Galaxies occupy approximately 2% of the universe.
Galaxies occupy approximately 2% of the universe.
To determine the percentage of the universe that galaxies occupy, we can use the concept of the observable universe. The observable universe is the portion of the universe that we can see or detect from Earth.
Scientists estimate that there are about 100 billion galaxies in the observable universe. However, it is important to note that the universe is believed to be much larger and may contain an even greater number of galaxies beyond our detection.
Given this information, we can calculate the approximate percentage as follows:
(Number of galaxies / Total estimated number of galaxies in the observable universe) x 100
Plugging in the numbers, we get:
(100 billion / Total estimated number of galaxies in the observable universe) x 100
Now, since the choices you provided are given in whole numbers, we can round our result to the nearest whole number.
1. 5%: This is not the correct answer because it is not within the given choices.
2. 2%: This is a possible answer.
3. 10%: This is a possible answer.
4. 20%: This is not the correct answer because it is not within the given choices.
To find the exact percentage, we would need to know the estimated total number of galaxies in the observable universe. However, based on the given choices, either 2% or 10% could be considered approximate percentages for the portion of the universe occupied by galaxies.
