Astronomy Without A Telescope – Is Time Real?

[Image: CMB_Timeline752.jpg]
^klik^

The way that we deal with time is central to a major current schism in physics. Under classic
Newtonian physics and also quantum mechanics – time is absolute, a universal metronome
allowing you determine whether events occur simultaneously or in sequence. Under Einstein's
physics, time is not absolute – simultaneity and sequence depend on who's looking. For Einstein,
the speed of light (in a vacuum) is constant and time changes in whatever way is required to
keep the speed of light constant from all frames of reference.

An Ocean of Plastic...In Birds' Guts: Chris Jordan's work attempts to place the impact of consumerism in perspective. For his latest project, he traveled to the Midway Islands, near the heart of the Pacific Trash Gyre, to photograph the decomposed bodies of chicks that have been fed plastic litter by confused parents.

Undecided
The images of the ex-baby albatrosses are heartbreaking Sad

Lewis Thomas says (...and I'm paraphrasing...) Planet earth is 4600 million years old.

If we condense this inconceivable time span into an understandable concept, we can
think of the Earth's age as being just 46 years old. For the first seven years nothing is
known, and only scattered information about the middle span.

We know at age 42 Earth began to flower. Dinosaurs and reptiles did not appear until
one year ago (when the planet was 45) Mammals arrived 8 months ago. In the middle
of last week, human like apes evolved into ape like humans. At the weekend the last
ice age enveloped the earth.

Humans have been around for 4 hours. The industrial revolution began 1 minute ago.

During those sixty seconds of geological time we have caused the extinction of 500,000
species, ransacked the planet for fossil fuels, destroyed ecosystems, caused the planet
to warm artificially and grown our population out of control.

RE: EDUCATIONAL Tools
Again, I (we) can't thank you enough for starting this thread.

Should it be a sticky? Opinions, anyone?

GREAT STUFF! but I thought a tad pricey...
...but the samples were so fascinating Smile

Upon closer observation
I came to realize that the PRODUCT Was Actually


VIRTUAL INSTRUMENT PROGRAMS Cool
