For all of you astronomy lovers, what if?

Interesting concept. I guess we would be one part of a binary planetary system where we would be dragged along the orbit of the larger planet, locked in a continuous dance around each other. Sunrise and sunsets would be less regular due to interference caused by the gravitational pull between the twinned planets. I don't even want to think about what would happen to the seasons and plant life.

I'm rather glad that Earth is the Goldilocks planet.

Yes, my instant thought was, what would happen to our seasons, our days, our nights, what sorts of other related conditions would be apparent... would the atmosphere be more radioactive, would storms (thunder, lightning, rain, snow, wind, etc,) be more severe, what would our oxygen and carbon monoxide levels be like, and of course, what about our plants, trees, water, wildlife.

The scene of Saturn with it's rings is so incredibly beautiful. Such a shame we don't get to enjoy a half dozen planets or more as our moon throughout the year, wouldn't that be a treat.
 
If Saturn or Jupiter were in our Moon's place, the Gravitational pull would doom us. In what amount of time? That question is reserved for say, an Astrophysicist.

Remember David Scott's experiment on the moon confirming Galileo's theory of gravitation? He dropped a hammer and a feather at the same time. They both hit at the same time.
 
What if a tablespoonful of a neutron star was brought to Earth?

"A tablespoon of the Sun, depending on where you scoop, would weigh about 5 pounds (2 kilograms) — the weight of an old laptop. A tablespoon of neutron star weighs more than 1 billion tons (900 billion kg) — the weight of Mount Everest. So while you could lift a spoonful of Sun, you can’t lift a spoonful of neutron star".

Wow! Totally awesome entries, Ohio and Meanderer!

Some serious food for thought. :love:
