At the same time, theorists have made a series of predictions to be tested when and if observations of the CMB could be improved further still.One idea first proposed in the 1980s suggests that during its first instants of existence, our Universe underwent an episode called inflation, during which space itself expanded at a ferocious rate – ‘the bang of the Big Bang’, as one of its inventors, the theoretical physicist Alan Guth at the Massachusetts Institute of Technology, describes it.That’s how matters stood for almost three decades until 1989, when a specialised telescope called the Cosmic Background Explorer was launched into Earth orbit.

So much has been discovered about that seemingly inaccessible time and process because the Big Bang – the explosive appearance of space and time, matter and energy, essentially out of nothing – left a snapshot of itself in a flash of light called the Cosmic Microwave Background (CMB).But observing at the ragged edge of technology is always a tricky business.The tiny fluctuations the BICEP2 team found within their data – the signal they claimed was the signature of inflation’s gravity waves – quickly drew informed scrutiny.What is known to date is that the BICEP2 results do not contain a reliable observation of inflation’s signature in the CMB. Several attempts are already underway to probe the CMB with yet more precision.Those measurements will likely settle whether the predicted gravity waves really do reveal themselves in the microwave background, and even if the hoped-for polarisation effects are not found, there are versions of inflation theory that do not require a gravity wave signature in the ancient glow of the Big Bang.
