Mt. Nixion said:I don't know about you, but I know that everything has limits. So I have a question; Is the universe just three dimensions plus time and contain just the forces, energies, and laws of physics that we know about; or is there more dimensions and physics laws, energies and forces that are in this universe and cannot be perceived by our senses or visualized?
The universe is the entirety of space, time, matter, and energy. It includes all planets, stars, galaxies, and other forms of matter and energy.
The universe is estimated to be about 13.8 billion years old. This age is determined through various scientific methods, such as studying the expansion of the universe and the cosmic microwave background radiation.
The Big Bang theory is the prevailing scientific explanation for the origin of the universe. It suggests that the universe began as a singularity, a point of infinite density and temperature, and has been expanding and cooling ever since.
The observable universe, which is the part of the universe that we can see, is estimated to be about 93 billion light-years in diameter. However, the actual size of the entire universe is still unknown and may be infinite.
The question of whether there is life in the universe is still a topic of scientific debate. While there is currently no definitive evidence of extraterrestrial life, many scientists believe that it is possible, if not likely, given the vast size and diversity of the universe.
