Cosmology : And the Earth doesn't fall

Post #1by jogad » 28.03.2009, 12:47

Hi,

This is the reason why the Earth doesn't fall in the Universe.
It is hung in the sky by a magnet!

Did you know that?

The implications for magnetic reversals are huge.

:D

Right... Gravitation is self-conjugate and correspondingly, masses ALWAYS attract gravitationally. No signs of repelling anti-gravitation anywhere ;-) .

This is unlike magnetic forces where equal magnetic polarity repels while unequal one attracts.

So what is the so-called Dark Force then? Just curious.

Bob,

very good question that has no answer for now.

Dark energy and the associated dark force acts indeed somewhat like repelling anti-gravitation: on the one hand, we expect the expansion of the Universe to slow down by means of the cumulative gravitational attraction of all matter, on the other hand we see it expand even faster... The main conceptional problem is actually not the dark force itself, but rather the lacking scale that could naturally explain its strength...

Give that thing a pole-to-pole spin and see if it generates current. :lol:

Well that's the answer to all of mankind's power problems... we're spinning on the wrong axis! :lol:
