How Can The Universe Be Infinite If It Started Expanding 13.8 Billion Years Ago

If the universe began expanding 13 points 8 billion years ago, how can it be infinite?If the universe is infinite, it has always been infinite; otherwise, how can it be infinite when it only began to expand 13 point 8 billion years ago? It was utterly dense at the time of the big bang. Since then, as space has grown, it has only gotten less dense. Any hypothetical collection of multiple universes is referred to as a multiverse or megaverse in cosmology and other fields.The cosmos is a second name for our universe. Greek is where the word’s origins lie. Early on, it was believed that our galaxy was the universe in its entirety.A tiny, infinitely dense ball of matter existed in the beginning. Then everything exploded, creating the atoms, molecules, stars, and galaxies we see today. Physicists have been telling us that for the past several decades, at least.

What evidence does science have that the universe is still expanding?

The universe’s finite age was first observed and supported by Edwin Hubble in 1929. He found that a galaxy’s apparent speed of space-regression increases with how far away it is from us, using the largest telescope available at the time. This indicates that the universe is expanding consistently in all directions. The more massive an object becomes as it moves more quickly, so why can’t you move more quickly than light? It requires more energy to accelerate an object as it accelerates, massening and becoming heavier. To accelerate an object to the speed of light would require an infinite supply of energy.Even though nothing can move faster than the speed of light, shadows are capable of outpacing it. This is a little difficult to comprehend. We’ll describe in more detail how that is feasible in a moment without defying physics’ most fundamental rule.The fastest thing is therefore light. That is the speed limit for everything. The universe’s speed cap could be compared to it.So, yes, you could say that the Universe is expanding faster than light over extremely vast distances. However, Einstein would not object. He only considers the movement of actual objects through space, from one location in the universe to another, as his cosmic speed limit.According to Einstein’s theory, traveling at or close to the speed of light would theoretically slow time, traveling at the speed of light would cause it to stop, and traveling faster than the speed of light would reverse time.

How is it that we can see light that is 13 billion years old?

Since light travels at the speed of light, if we observe an object that is 13 billion light years away, the light has been traveling in our direction for 13 billion years. In essence, we are viewing that object as it appeared 13 billion years ago. We measure the distance of most celestial objects in terms of light-years. The distance light travels in a year on Earth is measured in light-years. Approximately 6 trillion miles or 9 trillion km separate two light years. With 12 zeros after it, that is a 6!

How is the universe constantly growing?

Since the Big Bang, the universe has not expanded from a single location; rather, space has been elongating and dragging matter with it. Practically speaking, we are incapable of contemplating the end of space. The space between the multiverses is a void. In just a few seconds, the entire universe will have traveled billions of kilometers. Such universes exist in an infinitely large space that has no beginning or end.The multiverse is a vast ocean of possible universes, of which our universe is merely one. Physicists have described various types of multiverses, in case that idea isn’t difficult enough to comprehend. The cosmological multiverse is said to be the most understandable.

How do scientists know the age of the universe?

Although we are unsure of the universe’s exact age, we estimate that it is roughly 13 billion years old, give or take a few billion. Two methods are used by astronomers to determine the age of the universe: (a) by searching for the oldest stars; and (b) by measuring the universe’s rate of expansion and extrapolating back to the Big Bang. According to one study, the Methuselah Star predates the creation of the universe. With a 0 point 023 billion year margin of error, the universe is estimated to be 13 point 797 billion years old. The Methuselah Star was measured in 2013, and the results indicated that it may be 14 point 45 billion years old—older than the universe itself.To verify the universe’s oldest light’s age of 13+8 billion years, scientists looked at an image of it. A period of time 380,000 years after the universe’s creation, when protons and electrons first joined forces to form the first atoms, is marked by this light, the Big Bang’s afterglow known as the cosmic microwave background.Far from being 13. European Planck space telescope’s detailed measurements of cosmic radiation in 2013, the universe may be as young as 11. If that is, indeed, the case, then Methuselah is one again older than the universe.

How can the universe be 93 billion light years but only 13 billion years old?

The scientists have estimated their current location, due to the expansion of the universe as 46. This means that the farthest galaxies moved 30 billion light years away in 13. Located almost a billion light-years away, IC 1101 is the single largest galaxy that has ever been found in the observable universe. Just how large is it? At its largest point, this galaxy extends about 2 million light-years from its core, and it has a mass of about 100 trillion stars.The biggest single entity that scientists have identified in the universe is a supercluster of galaxies called the Hercules-Corona Borealis Great Wall. It’s so wide that light takes about 10 billion years to move across the entire structure.One such estimate says that there are between 100 and 200 billion galaxies in the observable universe. Other astronomers have tried to estimate the number of ‘missed’ galaxies in previous studies and come up with a total number of 2 trillion galaxies in the universe.
