How is this Possible?

These result COME from Einsteins Principle Postulate of Relavity

All the laws of Nature must be the same in every freely moving laboratory/reference frame.

Time and Space are Relative (or Personal)... You have your time and space and I have mine.

They are mixtures of each other and depend how each of us are moving (and where we are).

**3) Newton's Law of Gravity**

Newton's law of Gravity says that the sun attracts the earth gravitationally with a force that is inversely proportional to the distance between the earth and the sun. The separation when?

Instanteous separation.

Newton's law's depend on instantaneity and distance being absolute.

Problem is separation D is different for Sun and Earth. Simultaneous is different for sun and earth. Newtons law of gravity violates relativity.

"The Happiest Thought of My Life"

If a person falls freely, he would not feel his own weight.

Imagine you are standing in a stationary elevator. Your feet are firmly pressed on the floor, your head pushes on your shoulders and your stomach rests securely inside your body.

Now imagine you are in an elevator with the cord cut (don't worry, there is a big spring at the bottom of the fall). Since everything falls at the same rate, your feet no longer push on the floor, you head is no longer pushing on your shoulders, and your stomach floats freely in your body. In short you are weightless. It's as if gravity was turned off! An astronaut floating in space would feel exactly the same.

To be more precise, there are no experiments you could inside the falling elevator that would distinguish whether you were falling in the elevator or floating in space. Of course you would know the difference since you walked into the elevator, but that is not the point. The point is that the laws of physics are the same in both situations. This is why it is called the principle of equivalence.

The effects of gravity are exactly equivalent to the effects of acceleration.

This led Einstein to a long road to discovering first how warped time causes gravity THAN because space and time are mixed, it also had to include space. So finally in 1915 we have the General Theory of relativity that shows how space and time are warped by mass and energy.

Suppose a child throws two apples up in the air absolutely parallel.

Explore trajectories. Fall down into the earth and hit at the center.

Matter Warps Spacetime

And That Warping Causes Gravity!

**Newton says gravity did it**

Einstein said warped space-time did it.Einstein said warped space-time did it.

**5) Proof Space is Warped came in 1976**

1976 - warped space around sun.

There really is a higher dimension, and space is warped in that dimension.

bulk hyperspace contains 4d space-time (where space-time warps INTO.)

Warping of 2d needs to go into 3d.

All the warping of space and time

Einstein right to 1 part in 10,000

Gravitational Lensing

Massive Cluster of Galaxies warps

Warped space shows up in astronomy

Warping of space is a key tool for studying exotic phenomenon in the Universe.

**The Warping of Time - Shown conclusively first in 1976**

-Things like to live where they age the most slowly

-Gravity pulls them there

On earth time slows by 1 second in a 100 years compared to high altitude and that slowing of time is what holds us to the earth (gravity). Verified

That tiny amount of slowing of time cause gravity.

Gravity Probe - Prediction of general relativity is that time slows by 4 parts in 10 billion (roughly 1 second every 100 years).

Verified to .01% accuracy!!

**8) Warped Space and Time around Black Holes**

Spinning black hole drags space.

Like tornado, but instead of air space is spinning.

You cannot prevent yourself from whirling around and around.

Center of Constellation in Sagitarius center of milky way

4 million solar masses

stars wip around black hole like comets.

Black hole has to spin really fast to have planet orbit.
