Scientists have been attempting to monitor (“listen”) to the cosmic background radiation of the universe, which is the residual radiation from the Big Bang. There have been new developments and advances in this field, and one of these advances is the detection and study of gravitational waves by the Ligo and Virgo projects. Scientists are now taking into consideration the study of both low and high frequencies of waves, as opposed to mainly studying low frequencies. The new devices that would need to be made and used to detect high frequencies would likely be smaller in size and more economical, although the detection of high-frequency waves remains a difficult task.
Key Takeaways:
- The estimated beginning of our known universe, 14 billion years ago, remains a mystery of physics.
- It’s been proposed that in its earliest pre-big bang days the universe was filled with a gaseous dense plasma.
- This pre-bang plasma was full to the brim with charged particles, specifically electrons, and protons.
“Now several projects are trying to listen to the big bang using gravitational waves – ripples in the very fabric of spacetime. Our new project will aim to detect such waves at ultra-high frequencies, and could lead to the discovery of brand new physics.”
