original question: what Galactic interaction type is Galactic interaction with Galactic interactions of [Present]?
answer: galactic collision
answer type: Galactic interaction type.
auxiliary information: The present is the time that is associated with the events perceived directly and in the first time, not as a recollection or a speculation. It is a period of time between the past and the future, and can vary in meaning from being an instant to a day or longer. In radiocarbon dating, the "present" is defined as AD 1950. It is sometimes represented as a hyperplane in space-time, typically called "now", although modern physics demonstrates that such a hyperplane cannot be defined uniquely for observers in relative motion. The present may also be viewed as a duration.
The Galactic interaction of the [Present] with another Galactic interaction is of what Galactic interaction type?
