Using information from a suite of telescopes, astronomers have discovered a mysterious, giant object that existed at a time when the universe was only about 800 million years old. Objects such as this one are dubbed extended Lyman-Alpha blobs; they are huge bodies of gas that may be precursors to galaxies. This blob was named Himiko for a legendary, mysterious Japanese queen. It stretches for 55 thousand light years, a record for that early point in time. That length is comparable to the radius of the Milky Ways disk.

  • At initial expansion the force from the zero point was greater than the gravity of the hydrogen.

  • That would be intuitive but theres a thing called jeans instability, basically that means a hydrogen nebula can only get so big before it collapses under its own gravity and begins fusion. This blob is almost as far out as we can see and it still appears as large as galaxies that are 1/10th the distance.
