Prejith asked:
What is space time?
Ans:
In order to describe an event, we need to specify its position in space and the time of occurrence. A four-dimensional continuum with the three co ordinates of space and time as the fourth co ordinate is called space-time.

Can you say What’s This?
just like the pic shows & the chat above gives the idea of 4-D as a penalty of reflection !!
Joining the edges of the crystal cube to the edges of its reflection in light causes an image which is the pic depicted above … which is rotated & shown , & so some say 4-D is the dimension caused due to pealty of reflection !!!!
u never know cause we r trapped in this 3-D world !!!
