The Basics - Stretching Theoretical Physics
Relative Time (the Universal Time Factor)
The Absolute Density of the Universe (the Bucket Factor)
The Basics:Time travel is the concept of moving between different moments in time in a manner analogous to moving between different points in space,either sending objects (or in some cases just information) backwards in time to a moment before the present,or sending objects forward from the present to the future without the need to experience the intervening period (at least not at the normal rate).Some interpretations of time travel also suggest that an attempt to travel backwards in time might take one to a parallel universe whose history would begin to diverge from the traveler's original history after the moment the traveler arrived in the past. It's all outthere:Antigravity,Zero point energy,Warp drive,Faster-than-light travel
One of the Physicists is Ronald Mallett.Mallett is developing a prototype to explore sending a neutron particle along the kind of curve he postulate,a process called Space-time Twisting by Light
To understand quantum mechanics,subatomic level and quantum realities there is no absolute time,or length.Time is merely ideal,an illusion...unlimited duration.Time is a dimension in space-time no different from any other dimension."Time" is the passage of one moment to the next.Everybody knows that time exists,and it exists everywhere.Yet,we cannot see,touch,taste,smell,or feel time.This is because we are trapped in the 3rd dimension. Are you still there...?
Now,there are several possible types of time travel:Viewing the past,Participating in the past,Viewing the future,Participating in the future.
Definitions dimensions
Imagine one dimension as a straight line on a piece of paper.Another line crossing it at a 90 degree angle shows a second direction,forming a cross on the paper.To add a third direction perpendicular to both,imagine a line passing through the center of the cross,leading above and below the flat paper."The next dimension is in a direction perpendicular to all three of those lines,a direction that we as humans are not able to see."Now,when you imagined a line to represent one dimension,you also imagined the line to be somewhere--on a piece of paper,for example.But that paper exists in at least two dimensions.Thus,for a line to have any real location or meaning,it must exist within a two-dimensional or larger space.The line itself describes only one dimension,but its location must be described by two."Similarly,a two-dimensional cross con certainly exist alone, but to have real meaning,it must be located within a three-dimensional space from which it may be observed."The conclusion of this line of reasoning is that any being who perceives a given number of dimensions must exist in a space that has a greater number of dimensions to percieve those dimensions/ at least one more and possibly several."Thus,there must be infinitely many dimensions must exist,since each 'depends' upon the one above it to exist
Time conceptions:
1 - Time is not universal,which means our time is not the same on any other place in the universe
2 - Time is not absolute and so acts on a different rate
3 - We humans on Earth are living in the third dimension- 1.up and down - 2.left and right - 3.forward and backward as x,y,z.But there is 1 more dimension:Time also called the fourth dimension,so infact we live in a fourth dimension,..Space time.If you look up to the sun,you look at the sunlights past,because it takes 8 minutes to travel 148 million kilometres to reach Earth.In studies we know that mass is bending spacetime,light has no mass,but light holds energy,and speed slows time
Now what do we need to travel through time?
Speed,gravity,and project funding to build this technology,in other words we must manipulate our spacetime.If you think about this,its becoming more obvious.The faster you go the slower time gets for you so space-time could be stretched and shrunk
Now there is something funny or mysterious about the fifth dimension.The fifth dimension is a hypothetical extra dimension beyond the usual three spatial dimensions and one time dimension of relativity
Remember nothing is impossible even time travel as we search it

President Barack Obama:
If U.S. astronauts land on the moon again before 2020,it won't be aboard a NASA spacecraft.The space agency's 2011 budget,reveals plans to scrap the Constellation program,including the rockets and spacecraft that NASA has been developing over the past four years to replace its aging space shuttle fleet.
