The scope is detecting light that hasn’t got to us yet

It’s all relative…

Whoa. # BillAndTed
In the 7 minutes it took you to read this article, the Universe has expanded sufficiently so that another 15,000,000 stars have crossed that critical distance threshold, becoming forever unreachable. They only appear to move faster than light if we insist on a purely special relativistic explanation of redshift, a foolish path to take in an era where general relativity is well-confirmed. But it leads to an even more uncomfortable conclusion: of the 2 trillion galaxies contained within our observable Universe, only 3% of them are presently reachable, even at the speed of light.

If you go outside at night and turn on a flashlight and point it in to space then turn it off someone in another galaxy is seeing that light long after you turned the flashlight off because it took so long for that light to travel to them.. in this case billions of years.. The flashlight is off and you are long dead by then..
Go that way really REALLY fast. If something gets in your way, TURN!

^^ I can’t give the answer to that for sure (maybe someone else can), but I do have an issue with that graphic that mud posted. On the far right, where it says “Big Bang”, there are specs of light. There was no light until the the first stars formed. The Big Bang was dark.

Oh, here’s a link that does explain it. Turns out the the Big Bang is in every direction from us.

That's why they call it background radiation.
It's a war of the mind and we're armed to the teeth.

And that’s the really mind boggling part in a nutshell. The 14 billion year old universe is 93 billion light years “across” yet the speed of light has somehow not been exceeded (due to the expansion of space-time, yada yada).
Said another way, that matter has only been traveling at 1-2% of the speed of light for 14 billion years yet it is 90 billion light years away.

Once you realize birds aren’t real.
Then anything is possible

For some perspective. Voyager 1 has been traveling 40,000 miles per hour outwards into the universe since 1977 and hasn’t even reached a distance of 1 light day yet.

The explanation is somewhere in here... I think...
Aim for the chopping block. If you aim for the wood, you will have nothing. Aim past the wood, aim through the wood.

I had to look it up, kind of odd a forbes article was what I found...expanding fabric of space.

If you really want to get weird start listening to Donald Hoffman: https://www.scienceandnonduality.com...donald-hoffman

I'm still all in on the rubber band theory... The big bang has happened an infinite number of times.. over and over... EXACTLY the same way with exactly the same matter. BOOM!!!>>>>> EXPANDS until the limits of gravity and physics are reached then it collapses on itself again until BOOM!>>>>>>>>>>>>> over and over and over for eternity...
And every one of us has done exactly what we're doing right this second exactly the same way, every thing everyone everywhere in the universe each and every time over and over because the conditions leading up to this moment happen exactly the same way each iteration.. over and over..Go that way really REALLY fast. If something gets in your way, TURN!
