No, the hot Big Bang is not in the future. The expansion of the universe, as described by the theory of cosmological expansion, does not mean that the universe is expanding into the past or the future. Instead, it means that the distances between galaxies and other cosmic objects are increasing over time.
The concept of the hot Big Bang refers to the early state of the universe, where it was extremely hot and dense. According to the prevailing cosmological model, known as the Big Bang theory, the universe began from a singularity and has been expanding since then. The hot Big Bang occurred approximately 13.8 billion years ago, marking the beginning of the expansion.
As time progresses, the universe continues to expand, with galaxies moving away from each other. However, it is important to note that the expansion does not imply that the universe is expanding into anything or that it has a boundary in space. Instead, it is the space itself that is expanding.
Therefore, the hot Big Bang is considered to be a past event in the history of the universe, not a future one.
