time

What is the purpose of money?/What money does, who is good at making it, and who is a Hi all, I have the following argument regarding the purpose of money, does it seem correct to you, or am I wrong in my reasoning? All feedback welcome, but please, keep it classy.:D What is the purpose of...

The concept of time. I'm thoroughly confused by it. I don't claim to know much about it at all, and it's a concept I cannot get my head around. I've read about time dilation, different dimensions, and other physics related topics and while I can sort of grasp them, there comes a point where I...

I suggest that in pure empty space, devoid of mass or gravity, that the Flow of Time is infinite. Time stops at the speed of light, it will nearly stop for a mass traveling very close to the speed of light. When a gravitational field strength decreases, time flow increases. It has always been...

http://www.technologyreview.com/blog/arxiv/26992/ I am really confused by the above article. From a brief read through, they're saying that by slowing down light and then speeding it back up, we can effectively hide something in time for about 110 nanoseconds. Is this correct? Does that mean...

"The concept of time as a way to measure the duration of events is not only deeply intuitive, it also plays an important role in our mathematical descriptions of physical systems. For instance, we define an object’s speed as its displacement per a given time. But some researchers theorize that...

This is perhaps related to the "hard problem of consciousness" in another forum, but I come to it from science, rather than philosophy. (Actually, it was long ago article in Scientific American which brought this to my attention). And that thread is very long and convoluted, and often quite...

A question for those who know a lot more about physics, cosmology and philosophy than I do. I'm engaged in a discussion on another forum, and the topic has drifted to the idea of causality. My erstwhile opponent (who is a religious moderate with fundamental leanings, if that makes any sense -...

Hi everyone. This is my first post, although I have been reading certain threads every now and then - and even though I am not an active skeptic when it comes to organizations et cetera, I try to follow the skeptic world as closely as I can and would consider myself skeptic by heart. Anyway...

One more thread for the road. Dang, I'm on a roll today. So. As far as we know, matter and energy can't just appear out of nowhere and nothing. Where, then, did the universe come from? Answer: It always existed, for an eternity in the reverse direction of time. Removed hotlinked image...

I was just wondering whether time is a sort of Heraclitian 'continuous flux' or whether it's quantised into distinct units. I realise these may be the wrong terms to use. Basically, is there a generally accepted physical view of time which deals with this old distinction?

Question One - Various answers have been given, as to why Gravity is able to excape from a black hole - but none have addressed the fact that gravity has now been shown to travel at speed c. Question Two At speed c, time has dilated to zero - Therefore, from light's frame of reference...
