How can the universe be infinitely old?

In cosmological terms, the scientists explain that the quantum corrections can be thought of as a cosmological constant term (without the need for dark energy) and a radiation term. These terms keep the universe at a finite size, and therefore give it an infinite age.

Does the universe have a finite age?

According to NASA, scientists know that the universe is flat with only about a 0.4 percent margin of error (as of 2013). “This suggests that the universe is infinite in extent; however, since the universe has a finite age, we can only observe a finite volume of the universe,” NASA says on their website.

How old can the universe get?

Planck. In 2015, the Planck Collaboration estimated the age of the universe to be 13.813±0.038 billion years, slightly higher but within the uncertainties of the earlier number derived from the WMAP data.

Is the universe finite or infinite?

First, it’s still possible the universe is finite. All we know for sure (mostly for sure) is that it’s bigger than we can observe, essentially because the farthest edges of the universe we can see don’t look like edges. The observable universe is still huge, but it has limits.

How big is the observable universe?

The observable universe is still huge, but it has limits. That’s because we know the universe isn’t infinitely old — we know the Big Bang occurred some 13.8 billion years ago. That means that light has had “only” 13.8 billion years to travel.

Is there more to the universe than we can see?

The universe is unquestionably huge. But is there even more that exists outside our observable bubble? First, it’s still possible the universe is finite. All we know for sure (mostly for sure) is that it’s bigger than we can observe, essentially because the farthest edges of the universe we can see don’t look like edges.

How long does it take light to travel through the universe?

That’s because we know the universe isn’t infinitely old — we know the Big Bang occurred some 13.8 billion years ago. That means that light has had “only” 13.8 billion years to travel.
