quote:Originally posted by SandwalkerO's and A's , now GCSE's (all pre-university).O'level Exams - Secondary Education (High School).A'Level Exams - Sixth Form and College (Sixth Form - an extra year (or two) at high school, College - the bit between School and University or career (Vocational/Technical colleges).There are now also Sixth Form colleges, another tier of confussion, for schools that now don't have their own Sixth Forms, or pupils that don't want to study in the Sixth Form of their old school.University - I think we agree on that.Just to confuse the issue a lot of colleges are now called universities, but there are A list universities and B List, the A list being the old uni's ie Oxford, Cambridge, Essex, Anglia....Don't get me wrong some of the old colleges (now uni's) are very good and should be in the A List, but over here we are still snobs, an Oxbridge Degree (Oxford/Cambridge) is still considered best. The statements in the last two paragraphs are highly volatile and may explode in the hands of anybody who didn't gain a degree in an A list Uni PS: I didn't!PPS: Any views stated are mine, you may agree or disagree, its your choice!
quote:Originally posted by gsmollinRadeon, is that your insight about the parallel orbits inside/outside the event horizon? If so, then you are pretty insightful. It was just this problem that led Stephen Hawkings to propose the quantum radiation from balck holes. Of course, the Rooskies were working on it too, but H had the better math, and he was able to explain away the thermodynamics problems with black holes at the same time. GR is a classical theory, and does not answer all the nitty-gritty questions, but it has been tested to great accuracy where it does apply.
quote:Originally posted by UltimaIt's possible that there is a super massive black hole at the centre of our galaxy.... so that has a direct effect on us, as the whole galaxy is formed by it. Plus gravity has an infinite reaching effect, travelling at the speed of light (most likely) your gravitational force is effecting everything around you.
quote:Originally posted by LaithI tried to find a thread to put this in, i hope this is goodI'd like to know Why is time affected when we travel at the speed of light? how or why are they related?Laith
quote:Originally posted by LaithObviously I know how to start a new topic, you really didn't need to go in detail that much, ill try to look better through old threads next time, or start a new one.

quote:From these tenents, we have a number of surprising results.a. Distance is not conserved, it can contract.b. Time is not conserved, it can dilate (slow down).
quote:As to why it doesn't go backwards... according to Minkowski, that's the way it goes. The dimension is -ict. Time flows into the past at the speed of light.
quote:Of course this immediately begs the question as to why time can't be reversed, whatever reference direction we choose to start with. I suppose the answer is that would require faster-than-light travel.Now black holes are a different story.
quote:and doesn't the fact that if light cannot escape a black hole say there is a force that moves faster then light? Otherwise how could it capture it.
