How Many Dimensions Does The Universe Have?
Dimensions are complicated, and wrapping your mind around how many there are can give you a headache. Join Trace as he explains everything you should know about them.
What is a dimension, and how many are there?
"As you've probably noticed, we live in a world defined by three spatial dimensions and one dimension of time."
Imagining Other Dimensions
"For most of us, or perhaps all of us, it's impossible to imagine a world consisting of more than three spatial dimensions."
"We all consider dimensions in general terms such as another reality or how we perceive the environment around us."
How Many Dimensions Does the Universe Really Have?
"An engineer, a mathematician and a physicist walk into a universe. How many dimensions do they find?"
Extra dimensions, gravitons, and tiny black holes
"Why is gravity so much weaker than the other fundamental forces?"
Scientists suggest spacetime has no time dimension
"The concept of time as a way to measure the duration of events is not only deeply intuitive, it also plays an important role in our mathematical descriptions of physical systems."
Theoretical physics: The origins of space and time
"Many researchers believe that physics will not be complete until it can explain not just the behaviour of space and time, but where these entities come from."
