In the future, time travel will certainly be possible. But many people may wonder, if that's true, then why don't we see people in the future world return to the present world? This question is a question for people who misunderstand time because time can stretch or shrink but cannot be reversed. Therefore, time travel is only possible by traveling forward. Which is possible in 2 forms, 1. Abbreviation time and 2. Stretch time. 

      1. Abbreviation time : This type of travel is to travel to the future in less travel time than earthly time. for example It's the year 2023. Earth's time normally takes a year to travel to the year 2024. But you travel to the year 2024 in just 1 day, 1 hour, or less, etc.

   2\. Stretch time : This type of travel is to travel to the future in a much longer travel time than ordinary Earth time. for example It's the year 2023. Earth's time normally takes 1 year to travel to 2024, but you travel to 2024 and it takes longer, like 5 or 10 or more, etc

   I believe that time travel in these two forms can actually happen in the future.
