1. The Red Planet has two different
faces.
One side of Mars is known for looking
beat up, while another side of the
planet is almost completely smooth.
The Northern side of Mars is known
for plains, while the Southern side has
a thicker crust, rockier terrain, and a
lot of craters. Why does Mars have
such different faces on the Northern
and Southern halves of it? Scientists
are still trying to find out the real
reason why.
2. When the universe was first
created, it was hot.
Temperature-wise, the universe was
very warm when it first came into
existence. Within minutes of its
creation, scientists believe that the
universe reached temperatures of over
1 billion degrees Kelvin. It cooled
down continuously until this very day,
when the average temperature of the
universe is a mere 2.275 degrees
Kelvin. It will continue to get colder in
the universe until it reaches an
average temperature of 0 degrees
Kelvin also known as absolute zero.
This is why many scientists believe the
end to our universe will be a Big
Freeze.
3. Our universe is about 13.7 billion
years old.
Scientists have confirmed that there is
nothing in the universe that is older
than 13.7 billion years making our
planet (which is about 6 billion years
old) a spring chicken in comparison.
And here we were, thinking that WE
feel old!
4. Our universe is expanding
rapidly!
Right now, scientists are amazed to
see that galaxies and the planets that
inhabit them are floating away from
one another at increasingly rapid
rates. This is also proof of the increase
in the universes expansion. Moreover,
since the universe is currently
expanding, there is no way to figure
out where the center of the universe
is.
5. Scientists are studying structures
smaller than an atom in order to
learn more about the universe as a
whole.
Scientists want to figure out what the
universe was like during the time right
before the Big Bang, which
incidentally, had conditions that are -
small.

I just wanted to ask:-
Is there any cold stars out in the galaxy? What is infinite density? (infinite!!!)
