Sep 5, 2011 - have people now worked out why pulsars emmit radiation yet? i thought they had?

Mar 11, 2012 - If you took a teaspoon (or small amount) of a neutron star and it weighed >> (much greater) than the earth, then if you put it on earth, would the center of mass of the earth fall towards the small itty bit of neutron star? Or would the earth star flying around the little piece of neutron star? I guess the real question is: Is the force of attraction due to the piece of neutron star enough to break through the strength of attraction that holds matter together? I love science. The Q's NEVER END

huntgiri Says:

Mar 21, 2012 - He lived physics his entire life. I hope he turned into a Neutron star after leaving this Earth :)

nvshd Says:

Mar 30, 2012 - One teaspoon doesn't weigh more than the Earth (it weighs about as much as a mountain). It just is so dense and heavy that it would fall through the floor. And then the ground. And the mantle and finally plunge into the core.

CuriousGeorjay Says:

Mar 30, 2012 - I was saying IF you could take something weighing more than the earth. The fact that I said Neutron Star is irrelevant. The object's name is arbitrary, I am talking about a situation in which some small volume of something weighs much more than the earth, and what would happen if you put it on the earth. But you thought my question was about a Neutron Star.. no... it was much deeper. So thanks for the answer, but it doesnt answer my question.

CuriousGeorjay Says:

Mar 30, 2012 - human bodies don't spontaneously gain 10^60 times their mass. In fact I bet Feynman is decaying as we speak.

nvshd Says:

Mar 30, 2012 - Then yes, the Earth would accrete onto/into that object. The only objects that dense and small that exist or could exist under the laws of physics are neutron stars and black holes. If you put it a little further away, you could get the Earth to orbit it, along with the Moon. And, depending on its mass, the rest of the Solar System, including the Sun.Similarly, there are black holes and neutron stars that orbit very close to other stars, and they accrete or "steal" matter from those stars.

huntgiri Says:

Apr 11, 2012 - Sometimes it's not always about physics...is it?? :)

CuriousGeorjay Says:

Apr 11, 2012 - actually, in this case it is. what you proposed is not possible according to our current understanding! If you wanna think big (which is good), you're gonna have to at least hang on to the laws that we currently understand through experimentation, or else it's just a spew of nonsense.

krickrack Says:

Apr 25, 2012 - I think you're too serious... it was obvious that huntgiri didn't really think that Feynman could turned into a Neutron star... you are boring..

i7887 Says:

Apr 26, 2012 - If me could see precision cosmology these days he would be so excited.

CuriousGeorjay Says:

Apr 26, 2012 - No, i just feel like creative thinking should be used to power science rather than spiritualism. If you have ever wondered about science while reading your textbook and have seen how much beauty lies in what we have discovered, and what it all actually MEANS, you would not call me serious. People who study too much, or think about math and science too much are too serious, boring, or obsessive? Of course not! We are in fact just having a shitload of fun in a different way than you prefer.

krickrack Says:

Apr 26, 2012 - wow... seriously, everything is not science...if you don't understand or accept that... you have a problem..and what huntgiri said has nothing to do with spiritualism, it was a joke! do you remember what a joke is?And right now you're talking to someone that love science but can understand when someone is joking around...you're mixing things...

NCla94 Says:

May 10, 2012 - Everyone once in a while I think about the implications of gravity, and it absolutely blows my mind every time. I'm so excited to be taking physics next year in high school.
