Two of the Universe's Great Mysteries May Have Their Own Dimension
Recent astronomical data suggests that dark energy and dark matter may be physically linked rather than separate entities. Researchers are investigating whether dark energy's changing strength is influenced by its interaction with dark matter.
Why it matters
Understanding the relationship between these two mysterious components could fundamentally reshape our knowledge of the universe's expansion and physical laws.
For those who see the world as a dark place, the universe seems to offer little solace. According to current estimates, approximately 70 percent of the stuff that makes up the cosmos consists of dark energy, an unknown force that pushes space to expand. And another 25 percent consists of dark matter, a mysterious material that holds galaxies together.
But semantically speaking, dark energy and dark matter are not so much “dark” as they are invisible. They do not emit, reflect, nor absorb light, and they have so far proven impossible to observe directly.
Generally, dark energy and dark matter are regarded as separate entities, their elusiveness their primary link. But recent astronomical observations have spurred scientists to look further into a less popular idea—that the two are in fact physically intertwined.
