Can you have fire in igloo? Did you know you can stay extra warm in an igloo with a fire, without it melting? The fire needs to be in the centre of the igloo so it’s furthest away from the walls...

Is it possible to slow down your perception of time? Unfortunately, there is no way to slow down time, however, there are some tips and tricks that could help you slow down the perception of time. Being more mindful and present...

How do igloos work? Because ice’s thermal conductivity is low, like the thermal conductivity of air, an igloo works by stopping heat being transferred into the surroundings, even when the temperature is really low. The ice and the still, unmoving air...

Are igloos actually warm? Temperatures outside can sometimes reach up to minus 45 degrees (chilly!), however, inside an igloo, the temperature can be anywhere between minus 7 and 16 degrees because of your body heat. It’s not going to be warm...

What does it mean when the smoke follows you? Campfire smoke follows you because your body acts as an air dam. It blocks air moving toward the fire, creating a vacuum so smoke moves toward you. If you move, the smoke...

What is momentum in physics definition? Momentum is defined as the quantity of motion of the body. It is measured by “mass × velocity”, as momentum depends upon velocity, and it depends on the direction of the motion of the body...

What is a simple definition of momentum? : strength or force gained by motion or by a series of events. The wagon gained momentum as it rolled down the hill. What is a momentum in physics? Momentum is defined as the...

Does space actually bend? Space is indeed curved — in four dimensions. Many people think the fourth dimension is simply time, and for some astronomical equations, it is. Einstein used time as a fourth dimension to describe a coordinate system called...

Is it possible to bend space? “We know that space can be bent. If space can be bent by, say, gravity, then spacetime can be bent,” Beacham said. To clarify, space is the three-dimensional body in which all things in the...

What is meant by bending space? Curved space often refers to a spatial geometry which is not “flat”, where a flat space is described by Euclidean geometry. Curved spaces can generally be described by Riemannian geometry though some simple cases can...
