Answer:
No
Explanation:
Our universe is not the size of a grain of sand. A grain of sand is approximately 2 millimeters while the size of the universe is approximate 93 billion light years in diameter and recently estimated to be 250 times 93 billion light years which is at least 7 trillion light years.
Light-year is a unit of length used to show astronomical distances.
1 light-year is exactly 9460730472580800 meters.
Comparing the size of a grain of sand to that of the universe,
2 millimeters = 0.002 meters and
9460730472580800 meters = 9.460730472580800 e+18
