White holes! and anti-gravitons

White holes are like anti black holes, black holes want matter to come to the event horizon and then suck stuff up but white holes dont want anything to ever cross the horizon, nothing goes out of a black hole and nothing goes in to a white hole, its like blackholes have gravitons and white holes have "anti-gravitons", like super anti-gravity!!, like if a blackhole ate a star in and a white hole is connected to that blackhole and well spits out the star in a non-star form, probably gas. im saying is that the black-hole's singularity is even the reverse singularity of a white hole, time for a picture:

now anti-gravitons are what cause anti-gravity, not the non gravity but the repelling gravity in the white holes another pic:

Or maybe when they die out by radiating for a long long time, then they turn to white holes?

Drake Equation

This is the strangest but simplest equation I have seen, $$N=R^{*}*f_p*n_e*f_l*f_i*f_c*L$$

R* = the average number of star formation per year in our galaxy
fp = the fraction of those stars that have planets
ne = the average number of planets that can potentially support life per star that has planets
fl = the fraction of planets that could support life that actually develop life at some point
fi = the fraction of planets with life that actually go on to develop intelligent life (civilizations)
fc = the fraction of civilizations that develop a technology that releases detectable signs of their existence into space
L = the length of time for which such civilizations release detectable signals into space

the original values were like this:

R* = 1/year (1 stars formed per year, on the average over the life of the galaxy; this was regarded as conservative)
fp = 0.2-0.5 (one fifth to one half of all stars formed will have planets)
ne = 1-5 (stars with planets will have between 1 and 5 planets capable of developing life)
fℓ = 1 (100% of these planets will develop life)
fi = 1 (100% of which will develop intelligent life)
fc = 0.1-0.2 (10-20% of which will be able to communicate)
L = 1000-100,000,000 years (which will last somewhere between 1000 and 100,000,000 years)
So if we put in the values:
first medium:
$$N=1800 civilizations$$

Then small:

Then even smaller:
$$N=0.000005civilizations$$ we are alone

finally larger:

Now for aproximation:
