Is the universe infinite in size?

The shape of the universe A finite universe has a finite size that can be measured; this would be the case in a closed spherical universe. But an infinite universe has no size by definition. According to NASA, scientists know that the universe is flat with only about a 0.4 percent margin of error (as of 2013).

What does it mean that the universe is infinite?

It means space never ends. It’s a matrix of limitless galaxies, stars, planets, and energy. California Institute of Technology theoretical physicist Sean Carroll cautiously noted last spring that while a finite universe would be provable, scientists can never prove infinity.

Is endless the same as infinite?

Endless -> that which does not appear to have an end in time or space. Infinite -> that which is large and not limited by a definite number or quantity; In the factory, there was the endless noise of machinery -> endless = continuous (over a long period.)

Is there an infinite past?

Since there’s no negative infinite number, there’s no infinitely past year or earliest year. There never was a time when the past became infinite because no set can become infinite by adding any finite number of members. So, if the past is infinite, then it has always been infinite.

Did Einstein say the universe is infinite?

Originally Answered: Albert Einstein says “Two things are infinite: the universe and human stupidity; and I’m not sure about the universe” but I think so is perfection? Einstein NEVER said that. Nor would he have ever said such a thing. First, Einstein did not believe the Universe was infinite.

What is the size of universe?

93 billion light-years
The observable Universe is 93 billion light-years in diameter. Some scientists believe its true size is even scarier than that. By using the Bayesian model averaging, scientists estimated that the Universe is at least 250 times larger than the observable Universe, or at least 7 trillion light-years in diameter.
