If BB is not a right answer, then what is preventing galaxies from getting closer [to] each other under effect of gavity ?

A repulsive force...


"What gravity? In a homogeneous universe the mass distribution is the same in all directions and the force of gravity cancels to zero overall."

Here is a great picture taken from Hubble of the furthest galaxy known:

"Hubble finds most distant galaxy
Last Updated Mon, 16 Feb 2004 19:01:56
SEATTLE - Scientists have found a far off galaxy they say is the farthest known object from Earth.

It took about 13 billion years for the galaxy's light to reach Earth. The galaxy first emitted the light when the universe was 750 million years old, astronomers said.

The new object appears as two thin red streaks inside the circled area (Image by Jean-Paul Kneib, Richard Ellis and NASA/ESA)

The international team discovered the distant galaxy thanks to the high resolution of the Hubble Space Telescope. Observations from W. M. Keck Telescopes in Hawaii confirmed the findings."

"Mass Shielding

In Newton's gravitation, density is always finite inside a spherical mass M but is taken to be zero outside M. This is another way of saying that M is a constant. Brillouin, however, shows that the field E of mass M always has a negative mass so that when seen from a distance, apparent mass MA is the sum of its actual mass M and negative field mass Mf...."

A picture tells a thousand words. Yet we cannot step back far enough to see what is really going on. It might be that the entire viewplane is part of a huge arm to a superuniverse. But, we only see the light traveling through a medium of space at a constant speed (light cones TILT and FTL, OR does light slow down?)for 13 billion years that shows a balanced view of many galactic clusters. Now, if the universe has rotation which I believe that it does [because at all scales you find rotation due to positive and negative reverse spin from 4d time +- interactions] then a field of resonant energy would envelope the entire universe. Our universe is not infinite in size or dimension, but most likely it always existed as a homogenous structure of a greater multi-dimensional universe.

Regarding the question of what might keep galaxies apart, a reduction of 'G' for regions of matter of high mass/radius ratio would do it.

The the high temperature and pressure would allow a 'bounce'. There is more on this in the galaxies thread, and www.gravity.uk.com

John Hunter.

Why galaxies are kept apart rether than being attracted by gravity toward each other is a very interesting detail. It must have something to do with gravity don't you think? Gravity makes clumps of matter stick together but on large scales the matter is made to orbit about other matter by the same gravity. The reason this happens is not at all clear and if anyone knows why it would be great to read about why this happens. Maybe matter only forms into clumps we call stars, planets, moons, rocks, atoms with rules nobody knows about.

Actually I think there's already a pretty good answer to why galaxies don't all join into one big lump. Tom's chapter where he discusses why asteroids and other bodies in our solar system don't catch up with each other and all lump together really probably covers the very same issue, only on a much smaller scale. As I understand it, Mr. Van Flandern was suggesting that capture occurs due to changes in an objects sphere of influence relative to another gravity field, or collision, but I understand it(perhaps incorrectly) that objects cannot be captured by simply passing close to each other. The way gravity slingshots objects past planets seems to support this. Anyone correct me if I'm wrong here...

The real reason for capture or not is angular momentum. Given enough angular momentum and capture can't happen-if the two objects have less than a critical amount of angular momentum capture will result.
