Why is the universe not 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). The observable universe is centred on us.

How can the universe be infinite if it is expanding?

Although space may have been concentrated into a single point at the Big Bang, it is equally possible that space was infinite at the Big Bang. In both scenarios the space was completely filled with matter which began to expand. There is no centre of the expansion, the universe is simply expanding at all points.

What made Newton conclude that the universe was infinite?

Newton also believed, according to his theory, that the Universe was static and infinite. According to it, the matter in the Universe was in balance because its distribution was uniform and infinite, in such a way that each of the stars is balanced with its neighbors, by the entire universe.

Is the world infinite or finite?

No. We do not know whether the Universe is finite or not. To give you an example, imagine the geometry of the Universe in two dimensions as a plane. It is flat, and a plane is normally infinite.

Why does the universe need to expand?

Because this energy is a property of space itself, it would not be diluted as space expands. As more space comes into existence, more of this energy-of-space would appear. As a result, this form of energy would cause the universe to expand faster and faster.

Who said that the Universe is finite and eternal *?

Sometime between 1666 and 1668, in an unpublished manuscript that we refer to by its opening words, De gravitatione, Newton wrote that an “infinite and eternal” divine power coexists with space, which “extends infinitely in all directions” and “is eternal in duration.” Descartes claimed that where there is no matter …

What did Newton say about all mass in the Universe?

Newton’s universal law of gravitation states that all masses in the Universe are attracted to each other. In General Relativity, masses – and even light – move along straight lines in the curvature of space. Another consequence of mass in General Relativity is that it leads to time dilation or a gravitational redshift.

Is the universe infinite or finite?

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.

How can the universe be infinite if it started expanding?

How can the universe be infinite if it started expanding 13.8 billion years ago? 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.

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.

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.
