One of Einstein's founding theories was when an object approached the speed of light it's mass would approach infinity. This in effect would result in no object having the ability to travel faster than the speed of light.
The theory raises a number of issues.

1) Where does the mass come from?

2) How is it created?

Einstein used the analogy by watching trains pass through a station.

Analogies cannot be used to determine a scientific conclusion. There is no relationship.

Mass cannot be produced by analogy extensions, or by extrapolating mathematical curves.

The real problem in Einstein's theory of gravity, it doesn't make sense.
Newton described the force of gravity in his famous gravitational equation. This describes in a mathematical manner how 2 objects interact in space.
This force acts in a straight line between these 2 objects. Therefore the force of gravity acts in a straight line.

Einstein theory is that mass curves space, therefore curves gravity, to produce the effect of what occurs between 2 objects in space.
Einstein predicted that lights relative speed would slow as it approached the sun, which has been proven, but why? Einstein's theory suggests that space is curved therefore light takes longer to travel the distance around the Sun, therefore it appears to slow.

This theory has a number of problems.

!) the galaxy andromeda is flat as a pancake as it extends outward from its centre, which contains a massive black hole. No curvature.

2) Our solar system is flat, with the exception of Pluto. No curvature.

3) The space time distortion from the our Sun as discovery by experiments done in the 60's by Shapiro, indicates that the time space alteration disappears with very small incremental distances from the Sun, therefore this theory by Einstein cannot support the gravity required by the solar system.

When our sun alters time space in it's atmosphere, the Corona, it slows time and contract space, which gives rise to the large temperature difference, from the Sun's surface v.s. its atmosphere. The Corona is caused by the Suns altering time space by contracting space The Suns velocity of gravity or the rate that the Sun contracts space, slows time. The slowing of time is what appears as the slowing of light as it passes by the Corona.

The velocity of gravity is a function of time. The faster a Sun's ability to contract space, the slower the time. As time slows, the slower light's velocity.

Therefore there is 2 distinct actions of gravity

1) The force of gravity, that is defined by the mass of each object, as Newton's equation suggests.

2) The velocity of gravity, which alters time space, through the Sun's ability to contract space at a continuous rate.
The force of gravity maintains our solar system, as planetary orbits.
The velocity of gravity, slows time and alters time space to produce the sun's atmosphere which heats the solar system,(the Corona) and allows life.

To give evidence of this we can exam the black spots on our Sun. These spots can give evidence to a working model to help explain Black Holes. These black spots are not formed because of infinity mass as suggested by Einstein, but by their strong force of magnetic fields. Look closely and their magnetic flux are quite visible.
The same is true with the black holes in the center of galaxies. As star systems approach the centre of the galaxy their speed is reduced, not because their mass is increasing, but because time is slowing.
The movement of galaxies seems to contradict the movement of the solar system .. but they are not the same.

Our planets orbits in the solar system, travel at higher velocities, when they are near the Sun, while planets that orbit further out travel at slower velocities. Pluto's velocity is nearly a walking pace, while Mercury's velocity is very fast.
The opposite is observed in galaxies, because the centre of a galaxy is a Black Hole, which is strongly altering space time.
The Black Hole is comprised of two or more Pulsars orbiting extremely fast in the same orbit. No matter how fast they travel in their decaying orbit they never meet, as they are contracting space, and slowing time by their extremely strong magnetic fields. As time approaches zero, their orbit turns black, as their gravities velocity approaches infinity. This is what Black Holes really are, not infinity mass, but where time stops.

For mankind to travel space, time space has to be altered. This can only be accomplished by building as working model of the Sun and how the Sun alters time and space. Once time space is altered space travel is not limited to the speed of light.

The Sun's ability to polarize space cannot be duplicated on earth, but water can be used instead of space. Water can be easily polarized. Then by duplicating the Sun's specific gravity of 1.3 in a sphere of water, spinning through an axis of a strong magnetic field, the water will transform, and time will slow. In a very specific set of circumstances, will cause this effect.

The slowing of time will renew life.
