E=MC2, not any more

If a car hits a wall at 30mph, its a 30mph total collision
If a car hits a car at 30mph and the other car is doing 30mph, its a 60mph total collision
If light hits light at the speed of light what is the total collision speed?

geek hat on.

total collision speeds are a simple newtonian mechanical calculation (V = V1 + V2) to explain what happens to the forces/momentum of an object with mass.

photons are massless and you need to move over to special relativity which would define the formula as V = (V1 + V2)/(1 + V1* V2/c²)

so your answer is tomato.

There is no collision.

Or how to spell 

i'm actualy quite dyslexic and have probaly put more effort in to spelling than most people and to not make errors in spelling usally require me to read through something a few times thats dosent usally happen when posting on forums.    if you wish to take the piss you are more than welcome to do so as long as you do it in person if and when i ever meet you in person. ( i'll leave it up to you to decide if thats a good idea )

 thankfully spelling is not an issue for me in ether of my jobs. in one i have very littel paperwork to do in one of them and the other i have someone to who ether translates my scribbelings or takes notes and types it up.

Thanks for proving my point.

Thanks for proving my point. 

Being dyslexic is not fun and it's not something that you should mock, and it most certainly does not mean someone is thick. Danny has a wealth of knowledge which he has proved over and over, comes on here and helps people out FOC when he charges for doing the same thing at work. Be grateful to people like him, they're the kind that keep online communities a source of knowledge for others.

Yes dyslexia is no fun. At no point was any comment about his intelligence. And I'm sure he has a great wealth of knowledge.

Really?  Is that the best come-back you can make?

Precisely what point of yours did Danny prove?

Always delighted to see people just opening the taps and roaring into the distance in comparison to me in the 'being a c*nt' stakes and you are world-class on the evidence in this thread.
