# Is it really possible?

Hi, I'm looking at recently in the forum, but can not find answers to a question that haunts me since I was little, that is: you can travel in time today? If so, how?

Yes , it is possible but for negligible duration , by using Einsteins genral theory of relativity .

Time travel is already done by a Russian astronomer , but for very less time .

Serial ISS resident Sergei Krikalev holds the record for the longest amount of time spent in space with 803 days, 9 hours, 39 minutes under his belt.

The ISS travels at around 7.66 km/s when orbiting around Earth, and due to the high speed and length of time which he spent in space, the cosmonaut actually arrived back in Earth 0.02 seconds in the future by using process known as time dilation.

Thank you for the answer. In your opinion is possible increase the time of the travel?

Yes off course , it all depends on speed . How close we can get to the speed of light .

This table shows the time dilation at percentage of speed of light .

It says that if we travel at 50 % of speed of light , time dilation for us will be 86.6% . That means for every 100 seconds passed for stationary people , time will pass 86.6 seconds for us , and we will travel 13.4 seconds In future .

Using this theory , we can travel considerable amount of time by increasing our speed .

Well, excuse my insistence, but i think that we can't get very close to the speed of light currently, so is possible take a time travel without reaching the speed of light?

By gravitational time dilation .

Satellites regularly travel time because of there speeds and the gravity in which they are moving .

As gravity increase time slows down .

Fact is that we can't achieve considerable time travel by the technology and theory we have .

Thank you

Final answer, yes. Whether you say time dilation making you .002 seconds into the future or applied and theoretical physics. You can travel in time today, the theorems do work out there are ways to, the problem hers is out technology, our metals, our computers et cetra. To the future travel at speed of light, to the past, tipler cylinder. But the technology to move at light speed or to open a pocket dimension is above that which we have no, thus the need for quantum computing.

It is not answer- needs just 2 gigawatt of electricity and everything attached.

To decode subject is very simple. Imagine that time machine is black box.

We have a few ways to build time machine. Taking one way that able at present time and build a prototype. Experience will give another thoughts.

Implementing new ideas in new prototype will move us forward.

Please explain more , so that it will be easy to understand for people like me . ☺

Needs money to start experimentation.

Otherwise needs a lot of time to speak,to speak, and speak on this forum or another one.

Would you say it is possible to travel to the past?

Till now no theory is available which proves that travelling to past is possible .

Or I never goes through such theory .

If you or anyone knows any good theory about how to travel past , please share ?

Most scientists believe it impossible to time travel backward in time, while proponents of the many worlds interpretation suppose people might move back or forward in alternate timelines. Even so, I knew a woman with a photographic memory, which is rarer than people are led to believe, who believed her memories cellular, i.e. literally those of her great, great grandparents whom were expert in similar branches of science.

It was her genealogist cousin who revealed her predecessors a herbalist and botanist. Thus, owing to now extinct plant species, I can but wonder at her seemingly firsthand knowledge.

if we are able to get incredibly above the speed of light, i think we can travel to the past

@rishivashista13, I am agree with you. Thanks for sharing suggestion.

That I was also thinking about ,But as we getting close to speed of light our mass will increase rapidly and further more energy given for increase speed will be utilized for increase mass , and by that way we can't reach speed of light.

That I was taught in school .
