EINSTEIN'S RELATIVITY:

Everything in the universe is traveling through space-time at the speed of light - the maximum speed possible. If you are sitting still in space, then you are traveling through time at the maximum speed. But if you begin traveling through space, then your progress through time slows down. Time Dilation and other relativistic phenomena await you in this interesting series, so hurry up and slow down!

SPACE:

Want to know why we don't have to worry about our sun burning out? It's because long before that happens, the sun will expand so enormously that Earth will be cooked to a cinder. Take a tour through the solar system, learn about the event horizon of black holes and when our galaxy began.

  • @Notsorandomnumbers more on youtube in 40 minutes than 12 years of school.

  • @LesPaul2006 This is an entirely different concept. The fact that a magnet pulls an iron nail is to do with the arrangements of atoms within the magnet. Only VERY large objects such as the sun or planets can curve space-time enough to have a large impact on other objects. The mass of a magnet or a nail is far too small to be even considered for space-time curvature.

  • some sweet info here

  • brilliant video

  • love the video really good

  • @MurkyMists Well you don't need magnetism for that. It is very well explained by gravity. To add magnetism just "muddies the waters". Also magnetism can't be the force pulling everything together or as you say "sucking down" - cos not all is attracted to a magentic field, somthings are repulsed by it. And I have to say, I have never heard of a thing suddently by itself being hurled into space by reverse gravity (which it would look like if magnetism did it)

  • @BjornSeverinLarsen yup, i hear ya, just a thought, but apparently EVERYTHING has sum sort ov magnetism, even plastics, maybe stuff u dnt see in air is being sucked down by magnets n keeping everythin down with it.

  • @MurkyMists Well magnetism is created by a magnetic field. It attracts some substances and repulse others. Also there are some substances which we know aren't affected by magentism like gasses, plastic, copper and aluminium. So i would like to state my previous point, magnetism doesn't affect gas but as we see in the universe, large gas clouds are being affected by gravity. So gravity is not magnetism

  • @BjornSeverinLarsen yeh but apparently ,everything! has magnets in it or magnetic energy,maybe its magnetism from the sun, from the planets, other stars and the galaxy yu are in, leave the earths magntic field n theres no (gravity)

  • @flowiepanda coz it's awsome :)

  • @qwerty2711323 or perhaps cos we can't see them since they don't interact with light? Or just cos we haven't discovered dark matter and energy is yet. Might be called something else soon enough

  • @MurkyMists ehm no. You will still be influenced by gravity. Gravity from the sun, from the planets, other stars and the galaxy you are in. The magnetism doesn't explain gravity, cos it works the same on gas as on metal heavy planets (not magnetism but gravity). It would be impossible to float away without an equal force to the gravity effect a thing is under.
