ถึงคุณ วาทิต (จขกท.) ครับ
ข้ออนุญาตแย้งเรื่องที่คุณบอวกว่าเอกภพมีมีและมีขอบเขตนะครับ
อ้างอิงข้อความจาก Seed & Backman's Foundation of Astronomy edition 11th ครับ (ไม่กล้าแปลเพราะเกรงว่าผมจะถอดความได้ไม่ดี)
In your daily life you are accustomed to boundaries. Rooms have walls, athletic fields have boundary lines, countries have borders, oceans have shores. It is natural to think of the universe also as having an edge, but that idea can’t be right.
If the universe had an edge, imagine going to that edge. What would you find there: A wall of some type? A great empty space? Nothing? Even a child can ask: If there is an edge to the universe, what’s beyond it? A true edge would have to be more han just an end of the distribution of matter. It would have to be an end of space itself. But, then, what would happen if you tried to reach past, or move past, that edge?
An edge to the universe violates common sense, and modern observations (which you will study later in this chapter) indicate that the universe could be infinite and would therefore have no edge. Perhaps even more important, if the universe has no edge, then it cannot have a center. You find the centers of things—pizzas, football fields, oceans, galaxies—by referring to their edges. If the universe has no edge, then it cannot have a center.
