Temperature in Space:

When there is no energy there is no matter in space, therefore there is no temperature.  The zero points in space without energy or matter can have no temperature.  So space without energy or matter is the coldest of cold infinitely cold.  When energy and matter is absent you have zero, zero heat, zero time, and zero light. 
Time in zero space is literally frozen and this space without energy or matter is frozen in time.
The energy expelled by the sun needs matter to create heat, otherwise the suns energy would heat space, and it doesn't,  space without matter cannot be heated.  We can feel and see the Suns energy because we are matter. 

If suddenly the universe fell into complete darkness, with no reaction between space and the energy of matter all life would end or freeze instantly!

 Genesis 8:22
"As long as the earth endures; seedtime and harvest, cold and heat,
 summer and winter, day and night will never cease." Sounds a little Deistic to me.

Time in space:

In empty space as mentioned above, time is frozen;

It is common knowledge that if you were to be frozen for a million years and then could be revived, you would not age or know how much time had passed... You would of been frozen in time and space.

Matter is what sets time in motion, the moment matter occupies space is the beginning of time for that matter. Time is how long matter can exit before space reclaims the space being occupied by that matter. 
Therefore the amount of time an object can exist in space depends on the amount of mass and energy that object has to fend off space.

It may be possible to travel from one zero point in space to another zero point in space, in near zero amount of time, but you cannot arrive at a time in space in the past or the future.  All time in space exist relative to space itself... As on earth you can tag time zones with different numbers, but they can only exist relative to each other.

Space cannot eliminate matter... the amount of matter and energy in space remains constant and can only be redistributed, that is why I believe a black hole in space is the beginning and end of time, energy and matter in space.  Energy, matter and time will be recycled in space forever.  

Earth shares its time in space with our galaxy,  other galaxies have their own relative time in space.

Time Travel:

Can humans travel into the future to change the past? 

At first this sounds farfetched and not possible.
(unless we can make a quantum leap through a zero point in space.)

However, I believe we can go into the future to change the past... to a certain extent! 

This led me to realize that our thoughts can be transformed into visions of our future.

Through visualization and meditation we can go into the future to change our past. 
For example, if you wanted two dozen eggs in your refrigerator.  You can sit down visualize yourself going to the store, purchasing the eggs then going home and placing the eggs in your refrigerator.  Then you can act out the process physically and from that point on you will have two dozen eggs in your refrigerator. 
However, if you think you want two dozen eggs in your refrigerator but never act on the thought you will not have the two dozen eggs!  So from the point you physically act out your thoughts, you have changed the future and the past. 

You can use meditation and visualization as a way to help you achieve many of your goals.
Which will in fact alter your future and therefore you’re past.

You can also visualize your past, your past is nothing more than visualizations we call memories, and visualization of our future could be called our "memory" of the future.  
Due to other forces of nature we cannot completely control our future, the same as we could not completely control our past.

I don't believe we can move the physical matter of our bodies into the future or the past. Yet? 

Note:  Sometimes I receive emails of false but perceivably realistic situations.  The way I see it is;  If the information in these emails were to be acted out by someone then one man's thoughts could become another man's reality!
I might forward these emails to others...  not as a factual event, but more as a warning of what could be.
