Can you see light if not why?
You can see the light which enters in your eye and is absorbed by your retina. So you cannotsee the light passing by because it is not going towards your eye. If it meets an object, however, light will be reflected or scattered and part of it will go towards your eye. Most objects do not reflect light.

What is a shadow for kids?

How are tides caused?
The moon’s gravity pulls the ocean toward it during high high tides. During low high tides, the Earth itself is pulled slightly toward the moon, creating high tides on the opposite side of the planet. Earth’s rotation and the gravitational pull of the sun and moon create tides on our planet.
How shadows are from in space?
Light streams through gaps in the ring, creating the brilliant cone-shaped rays. However, denser patches in the disc block some of the light, casting long, dark shadows through the galaxy.
