Discussion Overview

The discussion centers around the discovery of a giant space "blob" observed in the early universe, approximately 800 million years after the Big Bang. Participants explore its characteristics, potential implications, and the challenges of observing earlier cosmic events.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • Some participants express curiosity about the blob's characteristics and its unusual nature, with one participant noting it emits a certain type of radiation.
  • There is a light-hearted suggestion to name the blob "Hubert" or "Mother," reflecting a playful engagement with the topic.
  • One participant questions whether the blob's youth might correlate with anisotropies in the Cosmic Microwave Background (CMB).
  • Another participant raises the idea of looking further back in time to observe the Big Bang, but acknowledges the limitations imposed by the opacity of atoms during certain epochs.
  • A later reply suggests that while electromagnetic radiation is opaque, neutrinos and gravitational waves could potentially provide insights further back in time.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the implications of the blob's discovery or the feasibility of observing earlier cosmic events. Multiple viewpoints regarding the nature of the blob and the observational limits of the early universe are presented.

Contextual Notes

The discussion highlights limitations related to the opacity of the universe during certain epochs, which restricts observations of earlier times, as well as the varying interpretations of the blob's significance.

WASHINGTON - A strange giant space “blob” spotted when the universe was relatively young has got astronomers puzzled.

Using space and ground telescopes, astronomers looked back to when the universe was only 800 million years old and found something that was out of proportion and out of time. It was gaseous, big, and emitted a certain type of radiation, said study lead author Masami Ouchi, an astronomer at the Carnegie Observatories in Pasadena, Calif.

Scientists don’t even know what to call it. So they just called it a radiation-emitting “blob.”...

It is an interesting discovery. Only further observation will tell the tale.

"Hubert" :biggrin:

The friend who sent the link to me called it, "Mother". :biggrin:

Got to love a good blob.

"More formally, they named it Himiko, after a legendary ancient Japanese queen."
Drats, I don't like that name.
 
If this thing is so young, would there be any expectation of it "lining up with" an anisotropy in the CMB?
 
Now why don't they look a little further back in time to see the big bang :)

They do look further back, but there was an epoch in time when atoms were opaque to EM radiation. This is a cut off point. You can't see any further back than that (so you can't actually see the big bang).
 
The early universe was only opaque to em radiation, neutrinos could push the limit much further back, and gravity waves - perhaps all the way back.
