Spontaneous Definition and 158 Threads

Can anybody direct me to a discussion on the effects of a sudden reduction of the Earth's gravity - say by 50%? Purely speculative, of course. I'm assuming its orbit around the sun would be essentially unchanged, but that the moon would recede or maybe head off on its own merry way. Any other...

Which of these is spontaneous?? Which of the following are spontaneous at constant T and P ? (a) DH = -10 KJ DS = +5 J/K T = 298K (b) DH = +5 KJ DS = -5 J/K T = 10K (c) DH = -10 KJ DS = -40 J/K T = 300K (d) DH = -10 KJ DS = -40 J/K T =...

http://arxiv.org/pdf/gr-qc/0501014 A static 10 dimensional universe can arise spontaneously, by a quantum fluctuation?

Hey this is a weird subject but have any of you ever thought about what causes it, if it is indeed real? I have a theory but it may be totally wrong as I don't have a background in physics or chemistry. Well I read about solar neutrinos and how they pass through our bodies all the time. They...

'splaing to do... I don't know if I am coming or going. But, I am not leaving the forum. I just said, "Good-bye" earlier. <shrug> I am enjoying this forum, the posts, the reads and topics. (Greg? You can keep the $25.00 fee) I have to tell you (those reading this) that I am a very...

The following theory is something I have been working on. It combines ideas of quantum mechanics to explain the possible source of all phenomena, I really want to see some feedback. In quantum mechanics we all know that there is always some probability that a particle entering a potential...

I'm searched for this on the forum and came up with no real results... I'm looking for open opinions or experience either in support or against the matter of Spontaneous Combustion! I believe it is possible, but as just another rarity within our materialistic world. Could it be that we have...

I have a question I hope someone can help me with. Does light ever spontaneously lose energy? What I mean is, would, say, an infrared wave be traveling along and suddenly shift to microwave radiation, and maybe later to a radio wave, without any outside influences having affected it? If...
