I designed a memory controller before. Let me try to explain. Processors or micro controllers run at a much higher clock rate than its peripherals. Accessing instructions or data outside the processor reduces the overall performance because the processor has to stop and wait for its peripherals...

It's awesome! Thanks! :D

It is not book, but I watched it and maybe it recommendable. It's entire course videos, homework and reference books for the entry level of astrophysics at Yale university. Open Yale Course ASTR 160: Frontiers and Controversies in Astrophysics...

If you would like to, you take take a look at the video here http://youtu.be/A2IOOnAdP2s directly from 32'38". It won't take you too much time. The whole argument starts from "the cause", and I think it probably went wrong in the end. And the main problem to me is that he says time stops. But...

Haha :D I didn't watch "Through The Wormhole", but to be honest I am a big fan of Dr. Kaku. So, it is probably a bit too late. I found some ebooks of "The First 3 Minutes" on the Internet but they are incomplete,... To really think about these, a lot of time should be perhaps spent on math, to...

Yeah, thanks! OK. I will take a look at the book you suggest. From your words, you perhaps didn't watch the documentary? If you would like to, you can watch it on YouTube here before it is deleted. http://youtu.be/A2IOOnAdP2s In the documentary, the arguments aren't supported by equations...

Yes! That's what I think too. But in the documentary, at 38' 59", he says ... "here too, time must come to a stop. You can't get to a time before the big bang because there was no before the big bang, ... there is no cause because there is no time for a cause to exist. For me it means there is...

Hey, first thanks for replying! And, yeah, you are right. But my question remains. What does Dr. Hawking mean when he says there is NO TIME? According to the theory of relativity, the observer outside of a black hole perceives a slower ticking clock which falls into the black hole. However, for...

After watching Discovery's documentary "Curiosity: Did God Create the Universe?", I can't stop but wondering,... Dr. Hawking claims that there is no time in a black hole. Time stops due to the Gravitational time dilation. The very beginning of the universe is also a black hole. There is no time...
