SCARY THOUGHT YOU SHOULD HAVE WHILE LYING IN YOUR BED:
Our Solar System's Journey Through the Milky Way -A Galaxy Classic:
Is there a genocidal countdown built into the motion of our solar system?
Recent work at Cardiff University suggests that
our system's orbit through the Milky Way encounters
regular speedbumps - and by "speedbumps"
we mean "potentially extinction-causing asteroids"......

NEW PVAF FEATURE
 TO SHARE VERY BASIC KNOWLEDGE ABOUT
YOURSELF AND THE UNIVERSE YOU LIVE IN

A majority of us as humans live automated life. The automated life is through two life processes:

1.  Our body is run by what we call Nature so far we nourish it with a few basics such as food, shelter and satisfying auto-generated self needs by body powered human actions .....

2.  Our food and shelter and other auto-generated needs are automatically fed by the social, political, economical systems at house, community to national and international levels.

This new PVAF feature, has been initiated and is being moderated by PVAF's Chair of Web & Education Development, Champak Mistry, B.E. (civil), P. Eng who lives and practices municipal infrastructure engineering and project management of community developments through his own business in Edmonton, Alberta, Canada.



Through this new feature, PVAF will be publishing basic KNOWLEDGE with its TRUTH and REALITY about yourself and your world....

And this presentation the on this web site will make you wonder why you never bothered to search or have this KNOWLEDGE with its TRUTH and REALITY....and prayfully will awaken and inspire you to search and find the answer to the age-old quest for the meaning of yourself in your world.....  

And this quest through awakening and inspiration about yourself and your world is hoped, as a TRUTH, to MAKE YOUR TOMORROW HAPPIER THAN TODAY/strong>......simply because in all belief and cultures of all civilizations known to  have existed on this planet Earth to date has known TRUTH and REALITY the following cliché and/or axiom:

KNOWLEDGE SHALL SET YOU FREE FROM ALL YOUR SUFFERING....
 
BUT MAY NOT BRING HAPPINESS IF
THE
KNOWLEDGE IS NOT USED WITH
ITS
TRUTH
AND IN CONTEXT WITH
THE
REALITY OF HUMAN EXISTENCE ON
 
THIS ROTATING PLANET EARTH WHICH EXISTS AND REVOLVES
IN THIS SOLAR SYSTEM WHICH IN TURN
EXISTS AND ROTATES IN THE MILKY WAY GALAXY
WHICH IN TURN HAS MOTION IN OUR UNIVERSE.....
 
THE MOTION AND THE UNIVERSE
ABOUT WHICH WE HARDLY KNOW MUCH...

Our today's first ever feature knowledge sharing is something about most of us have rarely thought about or even some of us know the basic numbers in this knowledge sharing but it is a REALITY and TRUTH about of very daily existence.....As Confucius said (paraphrased) : strong>A BUTTERFLY FLUTTERING ITS WINGS ON THIS PLANET EARTH COULD AFFECT ANYWHERE IN THIS UNIVERSE.....

Today's question is very simply awakening: How fast you are moving while lying in bed a sleep?

Please click on the next line to awaken yourself to a lot of TRUTH of the dynamic time-space-motion REALITY you are sleeping in....or rather you are continually travelling in space and places where either you have travelled before or where you have never been there before......and it is all on the 2 auto-controls mentioned above in the first left-hand column.......



 

Considering the motion of
the Earth, the solar system, and the galaxy,
how fast am I moving while lying in bed asleep?
(FROM WEBSITE: CUROUS ABOUT ASTRONOMY...ASK AN ASTRONOMER)


Figuring in the Earth's spin, its rotation around the sun, the suns rotation around the galaxy, and the galaxy's rotation around the center of the universe (wherever that is) how fast am I moving even while lying in bed asleep?

Well, it depends. Your latitude on Earth--that is, how close you are to the equator--and the time of year make a difference. I'll explain why. Your motion is made up of four pieces: the rotation of the Earth on its axis, the motion of the Earth around the Sun, the Sun's orbit about the center of the galaxy, and the motion of the whole galaxy.

Now, at the equator, the Earth's rotation translates into a speed of about 0.5 km/s (you can find these numbers here). But if you are at the North or South pole, the speed due to rotation is zero! If this doesn't make sense immediately, imagine a person standing on the equator. Though she's standing still, she actually covers a lot of distance as the Earth rotates--in one day, the Earth's rotation carries her a distance equal to the circumference of the Earth, about 24,000 miles. Now imaging someone standing at the North pole. The Earth's rotation doesn't carry him anywhere at all--so his velocity is zero. I assume you live somewhere in between the equator and the poles, but we'll use the speed at the equator to make things simpler.

Next, the Earth moves at about 30 km/s in its orbit around the Sun. This is a lot faster than the 0.5 km/s caused by the Earth's rotation on its axis! In fact, because it is so small compared to the other velocities we're working with, it's reasonable to ignore that 0.5 km/s for the rest of the calculation.

Now, the whole solar system is moving around the center of the galaxy at about 230 km/s. For half of the year, the Earth's motion around the sun is in the same direction as this motion about the center of the galaxy, but for the other half, it is in the opposite direction--that is, sometimes we're moving "upstream," and sometimes we're moving "downstream." When the motions are exactly aligned, the velocities combine to 230 km/s + 30 km/s = 260 km/s When they are opposite, though, we have to subtract the velocities: 230 km/s - 30 km/s = 200 km/s

So that sums up the first three kinds of motion. Finally, there is the motion of the whole galaxy, which can actually be broken down further into the motion of the galaxy in the Local Group--a cluster of about 20 galaxies--and the motion of the Local Group in an even bigger cluster, the Local Supercluster. These velocities are about 40 km/s and about 600 km/s.

Adding everything up, we get:

30 km/s + 230 km/s + 40 km/s + 600 km/s = 900 km/s

So, you're moving pretty fast as you lie in bed!
