Gravitational waves due to Big Bang?

In summary, the conversation discusses the recent observed gravitational wave and its potential connection to the Big Bang. There is speculation that the merging of two black holes at the speed of light triggered the Big Bang on a larger scale, while smaller scale Big Bangs may have also occurred, such as the creation of the Moon. The conversation also mentions a high Sigma value for the matching of the black hole merger, indicating a close match between theoretical predictions and actual data. The thread is then closed as the original question has been answered.

The recent observed gravitational wave is claimed due to two merging black holes colliding or infusing into each other. Could it be just another local Big Bang? (Of course I am implying Big Bang occurs in various scales). So "our Big Bang" was a large scale Big Bang and was triggered by two immensely densed black holes merged at, say, light's speed? For another example: Moon was created for a small scale Big Bang. What's your take?

I think the Sigma for matching the merger of two black holes was something like 5.1. That means the predicted theoretical profile signature and the actual data received matched very, very closely. Think of the event profile as a kind of fingerprint, so researchers are pretty sure they know the cause of the data.

1. What are gravitational waves from the Big Bang?

Gravitational waves are ripples in the fabric of space and time, caused by massive objects moving or colliding. In the case of the Big Bang, these waves were created during the initial expansion of the universe.

2. How were gravitational waves from the Big Bang detected?

In 2015, the Laser Interferometer Gravitational-Wave Observatory (LIGO) detected gravitational waves for the first time. These waves were caused by the collision of two black holes, providing evidence for the existence of gravitational waves from the Big Bang.

3. What does the detection of gravitational waves from the Big Bang tell us about the early universe?

The detection of gravitational waves from the Big Bang supports the theory of cosmic inflation, which explains the rapid expansion of the universe in its early stages. It also provides insight into the conditions of the universe immediately after the Big Bang.

4. Are there other ways to detect gravitational waves from the Big Bang?

Yes, there are other experiments and observatories currently being developed that may be able to detect gravitational waves from the Big Bang. These include the European Space Agency's Laser Interferometer Space Antenna (LISA) and the proposed Big Bang Observer (BBO) mission.

5. What impact can the detection of gravitational waves from the Big Bang have on our understanding of the universe?

The detection of gravitational waves from the Big Bang has already provided significant insights into the early universe and the nature of gravity. It can also help us further test and refine our current theories and potentially lead to new discoveries about the origin and evolution of the universe.
