Because the primordial gas clouds stayed warm, more gravity was needed to overwhelm the gas pressure and make them collapse, so they spawned massive stars.
Because of their warmth, more gravity was needed to overwhelm the higher gas pressure so when a cloud collapsed, it produced massive stars rather than small stars.
In this experiment, the motion which moves center of gravity was needed when the active-caster passed over a step (Figure 15(f - h)).
Using TPFPD correlations for normal gravity to reduced gravity and microgravity may be acceptable for the first approximation, but correlations intended for microgravity and reduced gravity are needed and more experiments are desired to obtain more data with high accuracy.
And the faster the initial velocity, the higher space for gravity separation is needed to get the maximum efficiency.
Although diverse studies have led to the conclusion that a gravity stimulus is needed for plant roots to show waving and skewing, the novel results just published by Paul et al. (2012) reveal that this conclusion is not correct.
Such a theory of quantum gravity, scientists agree, is needed to describe the universe when it was so small and dense that even space and time become fuzzy and discontinuous.
At the same time, the corresponding gravity compensation mechanism is needed for safety.
Mr. McConnell and his thesis adviser, Chung-Pei Ma, led a team of astronomers who used telescopes in Hawaii, Texas and outer space to weigh the black holes in the centers of galaxies by clocking the speeds of stars zooming around them; the faster the stars are going, the more gravity — and thus mass — is needed to keep the stars from flying away.
The goal of tree traversal is to identify for each bucket of particles in the tree the list of nodes and particles whose information is needed for the gravity calculation.
