I was pondering the information paradox presented by Hawking and the recent attempt by him to resolve it. I don't completely understand his answer, but it does seem to imply that the information might be in some kind of superposition, especially since it can't be measured by the universe...

Good response. I did a quick study on Goedel and think I have a better grasp on the incompleteness of math. Whether or not you agree with his LQG conclusions, please consider this statement: "Suppose the universe correlates with some patch of math. That patch cannot be complete and will...

Hello. It's been a long time since posting. I'm a layman who is intrigued but very confused about something I read recently. This article in Discover Magazine says: "We now know that mathematical truths cannot fall into predictable patterns and that perfect mathematical systems (ones that...

Dark Dimension This might go better in String theory, but couldn't dark matter be a fundamental 'particle' that exists in other dimensions? If all particles are vibrations of a fundamental string, then there's nothing that says there can't be particles that vibrate higher than light. But as...

DM as higher vibrations? Good discussion here. I used to deride Dark matter as a makeshift idea to plug the emerging holes in GR, or Newtonian at least. I guess what turned me around is string theory. For once Ican see how DM could exist. I don't think dark matter is one long brane...

I need more evidence to the contrary Are your measurements based on facts or a guess? Don't you think a massive body like the sun (and thus objects around it) would be effected substantionally more by such a pressure system than two paltry plates? :confused: I'll admit I'm guessing at the...

I'm curious why nobody has commented here. Is it because the idea is so idiotic that it is not worth addressing, or am I confusing you? Well, regardless I'm updating myself here, as later research has seemed to indicate dark matter isn't uniform throughout but clumps around galaxies...

I'm reading Hawking's take on ground state energies never being zero, and he adds an interesting point. He said based on the casimir effect the denisty of ground state fluctuations (wavelengths) are less by a finite amount between the plates, causeing them to draw together. To me this explains...

Still unanswered questions I do, and is the problem I'm having. I still need an explanation as to how we can measure the potential energy of gravity as a force when it is only recognized by its kinetic energy. Does this imply infinite potential energy, an amount of potential energy equal...

Gravity's potential energy Does this mean if we find a way to create regions of higher gravity, or even antigravity, it must violate the first law? Or is it possible (in theory) that the static pressure of gravity could be 'mined' for local use, therefore conserving total gravitational...

Gravity, vacuum energy, and the 1st law of thermodynamics. Great answers guys, thanks for the clarification. In retrospect, the slight slowing of Jupiter was so obvious as to have slapped me in the face. :redface: But I still have a little problem with the concept of gravity as a...

Greetings all, I am a newbie here. I'm also a layman, as you probably guessed by my question. And I obviously am missing something about the 1st law and how it deals with Gravity. It hit me when I was thinking about Jupiter's moon, Io, and how it is volcanically active simply because of...
