Today’s trippy thought…..

Where does the universe end? Or is it spherical? Or is it infinite?

And if it’s infinite that means that there’s an infinite amount of mays organisms can multiply……or even duplicate. Have we been duplicated? Is there a parallel universe where IU didn’t hire MIke Davis and sent us on a different path?

Hmmmmm

I think its silly to think we are the only form of life in the universe. Fortunately, I'm still pretty young, so I think I will be alive when that day comes. 

Who knows, they may already be here.

It's common for people living on the planet Gorglopia to have 9 wives.  Just saying....

You have to be a workaholic.  9 wives sounds exhausting.  Unless you met 8 in Vegas.

...and how many "Class M" planets are out there?

Asteroids, Brah: 

Jupiter has been called the vacuum cleaner of the solar system because its gravity sucks in asteroids and comets, protecting us from those objects. But it's not all good: Jupiter's gravity can also nudge an object onto an orbital collision course with Earth.

The good news is that the earlier we detect them, the easier it is to devise a plan to nudge them off course. And we don't want to use the 'Armagedon' method of blowing up an Asteroid because it will create a shower of smaller rocks, that will do just as much damage. The trick is nudging. 

By the numbers (size to damage ratio)......

- most meteors are smaller than a car and burn up in the atmosphere as harmless meteors.

- Any larger than that, and things start getting risky. Some detonate into airbursts high above the ground. These explosions create shockwaves strong enough to break windows. They can also emit enough light energy to cause a sunburn.

- A house-sized meteorite can explode in Earth's atmosphere with a force greater than the nuclear weapon the US dropped on Hiroshima in 1945. Such a space rock could flatten most buildings within 1.5 miles of ground zero.

- An asteroid the size of a 20-story building is bad news. With the right composition, speed, and angle of attack, a rock this size might leave a wake of destruction the size of central Paris.

- One roughly the size of a football field could obliterate New York, causing a 7.7-magnitude earthquake that might be felt than 1,000 miles away.

- An asteroid more than half a mile wide would start to have global implications. It could destroy an area the size of the US state of Virginia. Dust tossed up from the impact would block the sun and lead to rapid changes in climates across Earth.

- A Mount-Everest-size space rock would vaporize everything around its impact site for miles. The resulting crater would stretch more than 100 miles wide.  The aftermath that follows would kill most life on Earth. This is similar in size to the space rock that killed the dinosaurs.

- A London-sized asteroid would be more than just a major extinction-level event. Its impact would slow down Earth's rotation enough to make its day last almost half a second longer.

- The largest known asteroid, Ceres, is about the size of Texas.
