Will humans survive mass extinction? We’re so uniquely adaptable, we might even survive a mass extinction event. Given a decade of warning before an asteroid strike, humans could probably stockpile enough food to survive years of cold and darkness, saving much or most of the population. How did animals survive mass extinction? “It was the […]
What happens when two galaxies approach each other?
What happens when two galaxies approach each other? When galaxies merge, the gasses interact with each other. As they begin to approach one another, the galaxies begin to stretch and deform, creating tails or arms. The combination of the two galaxies then forms what appears to be an elliptical galaxy as the arms begin to […]

What is maximum data rate of channel?
What is maximum data rate of channel? Higher data rates are expressed as Kbps (“Kilo” bits per second, i.e.1000 bps), Mbps (“Mega” bits per second, i.e.1000 Kbps), Gbps (“Giga” bits per second, i.e. 1000 Mbps) and Tbps (“Tera” bits per second, i.e. 1000 Gbps). One of the main objectives of data communications is to increase […]

When you increase the repetitions, amount of weight, or length of time in an exercise you’re accustomed to, you’re applying overload. Which principle do you feel is […]
Is a compass needle an induced magnet?
Is a compass needle an induced magnet? The compass reacts with the earth’s poles to point in the direction of the earth’s North Pole. Rubbing the magnet against the needle in one direction caused the iron atoms in the object to line up and create a weak magnetic field, which made the needle behave like […]
