is time travel possible

[Gajbhiye_Akash]

<p>According to general theory of relativity gravatational force creats curvature in space-time. time can be slowed down by creating high gravational field . also we can travel back in time by creating closed time like curves . can we use some other force to creat this type of curves .</p><p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; I think that after every sccond a new parallel universe is created . and the universes created after our was created are the backup copies of our past . we can travel back in time or can travel in future by going in those universes . going those universe is like going in 4th dimension . but problem is that the people of universe which was created first can travel in 4th dimension but only in past not in future . </p> <div class="Discussion_UserSignature"> <p><strong><font size="3" color="#0000ff">E=MC^2</font></strong></p><p><strong></strong></p> </div>

I guess it is really cool that you "think" that.&nbsp; Care to explain why ?&nbsp; And what evidence supports your conclusion ?&nbsp; And what evidence do you have that general relativity permits closed time-like curves ?&nbsp; You might also explain how your notion is different from that of Hugh Everett in his Ph.D dissertation from Princeton, under John Archibald Wheeler.&nbsp; And explain why his "many worlds" concept provides exactly the same predictions as does mainstream physics, while yours results in travel backwards and forwards in tiem. <br />Posted by DrRocket[according to general relativity a object with gravity creats curvature in space-time . if a object have very high gravatational field then it can creat a time like loops what do you think<br /><img src="http://sitelife.space.com/ver1.0/Content/images/store/9/0/7943c523-85d7-4c7f-a0dd-34bb2ae07fba.Medium.bmp" alt="" /><br />]<br /> <div class="Discussion_UserSignature"> <p><strong><font size="3" color="#0000ff">E=MC^2</font></strong></p><p><strong></strong></p> </div>
