UK governments have centralised power more and more since Thatcher started the trend of trying to do everything herself. So, whoever you get in, they can't get anything done, because they people in the top layer get bogged down in too much detail but they won't devolve decisions to local...
Can't edit my posts. Is this some new requirement to type perfectly every time? Is perfection being demanded by the ethereal rulers of religious site-ery?
Actually some particles can travel faster than light for set periods , as I understand it. But anyway, I’ll have a look when I get time. You seem a bit stuck on it though, stepping back and considering the bigger picture (the factors that make it hard to picture what is actually occurring on a...
To invert the idea, in a massless universe, where nothing has any mass, everything would be instant. Movement, communication, whatever else, regardless of any notion of distance would be instantaneous, as there would be no need for a speed limit. Once you have mass, though, a limit is...
It takes 2 more years from the perspective of an observer. The observer experiences the time difference between one event and another, because the observer is not travelling at the speed of light.
A thing with no mass will travel at the maximum speed the universe allows, which is the speed of light. For something moving at the speed of light, time has to be zero, as otherwise that thing could move faster. Things with mass can move, using energy, and they move within frameworks of location...
Maybe it's the movement part that's missing. In terms of the diagram, iow if we take the photon to be like a brick or something (with mass) in motion, the zero time is in effect the result to the time axis bending towards the speed axis. Time slows (for a photon it isn't there at all) for the...
Other than a tiny fraction of time at the beginning (before it interacts with anything) and end of its existence, there is no time for a photon. In relation to a photon, time is not a relevant consideration. It only becomes relevant if an observer comes into play. So, you don't get to anything...
