      Quantum Gravity in Everyday Life: General Relativity as an Effective Field Theory

      by Cliff P. BurgesThis article is meant as a summary and introduction to the ideas of effective field theory as applied to gravitational systems, ideas which provide the theoretical foundations for the modern use of general relativity as a theory from which precise predictions are possible.

        What is time?

        by unknown author.It is commonly asserted that in general relativity there is no absolute simultaneity. On the other hand, it is asserted that, based on the traveling time of light, we see the Sun as it was 8 minutes ago and the Andromeda nebula as it was 2.5 million years ago. This seems to conf...

          A theory about the cause of gravity

          Einstein was wrong assuming that Gravity is caused by mass - Gravity is caused by a  matter -antimatter energy potential by mass (quarks) in view to the quantum vacuum and vice versa. In order to tell mass from energy in a quantized potential, an observer has to take into account the plane ...

            Some questions about the cause of gravity

            Questions: 1. Is gravity a force? 2. What do you think is the way mass is coming into existence within the quantum vacuum implying? 3. When you flip the observational plane and think about: What effect has micro gravity for the formation of planets, stars or galaxy clusters? 4. Does a magnet ...

                Five unsolved problems in Theoretical Physics by Michael Balmer

                Five unsolved problems in Theoretical Physics ,there are more so i don’t want anyone to think we only have five,even of the five there is only one to discuss being more important than the others. Problem 1 :Combine General Relativity with Quantum Mechanics Problem 2:The foundations of Qua...
