Are they looking in our Galaxy and not galaxies a long time ago and far far away

These scientists sound so foolish when they say the big bang occurred 13 billion years ago. The furthest lights are 13+ billion light years away, so they assume the galaxy is 13+ billion years old. To get that, you have to assume:
1. that galaxies travels at or near the speed of light. They don’t, so it may have taken them long to get to where they are, or were when the light we see started.
2 You have assume we are at the center of the universe, since we can see galaxies at that distance in all directions.

How can we assume light from the furthest seen galaxy to our west hasn’t reached the furthest seen galaxy to the east? That would make the universe at least 26+ billion light years wide.

My guess is that they’ll concentrate on the Milky Way first. Plenty of pickings there!

Your ignorance of astronomy and the age of the universe is astounding.

The Big Bang THEORY. How did everything we know at present begin? Scientist THINK it began 13.8 billion years ago, and some THINK it started with a BIG BANG. I haven’t seen any of those ”scientists “ expound on where the matter, or the energy came from, andwhat “triggered” the BANG. There is a lot more unknown than known.

You might start your education by researching Hubble Constant and CMB.

They have. Do your homework.

Scientist calculated it began 13.8 billion years ago,

That's one of the most perplexing things about the Big Bang theory! Objects having mass can't travel faster than the speed of light. But the speed at which space itself can expand has no such speed restriction.

I recently read that within a few seconds of the Big Bang the universe was already 20 or 30 light years across. And in that hyper-expansion, it carried all the objects embedded in it along for the ride. Those ojects were not moving through space faster than light. They were moving with space. And Einstein has nothing to say about how fast space can expand.

That changes everything in your calculations, and mine. Apparently (I don't claim to understand it), because of this hyper-expansion of space, the universe itself may be much larger than 26 billion light years across.

Hundreds of billions? Maybe. Infinitely large? I've even read that, though I don't see how that's possible!

The most distant galaxies are traveling away from us faster than the speed of light.

"93 BILLION LIGHT YEARS"

Just think how far light will travel in one year. It's mind-boggling.

Mind-boggling like this:

Lawyer: “Ok, why don’t you start at the beginning”.
Witness: “Well, about 2 billion years ago the earth’s surface cooled a crust formed.”
Lawyer “Maybe not that long ago...”

So, Tex, Tell me again the one-way speed of light? Einstein couldn’t nor wouldn’t try. He understood that we can only derive a round trip SOL, so knowing just how light acts in reality, is, well, beyond us. A convention agreed upon because knowing, not just assuming, is not possible given both technology and constraint. All of the facets of physics simply tell us, “whoa, there fella, my secrets are mine”.

“In the Beginning (of time)... God said, “let there be light, and light was””. Ought to make us think about light in a different, well, light.

And, to those who will say it has to be uniform, the correct answer is no, it only has to be seen as consistent from application to application, and observation to observation.

Most of astronomy has passed from observation to supposition and assumption; and, heaven help us, consensus.

But I defer to those who spend much more time on the subject, as to breadth of training and assumption, not truth, necessarily.

“2 You have assume we are at the center of the universe, since we can see galaxies at that distance in all directions.”

Exactly opposite. It is assumed that the universe has no “center”.

There are theories about how the Big Bang came about. Mostly they have to do with either Black Holes spawning new universes and ours was spawned by a Black Hole from a previous universe, or the Big Bang is part of an endless cycle of inflations and collapses of our universe.

There is also this theory about it all being started by God.
