This document was part of NASA’s 2003 roadmapping effort required under the Government Performance Results Act of 1993 (Public Law National Aeronautics and Space Administration, Beyond Einstein: From the Big Bang to Black Holes, Washington, D.C., January 2003. National Aeronautics and Space Administration, Beyond Einstein: From the Big Bang to Black Holes, Washington, D.C., January 2003, That has greatest promise of elucidating the nature of dark energy is the determination of its cosmic evolution.ĭetermining the size, shape, age, and energy content of the universe is also necessary in order to constrain the Understanding the nature of dark energy is the most pressing question in cosmology today. What happens to gas and stars as they are swallowed by black holes. Very near a black hole by observing distortions of spacetime near its event horizon. A third objective is to probe what happens in the very strong gravitational field

Thus, two of the research goals associated with black holes are to perform a census of black holes and to determine To understand how black holes affect space, time, and matter in the universe, one must first determine howįrequently they occur, what their properties are, and how they interact with matter in galaxies and other structures. Progress on this question will also be made by determining the size, shape, age, andĮnergy content of the universe, which will better constrain conditions during the big bang. Gravitational radiation, and a specific goal is to detect the level of this radiation, either directly or through its The universe expanded by some 30 orders of magnitude in linear scale. Investigating what powered the big bang requires probing the period of inflation, an early era when The Beyond Einstein roadmap lays out specific research goals related to each of the three fundamental ques. Missions that harness the ingenuity, creativity, and technical sophistication of current and future generations. Investigating the nature of these phenomena—going beyond Einstein—will take space Einstein’s general relativity equation contains a term associated with a “cosmological constant” that Įinstein’s theory of general relativity predicted the expansion of the universe from a big bang and the phenomenon Pulling the universe apart? These fundamental questions lie at the heart of NASA’s Beyond Einstein Program. What powered the big bang? What happens to spacetime near a black hole? What is the mysterious dark energy Because it is UNCORRECTED material, please consider the following text as a useful but insufficient proxy for the authoritative book pages.
