Theoretical physics scientist study how the universe was form in the first couple of trillionths of a second after the Big Bang started.
Physical astronomers look at where things are in the universe, what they are made of, where they came from, and especially what are black holes, and how do things work close to one.
Those are both poorly worded versions of the same question. The question should read:"Does the universe have nine planets?"And the answer is:"No. The Universe has trillions and trillions of planets, but our solar system has eight planets."
There are no humans in the universe other than on earth - that we know of - so nobody knows.
The concept of the first person in the universe is not scientifically quantifiable. In terms of evolutionary science, the first single-celled organisms are considered to be among the earliest forms of life on Earth. From a religious or mythological perspective, beliefs vary widely on the concept of the first human or sentient being in the universe.
No one knows that because we have not explored outside the universe. If you are thinking about the galaxy, it looks like a straight line from Earth and a circular object from outside the galaxy.
No one knows because it's 10 duotrigintillion is a googol or 10^100.
No body truly knows all the planets in the universe but ask a science teacher or a student that studies planetary science.
God did not form the universe, it was pure science! Nobody knows EXACTLY, but He used his power to do it. He can do ANYTHING>
That was onece the belief, but today science knows that there are several smaller particles.
No one knows exactly because most American Christians believe that God created our universe, but Science describes how God did it. Creationists believe that God used supernatural magic, not Science to create the Earth.
Personal knowledge is something that a person knows from first hand knowledge. It is not something that one has heard, or thinks, it is what someone knows for a fact.
Nobody knows
nobody knows but the size of the universe has been found out...
Honestly, the universe is a pretty big place. No one really knows the volume of aluminum as a percentage of the universe.
One who knows one thing that he/she knows nothing.
The universe is expanding forever and nobody really knows the length.
no body knows
no one knows
