Thank you Nugatory, it's a very good point that you have made here and if other contributors from this thread are reading I want to pass on a thankyou to all of them also. Although I feel like my original statement and idea still stands up and is important I have learnt a lot from reading all...

then tell me, why does it take infinite energy to travel at light speed - approx 300000km/s?

yes, they gain mass as they approach the speed of light, time also slows down for that object. my original point was that light speed is an infinite speed, if that were so it would take an infinite amount of energy to accelerate to that speed and any distance would be arrived at instantaneously...

why can you not accelerate anything to the speed of light Dave? please elaborate. [Mentors' note: this post has been edited in an effort to keep the discussion in this thread focused on the physics]

Perok Perok when you say 'the physical consequences are well understood' you leave your point there, i would like you to go on. Also you say popular science isn't satisfied with things that cannot be defined but why should they be, this is after all an attempt at understanding the physical...

Thanks Perok, Thanks Perok, I appreciate what you've done here. Co-ordinate time and Proper time are the terms I should have been using - thankyou Ibix also.

isn't that so interesting phinds, it never existed in time and yet it also at a measurable finite speed (speed of course = distance over time), it's another duality of light

Hey Dale thanks again, what I meant was if something accelerated up to the speed of light (I know that is physically impossible (but isn't that because light speed is also an infinite speed as I was saying) then at that moment time would cease to exist for that object. I see your point Dale if...

thanks FactChecker, I only used the true and apparent analogy to describe that something can be at two speeds simultaneously, it is just a metaphor and not the message. The message that I want to put forward here is that light has an infinite and a finite speed and qualities associated with...

I forgot to add thanks Dale

yes Im not trying to anthropomorphize light, I know that wouldn't make sense. Im just talking about time ceasing to exist for something traveling at the speed of light (theoretically).

hello I enjoy pondering ideas about life and the universe but it gets lonely just thinking by yourself and sometimes it feels like ideas need to be tested by a group or given up to a group to be pondered over by others. So hopefully I can contribute something interesting of my own as well as...

hello, I am interested in the speed of light as well as electromagnetism. I understand that time stops at the speed of light, which is approx 300000km/s. but because time stops at the speed of light it appears to me to have two speeds- those being the speed it experiences which is...
