That's my opinion based on her history. I'm not going to argue. Just stating what I think.

@  Clara Listen... : (02 May 2020 - 05:40 PM)

A statement based on zero fact.

@  Belle : (02 May 2020 - 05:35 PM)

It would be worse if HiIllary had won

@  Clara Listen... : (02 May 2020 - 03:35 PM)

I doubt if China would continue to bully its way into the South China Sea with a different President.

@  Clara Listen... : (02 May 2020 - 03:20 PM)

Not with Trump in office. ;)

@  Fanta : (02 May 2020 - 04:55 AM)

:o. Thank you Clara.... But USA is always No.1.... :)

@  Clara Listen... : (01 May 2020 - 09:22 PM)

That's true but that never stopped Japan from being smarter. They were smarter when radios were made; they were smarter with car making; they were smarter in electronics. Now they're smarter about what to do with medicine.

Yes, Time Travel Is Possible; Here's How

 

 

pbmc1pmpnfi0vaihfgoy.jpg

 

 

 

Time travel's been one of man's wildest fantasies for centuries. It's long been a popular trend in movies and fiction, inspiring everything from Charles Dickens' A Christmas Carol to H.G. Wells' The Time Machine to the Charlton Heston shrine that is The Planet of the Apes. And with the opening of Interstellar today—n0t to spoil anything—we're about to fantasize about it even more.

The most fantastic thing? It's probably possible.

What's almost impossible

Let's start with the bad news. We probably can't travel back in time and watch the Egyptians build the pyramids. In the last century scientists came up with a number of theories that suggested it is indeed plausible to take a leap into the future; going back in time, unfortunately, is much more complicated. But it's not necessarily impossible.

 

Albert Einstein laid the groundwork for much of the theoretical science that governs most time travel research today. Of course, scientists like Galileo and Poincaré that came before him helped, but Einstein's theories of special and general relativity dramatically changed our understanding of time and space. And it's because of these well-tested theories that we believe time travel is possible.

One option for would be a wormhole, also known as an Einstein-Rosen bridge. Along with physicist Nathan Rosen, Einstein suggested the existence of wormholes in 1935, and although we've yet to discover one, many scientists have contributed their own theories about how wormholes might work. Stephen Hawking and Kip Thorne are probably the most well known. Thorne, a theoretical physicist at CalTech, even helped Christopher Nolan with the science behind Interstellar.

 

 

 

 

So let's just assume that wormholes do exist. In the late 1980s, Thorne said that a wormhole could be made into a time machine. According to Einstein's theory of general relativity, a wormhole could act like a bridge though space-time by connecting two distant points with a shortcut. Certain types of wormholes, it's theorized, could allow for time travel in either direction, if we could accelerate one mouth of the wormhole to near-light speed and then reverse it back to its original position. Meanwhile, the other mouth would remain stationary. The result would be that the moving mouth would age less slowly than the stationary mouth thanks to the effect of time dilation—more on this in a second.

 

But there are several major caveats of traveling back in time with this method. Chief among them is the simple fact that we'd need a method for creating wormholes, and once created, the wormhole would only allow us to travel as far back as the point in time when it was created. So we'll definitely never be spectators to Great Pyramids' construction.

 

The other really serious caveat is that we'd need a way to move one of the mouths of the wormhole nearly the speed of light. In their seminal 1988 paper on wormholes, Thorne and his colleagues assumed that "advanced beings [would] produce this motion by pulling on the right mouth gravitationally or electronically." We can't do that right now, however.

 

What we can do is travel into the future—but only by a little bit.

What's almost certainly possible

In recent years, we've seen some aspects of Einstein's fanciful theories proven true. The latest and perhaps most exciting theory is the aforementioned effect called time dilation. Though we've based technology on the theory for decades, an experiment finally proved this year that time dilation is absolutely a real phenomenon. It's also a phenomenon that could allow us to travel into the future.

 

Time dilation basically refers to the idea that time passes more slowly for a moving clock than it does for a stationary clock. The force of gravity also affects the difference in elapsed time. The greater the gravity and the greater the velocity, the greater the difference in time. Black holes, like the one depicted in Interstellar, for instance,would produce a massive amount of time dilation, due to their extreme gravitational pull.

 

Thanks to the space program, we've actually been dealing with this effect for many years. This is why the clocks on the International Space Station tick just a little bit more slowly than clocks on Earth do. Since the space station is moving so fast and is affected by less gravity, time moves more quickly. It's also why no clock on Earth is perfectly accurate, since the effect of time dilation means that time moves more slowly closer to the planet's surface. Okay, maybe one is almost perfect.

 

A better example of time dilation at work involves GPS satellites. The GPS chip in your smartphone works because there are 24 satellites circling the globe at all times that triangulate your location based on how long it takes time-stamped information to travel to and from the device.

 

However, scientists learned when building the system that the atomic clocks on GPS satellites do indeed run a little bit fast, since they're moving 9,000 miles per hour in orbit. To be specific, they lose 8 microseconds a day. That's hardly perceivable, but it's enough to throw off the location data. And so GPS technology makes adjustments to the clocks on board to account for the relativistic effects. The equation used is kind of complicated.

 

The implications of all this are huge. What if you took this to the extreme? If you jumped in a spaceship that flew super fast, time would pass more quickly for people on Earth. You could do a lap around the galaxy and return to Earth in the future. This is basically what happens in Planet of the Apes. In effect, Charlton Heston's character is a time traveler.

What's definitely possible (but kind of silly)

The question remains, can we really take it to that extreme? And is it possible to go backwards through time, too?

Once again, we don't really know. Einstein's theories tend to rule out rewinding time, but they're still theories. It's possible some future discovery could prove them wrong. As for the wormhole approach, we won't really know exactly how that works until we try it, and at the moment, we don't really have a feasible method for building a wormhole in space.

 

Hence, one easy way to find out is simply to search for time travelers walking amongst us. No laboratory required! And that's exactly what several zany scientists have done. (Spoiler: They haven't found any.)

 

If you're really curious about time travel though, go see Interstellar. The science behind it is sound—if sometimes a bit fantastic—but the movie itself is very fantastic.

 

Yes; they have very minorly traveled into the "future" - that is, less time has elapsed for them to reach this particular moment in time than for the rest of us. But time passes (imperceptibly) differently for everyone anyway, because whenever you have a velocity your movement through time changes.

 

Easiest way I've found to think about it (and I hope this helps someone): every single particle is traveling through 4D (or 10D, or 11D doesn't matter) spacetime at the speed of light. That velocity is divided amongst the various dimensions. The faster you're moving in the spatial dimensions, the slower you are in the time dimension.

 

The same thing happens between an athlete and a couch potato. The couch potato ages faster, while the athlete remains younger for a bit longer. Right? <_<

 

 

 

Personally, I believe in time travel. I think (very soon) it will be possible. To clarify, I think going to the future would be possible first. Much sooner than travelling to the past would be. What do you think? Well, so yes, I do believe in time travel... forwards only. That's essentially what Einstein's relativity theory is talking about. After all, it's been almost an hour since I posted this, so I've moved that amount of time ahead in time.  B) Sometimes this subject runs smoothly through my mind.. Other time (like now) I'm sort of..  :wacko:
