Thanks for all the replies. I think I get the point but may be back later.

Hi, I hope someone can explain where my reasoning is wrong. The faster something travels relative to an observer, the slower time passes for the moving entity. Taking this to what appears to me as a logical conclusion... If I, the observer, see light from Sirius; since it is travelling at the speed of light, the light should arrive instantly since no time would have passed, disagreeing with the light from Sirius taking ~ 8.6 years to reach my eyes on Earth.
