According to NASA, time travel is possible, just not in the way you might expect. Albert Einstein's theory of relativity says time and motion are relative to each other, and nothing can go faster than the speed of light, which is 186,000 miles per second. Time travel happens through what's called “time dilation.”
Where would you go if you had a time machine and why?
If I had a time machine with me, I would kept the “Good Things” in the world and erased all the “Bad things” from the world. I would implement all my dreams so that I can change the entire course of history. I would bring in new ideas that leads to beautiful and very finely rewritten present.
The simplest answer is that time travel cannot be possible because if it was, we would already be doing it. One can argue that it is forbidden by the laws of physics, like the second law of thermodynamics or relativity. There are also technical challenges: it might be possible but would involve vast amounts of energy.
Stories often focus on going back and either learn from or fix the past. To go and change something that would then make your return to the present happier, or so you imagine.
I wouldn't go back in time to change things because I would never have realized that I needed to stop blaming everyone and everything else for my problems. I would never have discovered that my failures and mistakes were a product of my own doing. I created the problems. I helped to fester them in my own mind.
A small group (11%) desired to relive an episode of their own past, and an even smaller group (5%) wanted to drop in on their descendants' future. Nearly a third of people wanted to travel to the past or to the future (29%) in order to gain strategic information (or to disambiguate their personal past).
In fact, according to Albert Einstein's famous equation, E = mc² , time travel is possible, at least in one direction. Going the other way — back to the past — presents a trickier challenge.
His idea was that, theoretically, the closer we come to traveling at the speed of light (186,000 miles per second), the more time would appear to slow down for us from the perspective of someone who, in relation to us, was not moving. He called the slowing of time due to motion time dilation.
A black hole's proximity will cause a clock's tick rate to be far slower than that of a clock on Earth. As shown in the film Interstellar, one year near a black hole may be equivalent to eighty years on Earth. This is how time travel via black holes is possible.
Time travel is still impossible because all these theories can't be tested practically. Scientists are trying to make a time machine, but it all seems possible in science-fictional movies.
What would you do if you could travel into the future essay?
The first thing I would do if I travelled in the future is I will meet my self first then my family & my friends. I will know everything what is going to happen in my life before it happens. So I can learn accidents in my life and also in my loved one's life and I will prevent it. I really like superhero movies.
While researchers have never found a wormhole in our universe, scientists often see wormholes described in the solutions to important physics equations. Most prominently, the solutions to the equations behind Einstein's theory of space-time and general relativity include wormholes.
Thanks to Einstein, we know that the faster you go, the slower time passes--so a very fast spaceship is a time machine to the future. Five years on a ship traveling at 99 percent the speed of light (2.5 years out and 2.5 years back) corresponds to roughly 36 years on Earth.
wormhole, solution of the field equations in German-born physicist Albert Einstein's theory of general relativity that resembles a tunnel between two black holes or other points in space-time. Such a tunnel would provide a shortcut between its end points.
Best known for developing the theory of relativity, he is amongst the top most geniuses the world has recognized. Einstein never took an IQ score test. However, based on his historical records, academics have estimated his score to be around 160.
Does Stephen Hawking think time travel is possible?
According to Stephen Hawking, time travel is possible, and not just in the way we might think. Backward time travel is not supported by Hawking's theories, because new matter (a new you) would need to be created – one existing in the past and one in the present, traveling back in time.
Albert Einstein famously expressed this point when he wrote to a friend, “The past, present and future are only illusions, even if stubborn ones.” Einstein's startling conclusion stems directly from his special theory of relativity, which denies any absolute, universal significance to the present moment.
The total traveling time is the actual amount of time the trip takes from your departure city to your final destination, according to your itinerary. This calculated time takes into account changes in time zones, time spent in transfer cities and daylight saving time (DST).
Why is it hard for us to understand how a singularity works?
Why is it hard for us to understand how a singularity works? Mathematical equations break down and return answers of infinity approaching a singularity. In order to find the Schwarzschild radius, you just need to know the: mass of the object.
Every time we remember something from the past or imagine something that will happen in the future, we engage in mental time travel. Scientists discovered that, whether we mentally travel back into the past or forward into the future, some of the same brain regions are activated.
Although many people are fascinated by the idea of changing the past or seeing the future before it's due, no person has ever demonstrated the kind of back-and-forth time travel seen in science fiction or proposed a method of sending a person through significant periods of time that wouldn't destroy them on the way.
“Episodic future thinking” or EFT is often described as “mental time travel” — your brain is working to help you see and feel the future as clearly and vividly as if you were already there. Filling in the blanks takes considerable effort. But that's precisely why this kind of imagination is so powerful.
