Who said anything about "me" returning to the past to give that information? Doesn't matter who will do it, as long as the information that speeds up the process of discovery will be transferred.

It would break the rules. Can you or I say what would happen if Kennedy hadn't been shot?

Let's go with time travel. Let's say that in the future we find a way to travel back in time. A man on the team that makes the discovery decides to go back in time to our present day and let us know how to travel through time. In that circumstance, by doing such a thing he has changed the course of history. Now that we know how time travel works, he will never be on the team that makes the initial discovery because that is in our future. But if he didn't make the initial discovery, how was he able to come back in time to tell us how to make the initial discovery?

That just means that time traveling worked and that we already use it, because someone from the future returned to our current time and told us how to build time machines. And as we know how to build and use it, what happens in the future doesn't matter as we already have the technology.

Now I'm not seeing any ads that are selling me time machines, so that means we didn't discovered how to time travel in the future.

It would work that way if we lived in alternate universes and the traveling back split our universe into another one with a completely different set of events after the visit is made but the paradox solution is a different thing entirely, if the universe works like that then it is simply not possible to do what you say. :/

Unless I'm correct, and we've put rules in place to stop changing our future/their present. The Butterfly Effect comes in to play, but what you're saying is that it won't make a difference. So let's go one step further, and let's say someone from the future comes back and tells me how to time travel. Let's then say that I go and take a nuclear bomb (because, you know, I have a couple stashed downstairs in my basement...for reasons) and go back in time to the time of the Neanderthals. I then use that bomb and blow a big hole in what would later be known as England. In the process I've wiped out many people, some of who would have given birth to kings, conquerors and the like.

You can argue that it wouldn't matter, as we would never know that it happened - or rather, we would know that it happened but we wouldn't necessarily appreciate the impact it had because it has now become a part of our history.

"Dangerous" doesn't really do the situation justice. Better the enemy/timeline that you know, and all that.

EDIT: Are we bringing alternative universes in to this?

Where on earth did I say that if we get information from the future on how to time travel, that it won't effect the future (from present time)? I just said that how it will effect the future is not important. Same ###### to your "what if" atom bomb in the past; will have effect on the future of that "what if", but we don't know to what point and guessing is useless.

 

And we don't. This is a discussion about time traveling and not alternative universes.

...but we don't know to what point and guessing is useless.

Then while you may have answered the question, you're missing the issue. The fact that we would be unable to predict the complete outcome of any change in history, affecting both our present and future, is a big idea. Which, along with the original question, brings me to the idea of, "even if it was possible, should we be able to do it?"

But I guess we digress.

I believe in time travel and I think there have been those who traveled back to our time.  I think that the UFOs that some people may have encountered or saw are actually future evolved humans that have come back to our time to observe how we lived similar to how our scientists study past animals and civilizations.

You are correct. ;)

What I find funny is some of the people in here are so certain with their answers.  They are so sure it is possible or not possible one would have to wonder what all the debate is about with physicists.   Heck - these people in  neowin already know all the answers. :D

If there is one thing we have learned from the past, it is to never say something is "impossible". 

I have studied quite a bit about theoretical physics, different multiverse theories, quantum entanglement & if there is anything I have learned from this - it is that I dont know crap.   So it is so refreshing to see so many people that are so steadfast in their beliefs about theoretical physics. /s

 

 

As an individual with a PhD in Physic the only answer on my mind is, "Hell No."

Care to elaborate ? I like to hear your thoughts, especially if they are unique.  Ive read all the usual theories, understood most - so I'd like to hear another.

(you dont have to go into great detail if you dont want to)

Thx

Open-minded or close-minded, laws of the universe remain in place. No matter how open-minded, you cannot make a frying pan out of chocolate.

you could if you had a Star Trek Replicator :drool:  :punch:

I think time travel is possible, but only to the future.

 

Time is relative to the person observing it, and as you travel closer to the speed of light, time slows down for that person. So if you travelled for a year at (or close to) the speed of light, for everyone else 1000's of years would have passed.

 

They've done experiments whereby two atomic clocks on the ground are synced, one is sent into an airplane and flown around the world a few times and when you compare the clocks there are differences (albeit very small) between the two.

Interesting. Care to elaborate? Personally I think that black holes are the closest that we'll get to time travel, but I cannot vouch for the idea that it will let us go backwards or forwards on ourselves in a true time traveling sense.

Then there are Wormholes.

Wormholes are theoretical folds in space, I believe, they only deal with time insofar as using a wormhole would have the potential to reduce the travel time from point a to b. </nerd>

You can't see other galaxies. Guess they aren't real then. 

 

But he can't see them with your eyes. Mustn't be real then right. Can't see red ######. Isn't real. Graphs are fake. 

 

 

 

 

None of that has any relation to what macoman said. There is ZERO evidence for alien life, there is evidence for other galaxies. 

 

 

I suggest you all watch Source Code: http://www.imdb.com/title/tt0945513/

 

I'm not saying it's completely accurate, it's a movie after all, but still much better than all those fantastical time travel movies.

 

 

That would be more in relation to alternate realities, not time travel.

 Which is the thing that happens when one supposedly "time travels" to the past.

 

Yes, in the movie it's not done physically, but still. I think we could call them parallel universes than alternate reality.

That really depends on who's idea you are basing time travel on. There are some that believe if you could travel back, you would stay within your own reality and others think you would jump back into a different branch of reality. There is no one winning view of which one it would really be, it's all science fiction.

    • Google reportedly limited Meta's Gemini access over limited AI compute

      By Karthik Mudaliar · Posted

      Google reportedly limited Meta's Gemini access over limited AI compute by Karthik Mudaliar Google is reportedly limiting Meta's use of its Gemini AI models after Meta tried buying more computing capacity than even Google could supply. According to the Financial Times, Google told Meta in March that it could not provide the full Gemini capacity that Meta had requested. This shortfall even disrupted and delayed some of Meta's internal projects. Due to this, Meta even told its employees internally to use AI tokens more efficiently. Meta wasn't the only one to get hit by this sudden refusal by Google; even other customers were affected. But Meta was hit harder because of its unusually high demand for Google's models. The move from Google makes it evident that companies all over are in limited supply of both infrastructure and compute. Alphabet said in April that Google Cloud revenue grew 63% year-over-year to $20 billion in the first quarter, helped by enterprise AI infrastructure and AI solutions. In pursuit of more compute, Meta had earlier signed a multi-billion-dollar AWS agreement as well as a large AMD GPU deal for AI data centers. But the crunch would be short-lived as both Meta and Google have also ramped up infrastructure investments heavily. Meta said in November that it was committing more than $600 billion in the U.S. by 2028 for AI technology, infrastructure, and workforce expansion. In the first quarter of this year, Meta also raised its expected capital expenditure for 2026 to a range of $125 billion to $145 billion, citing higher component pricing and additional data center costs for future capacity. However, this doesn't make the company immune to the current dependence on outside suppliers. Meta has also spent many years promoting Llama as an open-weight alternative to closed models from Google, OpenAI, and Anthropic. But if the reported reliance on Google's Gemini models is severe enough for internal work to get impacted, then it looks like even frontier labs and Big Tech aren't fully self-sufficient.

    • Samsung, Amazon extend 990 PRO 2TB NVMe SSD deal beyond Prime Day 2026

      By seeprime · Posted

      I like to reminisce about the good old days, way back in autumn 2025 when building a gaming machine was fun and the drives were about $150 when you caught a deal. Yes duh, back in the day we had it gone. Then baby Skynet came along, hiding in AI datacenters demanding more processing power until it reached singularity. End of a not totally fictional story.
    • Bypassed Windows 11 shows surprising stability on ancient, completely unsupported hardware

      By +Spark99 · Posted

      My experience in the past with older Windows 11 builds was not great on unsupported machines but I recently used Rufus to put the latest build on a older 5th Gen Core Thinkpad T that we upgraded with a SATA SSD and 8GB of RAM four years ago when hardware was reasonable and it seemed pretty fast and solid. Customer is very happy with the performance and will probably get four more years out of that venerable laptop that he loves so much. Another customer just retired his Dell Studio laptop from 2009 running Windows 10. It got an SSD over 10 years ago and did everything he needed it to for 17 years but he also retired last year and is happy doing everything on his iPad now.
    • Apple's newest AirTag 2 gets first big discount

      By TarasBuria · Posted

      Apple's newest AirTag 2 gets first big discount by Taras Buria In late January 2026, Apple introduced its second-generation AirTag trackers, bringing a refresh to the old model that has been on the market for half a decade. Now, you can get these new trackers at an all-time low price, thanks to the first big discount that brought the price down by 17% on Amazon. While the second-generation AirTag looks identical to its predecessor, it packs meaningful upgrades inside. The second-gen ultrawideband chip works 50% farther than the original AirTag, allowing you to detect lost items in a wider range. In addition, the second-generation AirTag features an upgraded Bluetooth chip for extended range and a significantly louder speaker (up to 50%) so that you can hear it better when locating a lost item. Note that the second-gen AirTag only works with iPhones and iPads that run iOS/iPadOS 26 and newer, so you need a compatible device to use the tracker. Like the original AirTag, the AirTag 2 is available in two packs: one and four pieces. Both are now available at a notable discount on Amazon, and you can purchase them using the links below. Apple AirTag 2 tracker - $24 | 17% off on Amazon Apple AirTag 2 tracker (four-pack) - $89 | 10% off on Amazon Good to know This Amazon deal is U.S.- specific and not available in other regions unless specified.

    • Tidal won't monetize AI slop music, company says

      By monterxz · Posted

      I've been on Deezer for over a decade, but glad that Tidal joined them in fighting AI slop. Can't stand such takes as Spotify's: "Spotify's CEO recently pushed back against listeners who call AI music "slop," urging people to stop using the term and instead embrace the creative potential of AI music."
