Your outline of the philosophical and historical outlines of 20th century physics is spot on. But you also correctly point out that its all just pointless navel gazing until it is actually confirmed by observation and experiment. That’s what scientific amateurs and dilettante philosophers can never seem to get through their heads.

This isn’t just some abstract quirk of mathematics- this is real, verified countless times a day in particle accelerators.

The relativistic kinetic energy can be written as (Gamma-1)*m*c^2 (TOTAL energy minus the rest mass energy)… It takes a little math, but it is straightforward to show that when v<<c this reduces to the classical kinetic energy 1/2*m*v^2

Einstein's equations (in both Special and General Relativity) and their implications have been verified countless times and have been found to describe reality with extreme accuracy- much of our modern world has been built around those equations.

Which is why I find it odd that so many crackpots pick on Einstein and claim they have a better alternative to his theories…

It is not as if Einstein just wrote down random letters in equation form until he found a combination that happened to work out…
E=m*a^2
E=m*b^2
E=m*c^2 EUREKA!!!

No, he started with the reasonable assumption that the laws of physics must hold for all reference frames, and then looked at what that implied- he didn’t CHOOSE how the equations came out, it was dictated by the universe, he just had the genius to figure it out.

He listened when the universe told him just how weird reality was- length contraction, time dilation- just imagine how alien and unbelievable all that must have been at the time… yet he had to accept it, and eventually everyone else did too- because the derivation was elegant, and had no holes in the reasoning… and most importantly, the experiments showed he was right.

As wonderfully accurate as it was, the theory of special relativity was incomplete- — but given the indisputable accuracy of the theory of special relativity Einstein worked to figure what those few holes in the theory were telling him- this was a much more complicated task, and the results were even more bizarre in their description of reality… this was the General Theory of relativity- This filled in the gaps, and again- most importantly- has been verified countless times by experiment and observation.

The nature of reality it revealed was even more alien to our everyday experience- mass and energy affect the fabric of space and time…

Einstein did not disprove Newton, Einstein showed that Newton’s laws were actually approximations that are extremely accurate on the velocity and energy scales we experience in everyday life. You can very accurately send a space probe to jupiter using only Newton’s laws- General relativity likewise did not disprove special relativity, it expanded upon it.

It is probable – at least scientists certainly hope so- that there will be a more complete theory that unites General relativity and quantum mechanics, this theory will look very different than any that came before it- but we do know that it will not ‘disprove’ general relativity or quantum mechanics- it will show how they are connected.

There are a few contenders for paths to this larger theory, the one that I personally find most appealing based on my view of the nature of reality is Loop Quantum Gravity, but I am in no way qualified to evaluate any of the contenders based on their scientific and mathematical merits… its just too outside my fields of study.

I have a pretty good grasp of Newtonian mechanics, but don’t delude yourself that you can make any progress whatsoever in modern physics until you are comfortable with Classical. But the Einstein equation is very easy when expressed dimensionally. And by “dimension” I mean units, not coordinate systems. That’s critical.

E = Mc^2
E = kg (m/s)^2
or
E = kg m^2 / s^2

The unit for energy, kg (m/s)^2, is the Joule.

I’ve never heard of U, before. Neither has anyone else. Did you just make that up?

Oh, and by the way, none of this (from your post above) makes any sense

In other words: Energy = (u/k)c
M= (U/k)/C
E= (U/k)*C
C=300,000,000 m/s
U= (300,000,000 * k^2) / M
k=m
MY calculation
If m=2…… U= 2^2 = 4 * 300000000 = 1,200,000,000 /2 = 600,000,000 * 300,000,000 = 1.8*10^17
Einstein’s formula; E=mc^2
Calculation
300,000,000 * 300,000,000 = 9*10^16…..* 2 = 1.8*10^17

Its all gibberish, Johannes, it makes no sense at all.

For example, the acceleration of gravity near the earth’s surface is 9.8 meters per second per second. What this means is that a falling object will increase its velocity by 9.8 m/s every second.

If an object is dropped from a building and it accelerates at 9.8 meters per second per second for 5 seconds what is its final velocity?

Velocity v (in meters/second) is calculated by multiplying the acceleration a (meters per second squared) by the time t (seconds); as follows:
v = at and substituting values and units
v = (9.8 m/s^2)(5 s)
v = 49 m/s

the seconds unit in the time value cancels out one second unit in the denominator of the acceleration value. The units of the v value are now appropriate for a velocity, because velocity has to have a unit of meters per second. If your v value had come out with units of say, s, then you would know you made a mistake somewhere along the line.

Another example
The distance d traveled by the object under acceleration a over time t is given by the equation

d = 1/2 at^2 or
d = 1/2 (9.8 m/s^2)(5 s)^2
d = 1/2 (9.8 m/s^2)(25 s^2)
d = 122.5 m {The s^2 terms cancel out).

Dimensional analysis helps keep track of your calculation by demonstrating that the units of the result make sense considering the units of the other factors in the calculation. It serves as a check on your work. Until you learn how to do this, your mystic revelations will remain gibberish, they will have no relation to either mathematics or physics, no matter how many websites you quote out of context to try and justify your preconceived opinions.

I’m sorry to be so harsh, but by continuing to make these mistakes you embarrass yourself far more than any one of us can humiliate you. Ignorance alone is no disgrace, but failure to recognize it, and correct it, is.

20 years, and countless explanations of why this is nonsense and he still keeps coming back to dump this crap here whenever he goes off his meds…

I think that: “velocity” can exist from almost “0” to at least to the speed of light,
meaning that “time” only gives the velocity a numerical value, and the numerical value can be removed without removing the motion of “whatever” has the velocity.

You can ‘think’ whatever you like, your statement makes zero sense.

m = mass that contains “kinetic energy”. Mass and the intrinsic kinetic energy have the same numeric value.

This makes no sense, Johannes- I read (and write) scientific papers as part of my job… you are spouting delusional nonsense, nothing more… your understanding of physical quantities is not just flawed- it is nonexistent.
