@biped19 So Einstein should get no credit? No one else thought to put the pieces together. If 100 people each made a part of a car, but they never came into contact, should we give them all credit for making a car? No, we shouldn't. We give credit to whoever thinks "Hey, maybe I should put all these pieces together and make something useful" and builds a car. If everyone came up with their own ideas we would be nowhere. You have to build off of others ideas and incorporate your own.

Pink Floyd! ;P

@MrIamSamIam2 Not to mention Gravity! With all respect, of course.

@tucense You are happy enough to walk, sail, drive or fly around the Earth without going in a straight line & falling off, though? Isn't that in itself a little suggestive of spatial curvature? 

[MrIamSamIam2]

@wasdare32 Especially with General relativity. That involved a conceptual leap well beyond Special Relativity. I remember an essay in which Martin Gardner discussed this & how others probably would have fit the pieces together for Special Relativity, but the idea that Inertia & Gravity were the same force was so crazy - Newton would've have thought it positively insane - that he felt some creativity beyond "mere" excellent physical intuition & the application of 19th C maths was involved.

0:58 Why is the video trying to explain gravity with a model that already assumes gravity exists. It's showing nothing but a redirection the downward pull of already existing gravity to a horizontal pull due to the normal force of a simple ramp. The orbit is not caused by space contraction.

The contraction of space would have to be continuous and always contracting at an ever increasing rate in order to accelerate the two objects closer together. It really isn't a good model..

[tucense]

@ryanduds I totally agree. I never understood the metaphor of the bending or contracting space with the planet circling, because there is assumed gravity already in the model. Space would have to be accelerating into the large mass in order to bring the planets together... unlike like the static trampoline's surface.

Orrr all objects are accelerating relatively larger.. lol

[ryanduds]

Why does the planets "fall" into the curvature of space/time from the mass the sun, would that not imply that there's a force causing it to fall? If gravity is the curvature of space/time, what makes the planets have mass and press against the fabric of space/time?

You cannot have two causes working against one another. ONE cause will be the PRIMARY cause and the initial stronger of the two [or more] effects. The effects cannot cause the original cause to do anything!

Ex. The moon is in the grasp of the cause, which is the gravity of the earth; because of earths various strengths of gravitational pull on the moon, the tides rise and fall. The moon is in effect from the earth and is suspended in eliptical orbit. The moon cannot become the cause of earth.

Present knowledge claims the universe is based on harmonic balanced Laws of Physics.

Theory: TIME AND SPACE CAN BE CURVED BY MASS What is meant by "CURVED" time and space? What physical attributes does mass have, to effect space & time in any way? What PHYSICAL ELEMENTS can accomplish these theorhetical actions?

2 Theory : The curveture of space causes mass to move?

How can mass be effected by space, since there are no sub-atomic particles or wave constituents, composing the space vacuum?

[EGMAG]

CAN SPACE AND TIME BE CURVED BY MASS?

CAN THE CURVATURE OF SPACE CAUSE MASS TO MOVE?

DON'T THESE TWO IDEAS NEUTRALIZE ONE ANOTHER?

WHILE CURVING SPACE & TIME BY MASS THE CAUSE IS MASS.

HOW CAN THE MASS BE MOVE WHEN IT HAS NOT CAUSED THE CURVITURE OF SPACE PRIMARILY YET? HOW CAN HOW CAN SPACE AND TIME BE THE PRIMARY CAUSE ALSO? ISN'T THIS A CONTRADICTION THEORY WHEN CONSIDERING APPLIED CAUSES AND EFFECTS & EFFECTS AND CAUSES?

[EGMAG]

It appears that the explanation here lacks the fact that the entire universe is truly hurtling at tremendous speed along with all celestial bodies in fluctuating times & areas of space ; therefore it is innacurate to assume measurments of space and time in a constant reformation of this universe; as is insinuated in this video. Part one.
