New research has offered a stunningly insightful perspective into the existence of dark matter, the universe’s most elusive cosmic phenomenon. According to the new study, it could well be the underlying force behind the dramatic pattern of successive extinction events, which ultimately ushered in the emergence of man on the planet. It continues to remain a decisively problematic aspect of present day scientific inquiry.
Decades ago, scientists employed NASA’s Hubble Space Telescope to uncover the then surprising expansion of the universe. In the process, they concluded that a mysterious source of concealed dark energy had been the principal triggering force behind the phenomenon. According to experts, it constitutes more than 60 percent of the total energy of the universe.
Since then, numerous studies have been carried out in an attempt to grasp the largely inexplicable mechanisms of dark matter. Many studies suggest that dark matter is somewhat central to the composition of the universe, while some experts have argued that it may quite simply be a product of a number of suppositious elements working stealthily across a galactic heart of darkness. Dark matter can only be indirectly comprehended by observing its subtle influence on the myriad patterns of ordinarily observable cosmic matter.
Lisa Randall, a researcher at Harvard University, argues in her latest book that the extinction of the dinosaurs; central to the subsequent origin of humans on earth is linked to this mysteriously obscure matter that astronomers believe constitutes nearly 90 percent of all matter in the universe.
“In some global sense, we are all descendants of Chicxulub [the town where the dinosaur-killing meteor impacted]. It’s a part of our history that we should want to understand. If true, the additional wrinkle presented in this book would mean that not only was dark matter responsible for irrevocably changing our world, but also that some of it played a crucial role in allowing our existence.”
According to experts, there is convincing evidence to support dark matter’s endless gravitational influence on the universe. It is typically believed to be concentrated in extensive halos around floating galaxies. According to Randall, there could also be a dark disc amid the stars, their orbiting planets, and dust ubiquitous in our own galaxy, the Milky Way.
Dark matter does not interact directly with electromagnetic or nuclear forces. Light does not bounce off of it, and ordinary matter permeates it in only the faintest of exchanges. Fundamentally imperceptible, it exerts tremendous influence on the motion of galaxies and galactic clusters, providing plausible evidence of its dormant existence.
According to another latest report, a new space telescope will soon attempt to glance into the emptiness of “near space” and obtain answers to its unexplained, puzzling anomalies.
The CALorimetric Electron Telescope (CALET) investigation will spearhead the mission to observe the trajectory of cosmic ray particles and calculate their charge and energy as explained by researcher Dr. Shoji Torii.
“The investigation is part of an international effort (involving Japan, Italy and USA) to understand the mechanisms of particle acceleration and propagation of cosmic rays in the galaxy, to identify their sources of acceleration, their elemental composition as a function of energy, and possibly to unveil the nature of dark matter,”
More recently, scientists have proceeded to study why dark matter has not yet been evidently spotted during “Earth-based experiments.” Others have speculated if it could actually contribute to an ultimate collapse of the universe. Despite the fact that nearly 90 percent of the entire composition of the universe primarily constitutes dark matter, scientists suspect whether it could possess enough gravity to thwart the expansion mostly owing to convincing observations that suggest that the expansion is still accelerating as of now.
