Is the universe really one big black hole?

Recent theories suggest that the universe could be conceptualized as a giant black hole due to its vast empty spaces, challenging traditional views of cosmic structure.

• Astronomers propose that as black holes grow larger, their average density decreases, prompting the idea that the universe might function similarly within its expansive voids.
• Current understanding of general relativity indicates that the event horizon of a black hole defines its boundary, raising questions about the universe's own gravitational limits.
• The exploration of this concept could redefine our understanding of galaxies and the cosmos, potentially leading to new insights in astrophysics and the nature of gravity.
