Open this thread and have your mind blown.

So what you telling me is you believe in aliens?

Actually, every photon arriving at your retinas is from a different time. We don't distinguish between, say, a photon traveling a mile from one coming from a hundred meters away because the time difference is too small.

If we received a message tomorrow from another civilization, chances are that civilization has been extinct for a very long time. That's why it practically doesn't matter if there is life out there or not.

That's not entirely true since you're only accounting for the ways we know how to communicate and not what they're communicating with.

In quantum nonlocality, entangled particles exchange information over any distance instantly. Experiments have observed this phenomenon. Things are strange at the quantum level.

True...but how would we respond back. That's be like sending an email to someone who can only send something back via Pony Express.

As in Contact, hopefully the alien civilization would include instructions for building a machine to communicate with them.

Everyone knows that if a planet that is inhabited 64M light years away were to look at earth from their planet they would be viewing a planet populated by dinosaurs.

When you look into the sky at night and see those thousands and thousands of stars, they're coming from different light years of distances all to hit your eye at the same time. You're looking at thousands and thousands of completely different times from the past all smashed together and patched together to be viewed at one time.

If you really want your mind blown consider this ...

Okay, so since light travels at 186 miles per second - everything you're seeing out there, you are actually looking back in time - correct. You seem to have a shallow grasp of that concept, but I'll accept it as it is FWIW.

To put it into perspective, the sunlight we see each day, from our star, the sun ... it took eight minutes to arrive here, to our planet, traveling at 186k miles per second.

Okay, with all of that understood now imagine something with enough gravitational force to warp the space/time multidimensional plane and create a "wormhole" between two planes which could be traversed so that, theoretically, we could travel-through said "wormhole" from one side of the universe to the other.

Okay, okay, you with me so far?

But did you know the whole theory of "wormholes" was postulated some 100 years ago and, back then, it was more commonly referred to as the Einstein-Rosen bridge. Yet, even 100 years ago it was understood, as it remains today, that there is no known power source that could connect the two planes long enjough to travel=through.

So here's the deal.

Where we need to concentrate our efforts, if we wish to travel the universe, is on power. Power far greater than even harnessing our medium sized star. A star, btw, which we have yet to harness (we are still a very primitive species in terms of harnessing power, which is how species would be judged on a universal scale) even a fraction of it's full potential. (More energy from the sun hits Earth every hour than the planet uses in a year.)

My point being, if you want your mind really blown, is that, until we learn to master the available power in our immediate solar system, we have absolute zero chance of traveling to other stars.

UNLESS, unless, we are gifted the knowledge from another species ...

OR ... unless our future species travels back in time and grants us the knowledge from our future.

Now, think about that.

That's a conventional way of looking for a solution. Another way might be to understand how quantum nonlocality could be translated to the macro world. After all, everything is made up of the same sub-atomic particles. Imagine being able to jump to any place in the Universe instantly.

---

... with regard to the macro world, once we positively identify dark matter and learn how to harness it, or even negative matter, (if they are not one in the same), then we might begin to have a better understanding of things on the quantum level.

Yeah, I've often thought that particles that "wink in and out of existence" could very well be transitioning between matter and anti-matter (possibly known as Dark Matter) states.

Dark Matter could also be the long-sought WIMPS, or weakly interacting massive particles. DM particles would almost have to be massive to explain the amount of gravity they're responsible for.

Whatever Dark Matter turns out to be, or for that matter Dark Energy and Gravity, I think our existence will be dramatically altered if and when we learn to use it to our advantage.

---

No doubt ... one way or the other, our existence will be dramatically altered when it is discovered and we try putting it to use.

All it'll take is one little screw-up and BANG, it's all over but the cryin'.

Which brings to mind the other mind-blower in all of this and that being that at the instant of creation, as we know it the Big Bang, the battle between matter and anti-matter being won (barely) by matter which now encompasses all the matter we are currently able to see in our universe.
