Well once moon rocks run out, we have no moon and that would certainly have an effect on earth.

Oh I would also like the moon turned around so we see the other side instead.

33: Build a bigger black hole to reproduce Moon's gravity. Problem solved!

32: Reconstitute CERN to make micro black holes. Micro black holes are versatile -- use them peacefully as long-term energy sources once the Jupiter Sun runs out. And use them as leverage against terrorists who refuse to pay fines once the Moon rocks run out.


Good idea! I like it.

The Moon is very big, and it doesn't take a very large stone to do damage if it falls all the way from space. I don't think the Moon running out is much of a danger. But if it does happen, we could make a new Moon out of Mars.

I like the idea of terraforming the sun.

How will a black hole make energy? Even earth mass ones would just disintegrate due to hawking radiation.

An Earth mass black hole would never disintegrate under current conditions. The mass it'd lose due to Hawking radiation would be millions of times smaller than the mass it gains from cosmic background radiation alone.

steeljaw354, this process take billions of years and even more.
The rate that this happens depends on the mass. For stellar mass black holes, it might take 10^67 years to evaporate completely.
For the big supermassive ones at the cores of galaxies, you’re looking at 10^100

Where P is the energy outflow, hbar is the reduced Planck constant, c is the speed of light, an G is the gravitational constant.
the power in the Hawking radiation from a solar mass black hole turns out to be a minuscule 9 × 10−^29 watts

(I HAVE NO IDEA HOW Watsisname TURN THE FORMULAS INTO WHITE COLOR)
The time that the black hole takes to dissipate is:

Where M0 is the mass of the black hole.
For a black hole of one solar mass = 1.98892 × 10^30 kg, we get an evaporation time of 2.098 × 10^67 years—much longer than the current age of the universe at 13.799 ± 0.021 x 10^9 years.

Well where would you put the black holes?

/dev/null is the location of mine.

I write them in LaTeX and then invert the color in GIMP for posting on the black forum background. Fixed the images for ya, too. smile

Reform the Austro-Hungarian Empire but under democracy.


Thank you sir, I get to have my Empire back

(I know, first page stuff, I'm behind)





Living among the stars, I find my way. I grow in strength through knowledge of the space I occupy, until I become the ruler of my own interstellar empire of sorts. Though The world was made for the day, I was made for the night, and thus, the universe itself is within my destiny.

How would you build these black holes? Why would you terraform the sun instead of doing a dyson sphere? With artificial gravity somehow, a dyson sphere is hundreds of times larger than the sun.

steeljaw354, we can always do dyson sphere around our new jupiter sun if needed.
we wont need its light because of our giant lamp orbiting the earth!
we can also build a giant lamp around our terraformed sun too!
also! animals have sleep cyrcles! just think about the possibilty of a giant lamp!
we can always turn the off\on bottoms as we wish. if we want night or day!

We wouldn't have to turn off the lamp, it would just orbit, how would you have 1 lamp light up 1 half of the sun while it would take so long to orbit? Well you could do this instead.
