surely there would be an infinite amount due to the fact there is an infinite amount of factors that can be changed to create our current state? also how do these clever scientists work all this stuff out!

According to wide theory today, every choice you make, every thought you make, every inaction you don't make creates parallel universes, where what you could not have done in this universe, there is another you who chose to do that.
In simplest terms, if you opened the cupboard to get a packet of chips, but saw biscuits and grabbed them instea, another rwality would have been born from that simple decision to eat the biscuits instead of the chips you were originally going to eat.
Apply that to everything in the entire history of the Earth, and you have an infinte number of parallels.

You know KG... I want to tell you all something about parallel universes.
Parallel universes are a concept that was part of a thought experiment in an attempt to get around Heisenberg's uncertainty Principle.
There aren't any actual parallel universes... It was just a supposition that a sci-fi writer ran away with and it got into the public mind and yours. Here is the short story.
The Heisenberg uncertainty principle states (among other things) that you can't know both the Speed and Direction of a quantum object, because once you measure one of these things the measurement changes the other of these. Soooo... The physicists didn't like this very much (neither do I) so they said... "I wonder, If we measure the speed in this lab here in this universe, does the direction get measured in another lab in a parallel universe?" ... Wow... And to make a long story short... the scientists determined that if this actually happened, and they were splitting off universes every time they made a quantum measurement, that it would still violate Heisenberg's uncertainty principle if there were ever to be communication between universes, so therefore there can never be that either.
Ergo... There never was or is parallel universes and if there is then we can never reach or communicate with them.
Have a nice day! :-)

if there is one, there could easily be millions upon millions more. however this being completely unprovable (especially as i would be ppretty nervous trying to open a hole between two universes as quite literally ANYTHING could happen)
It is a theory that can never be proved or disproved, but like the beginning of so many theories just sounds right, so it gets developed.
at the begining of the universe the major forces of the universe - strong & weak nuclear, magnetic and gravity were created from one super force that split into 4 smaller forces, if the split was slightly differant imagine how strange the universe would be.
there is probably even a world out there with chocolate hills and seas of beer. anything is possible

OK let's assume the density of our universe is just sufficient to allow infinite expansion. This would require excepting for dark matter about 10^80 proton equivalent particles. Rearrange them as you will in space and time, if alternative universes exist with similar properties, all of them will begin to repeat themselves at a distance of about 10^96 LY's. After that no matter whether the No. of universes is infinite countably, the number of distinct ones is finite.

Sorry for depressing you all, but it is an idea developed by a science fiction writer, so he/she could make money, that's all. You can create your own, for example; impacted realities, event endings, time rejection theory etc.
Don't waste any more of your life thinking about it. Unless you want to start writing Stargate stories, or become a writer yourself, in which case, waste away.

As many as is needed to make the models/theories work. (Just as dimensions can be used to model curves as straight lines)
There are different types of infinity. Sounds like you are wanting to "count the possibilities" off. If branching of options approach is taken it sounds like the set of possibilities is an uncountable set. It doesn't have quite the same meaning as infinite.
Its impossible to count any disconnected universe or systems of universes which have no link/aren't observable FROM our universe.

Pick a number, but to me there can any number of universes but this parallel thing is for the birds.

An infinite number. Where every single option is considered.

As many as the stars in the sky. As many as the unfathomable questions asked on this subject.
I guess because these scientists are just CLEVER!

I think it was only 4 or 6.
