do u guys rekon there should be more maths in physics ! like in the real world. We should go more in depth rather than skimming over stuff. Then again if we changed the sylabus - most teachers wouldn't be able to teach it~!

- i no longer agree with the title ! :) Black hole DEF It follows from Newton's law of gravity that a sufficiently dense object's escape velocity will equal or even exceed the speed of light - tats what i was talking about - but this definition is not entirely correct!

well i have been saying for a while now : rockets cannot escape black holes

Well rockets cannot escape black holes – this however cannot be explained by Newton’s concept of escape velocity. You have to understand that Newton’s escape velocity is only for projectiles. – For example taking earth – say escape velocity is 27000 km/h – u do not need to accelerate a rocket to...

I would like to thank you for your reply, you did not do what politicians do all the time! - you replied with physics in a physics Debate.. I totally agree the escape velocity augment is totally inadequate - Alberts version is better - I will look into this.. thanks I actually posted this...

wow thats a great explanation! - i think i just stumbled on a conundrum !! well it is explained now in Phys - wiki - ill probably get more info on this tis very interesting - thanks all for the debate Popular accounts commonly try to explain the black hole phenomenon by using the concept of...

what i wasn't talking about light.. rockets escaping black holes

And so can rockets - by the way it is hawking radiation that cause small black holes to be destroyed!

You can't escape a black hole because you cant go faster than the speed of light this is true, however most people don't know why, which is more important than the truth it self. Knowing the answer by itself will only lead to miscoceptions and relgification of science, my motto in science is...

Ok I am sick of hearing, stuff can never escape a black hole -.. so the "escape velocity" is greater than the speed of light - but the escape velocity only applies to projectiles! - ie the initial min velocity to escape a gravitational field where the velocity is zero at infinity(unachievable...

Hey any one know what must be done when a teacher loses your half yearly tests - it happened to me acctucally to more than half of our Grade - which is not that much only 12 people....
