How do scientists explain the origin of the universe?
Scientists theorize that the universe began with the Big Bang around 13.8 billion years ago, when all matter and energy were concentrated into an extremely hot and dense point. This point rapidly expanded, leading to the formation of stars, galaxies, and everything we see today.
The big bang theory states that the galaxies in the universe are?
The big bang theory states that the galaxies in the universe are continuously moving away from each other due to the expansion of space. This expansion suggests that the universe began from a hot, dense state approximately 13.8 billion years ago.
What states that are between 15 and 20 billion years ago the universe began expanding out of an enormous explosion?
The Big Bang theory states that approximately 13.8 billion years ago, the universe began expanding out of a dense and hot state, rather than 15-20 billion years ago. This theory is supported by observations such as the cosmic microwave background radiation and the redshift of distant galaxies.
How long has space existed?
Space has existed for approximately 13.8 billion years, which is the age of the universe according to current scientific estimates. This is based on the Big Bang theory, which suggests that the universe began as extremely hot and dense, expanding and cooling over time to form the vast expanse of space we see today.
How was the universe created according to modern science?
According to modern science, the universe was created in a burst of energy 13.7 billion years ago that expanded space, began time, and eventually evolved into matter which then eventually became life and intelligence. So it was energy that created the universe since it can never be created or destroyed. We commonly know this as the Big Bang.
When was hydrogen made?
When the universe was dense enough and hot enough for fusion during the Big Bang some 13 billion years ago.
When and how did the universe begin?
The Universe is generally believed to have started very small, very hot, and very dense; from there, it expanded to its current size (and it continues expanding). This hot and dense beginning, generally known as the Big Bang, was about 13.8 billion years ago.
What do you call the theory that the universe began as a very hot and dense concentration of matter?
The theory is called the Big Bang theory. It suggests that the universe began expanding from a very hot, dense state approximately 13.8 billion years ago.
How do scientists explain the origin of the universe?
Scientists theorize that the universe began with the Big Bang around 13.8 billion years ago, when all matter and energy were concentrated into an extremely hot and dense point. This point rapidly expanded, leading to the formation of stars, galaxies, and everything we see today.
How is the origin of universe explained?
There is a lot of evidence that some 13.8 billion years ago, the Universe was in an extremely dense and hot state, commonly called the "Big Bang", and that since then, it has been expanding.It is not currently known what happened before that.
What does the term big bang mean?
big bang refers to the way scienctists think the world is created.they think there was a big bang and the universe was formed. there are also different religions that disagree with this and some other scienctist do have different views of this as some think the universe is getting smaller.
The big bang theory states that the galaxies in the universe are?
The big bang theory states that the galaxies in the universe are continuously moving away from each other due to the expansion of space. This expansion suggests that the universe began from a hot, dense state approximately 13.8 billion years ago.
What actually formed the universe?
actually it all started at a explosion called the big bang first the universe was stuck inside the explosion untill the universe began to expand inside this explosion pushing and making this explosion expand, finally when the explosion exploded the universe was formed
The big bang refers to?
The Big Bang refers to the rapid expansion of the universe that occurred approximately 13.8 billion years ago. This event marked the beginning of the universe's evolution from a hot, dense state to the vast and complex cosmos we see today.

Where did the cosmic microwave background (CMB) come from and what does it reveal about the early universe?
The cosmic microwave background (CMB) originated from the hot, dense state of the early universe about 13.8 billion years ago. It is the afterglow of the Big Bang and provides crucial information about the early universe, such as its temperature, composition, and density fluctuations. This radiation helps scientists understand the evolution and structure of the universe.
When and how was universe formed?
The universe was created roughly 13.7 billion years ago. The most widely accepted scenario for the creation of the universe is known as the big bang theory. In lay man's terms, the theory says that the universe was created through a rapid expansion of time and space that still continues today as the universe expands.
