Time travel is the ultimate challenge for humans as of now. But is it possible ??
Here is what people think :
"Time travel is possible
"Time Travel Can Exist
The current model for a time machine is a device called an Alcubierre Drive. An Alcubierre Drive allows a spacecraft to contract space-time in front of it, and expand space-time behind it, essentially making it a time machine. A recent ABC report states that NASA is currently working on the possibility of an Alcubierre Drive, and some NASA physicists believe that an Alcubierre Drive could indeed exist given superior technology.
In a few hundred years, when technology and our understanding of the universe expands, time travel will become possible."
"If time travel exists then delete my post.
Let this message be forever preserved until technology to travel back in time has been developed. Then let someone come back and delete this post. So if you are seeing this post traveling back in time will never exist."
