Formula to disprove going faster than speed of light?

Question

So my science teacher asked us for a formula to disprove going on a ship and walking forward and thus going faster then the speed of light, im thinking some formula where movement = 0 thus making it impossible, but not quite sure

err where the ship is going the speed of light and walking forward

Answer 1

The idea is that the speed of light is the same for both the ship, the passenger, and an observer not on the ship.

For example, if the sheriff is pursuing the bootleggers at 90% of the speed of light, and the deputy fires a bullet straight ahead at 20% of the speed of light, the sheriff and deputy will observe the bullet traveling at 20% of the speed of light. Grandpa on the porch beside the road will see the two cars moving at something less than 90% of the speed of light, and the bullet will be traveling at more than that, but less than the speed of light.

A formula experimentally determined by a fellow named Fizeau gives the sum of two velocities (in this case the deputy and the bullet) with correction for Einstein's theory of general relativity. The formula is:

u = (u' + v) / (1 + u'v/c^2), where

u is the total velocity
u' is the velocity of the bullet
v is the velocity of the deputy
c^2 is the speed of light, c, squared

No matter what the velocities u' and v are, it is impossible for u to exceed c. There are corresponding formulas for time dilation, momentum, and energy.

Following is a reference to Cliffs Quick Review. There are more prestigious books on the subject, and there are more popularized versions complete with silly cartoonish drawings, but for a simple, short statement of the subject, you can't beat Cliffs.

I think the FTL neutrinos are misleading. First they were tracked through mass, not vacuum. Second, even though we assume neutrinos cut through mass like a hot knife through butter, I'm guessing there really is some interaction between the medium and the few neutrinos caught breaking the speed limit. So I'm guessing the speed limit in a vacuum, which is the theory of relativity speed limit, will remain intact. The Lorentz transformations, when applied to hadrons in the LHC, work. And they contain that c for light speed in a vacuum. So even if we can get something, like almost mass less neutrinos up to C > c, that doesn't negate all those practical things like the LHC, nuke power plants, and the H bomb. I frankly am more excited about the Bohm-deBroglie pilot wave experiments done by Couder et al These show that particles are just that... particles. And that their associated waves are actually waves in space-time around them... no more wave functions. If the pilot wave model stands the test of skeptical science, this could throw quantum mechanics into the same trash can where the flat earth was tossed centuries ago. So if I could... that's the discovery I'd like to make, to throw out all that QM silly stuff that even those who deal daily in QM admit have no clue why or how these weird things happen. I'd like to develop the theory of everything based on pilot waves. Finally, Newton. I love his figs. No, really, given what Newton accomplished and the inimical social, religious, and political environment he did it in, Newton's radical gravity and motion laws were minor miracles. Although history buffs tell us Sir Isaac was not a very pleasant person to get along with. He was a bit of an intellectual snob I understand.

The formula for the Speed of light is as follows;
C^2 = The pressure of space divided by the density of the micromass particle of light.

Since the Universe's Pressure gravity field is not homogenous it follows that the speed of light is a function of space pressure.
Hence since light contains the densest mass of the Universe ,it follows that it is the fastest moving micromass particle.

If two mass structures could theoretically approach each other at the speed of light ,and move relative to the same frame of reference, the collision velocity is always less than the sum of the approach velocities. The velocity of collision formula is derived from the Energy sum at collision.

Its very vely simple
