尺寸迷思

we'll find out if the way things are is the only way they can be and explore the consequence of a world were things are bigger.Call it a thought experiment if you like ,something scientists have always used to explore the workings of the universe.

Size doesn't matter,what matter is health and overcoming obstructions.

If we can't change the size of the planet how about changing the size of life on the planet?

Even with a four legged friend life as a giant would be no fairytale.It would have to be a very strange creature indeed to overcome all the problems that being big creates for a human being.That's because size is intrinsic to everything. Your size determines what shape you are, how you live,what you eat.Change it too much and you simply get a different species.

In astronomy we have a great privilege.we can do something that historians and archaeologists only dream of, we can directly take images of the distant past and we do this by looking at objects that are far away in the universe. Objects that are far away they have sent out the light that we receive billions of years later,and light travels with a limited speed(the speed of light)and therefore looking far out into space means also looking far back into time.
