    M theory Theory
AI Thread Summary
M Theory is a theoretical framework in physics that unifies various string theories, suggesting that fundamental particles are not zero-dimensional points but rather one-dimensional strings. It posits the existence of multiple dimensions beyond the familiar four, which can help explain the fundamental forces of nature. Stephen Hawking's "The Universe in a Nutshell" offers a brief overview of M Theory, particularly in its third chapter. For a more in-depth understanding, works by Brian Greene, such as "The Elegant Universe," and Michio Kaku are recommended. M Theory remains a complex and evolving area of study in theoretical physics.

i overheard someone talking about something called the M theory. They mentioned the string theory too (which i know about), but I have no idea what M theory is. Can someone please inform me?

Hmmmm

Stephen W. Hawking's book "The universe in a Nutshell" talks briefly on the subject, I believe in the... 3rd chapter? Or if you are listening to the CD it is on the second, to the best of my knowledge...

I would quickly suggest Brian Greene, or even Michio Kaku, above Hawking. Try The Elegant Universe (by Greene).

Thread 'Venus and Jupiter Conjunction'

Today at about 4:30 am I saw the conjunction of Venus and Jupiter, where they were about the width of the full moon, or one half degree apart. Did anyone else see it? Edit: The moon is 2,200 miles in diameter and at a distance of 240,000 miles. Thereby it subtends an angle in radians of 2,200/240,000=.01 (approximately). With pi radians being 180 degrees, one radian is 57.3 degrees, so that .01 radians is about .50 degrees (angle subtended by the moon). (.57 to be more exact, but with...
