Newly released Hubble pics

This was interesting (Caption below photo): "The globular cluster M75 contains about 400,000 stars. It is 13 billion years old and found 67,500 light-years from us."

That globular cluster is almost as old as the Universe itself, as are most galaxies. A reminder that Galaxies formed very soon (relatively speaking) after the quark fog "froze" into baryons, and they in turn froze into atoms. I may be mistaken, but it seems that gravity must have already dominated galactic formation before the baryons erupted into being.

Gorgeous!

Without matter there is no gravity

Primordial particles and even energy, have mass, and it's the mass which causes the curvature of space (not just matter) that we measure as gravity.

So even though there was no solid Baryonic matter in the early universe, there was still the force of gravity, and there were still distortions in localized curvature due to energy and quark distribution.

The real question is why is there variation at all? Why wasn't the early universe just flat and homogenized? There are some good theories to explain this already, but I don't think any one of them yet tops the heap.

What's a primordial particle and how much mass does it have? And how much mass does energy have if it's not in a particle of matter? Or are you saying there is mass stored in the Higgs field?

Fabulous!

The furthest star observed to date.
