Gravity - From Newton to Einstein - The Elegant Universe
About | Information | History | Online | Facts | Discovery
This clip is taken from the NOVA PBS series "THE ELEGANT UNIVERSE' and is used under the provisions of the Digital Millineum Copyright Act of 1998 (Title IV). Brian Greene guides us through Newton's discovery of gravity to the explanation of it, through Einsteins Theory of Relativity. Brian Greene is a theoretical physicist and one of the best-known string theorists. Since 1996 he has been a professor at Columbia University. The Elegant Universe was adapted for a three hour program in three parts for television broadcast in late 2003 on the PBS series NOVA. http://www.pbs.org/wgbh/nova/elegant/

Einstein = the god of the religion scientism

The uniform accelartion produced in a freely falling body due to the gravitational force of thr earth is called the acceleration due to gravity and it is denoted by the letter "G"
The acceleration due to gravity is always directed vertically downwards ie towards the centre of the earth
The value of G does not depend on the mass of the boardy
The value of g changes slightly from place 2 place most of its taken as 9.8 m/s2
At the centre of earth the value of g becomes 0 -
in 8 mins/ speed of light

my theory of space and time
fabric of time and space = multiverse -
Heres a test. can anyone tell me who/what created/caused gravity? im not talking about Albert Einstien, or issacc newton, they were just theorists/scientists. answer my test.

So what the hell is space? Time?
-
Space is teeming with subatomic particles, so the bend might be due to an interaction... Even we bend space right
-
but of the sun will disappear the earth at that time lives it's orbit or after some time ????
-
space and time are one in the same. they would not exist without eachother yet where there is mass (planets,moons,black holes, etc) gravity and time is distorted, so spacetime bends and time and space change.
(special relativity in nutshell) -
how the fudge does space and time have a fabric
-
One and only mistake is that we live on the geocentric earth

5:08 You got to know matter can not be fully destroyed. The essence of the material that the sun is made of is still going to be there. Look at burning a log as an example. Although the log is burned up the material that the log is made of survives. It either turns to ash or it goes up in to the atmosphere as a gas. Although the sun burns all of it's flammable gasses the gas is transferred into another gas. Hydrogen to helium in this case. That mass of gas is going to keep the planets right where they are at. Got to look at my theory on my other comment to understand why that mass of gasses will still keep the planets right where they are at. They already seen galaxies that the sun was burned out and it's planets was still revolving around a black hole. Not really a black hole but just black because the sun was burned out.

Einstein was wrong. Light is photons and Electrons are faster than photons.

This is my Theory of Gravity. Mass has energy. Every bit of mass even matter in the gas form has energy. Movement is a form of energy so every form of matter has other smaller particles circling around a nucleolus "Atom" That movement is energy. We all know opposites attracts and similars repel. So smaller objects with less mass "less energy" is going to be pulls towards bigger objects with more mass "more energy".Einstein's talk about space being a fabric and this is why we have gravity is just hogwash to me. What happens when we leave the earth at the bottom where it is suppose to be resting on this so called fabric? Is it going to puncture this fabric and create a black hole? Just hogwash to me. My theory sound more plausible to me. I think this and Newton's theory are the same and my Theory explain Newton's law more precise than this hogwash Einstein came up with.

Life would not exist without gravity, we measure it precisely but have NO Clue to How It Works. We can only imagine a possible way that has no foundation

Sorry dud fabric of space and time is stupidity to the core. To be honest I haven't seen nor accepted a single experiment which proves the speed of light.

A short prayer: God, please forgive F.A.M.Z. for he knows not what he writes. In fact, he simply knows not.
