Universe may hold 10 times more galaxies than once thought
Why don’t we see them? It may be a combination of our limited technology with the evolution of the universe itself. We can only do so much to account for redshifting (the light effect as objects move further away) and interference like cosmic gas, and that’s before accounting for the ever-changing nature of the cosmos. At least the data may help answer a key riddle. The shrinking number of galaxies supports the theory that galactic mergers are shaping the universe, radically reducing the overall galaxy count as more and more collisions take place.It could be a long while before it’s possible to directly verify these calculations. There may need to be a dramatic improvement in telescope technology. And remember, even the 2 trillion figure likely doesn’t represent the whole universe. The very nature of light limits our ability to see the whole of existence — it’s possible that there are many, many more galaxies lurking out of range.
