Dimethylmercury ((CH3)2Hg) is an organomercury compound. This colorless liquid is one of the strongest known neurotoxins. It is described as having a slightly sweet smell, although inhaling enough vapor to detect its odor would be hazardous.
The formation of a star begins with gravitational instability within a molecular cloud, caused by regions of higher density-often triggered by shock-waves from nearby supernovae (massive stellar explosions), the collision of different molecular clouds, or the collision of galaxies (as in a starburst galaxy).
What force do scientists think was responsible for clumping matter together to form the first stars after the Big Bang? gravity, acting upon anisotropies in the distribution of matter caused by quantum fluctuations inflated to cosmological scale by the rapid inflation of the universe. Not directly. Scientists are not sure of the conditions immediately after the Big Bang, which (we believe) created the universe.   gravity. Gravity.
