Blackholes, Whiteholes and Wormholes?

To keep it easy, Two Black holes when combined by a throat or tube is a Wormhole.

Therefore a wormhole means something which has two black holes as two Mouths connected by a tube. For example:

()====()

here () is a Black Hole
===== is the throat

and ()=====() is a Wormhole.

As you know that Black holes attract every object towards it, so to come out of other black hole is impossible. For this concept of White Hole is proposed.

A White hole is a something opposite to a Black hole, it pushes out particles rather than attracting it.

In an Article about UFO travelings:

" They create controlled Blackhole at the entry and a controlled Whitehole at the exit. The UFOs first accelerate to the center of the tunnel using gravity of the Blackhole characteristics and then use the controlled exotic matter phenomenon to get out of the tunnel through the Whitehole. Artificial wormholes simulating Blackholes are needed for space travel and time travel within the physical universe. That is exactly what the alien civilizations use to travel instantaneously through time and space."

Wormhole could Allow Time Travel?

wormhole could allow time travel. This could be accomplished by accelerating one end of the wormhole to a high velocity relative to the other, and then sometime later bringing it back; relativistic time dilation would result in the accelerated wormhole mouth aging less than the stationary one as seen by an external observer, similar to what is seen in the twin paradox

However, time connects differently through the wormhole than outside it, so that synchronized clocks at each mouth will remain synchronized to someone traveling through the wormhole itself, no matter how the mouths move around. This means that anything which entered the accelerated wormhole mouth would exit the stationary one at a point in time prior to its entry. For example, if clocks at both mouths both showed the date as 2000 before one mouth was accelerated, and after being taken on a trip at relativistic velocities the accelerated mouth was brought back to the same region as the stationary mouth with the accelerated mouth's clock reading 2005 while the stationary mouth's clock read 2010, then a traveler who entered the accelerated mouth at this moment would exit the stationary mouth when its clock also read 2005, in the same region but now five years in the past. Such a configuration of wormholes would allow for a particle's world line to form a closed loop in spacetime, known as a closed timelike curve.

Wormholes

Wormholes let you travel from one part of the Cosmos to another in an instant.

A wormhole has at least two mouths which are connected to a single throat or tube. If the wormhole is traversable, matter can 'travel' from one mouth to the other by passing through the throat. While there is no observational evidence for wormholes, spacetimes containing wormholes are known to be valid solutions in general relativity.

The term wormhole was coined by the American theoretical physicist John Wheeler in 1957. However, the idea of wormholes was invented already in 1921 by the German mathematician Hermann Weyl in connection with his analysis of mass in terms of electromagnetic field energy.^[1]

This analysis forces one to consider situations...where there is a net flux of lines of force through what topologists would call a handle of the multiply-connected space and what physicists might perhaps be excused for more vividly terming a ‘wormhole’.

– John Wheeler in Annals of Physics

The name "wormhole" comes from an analogy used to explain the phenomenon. If a worm is travelling over the skin of an apple, then the worm could take a shortcut to the opposite side of the apple's skin by burrowing through its center, rather than travelling the entire distance around, just as a wormhole traveler could take a shortcut to the opposite side of the universe through a topologically nontrivial tunnel

Time Defined?

What is time?

I have had the opportunity to read something valuable. I read that this universe has two properties, one is Space and the other is Time. It is believed that this Universe should have been created many ages ago, How many ages? Some say Big Bang. But you have to agree that even before Big Bang there was Time and Space because we cannot think something which is beyond time, something beyond space....

Confirming the views that everything exists in time and space is only because of Ignorance. Mind is limited. You cannot even think of discovering something beyond time and space with mind. Because even thought searches for everything in this Space.

It is clear that 'Nonsense' is not the word for something which is beyond time just because our mind cannot perceive it! Who knows when the thoughts cease what happens? Maybe, then time travel is possible...
