To conceptualize the comparison, consider that a human cell is typically around 10 micrometers in diameter. When imagining something on the scale of the universe to compare with this, we might look at the smallest units within the universe. The observable universe’s diameter is about 93 billion light-years. If we apply a similar scaling factor […]
