In 1882, Felix Klein imagined sewing two Möebius loops together to create a single-sided bottle with no boundary. It’s inside is it’s outside, so it contains itself.

Klein Steins?

Why Is This Man Smiling?

What Is Man’s Place

In The Universe?

Page 8: Klein Bottles

Ancient Man:

The Earth is the center of the Universe. We know

this because everything in the sky turns around the

Earth. It’s obvious man!!

Page 9: Klein Bottles

Copernicus (15??):

The Sun is the center of the Universe. I know this because

the orbital calculations come out with less overall error this way. The orbits are perfect circles.

Page 10: Klein Bottles

Kepler (16??):

The Sun sits at one of the focal points of each planet’s elliptical orbit. I know this because I stole Tycho Brahe’s data and there’s

simply less error in the calculations if you assume elliptical orbits.

Page 11: Klein Bottles

1700’s to early 1900’s:

The Sun is just one of:TENS OF THOUSANDS

TENS OF MILLIONSHUNDREDS OF MILLIONS

HUNDREDS OF BILLIONS of other stars in the Universe.

Page 12: Klein Bottles

1920-ish:

“Hey, those fuzzy spiral blobs in the sky are other galaxies! And

the Milky Way is just one galaxy out of HUNDREDS OF BILLIONS of others!!”

Page 13: Klein Bottles

Does this mean we are on an insignificant planet orbiting an average star which is a member

of an ordinary galaxy?

Is there nothing special about us?

Page 14: Klein Bottles

Edwin Hubble (19??):

Hey – all those other galaxies are running away from us! Maybe

we’re special after all?

Page 15: Klein Bottles

Nope – it turns out that in an expanding universe, everyone sees it as if all the other stars are running away from them.

Page 16: Klein Bottles

1950’s:

Hey – none of these galaxies seem like they have enough visible mass to explain their

rotation speeds!

Page 17: Klein Bottles

1970’s:

Hey – none of these galaxy clusters seem to have enough

visible mass to explain the motions of the galaxies inside

them!

Page 18: Klein Bottles

1980’s:

No problem. That just means that there’s “more than meets the eye”

when it comes to Astronomy.

We’ll just call that missing stuff “dark matter”, and try to look for

different kinds of it.

Page 19: Klein Bottles

1990’s:

Y’know what? We’ve found lots and lots of dark matter, but it

STILL doesn’t add up to enough to explain anything. It’s as if 70% to 90% of the Universe’s mass is

hidden. What’s this mean?

Page 20: Klein Bottles

The ultimate insult:

We aren’t even made of the most common type of matter in the

universe.

What could be more humbling than that?

Page 21: Klein Bottles

Well . . . .

If the current thinking is correct, then we might be aware of only 3 of the 10 or 11 dimensions that

exist.

Page 22: Klein Bottles

Or, worse yet?

We might be living in just one universe out of an infinite

number of universes that were created all together in the 11-

dimensional Big Bang that started everything.

Page 23: Klein Bottles

Is all that really so bad though?
