Yes I know only one sperm can fertilize an egg, but hey there are exceptions for everything, and with billions of people in the world, conception takes place very often, so If two sperm managed to fertilize an egg, what would happen?

I asked this very question of an expert and he said that the egg basically self-destructs. This does happen, in the case of particularly soft eggs. It would not get as far as an embryo because the placenta would malform and be unable to implant due to the double coding going on (two leaders ordering different things and the do-ers can't work together). Same thing happens in animals.
[edited to add] The only time that I know of that a woman would likely have soft eggs is advanced maternal age, but I don't really know.

I was told this wasn't possible because when the sperm reaches the egg it puts some kind of coating around it, so other sperm can't fertilize it. As for identical twins, one sperm fertilizes one egg and that egg splits into two very early in the pregnancy.

I don't think that this would be possible. The egg will have 23 individual chromosomes, which have to match up with the 23 chromosomes in the sperm. It is only when this match has occurred the the nucleus fuses, cell division starts and the baby is on it's way.
If the second sperm were to get in, there would not be any spare chromosomes for it to match up with.
In the case of Down's babies, there are an extra set of chromosomes, which generally come from the Mother, but can also come from the Father.

comparable twins come from one egg it is fertilized via one sperm. in the preliminary cellular divisions, it splits to form to comparable embryos. Fraternal twins are 2 eggs, each and every egg is fertilized via its very own single sperm. those twins could seem lots alike because of the fact they have the comparable mothers and fathers, yet they're genetically no longer the comparable. What you advise won't paintings. If 2 sperm have been to fertilize one egg, there could be too lots genetic concepts for one embryo and not adequate for 2. ensuing embryo will die early in progression as this in basic terms isn't nicely suited with existence.

It can happen. It is called polyspermy. Sometimes, the egg fails to produce the protective barrier that keeps out additional sperm. The resulting embryo has way too many chromosomes, and it dies quickly (within a few hours).

There is a chemical that is immediately released once the first sperm penetrates to make it impossible for another to do so. If ti WERE to happen the baby would just not develop and would result in an extremely early miscarriage.
