XHTML 2.0: The W3C is considering replacing
<del> in XHTML 2.0 with a common
edit attribute, which can also mark changed and moved content. The
edit attribute is better designed to fulfill the needs of revision tracking than
<del>, which seem like ill‐considered semantic replacements for the deprecated
That’s one small step for
Mana man, one giant leap for mankind.
Just remember that you’re standing on a planet that’s evolving,
9001,000 miles an hour,
It’s orbiting at
1918 miles a second, so it’s reckoned,
a sun that is the source of all our power.
The sun and you and me, and all the stars that we can see,
at a13 million miles a day,
In an outer spiral arm, at
40,000half a million miles an hour,
of the galaxy we call the Milky Way.
Our galaxy itself contains
100400 billion stars,
it’s 100,000 light-years side-to-side,
It bulges in the middle,
1615,000 light-years thick,
but out by us it’s just 3,000 light-years wide.
We’re 30,000 light-years from galactic central point,
we go round every
200one quarter million years,
And our galaxy is only one of millions of billions
in this amazing and expanding universe.
The universe itself keeps on expanding and expanding,
in all of the directions it can whiz,
As fast as it can go, the speed of light you know,
12 million miles a minuteone eight six thousand miles a second, and that’s the fastest speed there is.
So remember, when you’re feeling very small and insecure,
how amazingly unlikely is your birth,
And pray that there’s intelligent life somewhere up in space,
’cause there’s bugger all down here on Earth.
