Can someone explain in some easy way.

For example, I think that everyone gets that the universe is expanding because space itself is expanding. No one quite knows how space itself can expand but ok so space is expanding.

Further, gravity bends space so light curves when it goes around dense stars and even black holes.

So can someone connect those two observations with the math and observations of this article?

Just tell me what is on the other side of nothing. Does nothing never end?

But only God knows, because he’s already there.

It's like something out of a Robert Frost poem.

I don’t know that “space” itself is expanding, but everything inside of it is.
I’m hoping that the Webb telescope will show us what’s really “out there” in the manner that the two radio astronomers discovered the cosmic background radiation, only in a visual sense.
I have a difficult time when I’m confronted with higher forms of physics.
E=mc squared I get. I have a hard time with quantum physics and the like.
Not that I don’t believe in it, I get a headache trying to understand it.

I really don’t give a flying fig. I know how far away the grocery store, gym, and my daughter’s house are. The rest of space can expand or shrink all it wants. BFD.

How’s that for a scientific explanation?

From what I read there, it seems that previous assumptions of the relationships of particles (presumed to be on a “flat space”) were giving wonky answers when trying to figure how they moved. By using a different notation describing a curved space then observations “worked out” better.

But I’m probably seriously misguided ;-)

My dad, long gone now, told me as a young boy looking at stars in the cold clear central NY winter, probably around 1973 or so, when I asked him how far were the stars? His response was classic. “Son, they are just always a bit farther than you can reach”.

He was right. Most of what we know of space and distance and time are turning out to be rather simplistic and archaic, even though only a entity old....

This sounds like word speak like AOC would use except too big of words.

Think of space as a 3d field- not empty.

The field is made of many layers of spandex, one on top of the other.

2 bb’s in the spandex are in same layers ( z) and 10 inches apart on the xy plane.

Now think of something (or many things) that pull the spandex, not the bb - between the bb’s- Creating a mound.

Now the bb are closer or further apart depending on whether they travel on the same spandex layer (further), or through spandex layers (closer).

This is analogous to changes in field density of space.

Or maybe not…
