Do we really need the sun?

i think i'd be pretty pissed if i were to wake up and find that its 3 degees Kelvin outside. i also think i'd be pretty pissed having my planet hurtling across the universe at 67,000 miles per hour because the thing it was orbiting around disapeared,

The resident energy expert here (laughingly after reading this thread over my shoulder) tells me that if we could (theoretically) produce the equivalent energy output of the sun here on Earth that every single resource (fossil, nuclear, chemical) would be consumed entirely in less than a week. :shocked:

yeah, the sun puts so much energy on the surface of the earth that is would be equal to us burning all our fossil fuel in one day, idr where I heard that before.

Assuming the sun was to just "go out" and not die in normal fashion, in which case the Earth would be roasted by a rapidly expanding sun before we even have to worry about being cold, and also assuming humans could survive, the earth would eventually cool to about 2.7 Kelvin (or about 270 degrees below zero). Being just a few degrees above absolute zero nothing would survive. The entire plant would freeze to the core. Our atmosphere would be gone. We would be unprotected from high amounts of solar radiation that would assail our plant. Of course oxygen would be a thing of the past. So while we can create "artificial sunlight" quite easily life would end without the real thing.
But if you insist it would be great without the sun just take a trip to northern Siberia during a six month night and let us know how it goes.

"We would be unprotected from high amounts of solar radiation that would assail our plant." really? without the sun we'd have solar radiation?

The radiation would be from lack of an atmosphere which would be destroyed by the massive temperature fluctuation.

I think you're missing my point that SOLAR radiation comes from the SUN, so if the SUN is GONE there would be no SOLAR radiation.... 😛
 
what the hell???

how could ANYONE even ask this question.


I hate getting wet in the rain...cant we just get RID of all the water...Soda is better tasting anyway.

 
JLGatsby doesn't need the sun because his Pathfinder can drive through cold fusion like it's NOTHING. NOTHING. he once drove through 25 feet of cold fusion, when his car wouldn't have even been able to move. he would have had to just park it back in the garage. luckily his pathfinder doesn't need the hot fusion. it can drive on teh cold.
