The Universe’s Biggest Nothing: Scientists Discover a Supervoid

Great news: Scientists have discovered the largest known structure in space.

In other news, what they discovered is nothing. A lot of nothing. Scientists have discovered what they call a “supervoid,” and they have found or theorized several facts about it:

  1. It is 1.8 billion light years across

This gaping space could have held 10,000 galaxies.

  1. The region is much colder than the surrounding space

This makes sense, because:

  1. It absorbs energy

When light passes into the supervoid, it loses energy, exiting it at much longer wavelengths than when it entered.

  1. It also holds less matter

It holds about 20 percent less matter than the areas around it.

  1. We have no idea why it exists

The supervoid is confusing. While small voids do exist, usual Big Bang theories do not explain why such a large hole should appear.
