What else can I help you with?
How old do Scientists think that your universe is?
Scientists estimate that the universe is approximately 13.8 billion years old based on observations of the cosmic microwave background radiation and the expansion rate of the universe. This age is derived from various cosmological models and theories, such as the Big Bang theory.
How old is the star capella?
Capella is estimated to be around 500 million to 700 million years old, which is relatively young compared to other stars in the universe.
What do astronomers mean when they use the term observable universe?
That portion of the universe from which light from distant objects can reach us which has been traveling since it was possible for light to travel through the universe (about 380,000 years after the Big Bang) This is a sphere centered on Earth extending 46.6 billion light years in all directions. That sphere gets slightly bigger every day. Note also that even though the universe is 13.798 billion years old the observable universe is larger becuase the universe has been expanding during that 13.798 billion years.
What do scientist tell us about the age of the universe and the age of the planet?
The universe is 13.7 billion years old & Earth is 4.5 billion years old.
How long will the universe live?
The universe is estimated to be around 13.8 billion years old and is expected to keep expanding indefinitely. Current theories suggest that the universe will continue to exist for billions of years, but its ultimate fate is uncertain.
How old do scientists think the universe?
They estimate the age of the Universe in more than 12 billion years.
When do you think the universe was formed?
It is currently believed that the Universe started something like 14 billion years ago, with the Big Bang.
Since the universe is thought to be expanding why do galaxies collide?
Because although the universe is expanding, the galaxies within it are grouped into clusters. These clusters are still under the influence of gravity, so slowly, over many years, they are attracted towards each other and can collide with one another.
Did scientific think the earth was the center of the universe?
Yes, for close to 1,400 years everyone believed the Earth was the center of the universe. It was not till 1543 that a man named Copernicus created a model with the sun as the center of the universe. The Catholic Church clung to the idea of the Earth as the center of the universe for over 90 years.
Who believes that there are more creatures in the universe cause I do?
Yep I do too!!!! Without a doubt there are. It would be pretty arrogant of humans to believe that in the whole universe Earth is the only planet with life on it. Scientists already think that there are bacteria on mars. So that's at least one other planet with life on it. We will find intelligent life out there somewhere. Just a matter of time (it's only within the last 60 years that we've had the ability to find it) not very long considering the size of the universe.
How did the universe look like a googol years ago?
There was no universe a googol years ago. The universe is only about 14.5 billion years old.
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.
How big is the universe 9898754364575272657277777777777777777777777777777777777777777777772222222222222222222222222222222222222222222222222222222222 years ago?
That was before the whole expansion started, so 0 miles or any other measurement in volume. The Universe is only about 13 billion years old.
What is the universe's age?
Right now scientists think the universe is about 14 billion years old; that's the short answer. For a longer discussion, read here: http://en.wikipedia.org/wiki/Age_of_the_universe Of about between 15000 and 20000 million years
How many times older is the Universe than the earth?
Only a little than 4x older actually, the universe is roughly 16 billion years old and Earth is approximately 4.5 billion years old. Of course there are other estimates that the universe is as young as 12 billion years and as old as 20 billion years
Is the universe about 14 million light-years old?
A light year is a measure of distance, not of time. The universe is, according to our current hypotheses, about 15 billion years old. However, please note that every time throughout history that "science" has declared the age of the Earth, of the Sun, or of the Universe, they have invariably been wrong. Things always turn out to be vastly older than we used to think. We used to think that the Earth was a few thousand years old, then a few million years old, and now we think the Earth is about 4.5 billion years old. Have we finally gotten it right? Ask me in 100 years.
What is the longest known distance in light years?
That would be the distance from one edge of the Known Universe to the other. As the Known Universe is believed to be approximately 15 billion years old, that would be 30 billion light years in diameter.
