Ahhh, cheers Dale or as my daughters used to say, and in this case they'd be dead right "that's so random!"
I'd say horribly random. c'mon - how do you people ever finish a physics course with having common sense assaulted like this at every turn. :)
But thank you - ..
okay russ (accepting the details of the elements age distribution and thank you,) - each individual atom's time path/age does affect the individuals liklyhood of decay ...doesn't it? ...by the following
If you put half a piece of some element with a particular decay half life in a spaceship and...
Hey thanks Russ, might just need to get to grips with the first part of what you say ...
Is that true? How can something with a beginning (big bang) and a process (particle - planet - galaxy formation) in a finite time not have a normal distribution? Wouldn't the paths and histories of any of...
Hi, thanks to a different thread/question on this forum I've come to appreciate time dilation ..somewhat. And from that I wondered if, given the range of locally measured times aboard any and all particles in the universe, given their different trajectories and histories since the big bang...
Thank you all for your guidance. I have come across a sufficiently simple, and hopefully too, a fair representation of time dilation on the web.
This scenario I think is akin to an observer watching the operation of a moving bouncing photon (mirror) clock. In the vid the 'moving' reference...
rkyeun, Ibix and mfb thank you for your responses, this matter does seem to engender endless sense of 'but what if's ...' which seem impossible to resolve in the absence of a very thorough and complete understanding.
haha and now in that vein a question please ...and then a comment of sorts.
My...
Thanks again PeterDonis, I guess this threads title is asking whether my trip is in effect faster than light - which it is not (from Earth's or my destination's perspective) but the corollary is that to those on the trip - it is FTL - given their distance measurements taken before they start...
Thank you MisterT and PeterDonis, seems my imagined rocket trip was sunk by an annoyingly odd universe however, and if I'm reading things right, and using the well established scientific principle of confirmation bias as my guide, it seems that the idea of the relativistic rocket linked by...
Hi, Please not too many sighs but I'm stuck with this my miracle realisation - the scenario is -
I'm in a rocket (tons of fuel ) - I blast away (from Earth say) - accelerate hard for ages and by my special onboard inertial calculator I have got to 100 000km/s (with respect to earth). Switch the...
Charles he is saying a bat may travel faster than sound - but the ...constriction of the maths on the measurement of that speed will never produce a result greater than the speed of sound. So he is saying - bat A hears bat B traveling away at say 0.7 of the speed of sound - and B hears C going...
Thanks Dale - "The key point of the derivation is that c is invariant" ..gee I thought he had attended that but I could be wrong and too with respect to what Charles has said I'm having a re-watch. And thanks Charles.
Thanks mfb - if the case has it that 2 galaxies of say diameter D approach each other - one on the horizontal, the other say 45 degrees to it, their centre of masses both lying on the same horizontal plane and their peripheries are say less than 10D apart which I imagine provides for a clear...
Sorry that doesn't help much - what is 'utter nonsense'? the use of an imagined world limited by the speed of sound, his derivation of special relativity or the inference I seem to be able to make about it?
