We now know that the world has existed for billions of years,
for - perspectival knowing - example - age of the world - number of galaxies
perspectival knowing - example - age of the world - number of galaxies - This may be truth for one person, but not another - Our writing reveals our perspectives, and also determines who will or will not resonate with it
This new image is gorgeous, no doubt. Its beauty is also functional, because it can help answer modern questions about how galaxies morph over time. About 25 percent of all galaxies are currently merging with others, and even more are probably gravitationally interacting, according to the Harvard and Smithsonian Center for Astrophysics.
Amazing!
And it's this process, the gravitational dance of 100,000 galaxies swirling together, 00:05:25 which drive the process of galaxies colliding, which drive massive star formation, which drive the process of creating the iron that courses through each one of our veins with every heartbeat.
For a deeper explanation outside of the TED Talk format, it would be enlightening to unpack a bit of the science behind how astronomers come to these conclusions.
