Are there infinite possibilities in the universe?

The universe may be infinite, but we can only see a finite section of it due to the finite speed of light. 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.

How infinite is the universe?

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).

Do all possibilities exist?

Scientists claim with this theory that all possibilities exist in one of the infinite universes that constitute the multiverse. If all possibilities exist, then by this theory there exists a universe in which multiverse theory does not exist (both as a theory and as a governing physical law).

Can there be more than one universe?

There is not one universe—there is a multiverse. In Scientific American articles and books such as Brian Greene’s The Hidden Reality, leading scientists have spoken of a super-Copernican revolution.

What are the odds of finding life on other planets?

While the chances of finding life elsewhere remain unknown, the odds can be said to be improving. A well-known list of the data needed to determine the likely abundance of life-bearing worlds, though highly conjectural, is known as the “Drake equation.” Put forward in 1961 by astronomer Frank Drake, the list remains mostly blank.

Are We the only life-bearing worlds?

In a galaxy that likely holds trillions of planets, ours is so far the only known life-bearing world. Are we really alone? Life in the Universe: What are the Odds?

Are We ‘Home Alone’ among trillions of planets?

Among the stunning variety of worlds in our solar system, only Earth is known to host life. But other moons and planets show signs of potential habitability. Among Trillions of Planets, Are We ‘Home Alone?’ In a galaxy that likely holds trillions of planets, ours is so far the only known life-bearing world.

What is the origin of life in the universe?

It begins with the rate of star formation in the galaxy and the fraction of stars that have planets, leading step-by-step through the portion of planets that support life and – most speculatively – to the existence and durability of detectable, technological civilizations.
