Comment on Why are people from the future not time traveling to our period? (2012)

Time is not a universal component, it is a measurement.

Time is a tool we use in order to understand now. Only now exists, nothing else does. No past. No Future. Only now.

Until science embraces this simple truth, all of the compiled understanding we've accumulated will be flawed.

Time is a rock splashing in the pond. The rock exists, and the pond exists. The ripples are mere effects of the rock meeting the water. They do not exist as entities of themselves, they are representations of the action between rock and pond. There is only now. There is only rock-and-pond.

There can be no action/reaction without time. If there is no past and no future, there is no cause and effect, so everything is either pre-ordained (odd) or it just 'is' in a completely trivial sense.

The past is a collection of "nows" that did exist. The future is a collection of "nows" that will exist. But this now is the only one that exists. Recording and remembering the past ("nows" that did exist, but no longer do) helps us predict the future ("nows" which do no yet exist, but will.) Energy cannot move across distance instantly, so we have the concept of "time" to allow us to remember where the energy started and predict where it will go.

But only now exists. You can't go skipping off into the future because it's not there. Neither is the past anywhere that can be visited. Only now is.

Just because now is a reaction to the past doesn't mean that the way it is was inevitable. Whether you believe in free will or fundamental randomness, absolute determinism is untenable.
