Question about the "edge of the universe" Okay, the farthter away you look, the farther back in time you are seeing, right? When you talk about seeing some object 11 billion light years away, you are seeing something as it existed a long time ago. So, since the universe is expanding, that...

And what will we find there? Maybe us. What would be wrong with considering that we ARE on the edge of the universe! After all every where we look we can only see into the past where thinks get smaller and older the further away they are until reaches the very small BIG BANG space. The...

A uniform chain of length 8.00m initially lies stretched out on a horizontal table. a) If the coefficient of static friction between the chain and the table is 0.600, show that the chain will begin to slide off the table if at least 3.00m of it hangs over the edge of the table. b)...

"Review of Cosmic Vision 2015-2025" begins: "The Cosmic Vision workshop at UNESCO on 15-16 September 2004 showed that Europe is richer than ever in ideas for what should be done in space science in the coming years. This workshop brought us a major step forward in developing the vision of the...

How would you describe the limits of physics?

Does anyone know what would be in a field that would have a light on it, except its a structure and not a house, it had 3 lights on it in odd places.I couldn't tell what it was.I don't know much about farming or anything like that but the fields on the edge of my town are growing crops and...

I know that there is a way to bisect an angle using that equipment, but is there a way to trisect it. I have heard it is possible to do it by constructing a regular polygon with sides of a multiple of 3 around the angle. Does any1 have anything?

What happens to light when it reaches the edge of the universe? it couldn't keep on traveling into nothingingness could it? becuase that nothingness would be space. it couldn't reflect off something unless there was matter at the edge to reflect off. the light must do something, it...

Would you want to see cutting edge theoretical debates? Howdy everyone, I am doing a little bit of 'research' for a website idea of mine and I am very very eager for some feedback on it. Essentially I want to know if you, the people of our world who are interested in...

First, we find in the skeptics dictionary that the concept is not well defined. http://skepdic.com/occam.html Next, the concept predates modern physics and is no more valid than 12th century physics. Consider Occam's original premise: Clearly the credibility of this premise died with...
