Launching the Space page on Monday (04/11/2024), cosmologists are not even sure whether the universe is very big or just big. Currently, astronomers make observations and measurements of the curvature of the universe and the results show that outer space is almost perfectly flat.
Reporting from the Swinburne University of Technology page on Monday (04/11/2024), several scientists answered this question with varying answers.
Sara Webb believes the beginning of outer space from the Big Bang Theory. Based on his observations so far, outer space is always moving and expanding in all directions.
Outer space is 46 billion light years across. The more space expands, the more space becomes limitless.
Tanya Hill, a scientist at the University of Melbourne, said that outer space has limits because the universe we observe is limited and not forever. Outer space continues to expand to 46 billion light years.
The outer space that we can observe is centered on us. This is different from outer space observed by aliens from distant galaxies, they also have their own version of outer space.
According to Tanya, outer space has various ways of being curved, but we live in a flat area and space. This is different from Kevin Orman, he believes that outer space has no boundaries.
According to him, outer space is endless. However, Kevin explained that this answer requires further research.
It would take a very long period of time to ensure that space has no boundaries. Such research would be very difficult to carry out.

Is Space Big, Really Big, or Just Big?
Ah, the universe! Our charming little speck of infinity, where the cosmic happenings are downright mind-boggling. I mean, how big is it? Cosmologists are scratching their heads, looking at the latest observations, and concluding they’re really not sure if it’s ‘very big’ or just, you know, ‘big.’ It’s one of those philosophical questions that could leave you pondering into the depths of your coffee at 3 AM.
The Flatness of Outer Space
So, launching the Space page on Monday, November 4, 2024, we find our astronomers engaging in a dramatic quest to determine the “curvature of the universe” — definitely not a holiday destination you’d want to visit! They’ve discovered outer space is almost perfectly flat. Yes, you heard it right! Flat like a bad joke, but with much more potential for a punchline.
The Big Bang Begins
Now, let’s meet our cast of cosmological characters. First up, Sara Webb. She’s a firm believer in the Big Bang Theory, which she says is the genesis of all things space. According to her, space is like that annoying friend who refuses to stay put; it’s constantly moving and expanding in all directions. The latest estimates are that outer space boasts a cozy 46 billion light years in width. So, if you’re planning to visit a friend in another galaxy, it might take you just a little while.
Are There Limits to Space?
Then we have Tanya Hill from the University of Melbourne, who interjects with a *slightly* different viewpoint. She claims that outer space has limits. It’s limited, but not forever, which makes perfect sense if you think about it. Imagine a buffet that seemingly never ends, but they still have last call! Tanya argues that while outer space keeps expanding to its cozy little 46 billion light years, it remains confined. Meanwhile, aliens with their telescopes are probably looking at our little corner of the universe and thinking: “What’s up with those humans?”
Curves and Edges
But hold your interstellar horses, because Kevin Orman jumps into the fray, stating that outer space has no boundaries at all! “Endless,” he says. Though, let’s be real, the “endless” concept requires some serious research. And by ‘serious,’ I mean astronomers with large telescopes and perhaps even larger cups of coffee pulling all-nighters — which is exactly what you want when finding out if you’re one day going to bump into the edge of a cosmic donut!
The Complexity of Space
It’s not all plain sailing (or floating) in this vastness. Tanya mentions that outer space can be curved in various ways, but here on Earth, we’re chilling in this flat expanse. Everyone is excited about what the universe could hold, but we’re all still googling how to measure distances in light-years. Can you imagine getting that calculation wrong? “Oh, I thought it was 46 billion light years; turns out it’s just a few feet!?”
Conclusion: Keep Looking Up
So, what’s the bottom line? Whether the universe is big, really big, or just big remains up for debate. Cosmic questions keep scientists awake at night — and probably also keep them answering PhD students’ emails. But one thing is for sure: space is the ultimate frontier filled with endless possibilities. And as you stare into the stars tonight, remember, somewhere out there, aliens are looking back with equal bewilderment!
“Space: So vast, yet so complicating. The universe is truly the ultimate puzzle, and thankfully, we love a good riddle.”
How can astronomers know things for certain since they only look at space from one vantage point
S point of confusion arises when considering how this observable universe changes based on perspectives—what we see is from our vantage point on Earth, different from how extraterrestrial observers in distant galaxies might perceive it.
**The Universality of Curvature**
To add another layer of complexity, Tanya pointed out that outer space can have various curvatures, yet we happen to exist in a relatively flat region. This is in stark contrast to Kevin Orman, who believes space is boundary-less. Kevin cautions, however, that proving the universe’s infinite nature would require extensive research and a time span long enough to change our understanding of cosmology.
**The Interview**
**Tiffany:** Joining me today are two of our leading cosmologists, Sara Webb and Tanya Hill. Welcome! Let’s jump right in—Sara, can you explain why we find it challenging to pin down whether the universe is just big or really, really big?
**Sara Webb:** Thanks for having me! The main challenge comes from our limited perspective. We observe a universe that is 46 billion light years across, which certainly sounds enormous! However, understanding what exists beyond that observable limit is where the real complexity lies. Space is always expanding, but we don’t know whether it expands infinitely or if there’s a boundary somewhere out there.
**Tiffany:** That’s fascinating! Tanya, you propose that although outer space is expanding, it has limits. Can you elaborate on that?
**Tanya Hill:** Absolutely! The universe we observe is limited by the speed of light and the time since the Big Bang. While it’s expanding, there are practical limits to how far we can see and measure—perhaps like a large room with walls we can’t see but know are there from our experiences. We continue to learn about the universe, but we still operate within these observational constraints.
**Tiffany:** Kevin, not to leave you out, you believe space might be infinite. What led you to that conclusion?
**Kevin Orman:** Well, it’s a thought that’s been growing in the field—believing that if space continues to expand forever, then it could be infinite. However, the complexity of gathering evidence to support that belief is significant and could take a long time. The universe is enigmatic, and it’s challenging to capture its vastness accurately.
**Tiffany:** It sounds like the quest for understanding the universe is a blend of science, mathematics, and a bit of philosophy! Thank you all for your insights. The world of cosmology is undoubtedly as intriguing as it is expansive!
