In the new study, an international team of researchers explored another way to measure the Hubble constant. This strategy depends on the definition of gravity, according to Albert Einstein's ...

Once again, physicists have confirmed one of Albert Einstein's core ideas about gravity — this time with the help of a neutron star flashing across space. ... In constant free fall, ...

Therefore, Einstein's gravity cannot be the ultimate theory of gravity. ... Here, Λ stands for either Einstein's famous cosmological constant or a mysterious dark energy with similar properties.

The accelerating expansion of the Universe, first observed in 1998, remains one of the most profound mysteries in modern physics. It challenges long-standing assumptions about the cosmos and has ...

Albert Einstein’s theory of general relativity has been remarkably successful in describing the gravity of stars and planets, but it doesn’t seem to apply perfectly on all scales.

Einstein's self-proclaimed "biggest blunder" -- his postulation of a cosmological constant (a force that opposes gravity and keeps the universe from collapsing) -- may not be such a blunder after ...

Einstein’s theory of gravity — general relativity — has been very successful for more than a century. However, it has theoretical shortcomings. This is not surprising: the theory predicts its own ...

Einstein's equations also describe how gravity can bend light. Public Domain Fields of gravity around objects warp light waves as they pass through, like a huge cluster of galaxies.

Through an effect called gravitational lensing, first predicted by Albert Einstein, a distant galaxy named MRG-M0138 ... Researchers remeasure gravitational constant.

Einstein's explanation is the only one that works. Newsletters Games Share a News Tip. ... and the gravitational constant of the Universe. So how, then, do massless particles, like photons, ...

Through extremely high precision measurements of a pulsar orbiting a white dwarf star, astronomers have found that the gravitational constant, which dictates the force of gravity, is "reassuringly ...
