Is there evidence to rule out the possibility that dark energy is not a positive force inside our universe, but rather caused by a negative force created by a perfect vacuum outside? I understand there is no such thing as a perfect vacuum inside our universe, manmade or otherwise. But, if there were a perfect vacuum outside, I can imagine it would be like a balloon expanding, finding itself suddenly on the Moon. If we were inside this balloon, might we wonder just what positive force was pushing on the sides of the balloon, rather than a force pulling from outside? Does the math rule this out? I'm ignorant.

With all the handwringing concerning what we should do if a large asteroid threatens Earth, I have a pretty simple idea. Embarrassingly simple. The Japanese have already demonstrated we have the technology to land a spacecraft on an asteroid, so, we land one or more relatively small spacecraft on the asteroid, rotate the landing engines 180 degrees, fire them up, and literally push the asteroid into another trajectory. Please spell my name correctly on the check, Mankind.

We have no idea how gigantic the star might have been in another dimension that collapsed and created our Big Bang, but that's my theory, as well. It's called a 'white hole'. Gravity would not have pulled everything back immediately because gravity spreads out into 9 dimensions, not just three. Terribly, terribly weak, compared to the other three forces. When a star collapses to form a supermassive black hole, the fabric separating our three dimensions from others is torn and the material is filling up the 'space', maybe a millimeter away from us, yet undetectable, except for the effects of its gravity. I predict if we use gravitational lensing to determine sizes of dark matter clumps around our galaxies, then we will see that, as the black hole swallows material, the 'surrounding' dark matter clumps will grow. The dark matter scaffolding wasn't already there to create galaxies, but, rather, the 'scaffolding' is being created by dark matter, the gravity of which is maintaining stars in orbits around the black hole. Remember the mysterious light that appeared in the heavens light years away that slowly grew, before shrinking and disappearing? That was a star collapsing from another dimension into ours, spilling its star stuff into our Universe. I have a high school education, so blast away.
