Is Time Travel Possible? Science Says Yes

We as a whole travel in Time. We travel one year in time between birthdays, for instance. What’s more, we are altogether going in time at around a similar speed: 1 second per second. 

NASA’s space telescopes likewise give us an approach to look back in time. Telescopes help us see stars and galaxies that are exceptionally far away. It requires some time investment for the light from distant galaxies to contact us. Along these lines, when we observe the sky with a telescope, we are seeing what those stars and galaxies looked like a very long ago. 

Notwithstanding, when we think about the phrase “time travel,” we are normally considering voyaging quicker than 1 second per second. That sort of time travel seems like something you’d just find in films or sci-fi books. Could it be genuine? Science claims yes!

How would we realize that time travel is possible? 

Over 100 years back, a renowned researcher named Albert Einstein thought of an idea regarding how time functions. He called it relativity. This hypothesis says that time and space are connected together. Einstein likewise said our universe has a speed limit: nothing can travel quicker than the speed of light (186,000 miles for every second).

What actually does this mean for time travel? Indeed, as per this hypothesis, the quicker you travel, the more slow you experience time. Researchers have done a few analyses to show that this is valid. 

For instance, there was an experiment that picked two clocks to precisely the same time. One clock remained on Earth, while the other flew in a plane. 

After the plane flew the world over, researchers analyzed the two clocks. The clock on the quick plane was marginally behind the clock on the ground. Along these lines, the clock on the plane was voyaging somewhat more slow in time than 1 second of the second. 

Would we be able to utilize time travel in regular daily existence? 

We can’t utilize a time machine to travel many years into the past or future. That sort of time travel just occurs in books and animated pictures. In any case, the math of time travel influences the things we utilize each day. 

For instance, we use GPS satellites to help us sort out some way to get to new places. NASA researchers likewise utilize a high-exactness adaptation of GPS to monitor where satellites are in space. However, did you realize that GPS depends on time-travel estimations to assist you get around town? 

GPS satellites orbit around Earth rapidly at around 8,700 miles (14,000 kilometers) every hour. This gets GPS satellite tickers slow-down by a little fraction of a second. 

Nonetheless, the satellites are likewise orbiting Earth around 12,550 miles (20,200 km) over the surface. This really accelerates GPS satellite clocks by a slighter bigger fraction of a second. 

Here’s how: Einstein’s theory also says that gravity curves space and time, causing the passage of time to slow down. High up where the satellites orbit, Earth’s gravity is much weaker. This causes the clocks on GPS satellites to run faster than clocks on the ground.

The joined outcome is that the clocks on GPS satellites experience time at a rate marginally quicker than 1 second per second. Fortunately, researchers can utilize math to address these differences in time. 

If researchers didn’t rectify the GPS clocks, there would be large issues. GPS satellites wouldn’t have the option to effectively compute their position or yours. The blunders would amount to a couple of miles every day, which is serious. GPS guides may think your house is not even close to where it really is! 

Conclusion:

Truly, time travel is undoubtedly a genuine thing. However, it’s not exactly what you’ve presumably found in the animated pictures. Under specific conditions, it is conceivable to encounter time travelling at an unexpected rate in comparison to 1 second per second. Also, there are significant reasons why we need to comprehend this genuine type of time travel.
