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

if everybody leaves their toast in for 8 minutes....this could account for most of the dark matter in the universe
-
Basically space is expanding so fast it’s decreasing our render distance
-
The more I learn about this, the more convinced I am that we really have no idea what we're talking about.

Excellent video. Earned a new sub.

So basically he is saying that we will never ever know how really big the universe is. It’s because we can’t see anything that is beyond 15Billion light years due to the expansion of universe is faster than the speed of light. The fact that we are loosing 20k stars per seconds on our line of sights speaks how fast the universe is expanding. This is very fascinating!

You say “Nothing travels faster than light.” However, I recall from Doug Adams’s “Hitchhikers Guide to the Galaxy” that their spaceship was powered by “bad news” because “nothing travels faster than bad news.” Of course, wherever they went, they were not welcome. Thanks for the clever video.

If the universe is so big, why won’t it fight me?
-
This is a mind blower. Great video. Thanks.
-
Who else or is it just me who enjoys topics as this, but really understand very little at the end? Lol

I usually toast my bread for 8 minutes until it’s a crisp charcoal black
-
One question - is the speed of light constant between 'now' all the way back to the Big Bang? That is to say, if we somehow had a view from "outside" the universe, would we see the speed of light drop dramatically from the instant of the BB, gradually leveling out to its present value here/'now'?

Thanks Don. This is one of my favourite videos.!! Can someone clarify me this: If CMB radiation that arrives today to us was emitted 13,7 b years ago at a distance of only 42 million ly, does this means that all galaxies we see today (even the most distant) were closer than 42 million ly when the radiation was emited?
-
I like to toast my bread for about 30-35 minutes
-
Short answer: The universe is expanding faster that the speed of light.
-
Dude, that toast was way too dark
-
I always wanted this question answered. It was never explained to me on TV how we could see the beginning of the big bang. I couldn't get my head around it as surly the light had already passed us. Thanks for the explanation but will need to watch a few times.

E.T. Tries to phone home: “... the number you have dialed is out of your reach...” 😢
-
He can tell you the age of the universe, but don't ask him how long to toast bread.

Great video!!

Since the universe is expanding, light from distant stars takes longer to reach earth, since the speed of light is determined only relative to the source, not the object. So the distance between earth and any distant star can't be accurately calculated unless we know the relative speed between earth and the star.
