New Study Reveals That Our Universe Is 27 Billion Years Old, Not 13.8 Billion! Here’s How

**How old is our universe?** This is one of the most fundamental questions in cosmology, and we thought we had the answer: about 13.8 billion years. But what if we are wrong? What if our universe is twice as old as we thought, and that changes everything we know about its history and evolution?

In this video, we will explore a shocking new discovery that suggests that our universe is 27 billion years old, and what it means for our understanding of the cosmos. We will also look at some of the mysteries and puzzles that led scientists to question the age of the universe in the first place, and how they used a new model to solve them.

We will talk about how the James Webb Space Telescope has discovered early galaxies that seem to be far too advanced for their age, and how this challenges our theories about the origin and evolution of galaxies. We will also discuss how this new study can affect some of the fundamental questions and mysteries that we have about the universe, such as what happened before the Big Bang, what is the shape and size of the universe, and what is the destiny and fate of the universe.

This video is based on a new study by Rajendra Gupta, a physicist from the University of Ottawa, who claims that our universe is not 13.8 billion years old, but 27 billion years old. His study is published in Physical Review D in November 2021.

I'm a retired family doc. Years ago, an internist said something that has always stuck with me. "One study in medicine seldom proves or disproves anything." I strongly suspect that the same thing applies in cosmology. It will take a lot more observation and explanation before it can be reasonable to accept that the universe is actually twice as old as thought today. And that's a good thing. it means that there's a lot of work to do. Science doesn't deal in certainties. If you thought it did, then to quote Richard Feynman, "That's just an error on your part".

[tonymaiorano]

I like the fact that real scientists admit that the more they learn, the more they need to learn .

[thereisnospoon]

No wonder I'm always tired, I'm 14 billion years older than I thought I was.

In 1965 I was in third grade when they told us about this neat new concept for a theory called "Continental Drift". Science helps us learn new things all the time if we pay attention.

A single new paper proposing a ton of new physics proposes this in response to the high redshift objects found in JWST's early images. The original paper that identified those objects pointed out that it used a model which assumed that stars, star formation, and galaxies were essentially the same at the beginning of the universe as they are today. Once the high redshift objects were reexamined more carefully using better spectroscopic equipment, they have all been found to be much lower redshift objects that happen to be particularly red. To be clear about what I mean: The original observations noted these objects based on their overall spectrum without looking at specific points in the spectrum - they were super red. When observations of the same objects were made more carefully such that their spectra were able to recorded in greater detail, it was found that the actual cosmological redshift was much, much less (they looked at the Lyman break, specifically, if anyone cares).

9:37 "But whether Gupta's study is right or wrong..." 9:57 "It shows us how old our universe really is..."
I'm pretty sure it only shows us how old our universe really is if it's right. XD

Also love how there's a whole section called "The Implications" (7:04) and it starts with "If Gupta's study is correct ..." And then they ask questions that we'll have to rethink. And yet Gupta's study, if correct, has no further implications for the first and second questions asked beyond what we already know! The guy literally asks the only questions about cosmology that Gupta's study doesn't have any implications for. XD

20 years later: our universe is actually 50 billion years old.

[dabiguy]

Anyone suffering from stress ir anxiety. Take up watching cosmology videos. Its soothing to realise just how big the universe is, how long its been around for, and how long it will continue after we are gone. I wish you all well.

This is how science works. Building new tools. Obtaining more data. Revising and refining our models. Humans are quite amazing.

[RichSDet]

Been 40 years since I had physics in college. Everything has changed. Now that’s progress!😅

[Dbro]

Shouldn’t say ‘how old the universe really is’. Should say ‘this is how old we now think it is’. We need stop making the assumption we have all the answers just because we learned something new. There likely even more we don’t know that will change our answer in the future.

[williamwhitney]

I've always been confused when they say a galaxy is a certain distance away, say 10 billion light years. It seems they're saying it WAS 10 billion light years away, 10 billion years ago because that's how long it took its light to reach us. So, to me it seems, it's actually double the age we're seeing it as. Aspirin, please.

[commanderthorkilj.amundsen]

No matter how sophisticated the instrumentation, computer modeling, and mathematical calculations appear to be, any discussion of the age and size of the universe relies on extrapolations and assumptions from our infinitesimal scope of vision over a tiny bit of time.
Cosmologists live in the realm of tautology and circular reasoning, backed up by mathematical equations based upon unprovable assumptions, but few will admit it.

[tdpay]

This is a fascinating story. Gupta's paper might have languished in relative obscurity were it not for recent discoveries of objects older than 13.7 billion years courtesy of the James Webb telescope. As a result, 20 months after the paper was published, the older universe idea has entered the mainstream media and the public consciousness. Also, Gupta revived two theories from the early years of the previous century and put them together in a creative way. This shows the value of knowing and drawing upon the intellectual history of one's own discipline.

[johnthomas]

Thats the beauty of science. We get new data. Revise our theories based on the data if necessary and keep moving forward.

[tylero]

I think its safe to say we will never know the real age of the universe. It has probably been here forever and will never end. That wrecks my mind.

[jroar]

If the Universe is accelerating, one would agree that the closer you get to the beginning of the big bang, acceleration would be slower to the point of a complete stop.

finally, a channel that actually discusses the actual posted title of their video, no click bait. well done NASASpaceNews you have earned yourself a new subscriber.

[donaldkasper]

"Universe" means "everything", so then there aren't multiverses. All of space cannot have multiple spaces, it has just one.

[MasterSpade]

So we are finding out that the Universe is twice as old as the 13+ Billion Years we thought. Yet there are still people that believe this world is 6K years old...
