Basically space is expanding so fast it’s decreasing our render distance

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?
-
To clarify (I had to google this up to confirm), when Don says our visible universe is 46 bya, that's in one direction. So the sphere of visible-ness is 93 b light years across.

Who else or is it just me who enjoys topics as this, but really understand very little at the end? Lol

if everybody leaves their toast in for 8 minutes....this could account for most of the dark matter in the universe

Probably, this 10 minutes long video was the most eye openining video I have ever seen on youtube. What a great explanation. Amazing. Thank you.

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!

I like to toast my bread for about 30-35 minutes
-
Superb explanation, thanks!
-
This is a mind blower. Great video. Thanks.
-
Short answer: The universe is expanding faster that the speed of light.
-
I usually toast my bread for 8 minutes until it’s a crisp charcoal black
-
Recent studies suggest universe is actually 26.7 billion years old

E.T. Tries to phone home: “... the number you have dialed is out of your reach...” 😢

He gives us a professional lesson and all we take in from it is that he leaves his toast in the toaster for wayyyy too long
-
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.

The short explanation: Universe is expanding

He can tell you the age of the universe, but don't ask him how long to toast bread.
