Will America fall?

Over the past few years America has been declining in their economy and in population. Now that the markets have dropped to nothing but crap the economy has fallen and will not recover. The people who suffer from this is mostly the real estate and other business companies. Sometime in 2005 the president signed a bill that will erase the borders of mexico to make some kind of freeway or somthing there without the congressess concern. Also somewhere this year or 2009 the oil will cost $200 a barell and there will also be food riots and I also heared that the US will change the dollar unit to ameros like europe and their euros. The value of the dollar here is 2 cents under the canadian dollars. So now we are not the richest country in our continent. So what do you think will america fall?

Is this why time speeds up as we age?

We take fewer mental pictures per second.

Mind & Brain
  • Recent memories run in our brains like sped-up old movies.
  • In childhood, we capture images in our memory much more quickly.
  • The complexities of grownup neural pathways are no match for the direct routes of young brains.

New alternative to Trump's wall would create jobs, renewable energy, and increase border security

A consortium of scientists and engineers have proposed that the U.S. and Mexico build a series of guarded solar, wind, natural gas and desalination facilities along the entirety of the border.

Politics & Current Affairs
  • The proposal was recently presented to several U.S. members of Congress.
  • The plan still calls for border security, considering all of the facilities along the border would be guarded and connected by physical barriers.
  • It's undoubtedly an expensive and complicated proposal, but the team argues that border regions are ideal spots for wind and solar energy, and that they could use the jobs and fresh water the energy park would create.

Why are so many objects in space shaped like discs?

It's one of the most consistent patterns in the unviverse. What causes it?

Videos
  • Spinning discs are everywhere – just look at our solar system, the rings of Saturn, and all the spiral galaxies in the universe.
  • Spinning discs are the result of two things: The force of gravity and a phenomenon in physics called the conservation of angular momentum.
  • Gravity brings matter together; the closer the matter gets, the more it accelerates – much like an ice skater who spins faster and faster the closer their arms get to their body. Then, this spinning cloud collapses due to up and down and diagonal collisions that cancel each other out until the only motion they have in common is the spin – and voila: A flat disc.
