humans will last about 1 second once the sun rays reaches us from the sun blowing up

Not true. Our sun will become a red giant when it runs out of hydrogen and starts "burning" helium. When it does its radius will expand to well beyond the earth's orbit. So the earth will be a burnt-out cinder much before the end of sunlight.
"the longest you can live without the sun is 1 hour" - What the first guy wrote... This is wrong... first of all, nighttime is is at least 8 hours long... and I'm not dead
The electric light bulb as you know it today was first tested on October 22, 1879 by Thomas Edison and it lasted 13.5 hours.
In an ordinary house, it would be difficult to live more than a month, because of the extreme cold.
It has been around for 270 years and 95 days
A human can basically go three months without shelter.
I don't think the first one burned at all. It exploded.
Evolution has resulted in humans being creatures that are active in daytime. Therefore for as long as there have been humans hey have used light (daylight).
ever since gooses roamed the earth

We use natural light to see. Amplified light can be used in lasers which can transmit enough energy to cut materials including metal. Optical fibers are increasingly used to transmit digital data, rather than metal conductors.
I looked it up in my physics text book and it says that the wavelength is too long to be seen by the human eye.
They can. While human eyes can not "see" infrared light, humans can detect this light as "heat" on the surface of the skin.
normal band of light
Only with a really light surfboard.
Oxygen
a very long time.
To humans RED means stop or danger in our brains.

"used cats" cats arent drug!!
light is very help ful to humans because humans need light to see dark and humans need light so they can do their work. that's all i think
it was used in 18816

Light is what humans process faster
NO, HUMANS CAN SEE LIGHT BETWEEN THE WAVELENTHS OF VIOLET AND RED. HUMANS CANNOT SEE ULTRAVIOLET OR INFRARED LIGHT.
