Interesting Physics Facts

Since i missed last weeks blog, i thought i'd entertain the masses by posting a few very interesting physics facts!

If the Sun were made of bananas, it would be just as hot. If, instead of hydrogen, you got a billion billion billion tons of bananas and hung it in space, it would create just as much pressure, and therefore just as high a temperature. So it would make very little difference to the heat whether you made the Sun out of hydrogen, or bananas, or patio furniture.

All the matter that makes up the human race could fit in a sugar cube. Atoms are 99.9999999999999 per cent empty space. Now make a fist. If you forced all the atoms together, removing the space between them, crushing them down so all the vast emptiness were compressed into the fist-sized nuclei, a single teaspoon or sugar cube of the resulting mass would weigh five billion tons; about ten times the weight of all the humans who are currently alive.

The faster you move, the heavier you get. Light speed is the speed limit of the universe. So if something is travelling close to the speed of light, and you give it a push, it can’t go very much faster. But you’ve given it extra energy, and that energy has to go somewhere.Where it goes is mass. According to relativity, mass and energy are equivalent. So the more energy you put in, the greater the mass becomes. This is negligible at human speeds . In several experiments, objects accelerated to 86 percent of the speed of light have doubled in weight. The theory also postulates the rather incomprehensible notion that given enough speed, an object will become as large as the universe itself.

Always your,
