Being able to fly was never against the law of physics.

Here is a list of the laws of science.

It actually is possible to break these laws but we have no control over that and that is a completely different topic.

It used to be the law, that no human could run a mile under 4 minutes. Then in 1954 some one finally did. Shortly after that, lots of people did.

I don't think we have even close to a full understanding of how the universe works. I think we have theories, that are either correct, or incorrect. Take the law of gravity for instance. It sure makes sense to me. I was taught it in school, and I just accept it as the truth, but what if it's wrong, what if it is basically right, but there is an exception to the rule.

As I said before, this perpetual motion machine is probably a hoax, but I don't think progress is made, by accepting what has been taught to us as absolute truth.

Can you give me a definition of a physical law? I think that might be our misunderstanding. I think we are talking about two different things.

You are right about that but the definition of theory is much different than most people take it as. For a law of physics to be a fact, lets take gravity for instance, it has to be proven to work in every instance possible. That means we would have to make sure gravity has worked in every instance and that is impossible so it impossible for some theories to become laws. But, out of millions of tests, there has not been one test that has even made a hint that the theory of gravity could still be wrong. We are 99.9999999% sure that gravity is right, there is a possibility that it is wrong, but that would most likely because of a unified theory and everything would be different when/if that happens.

Yes, but there are no alternate theories to gravity or evolution that has any scientific backing so we can only teach one theory.

Every known instance.

All I'm trying to say is this, 500 or so years ago the conventional wisdom was that the world was flat. We look back at that, and shake our heads, and say how could people be so ignorant. I think it's more than possible, it's probable, that 500 years from now school children will read what we believe now, and laugh their asses off.

Not sure if this would go here - please move if you know of a better place

ORNL, UT getting greener
Oak Ridge will be site of one of three bioenergy centers
By Andrew Eder (Contact)
Wednesday, June 27, 2007
BIOENERGY SCIENCE CENTER
• Location: Joint Institute for Biological Sciences on the Oak Ridge National Laboratory campus
• Purpose: Developing costeffective and sustainable ways to produce biofuels from plants
• Researchers: ORNL, University of Tennessee and a coalition of universities, research institutions and private companies
• Investment: $125 million over five years from the Department of Energy’s Office of Science
OAK RIDGE — Tennessee’s effort to position itself as a leader in renewable fuels kicked into high gear Tuesday with the announcement that Oak Ridge will be the site of one of three coveted national research centers.
Researchers from Oak Ridge National Laboratory will lead a team that includes the University of Tennessee in exploring ways to produce fuel from plants at the $125 million Bioenergy Science Center.
Martin Keller, director of ORNL’s biosciences division, will be the project director and principal investigator at the center, which the Department of Energy will fund for five years.
The new research center will be located at the unfinished Joint Institute for Biological Sciences, a state-funded, UT-owned facility on ORNL grounds.
The ORNL bid was one of three successful proposals from a pool of more than 20 applicants in a process described as intensely competitive.
The federal research effort will complement $72 million in recently approved state money for biofuels research, including more than $40 million for a demonstration-scale ethanol refinery.
“Certainly, seeking ways to reduce our consumption of fossil fuels is the right issue at the right time at all levels of government,” Gov. Phil Bredesen said at a press conference at the lab.
The new research center will focus on the challenges of cellulosic ethanol, a gasoline substitute made from plant materials known as biomass. Researchers will focus specifically on switchgrass and poplar trees. Most domestic ethanol is made from corn.
“Starch is put together in a way that’s somewhat easy to break apart, so you can make things out of it,” said Brian Davison, a chief scientist in ORNL’s biosciences division, who led the proposal process. “Cellulose, which is the structure in wood and paper and grass, is put together in a way that’s virtually impossible to break apart.”
Davison said researchers would use a “suite of approaches” to analyze and modify the makeup of plants and improve their understanding of the microbes and enzymes that break down plant materials, allowing them to be converted to ethanol.
At the same time, the state will offer incentives for farmers to grow switchgrass, and the 5 million-gallon-a-year pilot ethanol plant will let researchers and companies test new technologies.
UT, the lead institution for the state-funded ethanol refinery, is close to finding a partner to build the plant and will locate a site after that decision is made, said Tom Klindt, interim dean of the UT Agricultural Experiment Station.
“That connectivity from the fundamental science to the crop science and the refinery processes, that whole package is probably one of the aspects that led to this being a winning proposal,” said Thom Mason, the incoming ORNL director.
In addition to ORNL and UT, other members of the research team include the National Renewable Energy Laboratory, Georgia Tech, the University of Georgia, Dartmouth College, the Samuel Roberts Noble Foundation, individual researchers from several institutions, and three private companies — ArborGen, Verenium Corp. and Mascoma Corp., all of which were chosen for their expertise in specific technical skills, Davison said.
The other national research centers will be located in Madison, Wis., and near Berkeley, Calif.
A federal renewable fuels standard calls for 7.5 billion gallons of the nation’s fuel supply to come from renewable sources by 2012, and a bill that recently passed the U.S. Senate calls for 36 billion gallons by 2022.
Many scientists, economists and others worry about the effects of relying on food crops to produce renewable fuels. Cellulosic ethanol offers the opportunity to produce dedicated energy crops on surplus farmland, and boosters think the plant-based fuel could spur development in rural Tennessee and beyond — if researchers can make the process economical for wide-scale commercial production.
“We know what the trends are, and the trends are that we have to drive the cost of the renewables down,” Mason said. “And the trends probably also are that the cost of the fossils are going to be up, so you don’t have to be a genius to figure that those two lines are going to cross.”

It was only a law among those who automatically knew because they 'felt'. There was no such laws based in logical reasoning.

The 'law' was found where speculation was sufficient to 'know a fact'.
