Nonsense, the confusion is yours.
Einstein invented the atomic bomb and that fact blows your nonsense theories 
you were taught out of the water.

quoting  (I bolded the original text for emphasis)
Albert Einstein from the 
link  <A 
HREF="http://www4.district125.k12.il.us/faculty/bsparaci/sr/Einstein.html">Ein
stein</A> 

quote----
Some people called me amazing. I was born in Germany in the year 1879. I went 
to the United States in the 1930s. I developed the important theories of 
relativity. The famous equation E=MC^2 led to the development of nuclear 
fission and eventually the atomic bomb. My reason for inventing the atomic 
bomb, was because the  received evidence that Germany (my native country) was 
planning to build an atomic bomb. They were going to use it against the 
United States. The atomic bomb was made in the U.S. and in 1945 the United 
States used the atomic bomb. They used it in Hiroshima and Nagasaki. While I 
was attending college Marcel Grossman, a classmate, said, "This Einstein will 
one day be a very great man." Marcel Grossman was right.

Nonsense, You cannot ignore Newtonian physics and see only relativistic 
(observer effects) as important. Einstein's equations use the terms E and E' 
for Newtonian and relativistic energy respectively. The value is different 
and both are valid. It is obvious both observer (relativistic effect) and 
Newtonian physics aboard the spacecraft are calculated by SR equations and 
equally valid.

The E' value you find required is observed from the earth. The value I 
require aboard my ship is E =MC^2. If you will stop mixing frames of 
reference for a minute and observer that to calculate the energy observed 
relativistically you have to use the relativistic mass M' in your calculation 
to prevent mixing of frames. The increased relativistic 1/2 ton mass 
approaches infinity as the velocity approaches light speed.
This real difference in the masses and resulting energy is the factor you 
underestimate the velocity obtainable by my machine.

Nonsense, your wrong, poorly calculated as shown, but forgivable. Einstein 
claimed in 1955 he never said objects cannot exceed light speed and gave the 
reasons I give always.   He said the misunderstanding began when a translator 
for his German SR theory was translated to English. The translator used his 
own misunderstanding and quoted the misinformation attributing his own 
thoughts as quoted as what Einstein said. Widely published in America, by the 
time he got over here and his English had greatly improved he made not 
attempt to correct (until 1955) the public misunderstanding. He focused 
instead on teaching correctly his student classes at Princeton and CalTech. 
Since then I have found no quote or work by any of his actual students or 
Einstein, claiming otherwise.

It is time for you to put up or shut up and listen.
Show me other wise.

Respectfully.
