As astronomers delve deeper into the cosmos, they uncover that a staggering 95% of the universe is composed of dark matter and dark energy, two enigmatic forces that remain largely unobserved. These substances not only influence the universe’s structure but also drive its accelerated expansion,challenging our understanding of physics. Upcoming missions, including NASA’s Nancy Grace Roman Space Telescope, aim to map dark matter and explore the implications of dark energy, possibly unlocking the secrets of the universe’s hidden components.

Q&A with Dr. Emma Stokes, Astrophysicist at NASA
Time.news Editor: Welcome, Dr. Stokes! With recent discoveries suggesting that a remarkable 95% of the universe is composed of dark matter and dark energy, can you explain what these terms mean and why they are so significant to our understanding of the cosmos?
Dr.Stokes: Thank you for having me! Dark matter and dark energy are two of the most perplexing aspects of our universe. Dark matter is a form of matter that doesn’t emit or interact with electromagnetic radiation, making it invisible and detectable only through its gravitational effects. It’s crucial for the formation of galaxies and their structures. Conversely,dark energy is a mysterious force driving the accelerated expansion of the universe. Together, they fundamentally shape cosmic dynamics and push us to question the laws of physics as we certainly know them.
Time.news Editor: That’s intriguing! How do scientists investigate these elusive components, and what role will upcoming missions, like NASA’s Nancy Grace roman Space Telescope, play in this research?
Dr. Stokes: The Nancy Grace Roman Space Telescope is designed to provide us with unprecedented views of the universe. By mapping the distribution of dark matter through gravitational lensing—where light from distant galaxies is bent by dark matter—we can infer its presence and behaviour. additionally, it will meticulously observe supernovae to refine our understanding of dark energy’s effects. These efforts could perhaps unlock critical insights into how these forces influence cosmic evolution.
Time.news Editor: Given that dark matter and dark energy challenge our fundamental understanding of physics, what are the broader implications of these findings for the scientific community and our understanding of reality?
Dr. Stokes: The implications are profound. If we can accurately map dark matter and understand dark energy’s role in cosmic expansion, we may also redefine aspects of fundamental physics, including concepts of gravity and space-time. This research could lead us to new theories that better explain cosmic phenomena and even provide a framework for new technologies.
Time.news Editor: For our readers who are fascinated by space exploration and want to keep up with advancements in this field, what practical advice can you offer?
Dr. Stokes: I encourage readers to engage with the cosmos—there are many accessible resources online, including NASA’s websites and public lectures. Participating in citizen science projects related to astronomy can also be incredibly rewarding. Lastly, keeping an eye on upcoming missions like the Roman Space Telescope will provide insights into discoveries that could reshape our understanding of the universe.
Time.news Editor: Thank you, Dr. Stokes, for your insights into dark matter and dark energy. We look forward to the exciting advancements that the field of astrophysics will bring!
Dr.Stokes: it’s my pleasure! The more we explore, the more we learn about our universe, and I’m thrilled to be part of this journey.
