h2g2 The Hitchhiker's Guide to the Galaxy: Earth Edition

Have you ever come to the idea of how small we really are. And since the fourth dimention exists, nothing's perfect. Including humankind.
I think stars are bugger than us.

As the universe is endless, everything conceivably should be possible. Also alien life on other planets. It will probably be very differend from us, humans. And we can't even guess whether these aliens are more evolved or not. We even don't know if they have evolved along lines similar to ours. It is well possible they don't know anything about radio, but use telepathy or brainwaves. They also could have developed a quiet differend technology. So perhaps ESA should start looking at other possible ways of communication. Already laser light seems to be an option, but I don't know how far this possibility has been developed. Anyone?

Sorry, I mistakenly wrote Esa instead of Seti. Sorry for that!!

yeah, anything but radiowaves. They are just too slow. I don't know much about these lasers you mentioned. Perhaps we should research a little

Radiowaves are travelling with the speed of light, so that is ok. But I haven't a clue whether brain waves or telepathy are traveling at the same speed, if this kind of waves exist at all. Has there ever been any study on this subject and what do we know about it?

The speed of light is not fast enogh (see, the nearest star is 14 ly. from us. That's terrible if we want to communicate large. Research? Of course - all the time. But for now nothing can move faster tan light. Poo

Sorry, but there is nothing going faster than light. So you will have to invent something or find a way to go faster. Time travel also would follow the same principle.

What makes you think time travel is possibe?

Time travel would only be possible if you can travel faster than the speed of light.

Which you can't.

I don't get it. the speed over the light speed is called "time travel"? It's ok if that has nothing to do with defying time as we lnow it. I mean, time seems to be the only thing we humans cannot beat it..if you get what i mean

The speed of light is not the same as time travel. The one has nothing to do with the other. So it makes no sense to say time travel should go faster than light. The speed of light is something that is measured and "proven" to be in accordance with Einstein's theory.
Time travel is hypothetical and not proven at all. People ask themselves :"what would happen IF we could move back or forward in time?". And next one can speculate about it. That is all.

Bit of a pity then that Professor Paul Davies, the Australian theoretical physicist from Macquarie University, believes that he can prove the speed of light has actually slowed down over time. So much for our accepted laws of physics and our understanding of the beginning of the universe. Judging from the report on their website, NASA certainly seem to be taking him seriously too.

Such things are not a problem for modern theories. As long as we don't know which mechanisms are responsible for the respective value of the speed of light, no sentence in the textbooks needs to be changed; only some to be added.

Light was slower initially, they say, but that does not mean something can go faster than light.

Sorry, I made a mistake. Light was going faster and in the course of billions of years seems to have slowed down. But still, Light is the fastest thing in the universe, unless proven diferently...

there must be a carbone-based creatures affected differently in terms of time and light. I mean, they... uh, foret it. I was thinking of how far from this issue are we humans. I should blame the cancer thing I'm born under it. Too much pressure on me, people!

There is a science fiction book by Robert A Heinlein based on the idea that telepathy would allow instantaneous conversation between different solar systems. The title is Time for the Stars. It's really good.

The nearist star, Proxima Centauri is four point something ly away. THe alpha centauri system is under 5 ly. Even sirius is only about 10 ly away.

yeah, telepathy! It'd be good if somebody could teach me that ;]
the book might be good only our best chances are no further than its frame... if you get what I mean

light is the fastest thing we know,so far, just wait til science find the real fastest thing
can we be open to other ideas?
