I agree. But we live in a world where politics demands continual growth. If the economy is not growing it becomes a huge issue. In reality we have only been growing our economies on the back of fossil fuels and they are peaking about now. That was my point in saying 2050 will be a very...

"If things start becoming to expensive then we'll innovate round the problem with better recycling, more efficient mining or using a different material for the same job. Eventually Earth could be completely made devoid of resources but I doubt it, even if it did we could harvest elsewhere (at...

This is something I am very interested in. There is something called the Perfect Storm, which appears to be on the horizon. That is the fact that many of the Earth's resources appear to be on the brink; peak oil, peak, water, peak whatever. It does not seem conceivable to me that the Earth's...

About half of them if Vista is any guide.

So we have photons that travel at a speed that we ascertain to be the maximum possible speed in our universe. But for them, although we are not allowed to think of their frame of reference [it is meaningless] time has no meaning and is not experienced. Any attempt to attribute a half-life to...

I chuckle at the "Wikipedia is not reliable" post followed immediately by a post referencing Wikipedia as a proof. Why do not those of you criticising Wikipedia get on there and correct it so that us who rely [too heavily?] on it do not come away misinformed?

Why have artificial gravity at all? I would have thought that the benefits of freefall outweigh the drawbacks. The question then would be addressing the drawbacks. If muscle atrophy could be prevented through electro-stimulation during sleep or somesuch, what other drawbacks need to be addressed?

ghwellsjr: pedantic and adds nothing. I was emphasising frames of reference as this IS the starting point for understanding event separation across spacetime. The poster appeared convinced that spaceflight would lengthen his life and I wanted to disabuse him of the notion. The final paragraph...

Keep thinking. Remember this spacetime malarky very nearly sent Albert over the edge, and they never Nobel'd him coz they thought it wacky. It takes a new pair of eyes - and probably a young pair if history is any guide - to see it from a different angle. But do keep thinking, otherwise you...

Oraclelive : You must have this clear in your mind: The space traveller's ageing process does not slow down! Let me be as clear as I can. The space traveller experiences everything just as he would on earth. His seconds are seconds as he experienced them on earth. He beard grows as it did...

Thanks for the considered response. I suppose that I was looking for a response here beyond what I have received. I am content that I understand the current theory. I am not content that the theory satisfactorily explains the phenomena that we now experimentally see. Well we all know that...

I think that there are two kinds of scientists. Those who know it! - "I have been taught why this is so and I can prove it to you" And those who think about it! - "Why is that so?" and then go on to discover why it is so. Unfortunately the world has a surfeit of the former and a deficit of...

Thanks for taking the time to reply - I have learned something. For me the colour of three is usually a blue that I would describe as azure. Four is very definitely mauve and two a sadly dull green. I will not bore you with the rest - though some of the fractions are quite bizarre! And the...

Time in the space twin's frame of reference slows down wrt the earthbound twin's frame of reference. His clock slows down His heartbeat slows All known physical and biological functions within his reference frame slow down ...all with respect to his earhbound twin. In his spaceship...

I would also add: "What I don't understand is if no adjustments were made would person A run out of water first? Since B is dripping at a slower rate as observed by A than this would seem logical. If no adjustments were made what would happen if B were to land and water bottles were...
