The universal speed limit is 299,792,458 metres or 300,000 kilometres per second, and due to the rules the flying spaghetti monster imposed upon the universe during its creation, this limit cannot be broken.

Why Are There As Many Males As Females?

Evolution doesn’t pick a side! Don’t miss our next video! SUBSCRIBE! ►► http://bit.ly/iotbs_sub ↓↓↓ More info and sources below ↓↓↓ In almost every animal species on Earth, equal numbers of males and females are conceived. Why is that?

It turns out that in most cases, an equal balance of the sexes is the evolutionary stable strategy. From Charles Darwin to Ronald Fisher to W.D.

The Meaning of Colors for a Spiritual Seeker | Sadhguru

Sadhguru explains the nature of color, and looks at how some chakras are connected with certain colors. He also explains how a spiritual seeker can use certain colors to their benefit, depending on their situation and path. Those on a path where they do not wish to gather anything, wear white. If someone's sadhana is intense and oriented towards the agna chakra, they wear orange. He also explains why Buddhist monks initially wore yellow robes, and why they later switched to maroon. **************************************** Transcript: http://isha.sadhguru.org/blog/video/meaning-of-colors-for-spiritual-seeker/ Sadhguru: Now, the color of the clothes or the colors of anything around you, does it have some...
