Latest Vacuum energy Stories
Quintessence and phantom fields, two hypotheses formulated using data from satellites, such as Planck and WMAP, are among the many theories that try to explain the nature of dark energy.
When we talk about the vacuum of space, we imagine a complete lack of matter – a cold void, dark, and absent of all energy. Over the last century, however, physicists have come to realize that the emptiness of space is anything by empty.
Inflation -- Inflation is the idea - first proposed by Alan Guth (1981) - that the nascent universe passed through a phase of exponential expansion that was driven by a negative vacuum energy density (positive vacuum pressure). This expansion can be modelled by a non-zero cosmological constant. As a direct consequence of this expansion, all of the observable universe is posited to have originated in a small, initially causally-connected region. Quantum fluctuations in this microscopic...
