- A history of the Universe Resource
- In the beginning there was nothing at all. To the north and south of nothingness lay regions of fire and frost.
- 1 Time, space, temperature and energy Resource
- The conventional view of the Universe is that, at the very instant of the Big Bang, the Universe came into being. There was no ‘before’ this instant since the Big Bang marked the creation of time. No location...
- 2 The very early Universe Resource
- Time:
- 3 Inflation Resource
- Time: 10−36s to 10−32s
- 4 The quark-lepton era Resource
- Time: l0−11s to 10−5s
- 4.1 The quark-lepton era (contd) Resource
- The next stage of the story is to look at how and when the original mixture of all types of quark and lepton that were present when the Universe was 10−11 s old, gave rise to the Universe today, which...

- 8 Summary and questions Resource
- The Universe was created at the instant of the Big Bang. As it has aged, the Universe has cooled and distances within it have increased. At the earliest times, the four fundamental interactions were unified,...
