Is it possible for the universe to be infinite?
The observable universe is finite in that it hasn’t existed forever. It extends 46 billion light years in every direction from us. (While our universe is 13.8 billion years old, the observable universe reaches further since the universe is expanding).
Are there infinite universes with infinite possibilities?
There are infinite possibilities of existence of multiple universes which means that everything that can happen may happen in one or the another universe.
Is the universe an infinite loop?
An infinite loop: New research suggests the universe may be a closed sphere. Most people think of space as a flat sheet: You travel in one direction, and you end up far from your starting point. And a closed universe would be a sphere, with a beam of light eventually looping back around it to meet its origin.
Are there infinite galaxies?
Our universe is just a finite number of galaxies rushing away from each other inside this empty infinite space—like a solitary skyrocket exploding and sending out a doomed shower of sparks.” But many cosmologists say, no, there are an infinite number of galaxies in our infinite space.
How much of the universe can we see?
The universe may be infinite, but we can only see a finite section of it due to the finite speed of light. We can only see those parts from which light has had time to reach us since the beginning of the universe – which means we can (in theory) see a spherical universe with radius of about 47 billion light years.
Is the universe infinite or finite?
Because space isn’t curved they will never meet or drift away from each other. A flat universe could be infinite: imagine a 2D piece of paper that stretches out forever. But it could also be finite: imagine taking a piece of paper, making a cylinder and joining the ends to make a torus (doughnut) shape.
How long does it take light to travel through the universe?
That’s because we know the universe isn’t infinitely old — we know the Big Bang occurred some 13.8 billion years ago. That means that light has had “only” 13.8 billion years to travel.
Is the universe flat or curved?
Measurements taken by satellites have pointed to the universe having a flat geometry. In a flat universe, two light beams shot side by side through space will stay parallel forever, and will never cross or drift apart. In this sense, we can still think of a cylinder or torus (donut) shaped universe as being “flat”.
