So after reading all this I now understand:
a) If you travel faster than light then you cannot see in the same way that when you travel faster than sound you cannot hear. b) Time must constant and the concept of relative time is anathema despite absolute proof being demonstrated on many occasions by many different persons. Relativity: If you are walking down the aisle of a 747 is flight how fast are you going? To those in the 747 you are going slow, to those on the ground you are going fast. The axiom that you cannot exceed the speed of light is more accurately stated that "You cannot perceive a velocity differential between two objects that exceeds the speed of light". Object A goes north at 100km/h, object B goes south at 100km/h, relative speed 200km/h. Object A goes north at 0.6 times the speed of light, object B goes south at 0.6 times the speed of light. What is the relative velocity? No it is not 1.2C, nor is it 1.0C. It is different depending on what it is passing through at the time. Then there is the quantam component. If a GT Falcon is seen at a point at 2PM and is seen at another point 100km/h away at 3pm how fast did it go to get there? 100km/h? What if the road was actually 170km long with lots of bends? What if 100km is the road length and the two points are 1km apart in a straight line? This can be quite complex stuff.............. http://forum.physorg.com/ P.S. I do not think there is a section in it on modding FPVs........ |

Someone mention time travel, Valeriy Polyakov, russian cosmonaut apparently came back to earth somthing like 0.005 of a second ahead of time because of the time he spent orbiting earth at a faster rate then earths orbit.

traveling at the speed of light will one day be possible but will be a few hundred years off me thinks,
as for moving object at the speed of light humans have done it i remeber reading it somewhere, somewhere in europe or something have done it. so it is possible

Love this stuff 'What man can imagine, man can do' , I reckon this saying definately rings true. Hey it's gold looking at the night sky and thinking u could be witnessing a star or event that happened when he dinosaurs ruled the Earth.
Read a crazy UFO Theory novel a year ago. The author (proffessor of some sorts) theorizes that we were visited thousands of years back by intelligent life which are now interpreted 'gods'. Ancient texts speak of 'gods' being 700 hundrered years of age etc. Using the speed of light quirks mentioned above he explains how this could be possible with advanced beings who have mastered time travel. lol. Such facinating stuff the working of space, time, and theoies cahllenging the mind and conciousness, where does space end etc, also nothing more frustrating than having the curiosity but not the IQ to fully understand these things. Gotta love SBS doco's for this sorta gear. |

Nothing can travel at the speed of light that has mass. Only photons.
That was the rest of Einstiens theory.

If you didn't run in a straight line you'd see yourself, in places, because you've allowed the light to travel uninterupted. Last edited by monkeydog; 19-08-2007 at 04:47 PM. |

What theory is that? I'm not too sure where you're coming from. If light isn't reflected it is absorbed and converted; that's fact.

Typical.
It took German scientists to get Nasa on the Moon and now it'll take german scientist to go faster than the speed of light. Whats next? A cure for the Common Cold?

A photon is neither energy nor particle. It is a photon. It has no mass.

The arguement goes something like this:
"I refuse to prove that I exist," says God, "for proof denies faith, and without faith I am nothing." "But," say Man, "the Babel fish is a dead giveaway, isn't it? It could not have evolved by chance. It proves you exist, and so therefore, by your own arguments, you don't. QED." "Oh dear," says God, "I hadn't though of that" and promply vanishes in a puff of logic. Regards Slartibartfast Magrathean Designer of Planets

Yeah sure, while I'm at it would you like me to explain the theory of evoloution. How about sub atomic theory. Photons have no mass at rest. (this is high school physics by the way, proposing that photons have mass at rest is highly theoretical and totally unproven) ![]()

They now need to work out how to stop in time. There's enough space junk in our skies without it being full of Germans who've overshot on the Cologne to Frankfurt run.

At least when kids need to go to the toilet on trips and parents go 'you should have gone before you left', it's not too late.

Its true enough alright I learnt about it years ago proving that RF energy in a waveguide (Radar Theory) does infact travel faster then the speed of light. Its only possible whilst the engery is inside the waveguide and at a high enough level ie 10kw or more.
It like Flappist said it all comes back to mass and inertia.

that a pretty easy to understand, i didnt have a problem with it. learnt all bout this in year 8 physics
lol im joking too, only read about 1 paragraph and i was lost

when you look in the mirror you do not see the real image of yourself at that time, but rather a younger you. so, why bother?

Wouldn't that be all over media and such? It hasn't. Which means its only in the minds of those who STILL believe in Albert Einsteins "SPECIAL" theory of relativity, which is not so much special anymore, for the fact that more smarter people (not him from 1905 but from now 2007) have PROVEN his theories wrong. |

Newton thought that only objects with mass could produce a gravitational force on each other. Applying Newton's theory of gravity, one would conclude that since light has no mass, the force of gravity couldn't affect it. Einstein discovered that the situation is a bit more complicated than that. First he discovered that gravity is produced by a curved space-time. Then Einstein theorized that the mass and radius of an object (its compactness) actually curves space-time. Mass is linked to space in a way that physicists today still do not completely understand. However, we know that the stronger the gravitational field of an object, the more the space around the object is curved. In other words, straight lines are no longer straight if exposed to a strong gravitational field; instead, they are curved. Since light ordinarily travels on a straight-line path, light follows a curved path if it passes through a strong gravitational field. This is what is meant by "curved space," and this is why light becomes trapped in a black hole. In the 1920's Sir Arthur Eddington proved Einstein's theory when he observed starlight curve when it traveled close to the Sun. This was the first successful prediction of Einstein's General Theory of Relativity. One way to picture this effect of gravity is to imagine a piece of rubber sheeting stretched out. Imagine that you put a heavy ball in the center of the sheet. The weight of the ball will bend the surface of the sheet close to it. This is a two-dimensional picture of what gravity does to space in three dimensions. Now take a little marble and send it rolling from one side of the rubber sheet to the other. Instead of the marble taking a straight path to the other side of the sheet, it will follow the contour of the sheet that is curved by the weight of the ball in the center. This is similar to how the gravitation field created by an object (the ball) affects light (the marble). Got this off: http://amazing-space.stsci.edu/resou...kground.html#3 Basically, the reason why light cannot escape a black hole is due to the gravity waves created by the black hole. Light travels in a straight line, and can be bent due to the presence of a gravitational field (like gravity we experience on earth). The point is, the gravitational field on a black hole is massive, hence photons(light) are pulled into the center of the black hole, and due to the strong gravitational field, cannot escape. |
