What does the standard model tell us about spacetime?
Q. I know it is successful at telling us about particle interactions, but what does it tell us about spacetime itself? Thanks for enlarging your answer, epidavros. I was just going to ask you to enlarge it a little. I suppose what I really want to know is what it tells us about spacetime that wasn't in General Relativity, because I'm fairly ok with that. All great answers so far. It's going to be hard choosing, so I may put it to the vote.

A. Unfortunately, very little. Spacetime is just unchanging background framework for the SM. The SM is Lorentz invariant. That means it agrees with special relativity's static model of spacetime. General Relativity is the only dynamical theory of spacetime at present, and SM is a quantum mechanical theory. QM and GR in their present forms have irreconcilable differences.

What does the formation of heavy elements tell us about the age of the solar system?
Q. What does the fact that heavier elements are formed from supernovas tell us about the age of our solar system? Part of my physics project - I need a few pointers as I'm a bit stuck! All I can think of is that it tells us our solar system is ancient because supernovas happen after billions of years of a sun being 'stable'. Is that on the right track? So if these elements are only produced from supernovas, then does that make them virtually non-renewable?
Asked by ~ Mystic Dreams ~ - Mon Feb 9 14:50:12 2009 - - 2 Answers - 0 Comments

A. In the early days of the universe, all that existed was hydrogen, helium and traces of lithium. That's all. All other element were formed in the core of stars and was liberated when those stars went supernova. The heavier elements enriched the cosmic gas, which can then form solar systems and planets with a higher proportion of those. Therefore, given that our system has a fair amount of heavier elements (oxygen, nitrogen, silicon, iron, etc.) then it has to have formed from gas that had been around quite a bit (actually, estimations are that our sun is a 3rd generation star), therefore cannot be as old as the universe, since it had to wait for those 1st and 2nd generation stars to go supernova to provide the raw material. So, it is a (rela [cont.]

Q. My friend lives in Africa and I want to her to study in the US with me( I am a US citizen) as a international student. How do I go about making that happen? Or what steps would I need to take?
Asked by Queen X - Tue Aug 19 18:01:42 2008 - - 2 Answers - 0 Comments

A. first of all your friend needs to figure out what course or degree she needs to go in for and which area/state she wants to be in, then do online search for the universities accordingly. All the universities clearly specify their requirements for international students on their websites. This includes all the documentation and other things. Be sure to start with the process as early as you can as this can take a long time. Universities usually recommend the students to start with the process 6 months- 1 year before the intended semester of study. I hope I helped.

A. I don't know what state you live in, but almost all state have a Fair Housing Board that is governed by the state. You canusuallyy find them in thegovernmentt pages in the front of your phone book. Thirty day notice is the norm. Check out Legal Aid in your county or state also and a lot of states have a listing for renters rights too. If you call one and don't get the answer your looking for ask them who would know or who can help you. Google rental laws for where you live. Good luck. A lot of landlord will takeadvantagee if they can or maybe they don't know whats legal. There are usally firm laws reguarding damage. They cannot make you pay for normal wear and tear and they have to prove the other damages.

A. Actually, torskie is somewhat correct. you will need an unlocked quadband gsm phone. Quadband allows you to use it anywhere in the world. But wrong about that you only need the phone. You do need a prepaid SIM card. And it's only possible to buy a SIM card for multiple countries IF that service is availble in that country. I'm posting a link at the bottom that lists a SIM card that will work in multiple countries; I hope this helps you.

A. I assume you are a US citizen. If you did not owe any tax then failure to file is not an offense and there is no penalty. If your non-liability for tax depends on claiming the foreign earned income exclusion, then you need to file back tax returns for six years (although the IRS is not excluded from demanding earlier returns or claiming tax for earlier years, it generally does not do so, nor does it usually want nonfilers to bother with earlier tax returns). In general the IRS is glad to cooperate in nonfilers regularizing their status. If you work in China for a US organization or a subsidiary of one, then your spouse may be eligible for "expedited naturalization" irrespective of never having lived in the USA.

This is the exact response the companies want from us, because that will make us buy their product. We should all just be grateful that we are fed and clothed, with warm houses and people to love that are still alive. Not everyone gets that.

A. In the US, we are seeing more and more of our morals and values be slung out the door so that liberal views can move into place. Our children are being told that abortion is better than abstinence in most cases. Abortion should not be a political issue-- it should be illegal as a law and nothing more. It isn't a 'right' to have... it's just like saying 'doing drugs should be legalized as a right to anyone who wants to do them' or 'it should be a right to murder my friend because he's a nuisance to me'. The US has gone overboard with freedom and rights. Abortion is murder and that's all there is to it.
