Why can not we travel faster than light?

Hi,
today I will write just a fun post about why we can not travel faster than light (even then it is desirable… as is written on mathbloggers cool blog: https://mathblogger101.wordpress.com/ ).

So there are some things that will start to happen when you go really fast.
First of all I would like to say that speed cannot be added because it would couse some trouble (like putting headlight of your car ON while driving).
There is simple equation which you can find on internet which says how speeds works when you are “adding” them.
Well another thing is that stuff is gaining mass while it goes faster but there is some effect only in higher speeds. (Athlete girls should not check their weight while running, they could be disappointed.)
It is exponential so you would need to give infinite amount of energy to system to get that speed, which would release infinite amount of heat and that would destroy everything, you just can not take that much of coal.
There is also another problem about which you maybe did not know.
Because this is electromagnetism whem moving around. If you read that post about EM you know that electromagnetic force carrier is photon.
What is the speed of photon? 300 000km/s
That means that photon which is responsible for your moving can not move you faster than it is traveling!
I will not be able to run faster with bricks for building if my maximal speed is 2m/s.

VSauce1 made a awesome point of what would happen with car traveling at speed of light and pushing its headlights on. If you know what is Doppler effect you can come up with the answer really quickly.. It is that WWWWŽŽŽŽŽMMMM of train or car traveling towards and than away from you but with sound. Same thing would happen to car at speed of light. For passenger inside nothing would happen, time would not happen because nothing like lenght which can travel light in one second would not happen for him because from his view light would not move any distance in one second…

PS: if you know about any reason why speed of light is 300 000km/s let me know because I dont
