How old is the universe?

The estimated age of the universe is 13 billion years old. One way they have figured this out is finding the temperature of a white dwarf, which is a type of star. ChaCha!

Scientists believe the Universe is at least 15 billion years old, but probably not more than 20 billion years old. The Solar System is thought to be 4.5 billion years old and humans have existed as a genus for only a few million years. ChaCha!

Scientists think the age of the universe is currently 13.7 +/- 0.2 gigayears. A gigayear is one billion years. This age is based on the age of the chemical elements, the age of the oldest star clusters, and the age of the oldest white dwarf stars.

The universe is roughly 13.73 billion years old, based on precision measurements of the oldest light in the universe. ChaCha.

Current theory and observations suggest that the universe is between 13.5 and 14 billion years old. That's old!

The Universe itself is believed to be over 6 Trillion years old. Though this is only a theory that pertains to the big bang. Thanks!
