Science says the universe is 12 to 14 billion years old because light from that far away has reached us but couldn't there be objects billions of light years further away?

Yes, current theory and observations suggest that the age of the universe is between 13.6 and 13.8 billion years (earth years).
However please note that a light year is the distance a beam of light will travel in one earth year.

∙ 14y agoIt's even more confusing than that. What astronomers refer to as "the observable universe" is the region of space from which light has had time to reach us; it's a sphere a bit under 14 billion light-years across. However, what we're seeing now is light from objects that were that far away when they emitted the light. Due to the expansion of space, these objects are moving away from us, and objects that were around 13 billion light-years away 13 billion years ago when they emitted the light we're seeing are "now" probably about 45 billion light-years away from us. (That "now" in quotes is because according to relativity there is no such thing as a universal now.)

∙ 15y agoNo. A light year is a measure of distance, not time. So the age of the Universe cannot be measured in light years.
Wiki User
∙ 14y agoThe universe is constantly expanding, and is not known to have an end (an infinite amount of space), so it is impossible to say how many light years are in the universe.

∙ 13y agoA light year is a unit of distance, not of time. A light year is the distance light travels in one year - about 9.5 trillion kilometers.

How do you fix the mistake?
It depends on what you did. You a mistake a billion ways because you can mess up a billions of times and ways
How many galaxies in our observable universe?
There are over 100 billion galaxies (with 100 billion+ stars (each containing 9 planets and 170+ moons)) in each one; as well as asteroid belts and nebulae) in the Big O universe (in reality; Paradigm City is a computer simulation). Their light has taken 13 billion years to reach Earth.
When was the formation of the universe?
The Universe has an age estimated to be about 13.8 billion years.
How many comets are in the universe?
There are estimated to be around a trillion comets in the Solar System. Assuming that to be "typical" and figuring roughly a billion trillion stars in the universe, that means the number of comets in the universe is probably in the vicinity of a billion trillion trillion (ten to the thirtieth power).
How many people live in the Indian ocean today?
Approximately 2.3 billions of people
What advancements were made possible because of the telecope?
Mainly the discovery that the Earth is not the centre of the Universe, that the Sun is only one star in an enormous Galaxy of Billions of Stars and that there are Billions of Galaxies. Also that the Universe is expanding and the theory of the Big Bang start to the Universe 6.5 Billion years ago.
How many stars are in outer space and the universe?
There is no real count because new stars are created from time to time. There are BILLIONS AND BILLIONS (as Carl Sagan might have said). There are billions of stars in our Galaxy and there are billions of galaxies. We don't have a very precise total. The usual estimate is: at least ten thousand billion billion. That's 1022 in scientific notation.
Are there at least 100 billion or more galaxies in the universe?
We are not sure exactly how many galaxies are in the universe. There could very possibly be millions or even billions.
What is the estimated number of galaxies in the universe?
The observable Universe is estimated to have around 1011 (a hundred billion) galaxies. The entire Universe is much bigger than that, but it isn't known how much bigger. Perhaps it is infinite, in which case it might have an infinite number of galaxies.
Is the galaxy solar system universe the largest?
The universe contains billions of galaxies and the Milky Way contains between 100 and 400 billion stellar systems (like the Solar system).
Why does someone believe you when you say there are four billion stars?
There is one star in the solar system and millions to billions of stars in one galaxy and billions of galaxies in the universe. So i see no reason why they should disagree with you.
How many billions in a trilion?
A billion billion.
How many suns are in a galaxy?
Our sun is one of between 200 and 400 billion stars in the Milky Way galaxy. There are literally untold billions of galaxies in the observeable universe. Our sun is just another star among billions of billions other stars. Some of which are known to have planets orbiting them.
Are there at least 10 billion trillion or more stars in the universe?
Nobody knows the exact number of stars, however it is possible that there are billions or trillions of stars.
How can the universe be only some 14 billion years old when it can be contemplated that it could be 20 or 30 or more billions of years old?
The universe is actually about 15 billion years old. I'm not sure where you got the statistic that the Hubble Space Telescope can see 20 billion light years into space; I think you're off by a factor of three or so.
How many millions are there in two billions?
Two thousand of them because two billion is: 2,000,000,000
Is it a few billion or a few billions?
a few billion
