The Earth. Christianity. They go together.

EARTH IS JUST ONE PLANET OUT OF 100 BILLION — From Astrobiology.com: 100 Billion Planets May Populate the Galaxy. Not only could there be 1011 planets in the Milky Way galaxy alone, there are an estimated 1021 stars in the universe. This seems to make Earth, and the humans who inhabit it, seem rather insignificant. But consider this quote from John Piper:

Sometimes people stumble over this vastness in relation to the apparent insignificance of man. It does seem to make us infinitesimally small. But the meaning of this magnitude is not mainly about us. It’s about God… The reason for ‘wasting’ so much space on a universe to house a speck of humanity is to make a point about our maker, not us.” –John Piper, Seeing and Savoring Jesus Christ.

YOU ARE JUST ONE DOT OUT OF 341,817,095 — An online map showing over 340 million dots, one for each person in the 2010 United States and 2011 Canadian censuses.

Zoom in and individual dots can be resolved. My dot is somewhere in the middle of here:

Does being just one dot out of 340,000,000 (or one dot out of roughly 7,000,000,000 on Earth today) make the individual dots insignificant? Not at all. The same God who created the universe with its 1021 stars, or the galaxy with its 100 billion planets, has this to say about you as an individual:

For God so loved the world,that he gave his only Son, that whoever believes in him should not perish but have eternal life.” — John 3:16 ESV

DANGEROUS SCIENCE?7 scientists killed by their experiments — Marie Curie, and six others.

COLDER THAN COLD? — According to one report (Science gets colder than absolute zero), temperatures colder than absolute zero are possible.

Absolute zero is often thought to be the coldest temperature possible. But now researchers show they can achieve even lower temperatures for a strange realm of “negative temperatures.”

Oddly, another way to look at these negative temperatures is to consider them hotter than infinity, researchers added.

This unusual advance could lead to new engines that could technically be more than 100 percent efficient, and shed light on mysteries such as dark energy, the mysterious substance that is apparently pulling our universe apart.

——————————————

Temperature is linked with pressure — the hotter something is, the more it expands outward, and the colder something is, the more it contracts inward. To make sure this gas had a negative temperature, the researchers had to give it a negative pressure as well, tinkering with the interactions between atoms until they attracted each other more than they repelled each other.

Or perhaps this is in the same category as last year’s report of particles going faster than the speed of light. Interesting, but not true.

Grace and Peace
