How Big is the Universe?
The
universe is a pretty big place! It’s full of all different kind of
galaxies, stars, planets, and even more! In fact there are so many
technologies out there that help us discover such great quality from a
place right above our heads! Have you ever really taken the time and
asked yourself, how big really is the universe? Well if you have, that
question will be answered! The universe is about 13.7 billion years old,
but it has been expanding ever since the beginning of time, so no one
really knows! Scientific theories prove that there are many different
galaxies in the universe so you don’t exactly know how big it is!
Some of the Tools We Use!
This is a post about all of my tools that we use to find the location of the solar system and the Milky Way, and how they work!
Telescope-
A major tool; Helps you see far into space to get research on how
things look. There are telescopes for every part of the light spectrum,
from Gamma ray telescopes to radio telescopes. A Gamma ray telescope
detects super high energy photons that cannot be focused by a glass
lens. A radio telescope allows us to see into places optical telescopes
can't see.
Satellites- Great for gathering specific types of data as well.
More
recently, particle smashers allow us to observe conditions of the
universe shortly after the big bang. It's like an astronomers test tube.
