What would the approximate age of the universe be in that case?

According to research, the universe is approximately 13.8 billion years old.

What is the evolution of the universe over the last 13.7 billion years?

The broadly accepted theory for the origin and evolution of our universe is the Big Bang model, which states that the universe began as an incredibly hot, dense point roughly 13.7 billion years ago.

How did scientists determine the approximate age of the universe?

Astronomers estimate the age of the universe in two ways: 1) by looking for the oldest stars; and 2) by measuring the rate of expansion of the universe and extrapolating back to the Big Bang; just as crime detectives can trace the origin of a bullet from the holes in a wall.

What is the approximate age and size of the universe?

The universe is (nearly) 14 billion years old, astronomers confirm. With looming discrepancies about the true age of the universe, scientists have taken a fresh look at the observable (expanding) universe and have estimated that it is 13.77 billion years old (plus or minus 40 million years).

Is the universe 13.9 billion years old?

With this data, cosmologists calculated the universe’s age to be 13.5 to 13.9 billion years old. About a decade later, the Planck satellite measured the CMB in even more detail, getting a Hubble constant of 67.66 and an age of 13.8 billion years. “It speaks to the fact that these difficult measurements are reliable.”

Can we see 13.8 billion years ago?

Stuff is everywhere, and light travels at the speed of light. This is the “default” mode most people have. So after 13.8 billion years, you’d expect to be able to see back almost 13.8 billion light years, subtracting only how long it took stars and galaxies to form after the Big Bang.

Is the universe 14.5 billion years old?

The universe is (nearly) 14 billion years old, astronomers confirm.
