Oldest galaxy is lone ranger

Discovery of the most distant known object hints at empty early Universe.

Astronomers have glimpsed the most distant galaxy ever detected — a lone object 13.2 billion light years from Earth. The discovery implies that the fledgling Universe was emptier than was previously imagined.

The galaxy was spotted in the Hubble Ultra Deep Field, an infrared image of the night sky that contains the faintest and farthest objects so far pictured. The finding "pushes the data to the very limits", says Rychard Bouwens, an astronomer now at Leiden University in the Netherlands and a co-author of the study, which is published today in Nature.

I still find it amazing that we can look that far into deep space. Won't be that long before we view the very edges of our known universe.

Just pointing out that there is something like a"light barrier" - we cannot look farther than light had time to travel in the time since the Big Bang. Thus one need to make a distinction between the "total universe", and the "observable universe", which according to estimations maybe make just 4% of the total universe.

I also point at the idea of "fluctuating" universe, meaning that a Big bang forms an expanding universe, expansion turns into retraction and final collapse of all thing in one single point - and that marks the next Big Bang and the cycle begins from start.

The problem of astronmy and physics with Big Bang and empty voids, a noithingness, is, that a "nothing" despite being nothing and being beyond any content and characteristics, nevertheless must have such features and characteristics that makle this nothing suddenly causing something and giving birth to time and energy. this is the line that marks the beginning of territories that neither science nor relgions do have explanations for. Science cannot explain it and is never much concerned about the questions of "Why?", only about "How?". Relögions just claims something without any ground or basis and takes that arbitrary claim as "truth".

The truth is that there are things that we simply do not know, scientists and religious people all alike. The option that recommends itself here is: to just admit that.

Have rough knowledge of this, but we can "listen" at least to some of the furthest regions of the universe with radio telescopes. Anyways, lets not get into a in-depth discussion about the complexities astrophysics, and lets be amazed at the wonders of the universe .

Radio waves travel at the same speed as light so the Light Barrier is also the Radio Telescope Barrier.

Whether there is a Divine creator or not, either way, the implications are staggering.

The Universe we barely understand is mind blowing already. Imagine if we understood even an iota more than we do today.

"Space... is big. Really big. You just won't believe how vastly, hugely, mindbogglingly big it is. I mean, you may think it's a long way down the road to the chemist's, but that's just peanuts to space."

Kasterborous was the constellation Gallifrey is in not the name of the Galaxy it resides in.

You're right, I though of galaxy when the name pop up...

That's the citadel with the panopticon on top!
Gallifrey is more like this:

The second oldest galaxy in the universe just happens to be a native named Tanto.

Thus, the oldest galaxy in the universe often goes by the nickname "Kemosabe".

It sometimes baffles my simple mind as to how they know just how old this galaxy is.

You can't just "pull it over and ask for its ID".

I'll go back to learning how to text now...
