The shape of the universe

The shape of the universe

The universe could be positively curved, like a sphere. … In a flat universe, Euclidean geometry applies at the very largest scales. This means parallel lines will never meet, and the internal angles of a triangle always add up to exactly 180 degrees—just like you’re used to.

Is there an edge to the universe?

Ballooning universe. But how can the universe be expanding if there is no end or edge to it? … That is, the concentration of matter in the universe is decreasing as the universe expands, she said. That’s because galaxies aren’t moving away from each other through space — it’s space itself that is getting bigger.

Is there an end to space?

Whether space ever ends is a hard question. There is a limit to the space that we can see, because if there is stuff beyond 15 – 20 billion light years (the age of the Universe) the light from there hasn’t reached us yet. So we don’t know.

What is at the center of the universe?

FYI: Where Is The Center of the Universe? First, it’s important to know that the big bang wasn’t an explosion of matter into empty space—it was the rapid expansion of space itself. This means that every single point in the universe appears to be at the center. Think of the universe as an empty balloon with dots on it.
