Is Time Travel Possible Through Mental Projection?

[AWolf]

X-ray and Gamma both being "photon" aren’t massless.

Gamma ray
a discrete quantity of electromagnetic energy, without mass or charge, emitted by a radionuclide. They cannot penetrate lead or a large thickness of concrete. See x-ray.
X-ray
a discrete quantity of electromagnetic energy, without mass or charge, emitted by an x-ray machine. See gamma-ray.

These are definitions pulled from one of many web sites.

An electron has a mass of 0.5MeV which is in the range of gamma rays. Just because the energy of the gamma ray is quoted as being 0.5MeV doesn't give it mass, just similar energy.

If any photon had non zero rest mass, then it's relativistic mass would be infinite.

Would this be a be a fair assumption?

The assumption is fair only if we take spacetime into consideration. The time in spacetime is one dimensional and it has two directions. The space in spacetime can be contracted to one dimensional and it also has two degrees of freedom.

I mentioned the Friedmann equation and the curvature parameters.

Include in this http://superstringtheory.com/cosmo/cosmo21.html.

There are a couple of models here for consideration when we include time.

Dirac Matrices come to mind, as well as listing the two other references for a dynamical realization.

Omega =1?

Does this seem consistent?

 

[Antonio Lao]

sol2,

I am starting a thread entitled: Inside and Outside Spacetime.

If omega is greater than 1 then, I think, even a vantage point outside of spacetime will not be able to see inside the universe.

If we can make the assumption that each elementary particle is a microcosmos and each has its own omega, this omega cannot be greater than 1 since we can derive properties of mass, charge, spin, and magnetic dipole moment.

Time is, we are. Things exists in what is.

 

[Francium]

It is all circular motion. Time can be measured in its different realtivity according to one place in the universe if and only if, the universe is spherical that's just as crazy as saying that Jupiter has a storm the size of Earth on it. the universe must be spinning also and that time can be measured from this point and possible along the axis.

Does mass-energy relation false today? I mean E=mc^2.
If no, then:
“ Two objects having equal energy would have equal mass”.
It’s right.

But any object with rest mass would have infinite mass when traveling at lightspeed. What AWolf said was that a photon has no rest mass.

Equation To Find Number Of Dimensions

May,20,2004

A GENERALIZED EQUATION TO CALCULATE NUMBER OF DIMENSIONS

Sometime ago Dr.Syed Ameen had derived an equation,(see http://www.superstringtheory.com,postings , which can be used as a generalized equation to calculate the number of dimensions for any phenomenon or event or situation.The equation involves the tiotal number of VARIABLES( V ),in any natural phenomenon or event or happening.The number of DIMENSIONS( D ),are always less by one( 1 ).
Therefore the generalized equation is:

D = V - 1

To test the validity of this Dr.Ameen's equation to calculate total number of Dimensions,for example take Gas law,and it will prove to be right.In the same way this can be applied to any other phenomenon.

There are no objects with rest mass traveling at lightspeed.
