We Know How Complex Cells Evolved
Complex cells (eukaryotes) likely evolved from single-celled organisms (prokaryotes) absorbing other prokaryotes, becoming single complex cells over time (endosymbiosis).
Natural and Physical Sciences
A broad category referring to the study of the physical universe including nature and biology.
The Universe is Mostly Empty Space
The universe and everything in it, including humans, is mostly “empty space.” However, space is not actually “empty,” it’s filled with quantum fields and dark energy.
Energy is Neither Created or Destroyed
Energy can’t be created or destroyed and neither can mass. Although energy can change forms, all energy in a closed system must remain constant.
All Fruits Come From Flowers
All fruits come from flowers, but not all flowers become fruits. Fruits are typically derived from the ovaries of a flower and contain seeds.
Things Can Actually Touch Each Other
Things never touch because everything is made of atoms. Atoms contain electrons and electrons repel each other. This is basic physics.
Eating Tomatoes Helps Prevent Sunburn
Tomatoes contain lycopene, which may help protect your skin from UV damage, this means eating tomatoes may work as a natural sunblock to prevent sunburn.
Astrology and Astronomy are the Same
Astronomy is a science that studies celestial objects and the physical universe. Astrology is a pseudoscience that studies celestial objects to predict events.
Humans Only Use a Small Part of Their Brain
Evidence suggests that humans use virtually every part of their brain on a daily basis. Some areas function more than others at any given time, but every part of the human brain has a function.
Time is Relative
Time is relative to speed and gravity (time dilation), and so is space (length contraction). Light speed is constant for all observers, so time and space can’t be.
Galileo Invented the Telescope
The telescope is credited to Hans Lippershey in 1608. The following year Italian astronomer Galileo Galilei began making improvements to its design.
