The shape of a water drop is irrelevant. The temperature of the universe at the big bang is also (largely) irrelevant.
The universe is 13.8 billion years years old.
The age of the sun is ~ 4.6 billion years old. The age of the earth is ~ 4.1 billion years old.
Are you suggesting the universe acted as an homogeneous liquid for something like 9 billion years, while rapidly expanding after the big bang? That simply doesn't make sense.
Are you also suggesting that surface tensions operates on non-connected particles at millions of miles of distance, over many millions of years?
