Hmm, alright...It seems to deny energy/mass balances though if a large star were to suddenly become a point of singularity and have more mass than before. Where the heck does this other mass come from? O_o
Hey, I am a little confused with the nature of black holes.
I am under the impression that time is infinitely slow at a black hole's existence.
I am also under the impression that black holes are a point of singularity, but have a defined mass.
Gravitational force is only caused by mass...
The question I want to ask is pretty much in the title: Why is string theory becoming less of an excitement amongst the scientific community?
I don't want to sound picky, but my background in physics is pretty inferior. I understand that the explanation is mainly in the mathematics, so, just...
Hey guys, thank you for the answers that some of you provided. Sorry for not reading the FAQ's and checking previous forums. I'll do so for my next threads I want to start.
I've actually never heard of a phonon, but that's pretty cool =D. So I suppose since phonons have quantum properties...
I am extremely confused when it comes to particle-wave duality outside of the electromagnetic spectrum and quantum world. Are sound waves strictly waves or do they have "particle"-like aspects?
I understand that every particle has its own wave. Does this apply to every wave having a...
Archosaur,
Yes I was familiar with the precession of the Earth but I never really connected it with being a gyroscope haha. Why does the Earth not pull in all directions equally? Is it because other massive bodies further away, such as the sun, pull back?
Well these are very interesting. They are also very similar haha. This thread is kind of analogous to asking "what do you think of the health care reform?" on a democratic or republican forums page haha. Maybe I'll take this question to a philosophy forum.
Alright, I certainly agree that both arguments are worth exploration. Light is not readmitted in every direction I believed, though. Once it hits the water molecule it is either reflected or absorbed, right? The absorbed energy is transformed into another type of energy, such as heat or used...
This is really interesting, cesium. I enjoyed reading this. I believe I understand most of what you are saying, but could you clarify absorption saturation and "extinction"?
I do not know all that much about the chemistry and physics behind the contributions carbon dioxide makes to the...
Now that was VERY helpful. Thanks a lot drasil. Could I draw a parallel between infrared and carbon dioxide, and Water and Microwaves? I understand microwaves use the polar properties of water to turn them, which results in more kinetic energy and more heat. Infrared causes carbon dioxide to...
Haha I've been begging for someone to answer this. You actually answered two questions for me...
1) That we can only see 13.7 Gly because light has only been traveling for 13.7 Gy.
2) Since the Universe is approximately 78 Gly in radius (assuming it's a sphere), that means that it expands at...
Alright, thanks for clarifying that; that was very helpful.
Hmm...assuming the theory that the universe started as a point of singularity is correct...I wonder if it rotated due to some internal inertia, and if so I wonder if inflation only occurred because of that rotation and inertia. haha...
