Wait a second are we having some sly jerk off contest here where you tell me I'm wrong, say the same exact thing I said with the only difference being that you said it instead of me, then feel like you have a big dick when everyone agrees with you instead of me?

If gravity is the result of space itself being dilated by mass is common grade school shit, then please tell me some more about it, because its hard for me to wrap my head around, and for most physicists to wrap their head around as well, so if you have some sort of knowledge on the subject which would help illustrate its simplicity, I encourage you to share it

Looking in to theoretical physics and expecting any practical application to come from it is a lot like buying lottery tickets and expecting to win.. It takes no prior qualifications to become knowledgeable in theoretical physics, but it's not a harness-able trade skill either. If you show an interest in it and have a keen inventive mind, you can become good at it, but your chance of ever having a use for the knowledge other than something cool to tell people at parties is about as good as it is for winning the lottery.
Einstein was a clerk at a patent office before he published the theory of relativity; most of the great experiments conducted in the late 19th and early 20th century which lead to our modern understanding of physics were conducted at home with crude materials. Some of those people who may have been thought of as childish quacks conducting quackery in their shed at odd hours went on to have their work ultimately contribute to the creation of things like the atomic bomb.
I'd ask you to show a little respect and keep that in mind the next time you look at these topics and think they are somehow foolish or beneath you.Last edited by Plug Drugs; 01-08-2014 at 04:40 AM.

There's this really terrible new-age movie called "What the bleep do we know" and there's this scene showing a famous experiment in quantum physics called the double slit experiment. They actually did a good job showing the basic layout of the experiment, even though the rest of the movie was shit, but then they ended it by making it out as having mystical implications..
If you want to start a cult and make a killing, write a book on physics talking all about possible implications while talking very little about things that have actually been tested out firsthand in experiments.

The cool thing about Einstein's relativity is that you can arrive at an understanding of it and deduce its validity with nothing but logic alone.. Relativity was just a thought experiment proposed by Einstein for years before there was ever actually any experimental evidence supporting it.
Einstein and company had to try and make a visit to a solar eclipse at the exact location it was visible in order to back relativity with experimental evidence; and in the early 1900s, that's a lot more difficult than it sounds. There was no air travel and they had to zig zag through international borders of countries at war with each other and travel halfway around the globe to get to the right location and be there at the right time, and cross their fingers that it wasn't cloudy.
They did all that to gather experimental evidence for something that would probably sound pretty quacky if you tried explaining to a layperson why you were traveling halfway around the globe to catch a solar eclipse.Last edited by Plug Drugs; 01-08-2014 at 05:09 AM.

Here's the thought experiment which lead to special relativity:
"...a paradox upon which I had already hit at the age of sixteen: If I pursue a beam of light with the velocity c (velocity of light in a vacuum), I should observe such a beam of light as an electromagnetic field at rest though spatially oscillating. There seems to be no such thing, however, neither on the basis of experience nor according to Maxwell's equations. From the very beginning it appeared to me intuitively clear that, judged from the standpoint of such an observer, everything would have to happen according to the same laws as for an observer who, relative to the earth, was at rest. For how should the first observer know or be able to determine, that he is in a state of fast uniform motion? One sees in this paradox the germ of the special relativity theory is already contained."

Basically, to be chasing after a beam of light at the same speed that it's traveling would require simultaneity between the observer and the beam of light, which can't exist according to special relativity.

And in order for an object to accelerate to the speed of light, the energy required is infinite.
If you were traveling at the speed of light and turned on a flash light, how fast would the light emitted from the flashlight be traveling? Such a scenario can't exist, because the concept of "space" is illusory. You can not travel faster than the speed of light because the speed which light travels at is a part of the innate mechanics of space itself that give value to notions like "speed" or "distance" in the first place. To be traveling faster than light would be to travel faster than the very thing giving 'traveling' any metric to begin with.
This also leads to the conclusion that the speed of light is always locally constant.Last edited by Plug Drugs; 01-08-2014 at 05:45 AM.

Once you finally have your head wrapped around that, go back and take a look at something like gravity which according to Newtonian physics violates every single thing you just got done wrapping your head around..
Start off first of all by throwing out the Newtonian notion that gravity's effect is instantaneous; if no information, interaction between particles, or relation between anything and anything can travel faster than the speed of light, then gravity has to be traveling at either equal to or less than the speed of light. Well what is gravity? Newtonian physics made it out as an invisible connection tethering all matter together, with pulling on one particle having an instant gravitational effect on another particle. The more you think about it, the more that concept seems ridiculous, since if gravitational interactions occurred instantaneously, then all particles in the gravitational system would be stagnate/unchanging, since any inertia given to one particle would have an instant and equally distributed effect on all particles it was tethered to, and no change in position between the particles would ever occur at all.
So what causes gravity? If we go back to the thought experiment mentioned earlier that lead to special relativity, it ultimately forces a person to give their concept of space a complete overhaul. The phenomenon of space and time are intertwined as spacetime, which can be thought of as a cosmic byproduct produced by the nature of light and energy.
Gravity results due to the presence of matter dilating spacetime; the reason matter does this can be attributed to the fundamental differences between light and matter.Last edited by Plug Drugs; 01-08-2014 at 06:08 AM.

Light requires time to propagate, even though nothing can travel faster than it.
No objects have values of location or velocity outside of their relation to other objects, and simultaneity between two different events isn't possible.

Here's a good thought experiment I thought of that makes you think about gravity and the nature of objects in motion:
When you jump up in the air, the Earth is beneath you when it lands. No matter how high you jump, the location you jumped from will be beneath you considering you jumped at rest relative to the Earth.. but what if you hypothetically jumped straight up hundreds of kilometers? Is the location on Earth that you jumped from still going to be directly beneath you? If it's always directly beneath you, and the Earth is rotating, wouldn't that from the frame of reference of everything else in the solar system, you'd appear to be flying around the Earth in a circle at impossible speeds, completing a distance of one circle around the Earth along with the Earth as it makes a full rotation?
That can't happen.. can it? Well, it actually does happen - it's happening to objects in orbit around the Earth right now. The reason that the same spot on the Earth below doesn't stay the same for, say, a spacecraft in orbit above Earth, is because the velocity required to stay in orbit around the Earth without falling back down to it changes depending on altitude, and your relative velocity with the rotation of the Earth that you had initially after jumping accounts for less and less of the velocity required to stay in orbit the higher up you get.
For spacecraft taking off from Earth, their trajectory upwards from the Earth into space will appear as a curved path going with the Earth's rotation due to Earth's gravity, as if what we proposed earlier is actually true! =) But, due to the increase in velocity required to keep the spacecraft in orbit, the location that is directly below it on Earth ends up changing.

Edited the above post so it actually makes sense when read:
Here's a good thought experiment I thought of that makes you think about gravity and the nature of objects in motion:
When you jump straight up in the air, you more or less land in the same spot you jumped from - No matter how high you jump, the spot you jumped from should be beneath you considering you jumped at rest relative to the Earth.. but what if you hypothetically jumped straight up hundreds of kilometers? Is the location on Earth that you jumped from still going to be directly beneath you? If it's always directly beneath you, and the Earth is rotating, wouldn't that appear to everything else in the solar system as flying around the Earth in a circle at impossible speeds, completing a distance of one circle around the Earth in the same time as Earth making a full rotation?
That can't happen.. can it? Well, it actually does happen, but not like that - it happened to objects in orbit around the Earth when they initially launched off. However, due to the spacecraft having to continuously accelerate to escape Earth's orbit and not fall back down to it, the spot on Earth directly below you changes with the ship's change in velocity. However, if you hypothetically jumped up 300km into space, and we eliminated factors like air/wind and not being able to jump 'perfectly straight up', and if the speed you're jumping into the air at doesn't exceed the Earth's escape velocity, you will land in the same spot you jumped from.

I don't think that "quantum physics proves that God exists!" or any of that other nutjob stuff; I like to appreciate the math of it, I like my physics and science served cold.
There's been a few nuts out there who turned around and made nutjob books on quantum physics almost making it out to be a religion, and to be perfectly honest they probably made a killing from it whilst not actually having a clue if what they were saying could be backed by any kind of evidence.Last edited by Plug Drugs; 01-08-2014 at 04:46 AM.

I still don't understand what this has to do with pushing shopping carts or threatening suicide on tinychat. I wonder if those can be explain by physics?

do you know what I'm really doing half the time? I'm piecing together how much everyone else knows about these things to figure out how much knowledge is already common, and the other half of the time I'm trying to lure someone in who knows more than I do so they can help me improve my knowledge of these topics by pointing out where I'm wrong. Most of the time I'm just babbling though and it's noise coming out of my head, down my arms, and through the keyboard
