A theory for dark matter
 

Dark matter=Gravitational potential energy mass equivalency


The logic goes as follows-


Just after the big bang particles of the universe would have to posses a velocity
approaching a high percentage of light speed, necessary to escape the enormous
gravitational pull of the early universe,which would likely approach that of a black
hole.

The early universe with its very high energy particles would have a much greater
mass than the universe of today with its much lower energy particles.

I contend that the mass loss doesn't happen from the early universe, to today's
universe.The kinetic energy or mass of the high seed particles is converted to
gravitational potential energy, and according to Einstein's mass energy
equivalency,I would suggest that potential energy should have mass equivalency.
This would explain the missing mass or dark matter of the universe.
Therefore the energy of the universe remains constant and the mass remains
constant as well.

Particles were being carried along with the space-time expansion faster than (relatively weak) gravity could ever have pulled them back together within space.

Particularly during the inflationary period, space was expanding far faster than light-speed. Motions due to gravitational attraction were insignificant in comparison.

What it is, is matter that exerts gravitational force, but does not seem to interact with electromagnetic force. (Some think it could also be ordinary matter that simply isn't emitting detectable radiation in its particular circumstances, but is capable of doing so in other circumstances.) We can't see it directly, and so until recently didn't know it was there, but it was never "missing" -- it was there all the time.

That maybe true, but simple mechanics still hold as far as this is concerned, the universe the universe's intial maximum outward expansion
velocity is due to the force of the explosion. Since gravity is the only
known brake on the expansion speed of the universe,the maximum
expansion velocity of the universe is when the force of gravity equals the
force of the explosion,then gravity takes over to slow the expansion speed.Scientific measurements indicate that the expansion of the universe
has been slowing for billions of years and only recently has it's speed of
expansion been increasing.I believe that the universe is now in a compression mode collasping to another big bang due to properties of
the universe that are not understood now.What I am saying is the
mass of the universe has to be measured at its maximum expansion velocity, this mass remains essentially constant forever.

(1) It was not an explosion within space-time, where "force of the explosion" would be relevant, but an expansion of space-time itself, [u][I]where "simple mechanics" do [B]not[/B] hold![/u][/I]

(2) The [I]initial[/I] outward expansion was _not_ the [I]maximum[/I] outward expansion. The maximum outward expansion occurred later, during the inflation phase.

Seriously, read some Big Bang theory description that explains the difference between an explosion of the type we're familiar with -- within space-time -- and the "Big Bang" expansion of space-time. The physics that apply within space-time don't work for expansion of space-time.

The terminology of a physical explosion that imparts outward momentum to matter that subsequently proceeds outward with declining velocity (due to gravitational attraction back toward the "center") is not appropriate to the Big Bang situation. (It has often been lamented that the name "Big Bang" tends to give the misleading physical-explosion idea about its nature, but no one's come up with a widely-accepted better short name yet.)

All of Einstein's formulas were based on the conservation of linear
momentum, before the collaspe of the previous universe the you had a net maximum inward momentum after the beginnings of the new universe would have an equal and opposite outward momentum.
Space time has no bearing on the total energy or mass of the universe
at its maximum momentum with respect to a stationary observer,
therefore the correct mass of the universe should be calculated at its
maximum momentum, with respect to a stationary observer.

Nope:smile:

Carl, I truly believe that you should understand SR and GR before attempting to replace them.
