I'm a normal adult male (abt 6ft tall, 180 pounds), if my density was that of the mean density of the universe, what would be my volume?

Astronomy is the study of celestial objects and phenomena such as planets, stars, galaxies, and black holes. Astrophysics, on the other hand, combines the principles of physics and astronomy to understand the physical properties and behavior of these celestial objects.
Dark matter is a hypothetical type of matter that does not emit or interact with light, making it invisible to telescopes. It is believed to make up about 85% of the total matter in the universe and is crucial in explaining the motions of galaxies and the structure of the universe.
Scientists use a variety of methods to determine the age of the universe, including measuring the brightness and distance of distant galaxies, studying cosmic microwave background radiation, and analyzing the composition of stars and other celestial objects.
There is currently no concrete evidence of life existing on other planets, but scientists believe that there are many planets in our galaxy and beyond that may have the necessary conditions for life to exist. Future missions and advancements in technology may help us find the answer to this question.
The ultimate fate of the universe is still a topic of debate among scientists, but some theories suggest that the universe will continue to expand forever, while others propose a "Big Crunch" scenario where the universe will eventually collapse in on itself. More research and observations are needed to determine the fate of our universe.
