Universe Expanding Questions?

The universe isn't actually expanding at all. The idea that it does comes from misinterpreting galactic redshifts as a doppler effect when they are actually a scattering effect. The galaxies are not generally receding from each other at all. Their light simply loses energy through it's interaction with the intergalactic medium... http://www.newtonphysics.on.ca/hubble/index.html

If the universe was expanding quasars would show time dilation effects but they don't:

1 - that is incorrect. A yard stick, for example, will stay the same length because of the electrostatic forces holding the atoms together. Galaxy clusters, however, expand because they're far enough away from each other that the expansion force of the univese overpowers all other forces. All other forces decrease with distance, but the expansion force of the universe increases with distance. At some point, therefore, things will start to expand. But not until that point is reached.

2 - Space expands, not matter.

1. The Universe is the thing that's expanding. The Earth is exactly the same size that it was thousands of years ago. We're not expanding. Pretty much as if you put a sesame seed on the outside of a balloon while inflating the balloon. While the balloon gets bigger, the seed stays the same.

2. No, it's just space.

-The metric expansion of space is the increase of the distance between two distant parts of the universe with time. It is an intrinsic expansion whereby the scale of space itself is changed. That is, a metric expansion is defined by an increase in distance between parts of the universe even without those parts "moving" anywhere. This is not the same as any usual concept of motion, or any kind of expansion of objects "outward" into other "preexisting" space, or any kind of explosion of matter which is commonly experienced on earth.-

We know because on large scales objects are 'Red Shifting' That is to say they are moving away from us. The measurement we use is constant - the vairable is the distance. So for example One metre is still a meter and one AU is still one AU (Astronomical unit)

No mass does not expand - the space between particles will but not the particles themselves they are held together by their Strong force.

1,2 The expansion of space really only affects the space between galaxies. Almost everything else has enough gravity to overcome the expansion of space.

For instance, you are not expanding.

a needed factor is that area itself can strengthen swifter than the fee of sunshine. the fee of sunshine does not substitute moving via area. it is the inspiration of inflationary cosmology.
