FFD is an awesome game but there was a lot of obstacles to pass before i can play the game.so many obstacles that i do not want to write them down.anyway,its another boring day,so....i think i will sleep later and its wasting my life away.but at least its better than yesterday.i had this weird dream last night.i was dreaming about this multi-coloured alien who was dying and telling a reporter from USA i think,about the secrets of how human beings were created and the mysteries of black holes...oh yes,i forgot to mention that they were in a big pyramid and the alien was lying on a rectangular piece of rock.which basically looked like a table with ancient egyptian writings.it was dark and the only light was the fuel lamp which the reporter brought.and when the alien died it became a carved picture on the table with ancient writings.after the alien died then i realised i was watching the show on youtube...weird dream isn't it?anyway this is the end of the post

Theories about the end of universe
Big Freeze or Heat Death
Main article: Future of an expanding universe
The Big Freeze is a scenario under which continued expansion results in a universe that is too cold to sustain life. It could, in the absence of dark energy, occur only under a flat or hyperbolic geometry. With a positive cosmological constant, it could also occur in a closed universe. A related scenario is Heat Death, which states that the universe goes to a state of maximum entropy in which everything is evenly distributed, and there are no gradients — which are needed to sustain information processing, one form of which is life. The Heat Death scenario is compatible with any of the three spatial models, but requires that the universe reach an eventual temperature minimum.
[edit] Big Rip: Finite Lifespan
Main article: Big Rip
In the special case of phantom dark energy, which has even more negative pressure than a simple cosmological constant, the density of dark energy increases with time, causing the rate of acceleration to increase, leading to a steady increase in the Hubble constant. As a result, all material objects in the universe, starting with galaxies and eventually (in a finite time) all life forms, no matter how small, will disintegrate into unbound elementary particles and radiation, ripped apart by the phantom energy force and shooting apart from each other. The end state of the universe is a singularity, as the dark energy density and expansion rate becomes infinite. For a possible timeline based on current physical theories, see 1 E19 s and more.
[edit] Big Crunch
The Big Crunch. The vertical axis can be considered as either plus or minus time.
Main article: Big Crunch
The Big Crunch theory is a symmetric view of the ultimate fate of the universe. Just as the Big Bang started a cosmological expansion, this theory postulates that the average density of the universe is enough to stop its expansion and begin contracting. The end result is unknown; a simple extrapolation would have all the matter and space-time in the universe collapse into a dimensionless singularity, but at these scales unknown quantum effects need to be considered (See Quantum gravity).
This scenario allows the Big Bang to have been immediately preceded by the Big Crunch of a preceding universe. If this occurs repeatedly, we have an oscillatory universe. The universe could then consist of an infinite sequence of finite universes, each finite universe ending with a Big Crunch that is also the Big Bang of the next universe. Theoretically, the oscillating universe could not be reconciled with the second law of thermodynamics: entropy would build up from oscillation to oscillation and cause heat death. Other measurements suggested the universe is not closed. These arguments caused cosmologists to abandon the oscillating universe model. A somewhat similar idea is embraced by the cyclic model, but this idea evades heat death, because of an expansion of the branes that dilutes entropy accumulated in the previous cycle.
[edit] Big Bounce
Main article: Big Bounce
The Big Bounce is a theorized scientific model related to the beginning of the known Universe. It derives from the oscillatory universe or cyclic repetition interpretation of the Big Bang where the first cosmological event was the result of the collapse of a previous universe.
According to one version of the Big Bang theory of cosmology, in the beginning the universe had infinite density. Such a description seems to be at odds with everything else in physics, and especially quantum mechanics and its uncertainty principle.[citation needed] It is not surprising, therefore, that quantum mechanics has given rise to an alternative version of the Big Bang theory. Also, if the universe is closed, this theory would predict that once this universe collapses it will spawn another universe in an event similar to the Big Bang after a universal singularity is reached or a repulsive quantum force causes re-expansion.
[edit] Multiverse: no complete end
Main article: Multiverse
The multiverse hypothesis states that our universe is but one universe among infinite parallel universes, possibly with different physical laws. Whatever the ultimate fate of our universe may be, almost all parallel universes will have different fates. And while many universes may be closed, many others may be open. The multiverse as a whole may never end completely.
[edit] False vacuum
If the vacuum is not in its lowest energy state (a false vacuum), it could tunnel into a lower energy state.[citation needed] This is called the vacuum metastability event. This has the potential to fundamentally alter our universe; in more audacious scenarios even the various physical constants could have different values, severely affecting the foundations of matter, energy, and spacetime. It is also possible that all structures will be destroyed instantaneously, without any forewarning.
[edit] Many-worlds interpretation of quantum mechanics
According to the many-worlds interpretation of quantum mechanics, the universe will not end this way. Instead, each time a quantum event happens that causes the universe to decay from a false vacuum to a true vacuum state, the universe splits into several new worlds. In some of the new worlds the universe decays; in some others the universe continues as before.
[edit] Cosmic uncertainty
Each possibility described so far is based on very simple form for the dark energy equation of state. But as the name is meant to imply, we know almost nothing of the real physics of the dark energy. If the theory of inflation is true, the universe went through an episode dominated by a different form of dark energy in the first moments of the big bang; but inflation ended, indicating an equation of state much more complicated than those assumed so far for present-day dark energy. It is possible that the dark energy equation of state could change again resulting in an event that would have consequences which are extremely difficult to parametrize or predict.

The solar wind is a stream of charged particles —a plasma—ejected from the upper atmosphere of the sun. It consists mostly of electrons and protons with energies of about 1 keV. These particles are able to escape the sun's gravity, in part because of the high temperature of the corona, but also because of high kinetic energy that particles gain through a process that is not well-understood at this time.
The solar wind creates the Heliosphere, a vast bubble in the interstellar medium surrounding the solar system. Other phenomena include geomagnetic storms that can knock out power grids on Earth, the aurorae such as the Northern Lights, and the plasma tails of comets that always point away from the sun.

went to regent today because wayne had to carry his percussion instruments.then we realised that his instruments wasn't there.then we waited for siang joo and the rest to go home and we went to siang joo's house to play monopoly. but we didn't really play monopoly over there,we played wayne i played psp instead. leonard,sean and arshad went too. then wayne and i went to gym while arshad,sean and leonard head home.we arrived late glad to see that my shoulder muscles are better than before:)but my biceps and triceps have no improvement at all:(gotta train more.an chun,jerrick and jackson were there too.but when we arrived they were about to leave...so wayne and i went to train while they went back.then we saw this malay guy whose biceps was very disgusting.about 15 cm bigger than an chun's.then after the training ,we went to the nearest coffee shop to eat half boiled eggs.wayne and i ate two each.wayne said he was hungry and went to hougang mall's kfc to eat.i wasnt very hungry and waited for him to finish.but i went home early because i was tired and wanted to sleep.so i will end my post here cos i wanna sleep.
