What does it mean if the Universe is infinite?

To be clear, a truly infinite universe means that anything that is not impossible (no matter how obscure) will happen, must happen and must happen, weirdly, an infinite number of times.

Is it possible that the Universe is 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).

How can the Universe be infinite if it has a beginning?

If the universe is infinite, it has always been infinite. At the Big Bang, it was infinitely dense. Since then it has just been getting less dense as space has expanded. Imagine a large flat rubber sheet with sand placed as closely together as possible on the sheet.

Are there an infinite number of ideas?

An idea is a thought, plan, notion formed in the mind. The same way as one species gradually evolves and a new species is formed, so too can an idea evolve; thus, for both biological evolution and the evolution of ideas, or memes, the possibilities are infinite.

Is there an infinite number of 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.

Is there an infinite number of possibilities in the universe?

Our existence is inherently defined by boundaries and limitations, so an “endless” number of possibilities is inconceivable. However, if the universe is infinite, then there is a probability (however small) that the exact same arrangement of atoms and molecules exists elsewhere.

Is the universe infinite or infinite?

Is The Universe Infinite? Could It Be Infinite? There remains no clear or definitive evidence that the universe is either finite or infinite, although there are some intriguing arguments and proposed theories on both sides.

How many galaxies and planets are there in an infinite universe?

So there would be an infinite number of galaxies and planets in an infinite universe. If however there is an infinitesimal probability of something happening, then in an infinite universe there would only be a finite number (for example 1) of those things.

Is there a definitive answer to everything in the universe?

Scientists and academics like firm answers and measurable quantities, but when you’re talking about the largest conceivable scale (the entirety of the universe), such definitive answers are often elusive, or impossible to ever prove.
