter...

Hi there! I am a student in my first semester of undergrad studies for computer science. The first assignment in my CSC class is to write a paper on the future of computer science, which can be broad or niche. My end goal is to get a job in mobile computing forensics analysis, so this is what I...

I tried creating a new Gmail account. I have several that have become de facto defunct (lost passwords with no way to recover). . . I've noticed every combination of words/letters for my attempted new username entry had been taken. That sucks. I had to literally come up with a stupid...

I'm running out of ideas for portable - which means single person carry, assuming the 'person' is a biomech Royal Guard bred for strength - weapons. I've used blasters, proton canons, disrupters that generate beams of spin-entangled top quarks... So, I'm up for suggestions that aren't the...

What do you recommend to read first, Supergravity by Freedman or A First Course in String Theory by Zweibach? For future consideration.

So north Korea announced its first COVID outbreak a few days ago and now nearly 200000 people caught the "fever with unexplained causes". North Korea itself has poor medical and anti Covid tools due to persistent sanctions against it. What do you think this will mean for the country and Kim Jong In?

The original article from Statnews, "Covid hasn’t given up all its secrets. Here are 6 mysteries experts hope to unravel" didn't sound right. SARS-Cov-2 is the virus, Covid-19 (Covid) is the illness (Coronavirus disease) or set of symptoms caused by the virus...

Tricycle Do you feel Tricycle racing can be considered a good contender as a potential game in future Olympic? Can Tricycle offers good speed to the cyclist?

1) Really messed up my uni life. Indulged into various addictions like addiction of making money online. making free money. wasted almost 3 years of uni life in it. 2.5 years to be exact.. Didn't keep notes of any subject even though i passed subject with ease as I had good track record of being...

Hi PF! I'm teaching a little unit on tectonic plates and have a question about the projected pattern of future plates. I know that plates can be broken into 2 (or more) new plates as the result of a continental rift. Our textbook also says that "The Atlantic seafloor may eventually become old...

Summary:: A proposal for keeping the Earth intact during the Sun’s Red Giant phase. The following is a hypothetical method for keeping our Earth in the Goldilocks zone during the Sun’s Red Giant phase offered for analysis and critique by those amongst us who are more knowledgeable than I. Your...

If you have half an hour to spare... I found quite a cool video. 😄 (sprinkled with David Attenborough, Brian Cox, NdGT soundbites hehe) my favourite bit's at around 17:00... when black hole go "brrrr" 😌

So I was trying to get a bit better handle on the definition of the difference between an event horizon and a Killing horizon. Locally they are indistinguishable, and the key difference (to my understanding) is that the event horizon is the last Killing horizon that escapes to future null...

Scientists finally created a 2D Supersolid! There existence has been predicted since the 60’s and now we have them. The scientists who created it don’t really know what it could be used for as it’s so much in the infancy stages, it’s practically a zygote. As an aspiring futurist, I was wondering...

Apart from, perhaps, Giorgio Parisi, are there any potential nobel prize winners from Italy or anyone who has worked in Italy?

A recent article on the Club of Rome 1972 prediction of fast economic growth leading to societal collapse in the 21st century: https://www.vice.com/en/article/z3xw3x/new-research-vindicates-1972-mit-prediction-that-society-will-collapse-soon

Hello everyone, I'm currently a physics undergraduate that just completed her second year of college. I love working physics problems and have always been passionate about going into physics research. My plan is to graduate and then go to a great/top grad school for my PhD that would allow me...

Which physicists are most likely to win the Nobel Prize in physics in 2021 and in the coming years?

Hello, Apologies if this is in the wrong section, it's related to circles so I figured Geometry was the best place. I found a very good example online that explains how to determine a future position of an object undergoing uniform circular motion: (Note that they made a mistake by writing...

I was really wanting to throw this out quickly since it was a time limited event already underway, but better late than never. The main point isn't the Gaming or Artistic nor the Combat part but rather...

From a thread in the Sci Fi section Is this really true? I've been in some pretty impressive public libraries in the past (well, not in 2020). I have also been in some pretty lame libraries, finding nothing of interest. Either way, I have not noticed a transition to digital collections of...

Hello everyone, I have to submit an assignment by Monday and there is only one part of the assignment missing, which is future developments of the Explicit Finite Difference Method. However, I can not do it because I really do not know what exactly he is asking me for on there. Could someone...

Just read this paper: https://arxiv.org/pdf/1906.04313.pdf At first it had me thinking that locally mediated, future dependent interpretations are the way to go. Yet it admits these seem to be rare relative to other types of interpretations. Any good intuition or reasons why this is rare in...

I just found this piece in an article: Terahertz waves (THz), which are submillimeter waves sitting between microwave and infrared light on the electromagnetic spectrum, have been used to achieve data rates greater than 100 Gbps. Unfortunately, THz waves share an Achilles’ Heel with the...

Way back in 2003, the Discovery Channel aired a speculative documentary called "The Future Is Wild." It portrayed some possible results of future biological evolution, first at 5 million years hence, then 100 million years hence, then 200 million years hence...

I want the board to use air to lift itself of with the coanda effect which is when air sticks at the bottom of somthing and proppels it upwards along with specially designed heliblades.l and I want somthing to cover tge blades and make it safe and I want it be compact like back invite future or...

Now that we have quantum computing how long before someone builds an AI ML system that can predict the future?

The definitions of currently popular computer languages assume only the technology of printing. For example, they provide syntax for printed expressions in one location that refer to printed expressions in other locations (e.g. "include" type syntax ). However, they don't assume that such...

Is this true?

Besides telepathy, what could I use to explain the properties of a device that is a TRUE universal translator, a handheld device that can decipher any language it encounters? I don’t know much about linguistics but I was told that even in a sci-fi setting, this is impossible. Jack Buchanan even...
