String theory basically states that all objects including everything on Earth is made up of atoms. And as we know, atoms are made up of protons, neutrons and electrons. What's made them then? Quarks. Then, what happen when we sliced up a quarks? Energy. But as complicated as it may seems, we do know by physics and chemistry that energy is just an abstract thing human use to define the feeling we felt when being touched and is always in calculation form. You can never really see energy right? or is that you haven't discovered it? Let's say, energy made up the quarks and quarks made everything on the Earth, the notebook you are using now, the book you are reading... But if it is so, then we can say Energy=Quarks=Atoms. Then, we do know that energy is everything. But of our science understanding (or that my understanding in science is too shallow) since energy is abstract, then how come now whatever we are seeing now is so concrete if everything is made up of the abstract - energy?
If you already understand the concept, then let's apply to human's lives. If all atoms are unreal, then what are us? You may feel unacceptable now. Then maybe you might as well close this window now as the rest of the concept are going to make you mad if broad-minded is not your choice ^^ By string theory and M-theory, there are, on calculation, 10 or 11 dimensions in the universe. I myself believe in the 23 dimensions. But as we know, a straight line is 1D, x and y axis means 2D, then we are 3D. Then where is the 4th and so on? Einstein proposed the 4th dimensions should be the time. But regardless of anything, we, 3D could see things in 3D to 1D. So, could we said that there are other people in 4D could see us too but we cannot see them otherwise? It's worth the thinking~
Back to the topic again, if i said we all all nothing since all of us are made up of energy which is abstract, then what are us? Remember how the Big Bang theory explained? The explosion of a high-energy atom that exploded and keep expanding, creating new planets on the edge of it's expansion. And so prokaryotes evolved due to favourable conditions, and so after billions of years, here we are. That's yet another theory - Darwin's theory of evolution, which i will just skip it. So, now the Universe is sill expanding and expanding. But as we know, every atom will exert a gravitational force on another atom. Something like that in basic. So, now when new planets are formed, more atoms are formed. There will be one day that the sum of all the gravitational pull > expansion force. So the Universe will undergoes shrinking and back to the origin point again.
Yet again, what i am going to say is that if all of these things are unreal, then why are humans always pursuing things that never existed? What should be the last thing on our mind when we breathe last? We were born, study, get a job, work hard to build a family, earn as much money as we can and then we are on the edge of our life. If we think like that, aren't humans are the one who always creating complications and then try to simplify everything? First of all, are there words in the basis world? Human created it. Are alphabets even existed if no human made it in the first place? What is time? Is time existed too? time is also the after-effect of human to explain the nature since by definition, time is the 1/3.8x10^8 of the speed of light. And yet again, what is light? Light is made up of photons. Yet again, all in all, everything is just the abstract - energy. If it is so, why are human still so obstinate to try to conspire even to the extent of harming other human beings' just for thee sake of own benefits? Aren't they only pursuing the unreal? Even if they really do get the things that they want, is it even the real thing in the first place?
色即是空，空既是色. Buddha saying by the way. It means everything that exist is actually nothing, and nothing is also everything that existed. Doesn't this sychronized with all the research human had done?
In the end, ask yourself, who should be the cause of everything that happen? i could only answer, you will know when you reached that stage of life ^^ haha~
