“The observable universe” - that is, the farthest thing in the universe that has been discovered
• The observable universe, or what is known as the observable universe, is a region in space in a spherical shape that represents the part of the universe that has been discovered for our time, which consists of the farthest objects that have been discovered for our time, or in a clearer sense, it is the region that includes the farthest regions that we have been able to discover in the universe by Telescopes, which include at least 2 trillion galaxies, and this is only the number of galaxies in the observable universe. It is possible that there are millions of trillions of galaxies that have not yet been discovered.
• The distance from planet Earth to the edge of the observable universe is estimated (about 46.6 billion light years). After studying the reason for our inability to monitor objects farther than the limit that we discovered (the observable universe) Because it is moving away from us at a speed exceeding the speed of light, and because of the cosmic expansion, which is the expansion of the universe, given that the universe is in a state of continuous movement and the galaxies continue to move away from each other, scientists expect that there will be “limited future vision” after it will be impossible for celestial bodies to enter our field of vision during the infinite future due to Because it is impossible for the light emanating from them to reach us, this means that the galaxies closest to us currently that we see in the future will gradually move away to the point of not being seen completely, even with telescopes.
And it will disappear completely from us due to the continuing expansion of the universe
After many studies, the assumption emerged that there may be universes larger than the one observed so far... and that it may contain billions and millions of objects and galaxies that we have not yet discovered. Which lies outside the scope of the region of the universe that we have been able to observe...
