How universe developed observe structure from featureless hot cluster of particles?
Astronomers attempt to calculate amount of matter they see in galaxies today managed to pull together by gravity.
Computer models of galaxy formation take longer to form than time in actual universe.
Add question to models:
Inflationary Universe: show universe consist invisible matter in unknown form.
- Proven by motion of stars in galaxies, of galaxies in galaxy clusters.
Inflationary Theory- attempts to combine particle physics (science of smallest particles, with cosmology, the study of universe at largest scale size).
Predicted amazing behavior in the first 10-30 sec.
Began as submicroscopic bubble, double in size and so on for 50-100 doublings, no longer than 10-30 sec.
Behave like normal expanding universe today.
