But basically scientists now believe that the particles that makes up quarks aren't dots as atoms and protons and such often are made out to be. Instead the quarks are made up of strings and loops.If they are made up of strings and loops then that would explain a lot of stuff the scientists can't really explain. (Don't ask me what, though). The problem with the string theory is the only way for it to work is if those loops has access to more dimensions. (Of course the four dimensions we can experience is the three spatial dimensions plus time.)After a lot of calculations the scientists came to the conclusion that the strings need 11 dimensions to work. And why we can't experience the rest of them is simply something that we'll have to live with. <img src="https://cdn.jsdelivr.net/joypixels/assets/8.0/png/unicode/64/1f642.png" class="smilie smilie--emoji" loading="lazy" width="64" height="64" alt=":)" title="Smile    :)"  data-smilie="1"data-shortname=":)" />Still, and this stuff gets more interesting all the time, if you think of slices in a loaf of bread we can only experience what happens in our slice even though the neighboring slice is just nearby, almost upon us. But if there are more dimensions it matters little if there can't be an exchange between the slices. But there is exchange!They have come to the conclusion that gravity might be a force that transcends dimensions whereas nothing else does. They were at first baffled by the fact gravity is such a weak force. You can hold an apple into the air easily and without fear of the conflict between your muscle force and gravity harming you. Something that can't be said about electromagnetism for example. The reason that gravity is safe is that when you manipulate it it withdraws into other dimensions instead of fighting right here right now.The string-theory is further extended by the M-theory which says that everything is made up of strings and membranes. For example our universe might be a wafer thin membrane (although "wafer thin" in 11 dimensions). Our membrane, or brane, is hanging in hyperspace like a bedsheet out to dry. Next to it are other branes. If they occassionaly touch each other big bangs are created! A scary notion.</blockquote>
