Then, the process of becoming pregnant takes several days -- the fertilized egg (now called a blastocyst) has only just begun its long journey. Once the egg is fertilized, it now has to travel all the way up into the uterus for implantation to take place. As the blastocyst makes this journey, it will continue to grow in size. At the same time, its cells will continue to divide and reproduce.
gravitational field - a field of force surrounding a body of finite mass. field of force, force field, field - the space around a radiating body within which its electromagnetic oscillations can exert force on another similar body not in contact with it.
Thus, a gravitational field is used to explain gravitational phenomena, and is measured in newtons per kilogram (N/kg). gravitational field can be defined using Newton's law of universal gravitation. Determined in this way, the gravitational field g around a single particle of mass M is a vector field consisting at every point of a vector pointing directly towards the particle.
