Shape of the universe
The shape of the universe is the local and global geometry of the Universe, in terms of both curvature and topology (though, strictly speaking, the concept goes beyond both). The shape of the universe is related to general relativity which describes how spacetime is curved and bent by mass and energy.
There is a distinction between the observable universe and the global universe. The observable universe consists of the part of the universe that can, in principle, be observed due to the finite speed of light and the age of the universe. The observable universe is understood as a sphere around the Earth extending 93 billion light years (8.8 *1026 meters) and would be similar at any observing point (assuming the universe is indeed isotropic , as it appears to be from our vantage point).
According to the book Our Mathematical Universe, the shape of the global universe can be explained with three categories:
Edge of the Universe (song)
"Edge of the Universe" is a rock song by the Bee Gees, Written by Barry, Robin and Maurice Gibb from the album Main Course released in 1975, and also released as a B-side of "Nights on Broadway".
Recording
In 1975, the Bee Gees moved their operations to Miami Beach, Florida at the suggestion of Eric Clapton following his comeback album 461 Ocean Boulevard the year before. The group recorded an album with famed R&B producer Arif Mardin called Mr. Natural in 1974 with little commercial success. The album did, however, turn the Gibbs towards a new sound compared to the kind of music the brothers were producing in the early 70's. This new flavored sound carried over on to their next album, 1975's Main Course, also produced by Arif Mardin.
The Bee Gees had formed the nucleus of their band in early 1975 with Blue Weaver on keyboards, Alan Kendall on lead guitar and Dennis Bryon on drums. Also part of the Bee Gees to mid to late 70's sound was The Boneroo Horns brought to Miami in 1973 by Dr. John. Recording for "Edge of the Universe" took place on a 30 January, the same day as "Jive Talkin'", "Songbird", "Fanny (Be Tender with My Love)" and "All This Making Love".
Edge of the Universe
Just my dog and I
at the edge of the universe.
Well, I didn't wanna bring her
and I know it'll make her worse.
Now I look out on forever
and it must be nice down there.
And they call me Shenandora in the air.
Well, I'm ten feet tall,
but I'm only three feet wide.
And I live inside an ocean that flows
on the other side.
If I came back down tomorrow,
would it all be far too soon?
And it looks like it's gonna be a lovely afternoon.
I thought that I was going home,
and all the way I kept on prayin'.
I couldn't stop to turn around;
well, here I am and here I'm stayin'.
It's been my longest journey
and I've come through the black of night.
I was tired and hungry
when I saw your distant light.
Well, I know this may sound crazy,
but I'm sure I got here first.
I'm just me, Shenandora,
at the edge of the universe.
I thought that I was going home,
and all the way I kept on prayin'.
I couldn't stop to turn around;
well, here I am and here I'm stayin'.
Just my dog and I
at the edge of the universe.
Well, I didn't wanna bring her
and I know it'll make her worse.
Now I look out on forever
and it must be nice down there.
And they call me Shenandora in the air.
