No kidding, most esoteric teachings and religions come to the conclusion that when we die, we just get rid of our physical body. Then it is separated from other bodies (the astral body and others, there are 7 of them, as far as I remember). In short, we are returning to our incomprehensible beginning. Then again, a particle from this common principle is introduced into a new body. But this is not always so, also the soul can go to higher levels of knowledge. Therefore, I think reincarnation is the most rational conclusion. The energy is infinite, the soul cannot just disappear (lose its potential).
Even stars appear to have limited lifespan, and (this) universe which appears to be in an expansion phase. But the time periods involved are so huge, its like asking an ant about human lifetime. It might just not be possible for a sentient race to ever answer this question during is blink of existence on a cosmic timescale. What IS this cosmos anyway? Where it came from, where it will go. Big bang what was it? How it came to exist? Its kinda known as the "singularity" that gave birth to (this) universe, but is that all there is? Where did these matter came from and how it got started? Some speculate it is an endless cycle of expansion contraction, but the only thing observable now is expansion that is accelerating.
Do not underestimate thinking either, its not a "complete waste of time". Ask you this question, how could Einstein possibly have found that time was relative? Its not like he had the super precise clocks of today, or spaceships to do measurements with (his theory were only confirmed after humans went into orbit: set two identical clocks observe them remain in sync for a year on Earth, then give one to an Astronaut for a mission weeks or months long; when he returns back his would appear to be late, or "slowed down").
You cannot perceive it, but even the time for someone in the street is a very tiny bit different to someone on the top of the Empire State, this is because things are moving relatively slower close to the ground.
How could possibly someone in the early 20ieth century could possibly correctly guess this? People say "genius" now, but what was it back then? He didn't even live to see that confirmed...
General relativity (GR), also known as the general theory of relativity or (GTR), is the geometric theory of gravitation published by Albert Einstein in 1915 and the current description of gravitation in modern physics. General relativity generalizes special relativity and refines Newton's law of universal gravitation, providing a unified description of gravity as a geometric property of space and time, or spacetime. In particular, the curvature of spacetime is directly related to the energy and momentum of whatever matter and radiation are present. The relation is specified by the Einstein field equations, a system of partial differential equations.
How did he came up with it in 1915? Cosmic revelation? Why would the cosmos bother to reveal rocket flight to an ant? Human imagination? But humans imagine all sort of nonsense all the time, why would this be correct, pure randomness? A broken clock always point the correct hour twice a day? Could there be truths in various spiritual disciplines waiting, but unable to be proved within our lifetimes, or that of our species, even tho they may actually be the truth (or not)?
Seriously stop to think when someone in 1915 tells you your time is different to mine if you are traveling faster. And it was true, the discovered one of the "hidden" laws of this universe, a Jew!
Couldn't the prophets and wise people of the past somehow "guessed" some things correctly? You know this "Atom" word actually comes from ancient Greece? It turned out "atoms" were not the smallest particle as originally predicted, actually we probably assigned the name too early, before discovering the "sub-atoms" that form them but there happens to be a smallest indivisible particle that only contains energy, a "mysterious" thing that keeps it in motion (and our bodies are built on those, go figure).
Where do the babies get their "programming" from? We know a couple exchanges genetic material, and some "traits" get inherited, but for the most part, this person's "soul" or whatever it is that makes someone do certain things and not certain others, come from.
Asexual reproduction actually doesn't even exchange genetic material, but it still forms a "being" that is not his source. A clone made of you, is NOT you, even it if looks identical to you, it is another being. Because of taboo this hasn't been observed much yet, but eventually it will. Corals do this in nature, by the way. They have the choice of asexual reproduction to growth its population, but its homogeneous offspring could all potentially be weak by single type of, so encountering another coral and exchanging genes is preferred "just in case" (to deliver its species from extinction).
Contrary to what some people believe, the spiritual and scientific paths are not necessarily antagonist, in some things they are, but in many others they share position. Again, someone like Einstein could easily been declared a prophet in the past (or a heretic and burned at the stake). You wouldn't believe how the ancient Romans viewed the universe. There is
a book that survived the ages (and the church, etc) its about architecture. Try to read it, its incredible, like a time machine, a look 2000 years into the past, dedicated to Caesar Augustus no less. Some of the things are nonsense, some do make sense within their (limited) cosmic vision of things, and some are incredible approximation to what would only be discovered (or confirmed by science) thousands of years later. Aren't we limited to ours? Surely will be said, 2000 years from now, if humans still exist then.
