In this episode, we’ll discuss the amazing discoveries of the James Webb Space Telescope. These discoveries have shattered the foundation of the Big Bang theory. They have discovered that the universe is much larger than it seems. The age of the universe is 13.7 billion years, but they have discovered a galaxy which is 33 billion light years away. How is this possible? This is a fascinating illusion being created by nature. Please continue listening to find out how and why this is happening.
Introduction
If you’re interested in science, you’ve probably heard about the James Webb Space Telescope, launched on December 25, 2021. James Webb Space Telescope represents a major leap forward compared to its predecessor, the Hubble Space Telescope, which has been orbiting Earth since 1990 at about 525 km altitude. Unlike Hubble, James Webb Space Telescope orbits the sun, positioned roughly one million kilometers from Earth with our planet always shielding it from direct sunlight. James Webb Space Telescope’s light-collecting ability outpaces Hubble by about six times, allowing it to capture clearer and more stunning images from the depths of space. While Hubble has delivered remarkable views of the cosmos, James Webb Space Telescope’s advanced technology and location in deep space mean its photos are even more awe-inspiring.
The primary mission of James Webb Space Telescope is to look further into the universe than ever before and investigate what happened around the time of the Big Bang. Scientists believe the Big Bang occurred about 13.7 billion years ago, marking the beginning of the universe. According to current theories, all energy and matter were compressed into a minuscule point known as Singularity, which then erupted with unimaginable force and heat. As the universe expanded, stars and galaxies began to form. Galaxies, immense systems containing hundreds of millions of stars, are thought to require more than a billion years to develop. The universe is estimated to contain around a billion galaxies, varying in size and age.
Building on this foundation, James Webb Space Telescope began its mission to explore deep space in June 2022. Hubble’s capabilities limited how far they could be observed, but James Webb Space Telescope’s powerful instruments have revolutionized our view. It captured images of the universe when it was only 200 million years old—meaning James Webb Space Telescope is probing light from 13.5 billion years ago. At that point, the universe was still in its infancy, with hydrogen atoms beginning to form in a vast gaseous state.
When scientists reviewed James Webb Space Telescope’s data, they anticipated seeing galaxies in their earliest stages. Instead, they were astonished to find mature, well-formed galaxies much sooner than expected. This discovery was surprising, as galaxies are thought to take billions of years to evolve. The presence of these advanced galaxies has challenged astronomers’ and cosmologists’ confidence in the Big Bang Theory, prompting some to reconsider fundamental assumptions about the universe’s formation. It has led researchers to believe they may need to rethink their approach and develop new models to explain these unexpected findings.
This episode proposes a fresh perspective for understanding the universe. It suggests that the expansion of space may be related to the stretching of the time fabric, which causes distant galaxies to appear farther away than they actually are. This optical illusion, created by nature, makes the universe seem larger than anticipated. To resolve this confusion, it’s crucial to examine these key topics:
- Starting Point of Space
- Expansion of Space
- Structure of Space
The Starting Point of Space
What exactly is the starting point of space? This question often leads to confusion. According to modern science, space began with the Big Bang roughly 13.7 billion years ago. In this view, the Big Bang marks the origin of both space and time. But does that mean the Big Bang is the starting point of space even now? The answer is a bit more complex.
While it’s technically accurate to say that space began with the Big Bang, that event occurred a staggering 13.7 billion years ago. So, where would we locate the starting point of space at this very moment? To pinpoint such a location, we would need to find a fixed, stationary point—something that never moves. However, the Big Bang itself isn’t such a point. Rather than being a stationary spot, the Big Bang represents the initial start of the universe, which, due to cosmic expansion, is always receding from us. In other words, the Big Bang location is not a motionless origin point, so it cannot serve as the current start of space.
Finding an unmoving reference point in space is difficult, because everything in the universe is in motion. The Earth rotates on its axis and orbits the sun, the sun and the solar system travel through the Milky Way, and even galaxies themselves drift apart. In reality, there is no absolutely fixed point in space.
Typically, we think about space in terms of physical distance—a tree might be 100 feet away, a house a mile distant, or a jet flying at 30,000 feet. This everyday approach doesn’t help us find a true starting point for space itself. Alternatively, we can shift our perspective and think about space in terms of time: specifically, the time it takes for light to reach us from various objects. This time-based viewpoint offers a fresh way to consider the structure of space.
The Observer as the Starting and Nonmoving Point of Space
Let’s consider the concept of a “nonmoving point” in space by thinking about time taken by light from different objects. The further away an object is, the more time its light takes to reach us—sunlight, for example, needs about eight minutes to get to us, while light from a nearby tree covers the distance in just ten microseconds. As the distance between observer and object decreases, the time required for light to travel also lessens. If we follow this reasoning to its logical end, light will only take zero time to reach us if the source and observer are at the same place—within our own mind. This can be thought of as the observer’s starting point in space.
Your mind acts as the starting point of space; it’s where space begins for you. The mind exists just outside the boundaries of space, and space starts precisely at the edge of your mind. Since the mind isn’t in space, it serves as the unmoving and original point from which space unfolds.
This “outside of space” is found within each of us, and it’s an awe-inspiring realization. We all carry something beyond space inside ourselves. This idea applies to every living being, everyone should understand that the unmoving origin of space resides within them. This starting point is constant and universal. No matter where you travel, your mind remains the reference point from which space starts. Wherever your body is, your mind is always the nonmoving start of space.
Expansion of Space
Is there a connection between time and space? Absolutely—time and space are fundamentally linked. Time acts as the driving force, while space emerges as its result. Without the passage of time, space would not exist; in essence, space can be viewed as stretched out time.
To better understand this relationship, consider what scientists say about the universe’s age: it is approximately 13.7 billion years old. If light were to travel from the farthest edge of the universe to us, it would take 13.7 billion years, meaning the distance is 13.7 billion light-years. A light-year is simply the distance light covers in a year.
Let’s explore how the universe’s age and size relate. If the universe is 13.7 billion years old right now, its size is 13.7 billion light-years. After one second passes, the age becomes 13.7 billion years plus one second. In that extra second, light travels an additional 186,000 miles. So, the universe’s size increases by 186,000 miles, making it 13.7 billion light-years plus 186,000 miles. Ten seconds later, the universe’s age is 13.7 billion years plus ten seconds, and its size grows by 1,860,000 miles. After a year, it’s 13.7 billion years plus one year, and the universe expands by another light-year.
This demonstrates that time directly causes the expansion of space. As time flows, space continues to expand. Each second, the universe expands outward by 186,000 miles. In other words, the edge of the universe is growing by 186,000 miles every second, which is a remarkable insight.
Understanding Time Fabric
To begin, it’s helpful to clarify some of the main terms used when talking about space. Einstein introduced the concept of a “fabric” underlying space and called it spacetime fabric. The term spacetime can be confusing since it seems to refer to both space and time together, but the distinction is important. Space is what we observe directly—it’s the three-dimensional arena where distances are measured. For example, you might see a tree 200 feet away or a plane flying at 30,000 feet. All these measurements are made using distance units, and this domain is what we typically think of as space.
Spacetime, on the other hand, describes phenomena in terms of time rather than physical distances. The term itself can be misleading, as it suggests a blend of space and time, but in this context, it is primarily time that is being considered. For instance, when we say light from the sun takes eight minutes to reach us, or that a star is 500 million light-years away, we are measuring in units of time. Thus, everything in spacetime is quantified by time alone. Using the term “time fabric” can be more precise, emphasizing that time is the true variable at play in spacetime. As discussed in the episode “Understanding Time,” time is not something that exists in the three dimensions of space but is the fourth dimension. The fourth dimension can exist only in the mind. Therefore, it’s more accurate to think of the spacetime fabric as a time fabric that exists within our mind.
But how does space come into existence? Space is formed by the stretching of this time fabric. For a more in-depth discussion, refer to the episode “Dark Energy and Space.” Dark energy has the unique ability to stretch time, and this stretching is what creates space. To put it simply, when one second of the time fabric is stretched by dark energy, it becomes 186,000 miles of space. This means that all the space we perceive around us is actually the result of time fabric being stretched out to form space. While this concept may seem unfamiliar, it is both logical and consistent.
With a clearer grasp of the time fabric and how space originates, we can derive a few key insights about the structure of space:
- The starting point for both the time fabric and space is the observer within us. This observer serves as the fixed, unmoving reference point for all space.
- The outermost edge of the universe’s time fabric lies 13.7 billion years away, and it continues to expand at a rate of 186,000 miles per second, or the equivalent of one light-year every year.
Revised Framework of Space:
Consider space as having a fixed starting point that never shifts. However, its outer boundary is constantly expanding—by one light-year each year. To visualize what happens between the fixed beginning and the ever-expanding edge, think of a rubber band anchored at one end while the other end is pulled outward. You’ll notice that as you stretch the band, areas closer to the anchor point expand less, while those near the moving end stretch much more. The farther you move from the fixed point, the greater the expansion in the rubber band.
This analogy applies to the fabric of time as well. The beginning of the time fabric is fixed, while its outer edge is continuously expanding. As time progresses, the fabric gets stretched more and more at its edges. Because the starting point remains unchanged and the edge moves outward, the entire time fabric is pulled and expanded. This stretching isn’t uniform—near the starting point, time is less stretched, but at the extremities, it’s stretched much more. In practical terms, this means that a “second” is not the same everywhere along the time fabric: it’s shorter near the beginning and becomes increasingly stretched as you move toward the outer edge.
How does this stretch of time influence space? Each second of stretched time translates into 186,000 miles of space. When a second is more stretched, it creates proportionally more space—so, the 186,000 miles become an even greater distance. Therefore, as the stretching increases, the universe appears larger than it would if time weren’t being stretched. This effect is most noticeable at the universe’s outer edges, making these regions look much larger from the observer’s viewpoint, and giving the impression the size of the universe is much larger than what it actually is.
Nature’s Optical Illusion
Nature has created a fascinating illusion, making space seem far more expansive than it really is. This effect is currently challenging scientists who use the James Webb Space Telescope to study distant galaxies. Despite the universe being about 13.7 billion years old, researchers have found a galaxy that appears to be 33 billion light years away, even though logically it should only be around 13.7 billion light years distant. As previously discussed, this inconsistency stems from the stretching of time across the fabric of the universe, causing it to appear larger. To address this, scientists will need to update their calculation methods to account for this stretching effect. By making these adjustments, they should be able to accurately measure the distances of both nearby and faraway galaxies, leading to a clearer understanding of the universe.
I hope you found the exploration of the space framework both fascinating and enlightening. It’s essential for the scientific community to recognize that the starting point of space is the observer within each one of us. Furthermore, the universe’s outer boundaries are stretching the fabric of time, which creates an illusion that makes the universe appear much larger than it truly is. Understanding this concept is crucial for clarifying the misconceptions caused by images from the James Webb Space Telescope.
