Galileo's theory....?

No, because Galileo was working with the tenet of gravity, not that of air resistance and buoyancy.  In a vacuum, the helium balloon would fall just as fast as a piece of led.

Don't know yet, but lots of wild theories and mathematical approaches being tried (some, via\nhttp://myweb2.search.yahoo.com/search?p=4%208%2015%2016%2023%2042):\n\nhttp://www.d.kth.se/~dicander/lost.html\n\nhttp://www.4815162342.com/forum/viewforum.php?f=3

Galileo's principle of relativity essentially states that, regardless of an observer's position or velocity in the universe, all physical laws will appear constant. From this principle, it follows that an observer cannot determine either his absolute velocity or direction of travel in space.\n\nhttp://farside.ph.utexas.edu/teaching/jk1/lectures/node7.html\n\nhttp://en.wikipedia.org/wiki/Principle_of_relativity

IT WOLD BE GREAT IF WE COULD GET EINSTEIN BACK TO WORK ON IT.EINSTEIN SAID IT WOULD WORK,AND WE HAVE NO OTHER BRAIN CLOSE TO HIS.I BELIEVE IF HE WOULD HAVE LIVED LONGER HE COULD HAVE SOLVED IT.THEN AGAIN IT MAY TAKE ANOTHER COUPLE HUNDRED YEARS,LIKE IT DID BETWEEN NEWTON AND EINSTEIN.MINDS LIKE THEIRS ONLY SHOW UP RARELY.

I don't know of one. Observations could be explained by having the Earth fixed and the Sun orbiting it. It's just that our laws of physics would have to change.

Hey babygurlgonnaloveonu you have asked what is totally QUESTION NUMBER ONE in physics. It's an exciting question which many teachers secretly don't understand and so their students get this hazy idea and kind of go thru the motions. \n\nWow, it is so basic, that it took a super-genius, I mean way smarter than Einstein, to figure it out. A good old farm boy, astrologer, magician & alchemist, religious fanatic, mathematician and all around kook. Yep. Sir Isaac Newton. You gotta wonder what kind of parents would name their kid "Sir"\n\nWell we all know what a force is, it is a sort of push or pull -- think of it as something that changes or *tries to change* the motion of stuff.\n\nNewton first figured out that if you leave a thing alone, or if the pushes and pulls on it cancel out, then it will sit there like a lump. Like those drivers wearing hats, and like sit there after the light has already turned green two minutes ago. \n\nOr else a thing  will keep moving in the same straight line direction and speed  like those drivers wearing hats who go 40 mph on the expressway with their turn signal blinking on and on. This is known as "THE HAT LAW".\n\nAll was well until he noticed that things move faster in an amount equal to how much you bully them or push them around. Twice the force, twice the fasterness and fasterness (also known as acceleration). This is called the "YOU BIG BULLY LAW".\n\nThen he discovered a fly in the ointment. His HAT and BULLY laws didn't really explain all that much. Something was gumming up this beautiful theory. We call it MASS and it is still an unknown mystery as to what it really is. So we vaguely call it the amount of stuff or matter in a thing. \n\nSo he found out that for a certain force the faster-isity (acceleration) is cut in half if you double the mass. The bully has to push twice as hard to fasterize two little kids. So he was like "I'll just add that in, and all will be cool". The "YOU BIG BULLY LAW" and "THE HAT LAW" totally did it all. Wa ta da babee!\n\nBut then Newton had a road accident. He was gunning his Harley over London bridge at like 250 when a bug  hit him in the mouth and knocked out one of his wooden teeth. He was all "Why am I so in pain?". And the bug as it squooshed said "Help! I'm a bug!"\n\nSo spitting out the splinters of his wooden tooth and the splattered bug, he had this revelation. He realized that because he was moving so fast, and the  bug slowed down so fast, that even a eentsy mass like a bug was like taking a hammer to his tooth. \n\nHe noticed that the force was equal to the mass of the bug times the speed of impact all happening in a brief moment. Since Newton spoke Latin (he  was the love child of Joe Newton and an Italian governess) he wrote "Fastus buggus ina momentum hurtus like crazy." Today we call this "momentum". It is just "mass times speed" or "force times a small moment of time". \n\nAnd he realized that the bug smashed up his tooth, but also that the bug was squashed (like a bug) because they were trading the EXACT same amount of momentum. The force on the tooth by the bug in the moment of time was PRECISELY equal to the  smacko-ing the tooth used to stop the bug dead. \n\nHe said "Hey, like he broke my tooth, but I killed him soooo dead!" He did the math and found that the force of the bug on the tooth was equal to the force of the tooth on the bug! \n\nNo way did the two equal forces cancel, after all, his tooth was hammered to splinters, and the bug was flattened. They were equal and opposite, but since one was on the tooth, and the other force was on the bug they did serious damage! Today we call this the "HELP I'M A BUG" law.\n\nNow our man 'Zack was all set. He wrote down his three laws:\n\nTHE HAT LAW (beeep! beeep! Move it Hat Guy!)\nTHE YOU BIG BULLY LAW (betcha can't kno

This can be answered very, very simply.\n\nRelativity works well in  in it's area of expertise, astronomy and space science.  Basically, the scientists took the answers (how the planets revolve around the Sun, the Mass of the planets and stars, how the stars and galaxies move) and created an elegant series of equations to explain them all.  They believed their equations to be correct because this is what they were observing, so it must be true right?\n\nWell no, as we built better telescopes we began witnessing objects and entire galaxies moving far too fast for their observed mass, defying the equations and defying gravity!  It wasn't light pressure robbing these celestial objects of a few arc seconds, which is what sprung Einstein to whop up Relativity.  Venus was so much of a mystery, but Einstein cracked it, right?\n\nWRONG!  If the atom doesn't fit, you must aquit!  Electromagnetic forces have been known to cause these very same effects we witness the galaxies doing.  If the astronomers can't explain something they see, they blame it on magnetics.  Double-helix galaxies, just like our DNA, are floating around out there.  That should tell you where you should start looking to explain the molecular and Universal connection.\n\nVenus' orbit is nearly a perfect circle, and it spins the other direction very slowly.  It used to be called the hairy planet, the smoky planet, and bearded planet.  It's latin name means morning star.  It was literally glowing!  I'm sure some electromagnetic stuff was going on with it, and that would help explain it's brand spanking new surface.\n\nhttp://answers.yahoo.com/question/index;_ylt=AuzSsKSIJO_WapqWQB7tQcPsy6IX?qid=20060612222952AAFdmeo\n\nMars got blown the hell up.  That's a start on finding out about it right there, google should take you the rest of the way.  Hope this helped you understand why those two theories will never be united.  One of them, relativity, was based on a few wrong assumptions.

I think your mind is already made up. I would guess that you are not interested in hearing from all camps. But lets just look at some of the other scientific theories that have become the dominant accepted theories. Don't they all sound like bunk, especially if you put yourself in the position of someone who is hearing them for the first time?\n\n1. the earth goes around the sun\n2. The planets are bodies like earth\n3. the continents move and collide to make mountains\n4. the magnetic field of the earth flips\n5. heavy things and light things fall at the same rate\n6. there are simple algebraic rules that the orbits of the planets obey\n7. There is evidence for a big bang\n8. stars are not only receding from us on average, but this movement is accelerating\n9. magnetism and electricity are deeply related\n10. matter is made up of tiny pieces \n11. light has no weight but it produces pressure\n12. there are some species with 3 sexes or even 4 sexes\n13. gravity bends light\n14. if you go faster, time slows down and you get shorter, front to back\n15. a cat can be alive and dead at the same time\n16. the vacuum is full of stuff that disappears before you can see it\n17. teleportation has been demonstrated\n18. you can never locate an electron\n19. all creatures contain a list of instructions for how they function inside\n20. human instructions are quite similar to other animal's instructions and even share something in common with the instructions of some plants\n\n\nI could of course go on and on and make a list of thousands of these. They all sound like nonsense, and probably were very outrageous when they were first announced or proposed. Yet they are all accepted as true, or probably true. \n\nSo just based on your own naive intuition and or something someone else told you based on no facts at all, you are willing to believe something like evolution is impossible? Compared to what else is going on in the universe, evolution is NOTHING to get perturbed about. \n\nThe universe is strange.\n\nAs J. B. S. Haldane said, \n\nThe universe is not only stranger than you know, it is stranger than you CAN know.

Not his original, but the image in the middle of the first link I'm listing is pretty close to Descartes' from De Meteorologica.  The second source has several modern takes on the image as well as a nice physical explanation of what is going on.

Its nice to see one of many brave souls questioning the possibility of extra-terrestrial INTELLIGENT life forms. If your interested, Ive just completed a answer segment to a question posed recently and is still open... Question:: 'the latest UFO sighting observed ?'...this is a quite lengthy answer with sources provided for your further investigation if you wish! I hope it stimulates the remaining 90% of our Human Brain that is still 'A sleeping Giant'(only 10% of our brain capacity is used at GENIUS level!)

That would be Einstein's Special Theory of Relativity.\n\nhttp://science.howstuffworks.com/relativity3.htm

Yes. Key example, the Copernican theories. He was the first to "theorize" that the Earth revolved around the sun, but the Catholic Church thought this to be a "conspiracy" against the Church. As we all know, Copernicus turned out to be correct, and his 99% theory beat out the Church's 1% conspiracy, to become 100% fact.

Hubble discovered expansion...sort of. He proposed it as a theory but it was a colleague who did the math and proved it. I can't remember the colleague's name.

They were all early scientists who had different theories on the solar system. Copernicus thought it to be heliocentric, revolving around the sun, and Galileo and Newton thought the universe was geocentric, revolving around earth.

He observed sun spots moving on the surface of the sun. All of them moved in the same direction, just as similar things on the surface of the Earth would do. \n\nIt may be of some interest to note that this was only an inference from the evidence. A very convincing inference and enough, wiht some other things, to cause trouble with the Church. Direct evidence of the sun's rotation came rather later, with photography and better telescopes, and somewhat later, Doppler spectroscopy. \n\nSince Galileo is thought to have lost his sight at least in part because of his solar observations (quite dangerous to look directly at the Sun, but it's still more dangerous to look at it directly through a telescope), these later observational techniques probably saved a goodly number of eyes.

I think the truest indication of Newton's genius was his discovery (not exactly intuitive) that the same force that causes an object to fall to the ground was none other than the same force that keeps the moon and planets in their orbits.
