<p>Can ppl create time machine? I think they can't.</p>
<p>I wish I had a time machine so I didn’t have to read this post…</p>
<p>i heard you can, but you gotta travel faster than the speed of light…</p>
<p>but if in the future they can create a time machine! So, there must be a man from future here</p>
<p>It’s called a paradox, i.e. [Grandfather</a> paradox - Wikipedia, the free encyclopedia](<a href=“http://en.wikipedia.org/wiki/Grandfather_paradox]Grandfather”>Temporal paradox - Wikipedia)</p>
<ol>
<li>You’ve got to reach the speed of light (HIGHLY improbable). Heck, if something moves at that speed, the time travel will be of no use. It’s not so sure what exactly will happen to the thing that moves at such a fast speed, but the predictions aren’t too…let’s just say “comfy”.</li>
<li>It’s not what movies project : Go back to [Enter random past date]</li>
<li>All it will do is reduce the real time of the particle moving at the speed of light. So that particle’s one second won’t be equal to our one second. Thus, if it’s a human being moving at that speed, he/she will age slower. Cool way to stop wrinkles, right?</li>
</ol>
<p>and here i thought this was about the application in snow leopard called “time machine”</p>
<p>…</p>
<p>People have actually held conventions to invite people from the future, but nothing great happened.</p>
<p>Umm of course it’s possible. Hello, haven’t you seen Back to the Future? 
Right up there with hover boards (always wanted one of these). </p>
<p>Don’t worry, I’ll make a time machine for my senior thesis :D. Either that or make a dinosaur. One or the other.</p>
<p>Haha well we never know what the future holds.</p>
<p>The grandfather paradox doesn’t have to occur if we consider the possibility of alternate realities, or other universes similar to our own. There can be an infinite amount of these universes, and they contain all the possible combinations of reality(diff. laws of physics, scenarios, etc.) including universes exactly like our own except they’re further back in time than us. All we’d have to do then is cross dimensions(other than our current four) to access those types of universes, and we’d be technically back in time.</p>
<p>Building a time machine then would simply be a matter of constructing a machine that would allow us to cross dimensions and, thus, travel between universes.</p>
<p>Edit: What federernadal is describing is time dilation btw, and it’s completely real.</p>
<p>it must be some kind of…hot.tub.time.machine.</p>
