Missions to Study Big Bang
There were so many missions has been conducted to study the Big Bang as mentioned below.
Cosmic Background Explorer (COBE) |
Till now, NASA has launched two missions to examine the cosmic radiation. The first mission was Cosmic Background Explorer (COBE). |
---|---|
Wilkinson Microware Anisotropy Probe (WMAP) |
It was an improved version of COBE. It surveyed the entire sky to measure the temperature differences of the microwave radiation. |
Planck |
It was a collaboration between the European Space Agency and NASA. It made the accurate maps of the microwave background radiation. |
Hubble Space Telescope (Not Mission) |
Hubble Space Telescope is a joint collaboration of NASA and ESA that continues the Edwin Hubble’s work to measure the expansion of the Universe. |
Origin of Universe : Big Bang theory & Current Cosmology
Origin of Universe: The story of how our universe began starts with a big event called the Big Bang theory. According to the Big Bang theory, everything began from a tiny and super hot point. From there, everything expanded fast by creating atoms. Most of the stuff in the universe is made of hydrogen, about 74% of it. This expansion has been happening for about 13.8 billion years, and now it seems like it is getting faster. However, some people disagree with the Big Bang theory.
They say it is based on the wrong idea that the universe is always expanding. They believe the universe is just staying the same which implies the early thoughts of Einstein. Later on, Einstein realized that the universe was getting bigger, but he had to change his theory to fit that idea. Our Solar System is a galaxy that is called the Milky Way. It has eight planets, including Earth, that go around the Sun. Besides the planets, there are also smaller things like asteroids, meteoroids, and comets flying around.
In this article, we are going to discuss the origin of the universe in detail. Let’s explore.
