The time dilation formula:(adsbygoogle = window.adsbygoogle || []).push({});

[tex]\Delta t'=\frac{\Delta t}{\sqrt{1-\frac{v²}{c²}}}[/tex]

says that the closer you come to the speed of light the slower time goes (for the object in movement).

That mean if you travel to a distant star in very high speed, there will take shorter time to get there (for the traveler, not for the observers back at earth) than if you travel at lower speed.

Does that mean that it takes no time at all for light (a photon) to travel from one side of the universe to the other? (for the photon, not us the observers)
