When you look at a distant galaxy through a telescope, how is it that you're looking backward in time?
The distant galaxy looks like when looking from the telescope backward in time.
Explanation of Solution
Introduction:
When we look at distant galaxy with telescope in backward time, we see how they change as they age.
The distant galaxies looked with a telescope they look like when the universe was much younger, as galaxies were first forming. As we look at closer to the galaxies, we see how they change as they age, just as looking at children, teenagers, and then adults can show how we humans change as we age.
Conclusion:
As we look at very closer galaxies, we see their changes with the age like babies, children, teenagers, and then adults can show how we humans change as we age.
