What were chimps 1 billion years ago?
There were no chimps 1 billion years ago. At that time all life was single celled organisms and rudimentary multicellular ones.
What states that all matter and energy in the universe exploded ten to twenty billion years ago and began expanding in all directions.?
The theory that describes the origin of the universe as an explosion of all matter and energy is known as the Big Bang Theory. According to this theory, the universe began as a singularity and has been expanding ever since, roughly 13.8 billion years ago. This expansion continues today, leading to the vast and dynamic universe we observe.
About many years ago do scientists think the universe first started to form?
Scientists estimate that the universe began forming around 13.8 billion years ago during an event known as the Big Bang. This marks the beginning of the expansion of space and the creation of all matter and energy in the universe.
For about how many years do astronomers believe the solar system has existed?
Answer 1It has been around since God created it. Its not gazillions of years old. Dont believe that crud. It all a lie. The universe has no real creation date. Please read the bible, it will help open your eyes to so much knowledge. I'm not begging, just a suggestion to the reader.Answer 2The latest astronomical data shows the universe to be around 13.7 billion years old.
When was Neptune formed?
About 4.5 billion years ago, along with all the other planets.
When did earth become a planet?
Theoretically all the planets of the Solar system were created at the same time from dust caught in the suns gravitational field. That would have been around 5 billion years ago. the trapped dust coalesced into belts which further coalesced into asteroids and planets.
What were the continents called when they were all together?
When the continents were all together, they were called supercontinents. The Earth is thought to be 4.6 billion years old. The oldest theorized supercontinent is Vaalbara, which may have formed 3.3 billion to 3.6 billion years ago. The oldest known supercontinent is Ur, which formed 3 billion years ago. The Kenorland supercontinent formed 2.7 billion years ago. Columbia formed 1.8 billion to 1.5 billion years ago. Rodinia formed 1.1 billion to 750 million years ago. Pannotia, which also is called the Vendian supercontinent, formed 600 million to 540 million years ago. Pangaea formed 500 million to 200 million years ago. Laurasia formed 200 million years ago. And the last supercontinent was Gondwana. But that title may be held only temporarily by Gondwana. For the future may hold possibilities of one or two supercontinents within the next millions of years.
Did the Milky Way explode fourteen billion years ago?
No. The milky way did not exist at all, fourteen billion years ago. According to the Big Bang theory, the first galaxies started forming at least a million years after the universe had started to expand.
What is the first life?
Life on Earth began about 3.8 billion years ago, initially with single-celled prokaryotic cells, such as bacteria.
Did the Milky Way Galaxy explode fourteen billion years?
Stars that now exist within our Milky Way -- indeed, all stars themselves -- did not exist till about 13 billion years ago. Our galaxy did not take its present form till about nine billion years ago.
