If your rationale is correct how was the mass accommodated? What changes are there to the density of the oil or the amount of force at the opposite piston?

We know that in the centre of stars matter becomes so condensed that the electron shells disintegrate so that mass becomes degenerate matter, similar reactions occur within a black hole. So although you would not notice anything as Chronos said the rest of the universe would appear pretty...

No only the twin who is actually moving will age slower, an easy way to imagine this is that the square of your velocity in space plus the square of your velocity in time will equal the square of the speed of light. I know you didn't want maths but this is very basic. Time velocity2 +...

The first thing you have to decide is what is "overweight", heavy does not always mean overweight, if your body mass index is high but your fat percentage is low (say like a body builder) that is fine but if fat levels, insulin, colesterol or antigens are not within normal limits it could mean...

Even if it does run continually it is not perpetual motion, you are driving with electricity. That is no different to putting electricity into an electric motor.

The trouble with understanding time is that people can only see entropy. Entropy is the way that things move from order to disorder, they spread out, run down, wear out all these are symptoms of entropy. New things always become old, we cannot buy old goods and see them become new as we use...

Even better look up exercises involving three body dynamics or the Trojan planets, the planets that revolve in Jupiter's orbit, held in place by the balance between the gravity of Jupiter and the sun. Depending on the size of the various bodies there is a point in an orbit where objects can be...

If the moon were as large as the Earth it would no longer be a moon but a planet in its own right. The Suns gravity would have a far greater effect on it than could the Earth. Remember gravitational force is inversely proportional to the square of the distance. If it were close enough for the...

"The longer I live, the more I realize the impact of attitude on life. Attitude, to me, is more important than facts. It is more important than the past, than education, than money, than circumstances, than failures, than successes, than what other people think or say or do. It is more important...

I don't think anyone is truly not likeable, someone somewhere will like them. You can't expect everyone to like everyone and as you go through life some will like you some won't it works the same for everyone. If someone is trying to do good and others suspect their motives my suggestion is...

Fire is not really matter, what you see when you look at a fire is a chemical reaction of matter converting from a solid to a gas e.g. wood to carbon dioxide and the release of chemical (electromagnetic) energy converted to heat and light.

A Bose-Einstein Condensate can slow the passage of light. It does not actually affect light the way a gravitational field generates a redshift it is more a matter of the super dense material adsorbs and re-emits photons in such a way that the photons entering on one side take far longer to...

We should also remember that velocity is calculated V=d/t so that to agree on velocity we must also be using similar measures of distance and time. Small variations express themselves as variations in wavelength etc but it is sometimes interesting to think about large variations for instance if...

I am still with Mach, my trouble is the figures don't quite support my hypothesis (YET). If the universe is expanding then its overall density is decreasing this has to mean a decrease in the universe's gravity, it also means that time must accelerate. Can anyone work out how we operate a...

The redshift is not the only reason that we know the universe is expanding. When Albert Einstein worked out Relativity and predicted how gravity works his calcultions indicated that the universe must be expanding, he didn't believe it was and so adjusted his calculations to compensate. It was...
