I've been reading 'the never ending days of being dead' by Marcus Chown and he's compiled a few interesting ideas. It's lead me to think that the expansion of the universe is recorded by the universe, which causes it to expand more and record this and expand even more... in short that the universes expansion causes the universe to expand in itself.
This probably sounds confusing and or strange, but it's really not.
1. During the first few yoctoseconds, all the matter and energy began to escape from the impossibly super-dense singularity of creation. The big bang. For this to happen, time must be existent or nothing would move (infact if time never existed then nothing at all would have ever existed!) and therefore the dimension of space-time was born.
2. As something moves, it leaves a record in the relative past of it's movement.
3. As things are 'recorded' on the cosmic storyboard of the 4th dimension, space-time expands.
4. As space-time expands, things are 'recorded' on the cosmic storyboard of the 4th dimension.
5. Therefore spacetime exists for its own cause because space-time needs more space-time.
6. Therefore it expands because it expands.
7. Therefore its a reason WITHIN ITSELF.
This is exiting because one of the eternal philosophical questions is 'how can something have come from apparent nothing?', surely if nothing existed then existance would have to have a purpose within itself. It would need a REASON WITHIN ITSELF.

Artificial gravity suits
This caught my eye after adding the Popular science gadget.
Superhero-Style Spacesuits Could Provide Vital Compression For Astronauts 29 October 2010 21:49:00

Testing the Suit in Zero Gravity MIT/James Waldie
This new Spiderman-style suit may not win astronauts a spot in the fashion hall of fame, but it could help keep their bones intact during long spaceflights. Described in a new paper, prototype tests of the Gravity Loading Countermeasure Skinsuit, being developed by a research team at MIT's Man-Vehicle Laboratory, show that the suit simulates the effects of gravity on the human body, which could solve one of the biggest obstacles to future human space travel.
Astronauts lose 1 to 2 percent of their bone mass for each month they spend in space. As far back as the Gemini missions, conditioning exercise regimes have been used to slow the rate of bone loss, but a 2001-2004 NASA-sponsored study showed that crew members aboard the International Space Station (ISS) were still losing up to 2.7 percent of their interior bone material and 1.7 percent of outer hipbone material for each month they spent in space. If ISS crew members lose this much bone density after 4 to 6 months in space, astronauts on long missions to Mars-voyages that could take years-could lose enough bone mass that they suffer fractures while carrying out tasks on the Martian surface.
With stirrups that loop around the feet, the elastic gravity skinsuit is purposely cut too short for the astronaut so that it stretches when put on-pulling the wearer's shoulders towards the feet. In normal gravity conditions on Earth, a human's legs bear more weight than the torso. Because the suit's legs stretch more than the torso section, the wearer's legs are subjected to a greater force-replicating gravity effects on Earth.
The prototype suit testing took place on parabolic flights that created brief periods of weightlessness. Results showed that the suit successfully imitated the pull of gravity on the torso and thighs, but it did not exert enough force on the lower legs. Researchers are now refining the suit's design to address this; they also plan to test the suit to see how it performs when worn overnight. Volunteers who wore the suit on the test flights reported that the suit was comfortable and did not significantly restrict movement, which means crewmembers can work and exercise while wearing the suit.

Cyclic Universe Theory
I'll mention cyclic theory a few times, so here's an explanation.
Cyclic theory predicts that the current universe will end in a "big crunch" where so much matter is in existence that the gravitational force of the universe will slow its own expansion to a halt and then contract, reversing the direction of space-time (the fourth, not-fully-physical dimension). The "big crunch" is already an conceived theory, so cyclic theory predicts that the "big crunch" will be true in its own right. So what happens when the universe has crushed itself into a super dense singularity (the smallest amount of matter possible) again? Well if the entire universe were somehow contained in such a small space and all the forces with it then it would automaticaly expand with cataclysmic force, heat and speed. Another big bang. Only this time, because the entire universe was just mangled beyond recognition, everything is a little bit different.
I like this theory because it means that the teleological (design) argument for the existence of god is useless. The teleological argument says that because everything is so complicated and works so well, only god could have created it. But if a slightly different universe is created after every "big crunch", then the current universe was going to be created sooner or later and without a god.

Oscillating Universe Theory
I may also mention Oscillation theory a few times. It could be feaseable, but i'm less sure of this explanation as it's less mathematical (even though randomness can occur in mathematics.)
Oscillation theory predicts that a fifth dimension (it's uncomprehendable to us, don't worry if you cant visualise it) of vacuum acts between 'universes' and occasionally pulls them together. Imagine a flat ocean that is infinitely vast and now imagine an upside-down ocean, parallel to the first and equaly vast (floating above the first.) This leaves a strip of air between the waters and this air is the fifth dimension. But this air is a black vaccuum trying to pull the water together and this water is two multi-verses, quite close to eachother. The 'pulling' of the vacuum creates ripples and waves on the water and when the waves of the the two verticaly parallel oceans collide, it creates a huge splash of matter in the vacuum and this creates a new multi-verse.

Photo competition October 2010
Competition ends 28/2/11.
Heres an interesting topic to kick off my blog. Do you belive in a multi-verse as opposed to a solitary universe and why?
Is a single "universe" the answer as posed by the big bang? well according to new theories on creation, such as the oscillating universe and cyclic universe theories, the big bang is wrong.
