If the universe is only 14 billion years old, how can it be 92 billion light years wide?

The size and age of the universe seem to not agree with one another. Astronomers have determined that the universe is nearly 14 billion years old and yet its diameter is 92 billion light years across. How can both of those numbers possibly be true? In this video, Fermilab’s Dr. Don Lincoln tells you how.

  • I admit to not knowing much - but I am confused. - If the universe started with a big bang - then it started from a point and everything radiated outwards - in every direction (my mind can only comprehend a sphere here). Shouldn't then the background radiation and the light be coming at us, the planet earth, from one direction only? I know that the earth is revolving, the sun is revolving and presumably our galaxy is moving - perhaps revolving - but at any one point in time the radiation should be approaching from one direction only. Why does he say that the planet earth is in a sphere, with light and radiation coming at us from every direction?

(in a sort of dumb bugger basic way) ... light is a particle ...space is not a particle ... the fastest speed a particle can move is the speed of light ..... inflation of space can and does happen faster than the speed of light (light is suspended in the space) sort of anyway

  • How be it, I agree they did not give us nearly correct info on ages or time for distance, you likewise are making false assumptions, your conveniently avoiding primary subject matter that are obvious foundations for such arguments. So nothing you wasted time speaking of proves anything simply because it is not according to reality provable facts provided or often with out contradiction science facts or universal laws of science, backed by tested by many and considered true and concrete as evidence. Nope at best all of what you said is hardly even close Observational science. Physical testing or hands on testing has not nor can be spoken of seriously even as being true or nonfictional in such matters like this. For example it's ridiculous to say something like , "what proves my space station, shaped like a guitar case, is far more functional than Darth Vader's Death Star, is the fact that Ewoks first developed the blueprints to space stations with electro- magnetic plasma technology rather than the older stations which relied on, prehistoric in origin, a fission or fusion processor as the inner power core". No aside the ridiculous to most claim I just made, if you or I didn't already know that the Star Wars creation is a work of George Lucas and other HollyWood ( Heads,) which I should add spellcasting or spells is originally done with wands made of the Holly of the Holly tree made of (wood), than it wouldnt seem at all the completely bogus crap material that it trully is but instead like the crap your passing isn't even considered observational in close evaluation or in-depth closely monitored science to be seriously taken into consideration towards Basic Laws of Science or The Universe or even of Nature, often pressumed to be fact, or hardly accepted. Nope a saying like, "we won't get into What even created the Universe is avoiding concrete foundations towards the fact you are debating over. Very childish and unproductive at best! Oh, and we shouldn't waste our thoughts on debating fake news or fictional facts anyways. Shhhhhhh, BESIDES The Earth is FLAT!

  • I haven't watched the entire video yet so maybe you touched on it. But I'm curious. If the universe began with the singularity and exploded, wouldn't it expand in all directions ? When we look out and measure the universe aren't we only looking in a single direction ? If the universe is 92 billion light years across, does that mean its 46 billion light years in one direction and 46 billion in the opposite ? I'll finish watching this later to see what you say, gonna take the family to see Spider-Man, which is only 1/6,000,000,000,000th of a light year away, i think.

  • Two questions: Is there any way to determine the true center of the universe, i.e. the point from which it expanded at the time of the Big Bang? And if so, where is Earth in relation to the true center of the universe?

  • This video assumes the earth is the center of the universe and everything is expanding away from it. Not too long ago we thought the earth was the center of our solar system and everything revolved around it. This was proven wrong and so too is the assumption the earth is the center of the universe. The literature denotes the Big Bang as happening everywhere at the same time. I think this is physics speak for they don't know.

  • How can one possibly say that early stars in the universe can't be seen because space is expanding? That makes ZERO sense.

    • it's very simple. Consider a super sonic jet. Once it flies by you, you don't hear it anymore, because it is travelling faster than the speed of sound. It's the same effect just with light instead of sound

He could have created a universe billions of light years wide 'ex nihilo', simply by speaking it into existence. Then everything was already in place for man to ponder it's origin! Lol

    • He could also have created the earth as being millions of years old, complete with dinosaur fossils, sediment layers, continental drift, etc. Makes you wonder...

  • Back in Copernicus' day, back around 1500 AD; the prevailing thought at the time was that the Earth was the center of the Universe. Astronomers who believed this idea about the Earth being the center of the Universe were mathematically sophisticated enough that they could provide a mathematical framework to attempt to explain the motion of stars and the movements of planets and the Sun around the Earth. These mathematical models were sophisticated, they were very convoluted, and they were *extremely* complex; but they described the cosmology of the known universe, at the time. These models *HAD* predictive power, after a fashion; but they were all missing an important detail about the nature of the Universe that most astronomers at the time didn't know. Sometimes I wonder if concepts like "Dark Matter", or "Dark Energy" are the modern equivalent of the prognostications from Copernicus' time, just missing the important detail needed to make the concepts of our local cosmology click correctly into place. Some detail as simple as gravity doesn't behave on a scale of 100s of light years the way that our models currently describe it should could put a nail in the Dark Matter/Energy coffin. This is interesting... (I'm not suggesting it's more correct either, I am just suggesting that there are multiple different ideas and that the science is not settled, yet) phys.org/news/2019-01-dark-alternative-theory.html

Perhaps by then that form of travel will be virtual and detached from our bodies which have long since crumbled to dust, but so realistic that it will in essence be reality.

For as the heavens are higher than the earth, so are my ways higher than your ways, and my thoughts than your thoughts.10 For as the rain cometh down, and the snow from heaven, and returneth not thither, but watereth the earth, and maketh it bring forth and bud, that it may give seed to the sower, and bread to the eater:11 So shall my word be that goeth forth out of my mouth: it shall not return unto me void, but it shall accomplish that which I please, and it shall prosper in the thing whereto I sent it. don't look to the world system for understanding for it will lead you astray trust in Jesus with all your heart and he will light your way I am the way truth and the life no one comes to the father except by me Jesus

  • You should tell that Universe is at least 92b light years across. Earth is not the center of Universe. I think it is boundless. Why is the mechanism of Universe made that way that space is expanding? Why does the speed of expanding change and would it change in the future? There's no logic of this, because this is regression. The problems of Universe are barely problems of humanity at this stage, but looks like Universe is not made for eternal progress. The laws of its existence and progress doesn't look to be really fitting the needs and possibilities of humanity.
