id change my past, the butterfly effect would still happen, but if you went back, for the sole purpose of changing something, wouldnt that thing you changed be for the better?

Like for example, say you built a time machine today, and went back in time to 10/9/01 (9/10/01 for you Americans) - would you not inform the police and army and do everything you could to stop the 9/11 terror attacks? Therefore making the world obvious to terrorism in general like it was pre 9/11? I know I sure as hell would.

who are we to tamper with history like that. Things should not be changed.

Besides, time travel is not possible. What's done is done.

Well, in the realm of our knowledge of science.... I mean, we don't know everything there is to know about the universe, planes of existance, etc..... We can say it's not possible because up until this point we have not been able to accomplish it..... But think about this. At one time, no one thought that we could travel to the moon.

Yes, its unlikely that time travel is possible, but because we humans are not all knowing of the complexities to the universe, we can never say for certain that it is not possible.

yeah but would they believe you?

Should you be in that position, don't say you're a time traveler if you want to get anything done, lol.

The thing about time travel is that there's so many paradoxes. I feel like, even if time travel is discovered, it will be highly regulated and shunned simply because the consequences of what it will do are greater than any benefits it can provide. Think about it; perhaps passing by someone can cause you to never be born, but that would mean you never went there to begin with so you would exist and...

Nothing would happen that we know about. I'm of the school of thought that every possibility is accounted for already an stuff branches out into it's own dimension. In QM the act of observing is enough to alter the outcome probably because you are focusing in one moment in time and beyond that moment lies what seems like an infinite amount of paths and possibilities.

I've just decided to reply to this message but there is probably another me that didn't want to reply to it and his world is carrying on regardless which makes time travel more of an act of prediction.

Again I lack the knowledge to properly explain myself, so I'll pass myself over to Schr?dinger's cat.

Schr?dinger's Cat: A cat, along with a flask containing a poison, is placed in a sealed box shielded against environmentally induced quantum decoherence. If an internal Geiger counter detects radiation, the flask is shattered, releasing the poison that kills the cat. The Copenhagen interpretation of quantum mechanics implies that after a while, the cat is simultaneously alive and dead. Yet, when we look in the box, we see the cat either alive or dead, not a mixture of alive and dead.

If you go back in time and change an event, from that event onwards a new dimension would spawn (a new reality with that event). However, you wont of changed the event from happening in your original timeline (As that event happend in your dimension, otherwise you wouldnt of come back), so it wouldnt fix it for you but for an alternate you.

The thing you have to remember is, if you go back in time and change an event... you're not destroying your original timeline (dimension), you're just creating a new (your original timeline still exists, the past events still happend and the future is still playing out).. you've just created a new timeline (dimension) with the event changed.

sadly, i think they would throw you in jail for making such claims. and if you said you were 8 years and two months from the future, you'd be going with the men in white lab jackets.

then a day later... yeh

Impossible.

You can't "travel" to the future... it hasn't happened yet. You could, theoretically, go into suspended

animation and wake up in the future... but then again, you do that every night.

As for the past, I'm of the thought that it can't be "changed". If YOU travelled to the past and changed

an event... say, killed Hitler... then as far as I would be concerned, Hitler died when you killed him.

As far as the rest of the world would be concerned, he died when you killed him. Therefore, nothing "changed"

as far as anyone is concerned. And you couldn't then travel back to your future because it no longer exists.

It has been theorized that "alternate realities" exist due to this. I live now. I know who won the last Superbowl.

If you went back and changed the outcome, I would not suddenly remember differently. My present would remain

constant. YOUR present, however, would be the one you just created. Me, in THIS present, is a completely different

person that the one you may encounter in your past (now your present).

I like ur way of thinking here, was thought provoking :)

All we need is a Stargate and a Solar Flare ..

Check your cupboards everyone.

<giggle> man i SOOO wanna open the cupboard behind me at work and find a solar flare or other such interesting items, why oh why does it have to be just full of boring things like my work files (Im at work) and vegemite (yes a boy does gotta eat while at work too)

If you go back in time and change an event, from that event onwards a new dimension would spawn (a new reality with that event). However, you wont of changed the event from happening in your original timeline (As that event happend in your dimension, otherwise you wouldnt of come back), so it wouldnt fix it for you but for an alternate you.

The thing you have to remember is, if you go back in time and change an event... you're not destroying your original timeline (dimension), you're just creating a new (your original timeline still exists, the past events still happend and the future is still playing out).. you've just created a new timeline (dimension) with the event changed.

This whole idea of new dimensions being spawned, I like to think it would happen that way. Then again, lets just say time travel is possible, I like the idea that for our current timeline to happen, with in our potential future to occur, if someone has come back in time, then everything that has happened before, has relied on that person being there at the time that it happened.

Man i love movies on time travel and things like this, for all the different ways that it could go, and the whole action and consequence thing.

I mean lets just say to guys come back from the future, and they are all 'hey lets be careful and not do anything' if we go with that it alters the single timeline/reality, then anything and everything that the do, be it on purpose or by mistake or not even knowing about it (ie stepping on a bug) had to have happened so that the current timeline could play out, so that they could end up being in a position in the future to come back.

But then when you put it that way the whole idea of free will goes out the window.

Anyone heard of the time happens in cycles theory? Think Terry Pratchett, The Matrix and Battlestar Galactica - everything has happened before and will happen again. Thinking of that idea means no matter what you do, time travel or not, it will all play out similar in the end.

Doesn't make sence. If you go back in time to do anything, and you do it, your future self wouldnt need to do it, so you wouldnt have gone in the time machine in the first place, undoing what you just did, and you would be stuck in 1 Infinate Loop :o

The problem with time travel is that if it's ever made possible then there is the added problem of that person going back and introducing the technology long before it existed. Judging by the fact that hasn't happened yet its safe to predict that one can't travel back in time, forward however is debatable.

Don't we already travel, very slightly, in to the future on aeroplanes? Or more so astronauts in space for prolonged periods of time.

There's a difference between moving through time faster, than going into the future. The former, relatively you are moving in slow-mo to everyone else, and the latter, future has not yet happened.

      Microsoft Weekly: Xbox exclusives are back, big Windows app updates, and more by Taras Buria This week's news recap is here. Microsoft is returning to XBOX exclusives, Windows 11 gets new preview builds, the Low-latency Profile is here, big updates for inbox Windows apps, Patch Tuesday updates, and more. Quick links: Windows 10 and 11 Windows Insider Program Updates are available Reviews are in Gaming news Great deals to check Windows 11 and Windows 10 Here, we talk about everything happening around Microsoft's latest operating system in the Stable channel and preview builds: new features, removed features, controversies, bugs, interesting findings, and more. And, of course, you may find a word or two about older versions. The June 2026 Patch Tuesday updates are now publicly available. Windows 11 users can download KB5094126, which introduces plenty of new features and security updates, including the Low-latency Profile for better performance, shared Bluetooth audio support, and more. Windows 10 users with PCs enrolled in the Extended Security Update program can download KB5094127. In addition, Microsoft released new Defender updates for its operating systems. Speaking of Defender, Microsoft will now deliver EDR updates via Microsoft Update for faster security improvements independent of Patch Tuesday updates. Following the release of this month's Patch Tuesday updates, Microsoft also published new Windows 11 images available in the Media Creation Tool app. Now, you can create bootable USB media for clean Windows 11 installations with the latest releases. Some unfortunate stuff is going on with certain PCs from Dell and HP. Dell acknowledged that the SupportAssist bug causes black screens of death, while HP systems are suffering from Secure Boot update issues and boot loops. Both companies issued official advisories. Windows Insider Program Here is what Microsoft released for Windows Insiders this week: Builds Canary Channel Builds 29610.1000 and 28120.2302 This week's "Canary" builds only contain performance improvements and fixes, including the Low-latency mode, which is now available in the Stable channel for all Windows 11 24H2 and 25H2 users. Dev Channel Build 26300.8687 Microsoft brought some useful File Explorer changes with this build. You can now open folders in a new tab by middle-clicking them in the address bar. Beta Channel Build 26220.8680 and 28020.2298 Screen Tint, improved Windows Widgets, and other enhancements are included in this week's Beta releases. Release Preview Channel Builds 26200.8728 and 26100.8728 These builds also feature better widgets, new Windows Update controls, point-in-time restore, File Explorer improvements, and more. In addition to new Windows 11 preview builds, Microsoft announced that inbox Windows 11 apps now have their dedicated release notes in the official documentation. Also, Microsoft dropped massive feature updates for six apps, including Paint, Clock, Calculator, Camera, Media Player, Photos, and more. Updates are available This section covers software, firmware, and other notable updates (released and coming soon) delivering new features, security fixes, improvements, patches, and more from Microsoft and third parties. Google has some bad news for those still using MV2-based extensions in Chromium-based browsers, particularly Chrome. The company is now removing flags responsible for Manifest V2-based extensions (uBlock Origin is one of the most popular). However, some browsers resist this change, and Opera issued a statement that it will allow users to continue using MV2 extensions for as long as possible. While Microsoft is still not ready to share new details about MV2 extensions in Microsoft Edge, the company shared important details about the way it will be updating the browser going forward. Now, Microsoft wants to update Edge every two weeks across all platforms instead of the current four-week schedule (only the Extended Stable is exempt from this change). This week, Microsoft confirmed a useful new Teams feature that is coming to the messenger soon. It also detailed all the improvements that made the platform better for users in 2026. However, not all changes are great, as the company is moving ahead with the check-in feature, which many believe will lead to employee monitoring. PowerToys received a feature update this week. Version 0.100 arrived with a big rework for the Shortcut Guide, a new extension gallery for Command Palette, new Dock features, and plenty of other changes. Here are other updates and releases you may find interesting: Microsoft is bringing big performance improvements to OneDrive on Mac Popular Windows 11 file manager Files gets improved tags, layouts, and a new OneDrive icon New Outlook for Windows and Web is getting a simple but very useful email feature Microsoft had to shut down 70+ GitHub repos after getting hacked, bringing back some Microsoft AI boss no longer believes that AI will replace human workers Microsoft wants to end printer driver headaches with Windows Ready Print SQL Server Management Studio 22.7 brings "What's New" page, T-SQL formatting, and lots more Microsoft releases Visual Studio Code 1.124 with smarter autonomous AI agents Windows Server gets DNS over HTTPS (DoH) support Here are the latest drivers and firmware updates released this week: NVIDIA 610.52 Hotfix with multiple fixes for black screens of death, sleep issues, G-SYNC, and more. Reviews are in Here is the hardware and software we reviewed this week Steven Parker reviewed a rather unorthodox device here on Neowin this week. He took for a spin the DWARF mini, the world's smallest smart telescope for night and day sky captures. It tracks objects in the sky, has a sun filter, and has a low learning curve. There is also nice build quality and a quite affordable price. Pulasthi Ariyasinghe reviewed 007 First Light. The game turned out to be a satisfying spy adventure in the James Bond universe with great gunplay and combat, impressive crowds, over-the-top action sequences, and more. There are a few quirks here and there, but overall, the game scored high on our scale. On the gaming side Learn about upcoming game releases, Xbox rumors, new hardware, software updates, freebies, deals, discounts, and more. Microsoft held the latest XBOX Games Showcase this week.

    • Microsoft Flight Simulator's City Update 15 enhances Midwest cities

      By LoneWolfSL · Posted

      Microsoft Flight Simulator's City Update 15 enhances Midwest cities by Pulasthi Ariyasinghe The third major city update of the year has landed for the original Microsoft Flight Simulator and the 2024 release. The latest drop is upgrading the visuals and regional accuracy of three metropolitan regions in the American states of Illinois, Minnesota, and Wisconsin. The 15th city update is adding eight new areas of interest that have been enhanced with high-fidelity TIN (triangulated irregular network) surface texturing in the mentioned regions. The free update highlights Chicago, Elgin, Cicero, and Arlington Heights in Illinois, as well as Minneapolis, St. Paul, Bloomington, Duluth, Brooklyn Park, Woodbury, Lakeville, Plymouth, and Blaine in Minnesota. In Wisconsin, the development has also upgraded the lands and buildings of Milwaukee, Madison, and Racine. The update lands just as one of the world's largest enthusiast flight simulation conventions, FlightSimExpo, kicks off in downtown St. Paul, Minnesota, on June 14. The Flight Sim development team's 40-minute keynote at the event can be watched here. At the same time, Microsoft is bringing the 6-seat, single-engine, multi-use light civil airplane Piper M600 into the game as a part of its Expert Series 2 program. This premium plane can be purchased from the in-game marketplace for $24.99. City Update 15: The United States Midwest is now available in Microsoft Flight Simulator, as well as the newer Microsoft Flight Simulator 2024, as an optional download. It can be accessed across Steam and the Microsoft Store for PC, Xbox Series X|S, and PlayStation 5, as well as Xbox and PC Game Pass subscriptions. Xbox One, mobile, and PC players can also jump into the new content using Xbox Cloud Gaming if they have a Game Pass Ultimate membership. The game must be updated to the latest version to download this free update from the in-game marketplace.
    • Five things you might have missed during Apple's WWDC 2026

      By Aditya Tiwari · Posted

      Five things you might have missed during Apple's WWDC 2026 by Aditya Tiwari Image: Apple Apple's annual developer event, WWDC 2026, happened from June 8 through June 12. We have already covered several new features and updates that the iPhone maker unveiled during the official keynote. Apple took Google's help and finally announced the upgraded Siri AI personal assistant, which now comes with an app. Moreover, a truckload of Apple Intelligence features took the center stage. That said, this year's WWDC is a bit different, and you might have noticed or missed the following stuff: Apple's ongoing unification of platforms Image: Apple One thing Apple is widely known for is its seamless hardware-software ecosystem. The company added a new chapter in 2020, when it began the Apple Silicon transition and launched macOS 11 Big Sur with native ARM support. Some major changes happened last year as well, when Apple renamed all of its operating systems to version 26 and introduced the Liquid Glass design language. Until WWDC 2025, Apple keynotes had dedicated segments for iOS, iPadOS, macOS, watchOS, and other operating systems, in which the company discussed each in detail. The WWDC 2026 keynote was different, and Apple allotted most of the screen time to Apple Intelligence and Siri. It didn't even publish separate press releases on its website for different operating systems. While it might seem surprising at first, it shows how Apple plans to move forward with its software ecosystem. Be it the Liquid Glass changes, child safety updates, or other features, they are mostly rolling out across multiple platforms. In other words, Apple is slowly blurring the line between its operating systems and achieving feature parity wherever possible. It's easy to rule out that someone in Apple's marketing team forgot to press the publish button. Everything is a calculated move when it comes to a company like Apple. Putting Apple Intelligence left, right, and center hints that the OS itself is no longer the product anymore. It's Siri, not Pepsi Time and again, various Apple products have been compared to unrelated things and turned into meme material. You might have heard about the "cheese grater" Mac Pro or the "trash can" Mac Pro, to name a few. It's Siri's turn this time. The upgraded AI assistant got a fresh logo, and people have started comparing it with Pepsi. There are other contenders, such as the Sony Ericsson logo and the Yin and Yang symbol. Shot on iPhone. Edited on Mac Image: Apple Apple has been putting the iPhone's camera muscles to the test on various occasions. Even NASA astronauts took it to Space earlier this year and captured some out-of-this-world photos. Recently, Apple TV streamed the first major live sporting event shot entirely on iPhone 17 Pro: an MLS match featuring the LA Galaxy vs. the Houston Dynamo FC. The 'Pro' iPhone has also been used to shoot Apple events in recent years. It's "Scary Fast" Mac event in 2023 was among the earliest attempts, and the tradition trickled down to the WWDC 2026 keynote, which ended with the tag line "Shot on iPhone. Edited on Mac." It's unsurprising to see Apple flexing the camera capabilities of its Pro models, especially when it has been baking professional-grade features, including ProRes RAW and Genlock. Hints for the foldable Apple has been sitting on the foldable iPhone for so long. There is still confusion over when the company will make it official. A recent report said that the iPhone Fold might get delayed as Apple is struggling to perfect its hinge mechanism. But Apple has been dropping hints here and there. A developer dug into the iOS 27 beta code and found internal references about device folding states. As verified by Macworld, the code includes references to "foldState" and "angleDegrees" internal status values, which are apparently designed to tell apps if a device is folded and at what angle. As of now, no other Apple device uses these states. The publication also found internal code suggesting Apple has been testing a device with both Touch ID and Dynamic Island, a combo that doesn't exist today. Last event as Apple CEO Image: Apple Tim Cook's bond with Apple is now almost three decades old, having started in 1998 as the SVP of Worldwide Operations. Back in August 2011, Steve Jobs stepped down as Apple CEO months before his passing, and Cook took charge. Now, the baton has been passed to the hardware chief, John Ternus, who will take over the role on September 1. WWDC 2026 is the last major Apple Event for Tim Cook as CEO. We have seen so much during Cook's tenure over the years, much of which defines Apple as we know it today. From new hardware product lines like Apple Watch, AirPods, Apple Vision Pro, and Apple Silicon, to boosting Apple's services business with Apple Music, Apple TV, Apple Pay, Apple Arcade, Apple Fitness+, Apple Care One, and more. That said, the first developer betas for Apple's latest operating systems are now available. You can check if your device is supported on iOS 27, iPadOS 27, macOS 27 Golden Gate, watchOS 27, and other platforms. What's your favorite feature that Apple announced this year at WWDC 2026? Tell us in the comments.
