The events which have occurred earlier than now are finite in number. Consider:
• …the Universe is not at max entropy• …an actual infinity cannot be formed by adding• …an actual infinity cannot be instantiated• …the Hot Big Bang model is true
The Universe began to exist (or has a “beginning of its existence”). Consider:
• …the number of past events are finite in number• …the Big Bang model is true
The events which have occurred earlier than now are infinite in number. This is relevant because if the Universe is past-infinite, then its series of past events does not terminate in a first event.
