The COMPACT team has studied thecosmic microwave background(CMB) — the radiation left over from the Big Bang — looking for any patterns.They haven't found any, but there are two caveats. One is that the scale of the 3-torus could be so large that light traveling around one of its ...

Does dark matter exist? I wish I knew! W...
Is Einstein's cosmological constant behind it? There might be a way to find out. The nature of the 'dark energy' that is causing the apparent accelerated expansion of the Universe is, without doubt, the biggest mystery in physics and astronomy. Although it was astrophysical observations of ...
Not that I know of. There are some issues that arise with the simplest model of the Big Bang, but those can be resolved by invoking a physical process that is still consistent with the basic premise of the Big Bang Theory. Specifically, the fact that the CMB temperature is the same ever...
