Billions of years ago galaxies existed in?
Galaxies. They are just about the same now as they were then. 14 Billion years ago, astronomers believe that the "Big Bang" created matter from energy, which is how they believe galaxies were formed.
What is the name of the supercontinent that existed over 5 billion years ago?
There was no supercontinent back then. Earth is about 4.6 billion years old. It did not exist 5 billion years ago.
Billions of years ago galaxies existed as what?
Hot clouds of dust and reactive gases
Did dinosaurs live two billion years ago?
No, vertebra life has not existed for more than half a billion to a billion years ago. Dinosaurs first appeared about 230 million years ago and died out 65.5 million years ago.
How long ago do scientists estimate this supercontinent existed?
3 billion years.
What supercontinent existed approximately 1.1 billion years ago?
The supercontinent that existed approximately 1.1 billion years ago was Rodinia. It was a precursor to Pangaea and consisted of most of Earth's landmasses at that time. Rodinia began to break apart around 750 million years ago.
How long has organism been in the US?
If there is life, there is organism. It existed billion of years ago.
How long ago did the galazies form?
Galaxies began forming around 13.6 billion years ago, not long after the Big Bang that created the universe. Over time, gravity caused matter to clump together, eventually forming the galaxies we observe today.
When did Rodinia form?
Rodinia formed about 1.3 billion years ago.
When did the first galaxies and stars develop?
About 13-14 billion years ago. Cosmologists are not in agreement as to what happened the first few million or billion years, but most agree that the age of our Universe is about 15 billion years.
Which continent was the first continent?
Ur is the first known continent and existed 3 billion years ago.
How do you know that the universe is 13 billion years old?
This is mainly an extrapolation of the expansion of the Universe. That is to say, the Universe is expanding at such a rate that the galaxies (or the matter that didn't convert to galaxies yet) would have been very close together 13 or 14 billion years ago.
