In my previous post I made the statement that matter can be converted into energy.  Although this can be observed in the macro world, it is not true in the micro world.  In truth, in any process, mass in conserved and energy is conserved.  What we observe is the conversion of one type of matter into another and the conversion of one type of energy into another, but there is still the same amount of mass as before as well as the same amount of energy.

Gravity is an interesting subject, and is being studied in depth by the scientific community with huge experiments.  What is being searched for is the Graviton.  Current theory is that gravity acts like a wave and travels at the speed of light.

Mark, thank you for the responses, I defer to your obviously deeper understanding of the subject matter as I am strictly an amateur with an interest in all of His creation.

Back to my original question, since the pros and cons of traveling at the speed of light for mankind is to this point only theory and again not provable in lab conditions let me pose my original question as strictly hypothetical, if the sun disappeared without expolding but retracted or became a Quasar or black hole you are saying the effect would be an 8 1/2 minute delay and not instantanious? That the effect of the sun's former gravity would still effect the outer planets for months and not disturb their orbits?

Please forgive my neophyte terminology or analogies and I do appreciate your patience.

Thanks,

Joe

the reason time travel is impossible is because time is how God brings about his purpose :wink:


the concept of a being NOT bound by time OR space is mind boggling.


cool thread, Jesus is master scientist :wink:

Joe,
The only scientific answer I can give at this time is that according to "current theory" is that it would take as long for the gravity to abate as it would take for the light to cease.  Scientists continue to hold to the theory that nothing in the observable physical realm travels faster than light.  The current theories of special and general relativity are established based on this assumption.  

Quasars and black holes are very massive objects and have so much gravity that even light cannot escape.  The real problem in trying to establish an answer to your question is how to remove an object with gravity instantly.  It would take infinite energy to to do so.

Consider this: according to relativity theory, the faster an object travels, the more massive it becomes and time proceeds more slowly for the object as observed from the outside.  If I could travel at the speed of light, time would appear normal for me but in actuality it would stop. What that would mean is that I could travel between two distant objects in zero time.  That would mean I would be in both places at the same time, or essentially everywhere at once.  Sounds like God.

Time travel -

Forward is easy, we are doing it right now.

Backwards I believe is not possible because it would violate the conservation of mass and energy.  If I could travel backwards to yesterday, my yesterday self would be there and my today self would also be there at the same time.  This would add my current mass to yesterday thus increasing the mass of the universe just a bit.  Not allowed by current theory.  If I sent 1000 gallons of gasoline backwards to yesterday it would increase the energy of the universe.  Also not permitted, but it sure would solve the energy crisis.
