time travel.. something to think about..


Recommended Posts

What if in the future they figured out a way to time travel. Forwards and backwards. What if someone came back to today, would they be able to teleport back? or would they be stuck in time hehehe. sorry its such a random topic; i couldn't find any neowin chat room here....

just something im pondering ATM

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.

yeah but would they believe you?

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).

It's a paradox no matter what you do. If you travel back in time, then your future self would have no desire to travel back in time, so you would never travel back in time to begin with. That's the way I see reverse time travel anyway...

But could time travel not shift the time traveller into a alternate timeline, rather than alter the future/present of the present time line?

My own theory ... if time travel became possible, it'd be made illegal striaghtaway, simply because some greedy

buggers would abuse it for their own personal gain, like going forward in time, and finding out next Saturday's

all the winning numbers on the National Lottery thus guaranteeing at least one big jackpot win.

One other reason why time travel would be made illegal ... going back in time, changing something about any

major historical event, which could have massive repercussions for the present time and possibly the future.

Supposing someone were to go back to 1939 Germany, and tells Hitler how to avoid being defeated?!?

Although time travel based sci-fi shows like Doctor Who are made to be completely fictional, The Doctor is

right that things that happened in history are fixed points in time, and they must always stay that way.

From a scientific standpoint, it's (theoretically) much easier to "travel" forward in time than backward. It's theoretically possible to bend space and time so that past events can be witnessed, but not altered. Travelling forward in time involves very fast space craft and extremely large amounts of gravity (eg. big stars, black holes, etc.).

What if in the future they figured out a way to time travel. Forwards and backwards. What if someone came back to today, would they be able to teleport back? or would they be stuck in time hehehe.

Considering you said that it's possible to travel forwards and backwards, wouldn't it be logical that they could travel back to their time?

    • Calling GTA 6 overhyped crap doesn’t make you edgy, it just makes you sound like someone who hasn’t enjoyed anything since the PS2 era.
    • I’m not arguing whether Rockstar likes money. Obviously, they do, they’re a business. I’m saying this isn’t new. They’ve always launched console first. This is just how Rockstar operates.
    • I'm not sure how old the school is, but they've been doing this since GTA 3. Back in those days we'd be lucky for game companies to release on the PC at all. And with the current state of Sony (or Microsoft) their gaming wing won't be getting a penny from me.
    • We now know when and how the Universe may truly end by Sayan Sen Image by Marek Pavlík via Pexels| Not representative A study by physicist Henry Tye of Cornell University suggests that the universe may not expand forever. Instead, it could eventually stop expanding, begin contracting and end in a "Big Crunch" roughly 20 billion years from now. The research, published in the Journal of Cosmology and Astroparticle Physics, was conducted by Tye, Horace White Professor of Physics Emeritus at Cornell University. Using recent observations from major dark-energy surveys, Tye and his collaborators developed a cosmological model that predicts the universe could have a total lifespan of about 33 billion years. Since the universe is currently estimated to be 13.8 billion years old, the model places it near the midpoint of its existence. According to Cornell University's summary of the research, the study centers on the cosmological constant, a term introduced by Albert Einstein in his theory of general relativity. In modern cosmology, the cosmological constant is commonly used to describe the simplest form of dark energy, the unknown phenomenon believed to be driving the accelerating expansion of the universe. "For the last 20 years, people believed that the cosmological constant is positive, and the universe will expand forever," Tye said in a Cornell University news release. "The new data seem to indicate that the cosmological constant is negative, and that the universe will end in a big crunch." The study draws on data from the Dark Energy Survey (DES) and the Dark Energy Spectroscopic Instrument (DESI), two major projects designed to investigate the nature of dark energy. According to Tye, recent observations suggest that dark energy may not behave exactly like a simple cosmological constant. To account for those observations, Tye and his collaborators proposed a model involving an extremely light hypothetical particle that evolves over time. In their calculations, this produces a negative cosmological constant and leads to a future collapse of the universe. The model predicts that cosmic expansion would continue for approximately another 11 billion years before reaching a maximum size, after which the universe would begin contracting and eventually collapse. Scientists have long debated how the universe might end. As explained in an article published in The Conversation by Stephen DiKerby of Michigan State University, several possibilities have been proposed. If dark energy remains constant and positive, the universe could continue expanding indefinitely, gradually becoming colder, darker and more diffuse in a scenario often called the "heat death" of the universe. Other theoretical possibilities include a Big Rip, in which cosmic expansion accelerates so dramatically that galaxies, stars and even atoms are torn apart, or a Big Crunch, in which expansion reverses and the universe collapses back into an extremely dense state. DiKerby notes that the Big Crunch idea itself is not new. What distinguishes Tye's work is that it attempts to use current observational data to estimate when such a collapse might occur and how it could unfold. Much of the universe's long-term evolution remains uncertain. According to current astrophysical understanding, stars will continue to form and die for billions of years. The Sun, for example, is about halfway through its expected lifespan. Galaxies are also expected to continue merging; the Milky Way and Andromeda galaxies are projected to collide several billion years from now. At the same time, the nature of dark energy remains one of the biggest unanswered questions in cosmology. While observations indicate that the universe's expansion is accelerating, scientists still do not know what is causing that acceleration. Future observations may therefore alter current predictions about the cosmos's ultimate fate. Tye emphasized that additional evidence will be needed before firm conclusions can be drawn. DESI continues to collect data, while upcoming observations from missions and observatories including Euclid, SPHEREx and the Vera C. Rubin Observatory are expected to provide more precise measurements of dark energy. "People have said before that if the cosmological constant is negative, then the universe will collapse eventually. That's not new," Tye said. "However, here the model tells you when the universe collapses and how it collapses." For now, the study presents one possible future for the cosmos rather than a settled prediction. Whether the universe ultimately ends in a Big Crunch, expands forever, or follows another path entirely remains an open question that future observations will help answer.
