Have the gravity waves been detected from the big bang?

[azzkika]

I watched an interesting programme a while ago about the atom, and amongst other things relativity was quite prominent in the programme. one of einstein's predictions was that we would be able to detect gravity waves rippling across space time from the big bang, and it cited a current experiment being conducted for precisely this purpose.

i don't suppose anyone knows of this and if so, have they got the experiments' results yet and what are they??

No, they have not detected any waves yet.
Moreover, as far as I understand they are mainly focusing on trying to detect waves from e.g. colliding black holes and similar "extreme" events; this should be easier than waves from Big Bang.
Most people beliveve that current experiments are still not sensitive enough even for these extreme (and rare) events, but the next generation of detectors should be able to detect something (basically since they will be sensitive enough to detect more common events); if they don't there is something wrong with our current understanding of GW.
We should know within a few years.

The detection of gravity waves from the big bang is a topic of ongoing research and debate in the scientific community. While there have been several attempts to detect these waves, the results have been inconclusive and controversial. The most notable experiment for detecting these waves is the Laser Interferometer Gravitational-Wave Observatory (LIGO), which has been searching for gravity waves since 2002. In 2016, LIGO announced the first direct detection of gravity waves from the merger of two black holes, but this does not necessarily confirm the existence of gravity waves from the big bang.

Other experiments, such as the European Space Agency's Planck satellite, have also searched for evidence of gravity waves from the big bang, but again the results have been inconclusive. Some researchers argue that the detection of these waves would provide strong evidence for the theory of inflation, which explains the rapid expansion of the universe in its early stages.

In summary, while there have been attempts to detect gravity waves from the big bang, the results have not been conclusive and the search continues. Further research and advancements in technology may eventually lead to the detection of these elusive waves, providing valuable insights into the early universe and the theory of relativity.
