Whao, all of this are new information. thanks they help a lot=D
But one more question, if time is (space ,other dimensions that things travel to one direction.), What is before time? If time is what is mention, anything that happen before that should not even happen. Hence if that did not happen how does time even start?

Since time is an evolution parameter, as said above. Asking «what is before y?» is like asking for some x(t) given y(t') where t<t'. Your question «What is before time?» is like asking for some x(t) given t where t<t, which makes no sense.

Hello all,

I would agree that dx/dy does not require time since the infinite number of possible ratios are all contained at ounce in this simple equation.

For me, Time is very real and is defined as the infinite realm in which space exists... it is the space of space and their common existence is spacetime.

In spacetime, Time enables fundamental energetic processes to evolve in space, interacting and becoming each and every structures we have so far named and included in the comprehension we developped of our magnificent Universe.

Our best (and current) comprehension culminates in Science and, since the beginning of its endeavour, Science uses Time in a quantitative manner providing a measure of duration that is usable in itself or in a relative way.

The actual quantization of Time is a product of basic arithmetics; 1 + 1 + 1... the accuracy to which it is measured depends on our current mastery of how fast we can resolve this basic repetitive addition.

For the human mind, Time remains a representation of duration, perceived in a mental creation stemming from both our environment, which itself is in a vast array of relative motion, and our knowledge of that basic arithmetic operation.


regards,

VE
 
It's the thing that keeps everything from happening all at once.
 
It's not a dimension per say. It's an unconstant constant constant.
 
The OP's second post had an interesting question. When the universe was the size of a pin-head (or smaller), before expansion, shouldn't 'time' be frozen due to gravitational time dilation?
 
Previous thread on this very issue has either been deleted or locked, due to several violations of the PF Rules, especially on speculative posts.

It looks like this thread will suffer the SAME fate. We have given it ample opportunity for people to discuss this on the basis of valid physics. However, it has now meander into personal opinions, speculation, and philosophy. That signifies the end of this thread.
