WILL TIME TRAVEL REALLY BE POSSIBLE IN 2100? Colin Stuart, author of The Big Questions in Science, estimates humans will be able to jump ahead to see our future by 2100 – 85 years away. 'Time travel to the future has already been achieved, but only in tiny amounts,' he said.
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.”
By 2100, all-new, high-speed railway systems—or even hyperloops—will have replaced the current and outdated one. Systems that are in the first phase of production, like the one from L.A. to San Francisco, are just the beginning.
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.
What did Albert Einstein say about time travel? Einstein stated that it is possible for one to travel into the future if one travels at the speed of light. If this were to occur, the individual would age slower than those on Earth, traveling at its speed.
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.
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. You will find several people claiming to time travel, like Alexander Smith. But no one has concrete proof to support their claim.
In fact, according to Albert Einstein's famous equation, E = mc² , time travel is possible, at least in one direction.
The laws of physics prohibit traveling backwards in time for many reasons. If we did travel backwards in time and changed the course of events, we would be altering the course of history.
The model, called Mindy, provides a terrifying glimpse at what people could look like in 800 years if our love of technology continues. According to the company, humans in the year 3000 could have a hunched back, wide neck, clawed hand from texting and a second set of eyelids.
According to a US report, the sea level will increase by 2050. Due to which many cities and islands situated on the shores of the sea will get absorbed in the water. By 2050, 50% of jobs will also be lost because robots will be doing most of the work at that time. Let us tell you that 2050 will be a challenge to death.
In the next 1,000 years, the amount of languages spoken on the planet are set to seriously diminish, and all that extra heat and UV radiation could see darker skin become an evolutionary advantage. And we're all set to get a whole lot taller and thinner, if we want to survive, that is.
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.
Constant Speed
So what does this sentence really mean? Surprisingly, the answer has nothing to do with the actual speed of light, which is 300,000 kilometers per second (186,000 miles per second) through the "vacuum" of empty space.
What does E = mc^2 mean? One of the most famous and well-known equations in all of human history, E = mc^2, translates to "energy is equal to mass times the speed of light squared." In other words, wrote PBS Nova, energy (E) and mass (m) are interchangeable. They are, in fact, just different forms of the same thing.
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).
NASA's James Webb Space Telescope is often called a “time machine.”
Although humans can't hop into a time machine and go back in time, we do know that clocks on airplanes and satellites travel at a different speed than those on Earth. We all travel in time! We travel one year in time between birthdays, for example.
Based on our current understanding of physics and the limits of the natural world, the answer, sadly, is no. According to Albert Einstein's theory of special relativity, summarized by the famous equation E=mc2, the speed of light (c) is something like a cosmic speed limit that cannot be surpassed.
As you might expect, the possibility of time travel involves those most extreme objects, black holes. And since Einstein's theory is a theory of space and time, it should be no surprise that black holes offer, in principle, a way to travel through space, as well as through time. A simple black hole won't do, though.
In the Back to the Future franchise, the DeLorean time machine is a time travel device made by retrofitting a DMC DeLorean vehicle with a flux capacitor, which allows for time travel when it hits 88 miles per hour.
