5 Science Trivia Questions to Get You Thinking

[downbeatplumb]

1. How can the universe be 93 billion light years in diameter when the big bang was only 13 billion years ago? Can dark energy cause regular matter to move faster than the speed of light?
2. In relation to the orbit of the sun around the center of the galaxy, is the orbit of the Earth around the sun perpendicular or parallel?
3. Do all the planets orbit the sun on the same p lane, i.e., around the equator of the sun at the same angle
4. Why if it we can’t drink sea water, but we can eat sea salt??
5.    According to one website,   dark energy is made of neutrinos. If we know what it's made of why do we still call it dark?


Happy thinking!

1. How can the universe be 93 billion light years in diameter when the big bang was only 13 billion years ago? Can dark energy cause regular matter to move faster than the speed of light?

because of two things the initial expansion/inflation was enormous and fast and the universe continues to expand like a balloon.
 
2. In relation to the orbit of the sun around the center of the galaxy, is the orbit of the Earth around the sun perpendicular or parallel?

3. Do all the planets orbit the sun on the same p lane, i.e., around the equator of the sun at the same angle

not quite all but mostly they orbit in the same plane. Pluto orbits in a strange loop.


4. Why if it we can’t drink sea water, but we can eat sea salt??

You can drink sea water but not very much of it because of osmosis it would actually dehydrate your body. If you were to eat loads of sea salt it would not do you any good for the same reason.
 
5.    According to one website,   dark energy is made of neutrinos. If we know what it's made of why do we still call it dark?

We don't know its neutrinos.

In physical cosmology and astronomy, dark energy is an unknown form of energy that affects the universe on the largest scales. The first observational evidence for its existence came from supernovae measurements, which showed that the universe does not expand at a constant rate; rather, the expansion of the universe is accelerating.
