Research of Galaxies Supports Einstein’s General Theory of Relativity — VOA Learning English
Topics: наука й природа
Beginning
An international group of scientists has been studying how the structure of the universe has grown over the past 11 billion years.
These researchers recently announced findings about how gravity behaves at a very large scale. What they found supports a prediction physicist Albert Einstein made in his 1915 theory of general relativity.
Dark energy and gravity
The findings are part of a years-long study of the history of the universe that has focused on dark energy. Dark energy is an invisible and mysterious force that is accelerating, or speeding up, the ongoing expansion of the universe.
The study’s researchers used a year of observations by the Dark Energy Spectroscopic Instrument (DESI) at…
