Presently, dark energy — a mysterious substance that seems to be associated with the vacuum of space itself — is pushing the universe outwards more
strongly than gravity pulls in, causing the universe to not only expand but to do so faster and faster.
«Holger has ruled out chameleons that interact with normal matter more
strongly than gravity, but he is now pushing his experiment into areas where chameleons interact on the same scale as gravity, where they are more likely to exist,» Khoury, co-author of the study published Friday in the journal Science, said in the statement.
Not exact matches
They form when a large galaxy's
gravity pulls one edge of a nearby satellite galaxy more
strongly than the other edge, unraveling the galaxy and leaving stars behind.
According to Bertolami, a variable gravitational constant readily explains why galaxies in clusters are being whirled around so rapidly: the individual galaxies attract each other more
strongly than predicted by Newtonian
gravity.
In the September Physical Review D, he explains that in certain circumstances Hoava's graviton fluctuates as it interacts with normal matter, making
gravity pull a bit more
strongly than expected in general relativity.
Objects orbiting one of the stars in a binary system will be
strongly affected by the
gravity of the other and so can be more easily ejected from the system
than if it had just one star.
I
strongly believe in the law of
gravity, but I do not tell anyone they «can not fly» because the law of
gravity says (with a much stronger consensus
than climate science) that every thing that goes up WILL come back down almost always safely (unless we launch it with enough velocity to escape Earth's
gravity).
