but what about gravitational energy??, this must be the most fundamental and crucial force in our universe as it gave rise to our current universe, gave rise to all galaxies, gave rise to all planets and will eventually destroy ALL again.
Once all that is, is once again in that singularity and all laws break down these forces will cease to be and (providing you believe in a cyclitic universe) it will all start again.
However gravity will always be there (potentially) as it is the mere effect one mass has upon another, even the singularity will have a gravitational effect on another body.
I think i have lost track of what i am asking, i do that a lot!!! i guess that i am saying that if you introduce a mass/ increase the mass of an existing body you will CREATE more gravitational energy, and the question is; does that contradict the 'you cannot create or destroy energy' law (if it is a law).

Im working on a lab and I am stumped on how to find specific heat. I have water and 100g Iron Fe at a Intial tempature of 20c and I place the iron fe in a test tube and heat it inside of a beaker with 150ml of H20 which is at 20c as well. I heat it untill the iron fe and water has reached both 100c and place the Iron Fe into a Calorimeter filled with 100ml of H20 at 20c as well. Once I place the 100g of Iron Fe at 100c into the Calorimeter the tempature of the water goes up to 28c. How am I supposed to find the specific heat of Fe using that senario can anybody please help!!! Thank you in advance

a) Ag +(aq) + 2NH3(aq) = Ag(NH3)2 +(aq)

b) 2HCl(aq) + Ca(OH)2(aq) --> CaCl2(aq) + 2H2O(l)

c) Al(OH)3(s) + OH-(aq) --> Al(OH)4-(aq)

d) BF3(g) + (CH3CH2)2O(l) --> (CH3CH2)2OBF3(l)

Australia Ends Ban on Human Cloning

CANBERRA, Australia (Dec. 6) - Australia legalized the cloning of human embryos for stem cell research with a vote by the House of Representatives Wednesday that lifted a four-year-old ban on the procedure.

The parliament passed Australia's first laws on stem cell research in 2002, allowing scientists to extract stem cells from spare embryos intended for in-vitro fertilization but preventing cell cloning.

The law passed Wednesday allows therapeutic cloning, the splicing of skin cells with eggs to produce stem cells, also known as master cells, which are capable of forming all the tissues of the human body.

Scientists hope stem cell research will eventually lead to treatments for conditions including Parkinson's and Alzheimer's, as well as spinal cord injuries, diabetes and arthritis.

Opponents said the bill promoted unproven science that did not respect the human rights of the unborn.

Is this a good idea? Should the U.S. do the same
