Missions to Study Big Bang

Current Cosmology

Will the Universe Expand Forever?

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.

Origin of Universe

On the basis of Big Bang theory, scientists explain how the universe started. They think everything in the universe used to be soft as a tiny hot ball. About 13.8 billion years ago, everything began from a tiny, super hot, and packed point called a singularity. From there, the universe spread out and cooled down, forming galaxies, stars, and planets. Many scientists think this is how the universe began. When neutral atoms formed, they released light particles called photons. We can still see these photons today as the cosmic microwave background (CMB)....

Origin of the Universe Theories

Long ago, people began to study the Universe. During Greek civilization, people developed two new ideas about universe including the geocentric view and the holocentric view....

How Old is the Universe?

Scientists say the universe is old around 13.8 billion years old. They believe it all started with a big explosion called the Big Bang around the same time. Since then, everything has been spreading out. To figure out how old it is, scientists study stuff like the leftover radiation from the Big Bang and how light from faraway galaxies changes....

Big Bang Theory

The Big Bang was a expansion of space and time. About 13.8 billion years ago, everything began from a tiny, super hot, and packed point called a singularity. From there, the universe spread out and cooled down, forming galaxies, stars, and planets. It is still expanding today, and scientists wonder if it might shrink back someday. So, the Big Bang is not really a bang like we think of explosions. It is more like the start of everything....

Will the Universe Expand Forever?

The universe’s future depends on a fight between things pushing it apart and things pulling it together. Imagine the universe is like a balloon being blown up or deflated. How fast it expands is measured by something called the Hubble Constant, and how much it wants to collapse is due to how much stuff is inside pulling on it. If there is not much pressure pushing out from the stuff inside, then what really matters is how much stuff there is. If there is not a lot of stuff, the universe will keep on expanding forever. But if there is a lot of stuff, it will eventually pull the universe back in on itself, like a collapsing bubble, called the “Big Crunch”....

Conclusion on Origin of Universe

The origin of the universe remains one of the mysteries of science. Despite centuries of research, our understanding is continually evolving, shaped so many new discoveries and profound theoretical frameworks. From the Big Bang theory’s elegant explanation of cosmic expansion to the possibilities hinted at by quantum mechanics and string theory. Scientists are on an ever-unfolding journey to unravel the cosmic tapestry. While we may never fully grasp the ultimate origins of our universe, the pursuit of knowledge continues....
