is this huge lottery actually another stage in natural selection, will the strongest and fastest sperm have the best chance of reaching the egg (ignoring the variance of the race!) and carry these characteristics into me. at a guess I am guessing what i just said is a load of crap but its...

thats for all the replys, all extremely interesting. a couple more questions if you don't mind. What if a different sperm had reached the egg, was that my only chance of life gone? When a man ejaculates, are they essentialling ending 40 million to 600 million potential lives [wikipedia...

But why am I me? What were the chances of me being born

thanks for answering some of my questions :biggrin: can anyone help to answer my other questions in my post?

oh and another thing, ants, spiders tiny species like that, was I more likely to end up as one of these? I am guessing so as there appears to be nothing special about humans.

Why am I this brain and not another brain, I heard that if a sample of DNA was taken of me and I could be brought back to life in 1000 years it would be a copy of me but I wouldn't actually be me so to speak, Is this correct? Why am I not in control of someone elses body. To quote Richard...

Why do some photos have black squares cut out of them from hubble, like this: http://nssdc.gsfc.nasa.gov/image/astro/hst_antennae_9734a1.jpg

Could u not shoot waves with higher frequencies than visible light at it as a kind of radar (gamma rays?) to detect a shape in a bit more detail.

i thought i heard on a scientific documentary that in the future the sun could be used to accelerate a probe to 1/3 of the speed of light or something ridiculous, not possible ?

I read a recently launched spacecraft is going to pluto and is swinging around Jupiter to help it speed up. I don't understand much about physics but surely the planets gravity will give as much kinetic energy as it takes away, once the craft is moving away from the planet. How can it...

im absolutely terrified of dying, i think most people are. just the idea of never thinking another thought scares me, I am not a religious person but i hope there is something after :biggrin:

how does something that has no size have a finite mass ?

I have an interest in physics, I have not studied it at any high levels (as u will soon find out :smile: ), i just like to read and think about it, but I have a question, please don't blind me with maths! If a singularity at a black hole has infinity density, I'm guessing this means it has...
