They concluded that the Universe is at least 250 times larger than the observable universe, or 7 trillion light-years across. But, ultimately, science has no reliable estimate of the actual size of the entire Universe.94 Billion Light Years
Size: 94 Billion Light Years. The most distant objects in the Universe are 47 billion light years away, making the size of the observable Universe 94 billion light years across. How can the observable universe be larger than the time it takes light to travel over the age of the UniverseThe light-travel distance to the edge of the observable universe is the age of the universe times the speed of light, 13.8 billion light years. This is the distance that a photon emitted shortly after the Big Bang, such as one from the cosmic microwave background, has traveled to reach observers on Earth.
Is the universe 1 trillion years old : An image of many stars. The observable universe is currently 1.38×1010 (13.8 billion) years old. This time lies within the Stelliferous Era.
Is space infinite
Cosmologists aren't sure if the universe is infinitely big or just extremely large. To measure the universe, astronomers instead look at its curvature. The geometric curve on large scales of the universe tells us about its overall shape. If the universe is perfectly geometrically flat, then it can be infinite.
Is the universe infinite : The observable universe is certainly finite, and indeed we know approximately how large it is. It's very large—literally incomprehensibly so to human intuition, in fact—but still finite. Current cosmological evidence suggest the entire universe is isotropic, spatially flat, and infinite.
In July 2023, a study published in the Monthly Notices of the Royal Astronomical Society journal put the age of the Universe as 26.7 billion years. If the findings of this latest research prove accurate, the Big Bang may have taken place 26.7 billion years ago, making the actual age of the universe nearly twice as old as we thought.
What existed 1 trillion years ago
At the cosmic origin, a trillion years ago, all that existed was an endless Light Ocean. Inexhaustible was this frozen supply of light available for black holes to continually build spheres and solar systems in galaxies.In either case, you could never get to the end of the universe or space. Scientists now consider it unlikely the universe has an end – a region where the galaxies stop or where there would be a barrier of some kind marking the end of space.By all accounts, the universe appears to have no boundary. It has no end. On the other hand, the universe is only as big as the area expanding to fill it all up. And it's been doing that since the big bang. Recent research suggests it may be infinite, implying that there could be an infinite number of galaxies. However, there is a limit beyond which we cannot see; because light from beyond has not had time to reach Earth since the Big Bang.
Can we see 14 billion light years away : Its observable limit, for us, is the distance 46.5 billion light years in any direction. But forget “limit.” We cannot see anything from anywhere near this distance. Beyond 14.5 billion light years away (the Hubble distance), light in this expanding universe moves only away from us, not towards us.
Is there a galaxy 32 billion light years away : GN-z11 displays a high redshift (of the order z = 10.95). This implies that it is located approximately 32 billion light years away from the Earth.
What existed 14 billion years ago
We can trace the history of our universe back about 14 billion years, to a fiery period known as the Big Bang. At that time, the universe was extremely hot and dense. In fact, all the matter we observe today – out to the furthest galaxies we can see – was packed into a space smaller than a grapefruit. After 1 sextillion years, the Earth will hit the Sun if it can still survive in the Solar System. The reason for this is the deterioration of Earth's orbit due to gravitational radiation.French researchers have discovered that life was already moving on our planet earlier than first thought — now thought to be 2.1 billion years ago. Previously, early life forms were said to date back 1.5 billion years.
Is the space really infinite : Is outer space "finite" or "infinite" We really don't know. The nature of the expansion of space (which expands more rapidly the further things are from us) means that at 45 billion light years away is the limit of what we can see – or can ever see. We know that what we can see is finite – but that's no surprise.
