UFO's and extra-terrestrial life

[TheDawg]

I guy I grew up with- his dad was a B-52 jockey towards the end of the war- the first time a rocket propelled cannon platform came up thru their formation, took out a bomber and vanished, panic does NOT quite cover the hysteria that over took the entire groupe.
After debriefing none of the crews were allowed to talk about it, but they did, initially it was simply assumed the germans had some futuristic buck rogers rocketship type thing, maybe they had a base on the moon, the theorys were wild and speculative to say the least, but we were all doomed, lol.

It all depends. If we live in an infinite universe, then everything that is possible exists so the answer is yes BUT if we live in a finite universe then there is a possiblity that we are alone.

I think that the reason we haven't met haven't met any ET's is that they saw us first and have put us on their ignore list.

Cheers!

There is but one problem pondering the infinite.
We are finite creatures.
Therefore nearly incapable of understanding, let alone relating to the infinite.

All belief systems are reliant on an absence of proof.

Without establishment of truth via all of the five human senses any thought construct can be deemed to be therefore untruth.

See Immanuel Kant's 'Critique of Pure Reason' for reference to the a priori continuance of a particle from second to second.

The universe is demonstrably finite and expanding, for about 13 - 14 billion years.

Although we are finding an abundance of extra-solar planets, many of which reside in the potentially "habitable" zone, we are also learning that there is an increasingly daunting number of factors that must coincide to form life as we have defined it, and exponentially more still for it to evolve even to our point. Even then, with intelligence and technology do they even want to reach out to anyone else?

Black holes don't do anything that breaks the speed of light.

Our universe may be an expanding bubble amongst other bubble universes but even if we could travel to them we'd likely die instantly if physics principles vary even slightly to those defined in the birth of our own.

Perhaps in lieu of traveling faster than the speed of light (even approaching it slows time and increases mass) these "aliens" could bend space-time to get around but good luck with that. Possible, perhaps. Likely, not a chance.

Now, consider the past say, 10 years pretty much everyone and their grandmother has a cellphone with a camera in it. Consider the past 40-50 years since the UFO first became popularized and made us want to be believers. No definitive photos or video. I can understand it being rare but not one video of a craft landing in a field with a big-eyed lanky grey alien stepping out to take a two-stream piss on their way to some Tatooine canteen.

Conclusion: unless you are religiously attracted to the alien phenomenon by faith and ignore logic and statistical data, one has to conclude that alien visitation to this planet is very unlikely.

To each their own but some people with little money and sense, and a faith in things like destiny and fate, love to spend money on lottery tickets as well.

Faster than light not possible?

Try this... imagine a train carriage hurtling along at the speed of light and you are just a passerby watching this.
At the rear of the carriage is a chap who throws a ball to another chap at the front of the carriage; that ball is travelling faster than the speed of light.
As an observer, within the carriage, it would appear that there is just one chap throwing a ball to another chap.

There "relativity" was born

A similar thing can be seen with a carousel and two people at opposite sides throwing a ball to each other. To a viewer on the Carousel, the ball appears to go straight, but, when viewed from above, the ball travels in a curve. (corioli effect)

The Fourth dimension is time and us 3 dimensional criters see the shadow of that as "inside/ outside" (but it is both at the same instant - no beginning, no end)

yeah, imagine you're in the Batmobile with Wonderwoman.. that's pretty much the same grounds in terms of that theory's validity..

Catwoman would get jealous though...

now to the point... when you can't plausably discredit the fact you resort to ridiculing it. Its an age old human trait, indicating a closed mind.
Ridicule it all you want, but you'll never change the fact that the ball has to travel faster than the carriage in order to travel from the rear to front along the carriage's line of travel.

Nope, sorry. Doesn't work like that. For one, as you approach the speed of light your mass becomes infinite. Time will adjust so that the speed of light is never exceeded.

If you are talking relative to another object, sure. a light beam going one way compared to a light beam traveling the other will add up to twice the speed of light but the point is neither in themselves will exceed it. You cannot throw the ball any faster than the speed of light in your example.

The experimental evidence for this is already out there.

According to classical physics, velocities will sum up and you will get more than speed of light. However, according to theory of special relativity, only small velocities can be summed in simply way. Higher velocities must be summed using special formula: .
