Once I read that, due to evolution and climatic change, the human beings of the future will be small, hairless and pale, because the sun will be so strong that the new generations will be living under artificial light. One day I was talking about travelling through time with a friend, and I told her that if this was possible, people from the future would be visiting us. Now I started to think: could it be possible that our typical aliens with white bold heads are just the future human generations visiting us? Just a thought that came to my head...

interesting theories!! however, I think it'll take at least 1 billion years for the sun to intensify by as little as 10% --- and since modern man is only about 100 thousand years old, I think man will have evolved to such an extent by then, we wouldn't even recognize them as having "human" origins...

I like your idea about "aliens" being, in fact, future humans. In a way, it would make a lot of sense. Considering the insanely massive size of the Universe, why would distant alien societies be interested in a tiny ant-hill speck like Earth? Future humans would be far more likely to desire revisiting their roots.

that would have worked if you hadn't stopped me

The idea was originally advocated by Micael Crichton, aka. "The Seti-Traitor", in one of his books.

But, alas. Timetravell is a bit of a no-go since the law of conservation of information put's an early and brutal stop to it because the bits of the "future" or the "past" that you would suposedly try to move into what we percive as "now" will be blocked out of the reason that the "bit-oportunities" are already ocupied by the "now-bits".
For those who want to understand this in a deeper sense of the meaning will have to read Digital Mechanics by Edward Fredkin. If I tried to explain it I would probably use way to much logmath. At least take a quick look at the law of conservation of information and six-phase time.

You can download the book from Fredkins homepage. It is actually quite mind-boggling once you get past the strangeness of the concepts. Just imagine the abillity to simulate things into being...

How about a link M8 ?

Thanks for that. :-D

Or for a bit of a shorter explanation.

Short guide to a strange Universe!

A note on the Sun issue:

Perhaps it is a loss of Earth's atmosphere, rather than the intensity of the Sun itself, causing the problems for future Civ's.

"Be who you are and say what you feel, because those who mind don't matter and those who matter don't mind." - Dr. Seuss

I've thought about this before, but from my understanding of current theories of backward time-travel, going back into the past would send you not into your _own_ past, but a parallel Universe (where you pop into existence at a time when you didn't exist in your original timeline).

This would mean that getting back to the future you know would be impossible, as it would be the future of that new timeline; and due to the "Butterfly Effect" (started by you simply existing) it would likely be a very differnt future.

Is this idea of time-travel wrong, and if not, why would time-travelers travel into the past to study us when they could never go home to report?

Eh, food for thought...

Perhaps that theory is wrong.

It makes good sci-fi, but the problem with that theory (or any theory "explaining" so-called extraterrestrial visitors) is that there is no credible evidence that the Earth has ever been visited by intelligent beings from another world.

I hate to be the one that throws cold water into the fire, but...

Worse, much of the so-called "evidence" depicts beings that reflect popular culture icons of the time that they emerged. These so-called visitors have taken many forms over the decades and the only thing that they seem to have in common is the ability to blur the photograph being taken of them.

As for the XFile-ish "The Truth Is Out There" conspiracy theories that the gub'mints are "hiding the truth": governments can barely handle delivering the mail. Politicians can't even get away with hiding their most intimate secrets. They can't even get away with hiding bribe money in their personal freezers. To say that they are capable of such elaborate conspiracies is an undeserved compliment upon them.

My gut feeling is that we will never, physically, come into contact with intelligent beings of another world. This is probably typical of the cosmos: intelligent beings of different worlds are physically incubated from one another through space and time.

The SETI projects are the best (current) chance we have of finding an (ancient) intelligent intelligence. Even then, only if we get lucky. Really lucky. The odds are probably on par with winning the lottery a hundred times in a row.

Edit: This isn't to say that I don't want to believe that any of the SETI projects will be successful. Of course, I do, or I wouldn't be here. At the same time, however, you do have to be realistic.

The fact that nothing of significance (minus the one time "WOW! Signal", which may have been RFI) has been found over the decades can signify a number of things:

- Intelligent beings more advanced than us are out there, making use of technology similar to what ours is based on, share the same thought process to use the hydrogen line as a beacon, but are very rare. Their technology would have to be more advanced than ours for us to be able to receive their signal. All we can, and will, do is keep searching.

- Intelligent beings more advanced than us are out there, but their technology has completely evolved differently than ours. Unless they have found some sort of holy grail, they would consider the energy required to transmit RF across interstellar distances to be wasteful to produce for that sole purpose. It may not even be possible. Maybe they would use natural sources of high energy carriers to embed their intelligence: such as from gamma ray bursts, pulsars, and quasars.

- We are truly alone or at least the most advanced intelligence around our neck of the woods. (Doubtful!)

In the, relative, near future there is all kinds of wonders still coming. The possibility of finding microbes in the Martian soil, maybe even more complex organisms in the oceans of Europa, the precursors of life on Titan and Enceladus, amino acids out in the Kuiper belt... All cool stuff...

I have all the evidence I need on the website in my signature.

The many out-weigh the few in power.

Do you have any opinion on how time-travel might work?

Not sure, just keeping all avenues open until proven.

It'll take us longer to understand if we assume one theory over another without considering all possiblities.

"Be who you are and say what you feel, because those who mind don't matter and those who matter don't mind." - Dr. Seuss

I had no idea that Crichton had writen about it. In fact, I've never read any of his books... sure, it might look impossible to us and there are many logical explanations that can convince us that it's something out of reach.
I'm not saying I strongly believe on what I said, it was just a thought. What I know for sure is that we shouldn't close ourselves to any new theory, because also centuries ago nobody would have imagined the technology we're enjoying in our daily lives. Maybe our future generations will invent or discover things that are, right now, out of our understanding, things that couldn't be explained with our current technology and knowledge. Anyway, it was just a thread and it was nice to hear all your opinions, I hope nobody took it from the bad side.

Don't worry about us Susana,

We're battle hardened here on these forums.

:)


Your opinions are always welcome and thoughtfully gone over. We appreciate your views and hope to always hear your honest opinions.

Your ideas and input will help us all understand the question and shed light on how to solve it.


Your friends,

The SETI Forum Club :)

Susana, I actually think you're being far too conservative in thinking about what kinds of technologies we might have 100 years from now.

I see some things on the drawing boards that suggest that life in 100, or even 50 years will be completely unimaginable. I think if one of us actually saw (the developed parts) of the world in 100 years, our heads might explode...

Don't worry, I seriously doubt that anyone took offence:-)

I try o stay away from Seti-Traitoring Chrichton too for obvious reasons since it's his fault that there is no official funding for it.

Carl

But since I am the guy who is trying to simulate a carbon atom moving from one point to another and thusly simulacring a real carbon atom to move between the simulated positions, I should probably not be the person to say something is not possible;-)

Anyone who understod me here?
