Is there any possibility of coming up with physical measurements that will ever tell us any thing about the universe before the big bang? I can not think of any.

Currently, it is not possible to directly explore the universe before the Big Bang because the laws of physics as we know them break down at the moment of the Big Bang. However, scientists use mathematical models and observations from the early universe to make educated guesses about what may have happened before the Big Bang.
One piece of evidence is the cosmic microwave background (CMB) radiation, which is leftover radiation from the early universe. It shows a nearly uniform distribution of matter, which suggests that the universe underwent a period of rapid expansion called inflation. This supports the idea of a universe before the Big Bang.
It is unlikely that we will ever have a complete understanding of what happened before the Big Bang. As mentioned, the laws of physics break down at this point, making it difficult to make concrete predictions. However, advancements in technology and new theories may allow us to gain a better understanding in the future.
Yes, there are several alternative theories that attempt to explain the origins of the universe. Some propose that the Big Bang was not the beginning of the universe, but rather one event in an infinite cycle of universes. Others suggest that the universe has always existed in a steady state. However, the Big Bang theory is currently the most widely accepted explanation.
Studying the universe before the Big Bang can provide valuable insights into the origins of our universe and help us understand the fundamental laws of physics. It also allows us to explore the possibility of other universes and alternative theories of the origins of the universe. Ultimately, it can lead to a deeper understanding of our place in the universe and our existence as a whole.
