Hawking, new theory on information paradox right or wrong? Does anyone have any views on Stephen Hawking amendment to his 30 year old theory of black holes and the *information paradox that was recently challenged? Once past the event horizon information is lost forever and only the energy...

I think that the main problem is that the majority of the public don't understand the subject. Environmentalists seem happy for the public to draw the conclusion that mankind produces all of the Co2 and this is simply not the case and by a long way. Additionally, the majority greenhouse gas...

Another point is the fact that an anti matter/matter interaction will only annihilate the combined mass as energy. In the programme scenario only a small amount of anti matter was produced, so although this would have catastrophic consequences for the immediate locality, once the interaction...

Yes, but what if it were our Universe that was the one that had the garbage/criminals dumped in it!

[FONT=Comic Sans MS]Entropy increases over time, which ultimately means total disorder and death or inactivity. However, this only applies to a fully closed system, of which it is presumed the Universe is the ultimate example. Q) If the Universe is infinite in all dimensions including time, can...

Stephen Hawking has stuck to his guns regarding the ultimate loss of information from black holes in our Universe. However, his new theory uses the many worlds/sum over histories hypothosis and states that there are sufficient (ie:- a majority of) alternative Universes, where the prevailing...

Heat death simply means that entropy or total chaos/disorder has reached its ultimate conclusion and every part of the entire Universe/Cosmos has the same temperature as every other part. Without a difference in temperature, no work can be extracted nor energy generated from any system. Even if...

The uncertainty principle states that you can never know with any accuracy the precise position and velocity of a particle, because the measurement of such will alter them in an unknown way. Therefore, if you do not know either the position or speed of a particle, how can you a) aim another...

Not at all Methinks you got the wrong end of the stick. Whilst I agree that the particle density in space (which is mostly vacuum) is very low, it isn't zero. Over a period of 15 billion years, even in vacuum, individual photons will encounter and interact with many particles during the...

Thanks for the info. Please excuse me if the question seemed simple, I'm not a physicist nor am I a mathematician, nevertheless I'm fascinated by the concepts of cosmology, physics and relativity. Unfortunately they aren't subjects which people usually have much interest in, so they don't crop...

Light speed niavety?? Light speed naivety?? -------------------------------------------------------------------------------- The speed of light - c is a fundamental constant, at least in vacuum. However, it appears that c varies and slows down at the interface between different density...

It's how you look at it Seems to me that you have answered your own question (see italics). As the early universe expanded and cooled quarks and other exotic particles began to form and then matter & antimatter. This from a perfect, in your terms, soup of energy. As these processes...

Would it be true to say that energy is the emission, or potential emission, of radiation caused by the interaction between particles? If so then this would be true of matter/matter, antimatter/antimatter or matter/antimatter interactions.

Relative viewpoint Alkatran: Oh I get what he means. He's saying that when you switch a lightbulb on, the light sphere created stays in the same spot, but we are shrinking in such a way that makes it look like the light is expanding at c. Doesn't it depend on your viewpoint relative to the...

At last a voice of reason! If only more people would take the time to examine the data presented by environmental alarmists objectively and ask questions! I have found that when you examine the data they present (when they can be bothered!) closely, you find all sorts of discrepancies...
