They estimate the age of the Universe in more than 12 billion years.
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.
Yes
The big bang or a wormhole
14 billion
Flat model
no because scientists think that earth is the only planet in the universe that supports life :3
scientists think that they do. there is one in every galaxy. also in ours
Many scientists consider the possibility life exists elsewhere in our universe (and more particularly even within our own galaxy) quite likely. A few do not think it is likely.
Scientists who study the universe are known as cosmologists.
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
They (scientists) think there are hundreds of thousands of galaxies because the universe is limitless so there may be billions of galaxies!
4.6 billion years
