@Frank Apisa,
Quote:I do not know the true nature of the REALITY of existence, Carlos.
Do you?
OK.
Lets go to basics.
We are organic compounds formed by particles; particles are former by atoms; atoms are former by protons neutrons, electrons; electrons are assumed to be composed by smaller
objective components or parts.
Whatever is the primeval component of matter and energy, if it is perceived by our senses and instruments, then it is physically real.
What is "now", "past" and "future"?
I will explain it with the most accurate definition in base of
facts, solely facts. In base of the rule of
THE PERCEPTIONAL LAW we can obtain the following:
We have particles in the universe causing the existence of matter and the existence or recycling of energy.
The universe is in
continued motion
Here is the key:
motion
Motion rules the universe. Nothing is found without motion.
We perceive motion, we see objects and celestial bodies in motion continually. In base of our perception of motion, we have invented a measure called
time
From here, in base of this perception of
motion we have established that
1)- when the motion of an object or body has passed to another step/status or place (decaying, moving, etc.) we call to the former step/status or place, the
past, and
2)-when we think or calculate that the motion of the object or body will pass into another step/status or place (growing, moving, etc.) we call to this next step/status or place, the
future.
There is no more to add to this simple perception of the universe. If some weird behavior of motion is perceived, it will be always related to matter and energy and motion. Nothing more.
You might argue that other possible existence is anti-matter and similar, but if anti-matter affects the behavior of matter, then anti-matter is physically real. Keep in mind that "we call it" anti-matter, but actually we have no idea what it is. Still, the observed phenomenon in tests show clearly that is physically real when affects matter.
We might don't understand the universe in its whole, but as far as we can perceive it (with or without explanation to what we perceive, how we perceive it, etc.), then we can recognize physical reality.
You don't need to fully understand how lightning happens, but you can perceive it and you know that it exists not only by the fraction of a second spark, but also by the damage that it might cause to houses, trees, etc.
The same as well, we recognize as "now" to the continued observation of the continued universal motion both in parallel.
We can't see the past at all: even when you watch the video of a terror attack, you are watching the current images coming from inside a device, but the physical terror attack happened two days ago and neither you nor anyone trillions of miles far away from earth will see it after two days, because the past doesn't exist anymore:
the atoms of the particles of the molecules of the organic compounds forming the human bodies who performed the terror attack have moved already, and are now somewhere else: on the run, killed by police officers, etc.
THE PERCEPTIONAL LAW is the best tool to understand physical reality and comprehend the meaning of
past, present/now and
future.
