"At some point, the gluons will no longer be able to hold the quarks together, and the hadrons will decay. Which will mean the end of matter in this universe." - Albert Einstein  1 As it seems, in our universe, nothing is made to last. Eventually, everything gets old and dies or changes or decays into something else, and I am not referring to the life forms only but all matter in the cosmos. For all we know, this might not be true within our own macroworld alone, but also deep below, the same goes for particles in the quantum realm as well. The fact is that everything in the universe has a tendency to achieve the lowest energy state and to finally rest within a stable system, even if that means going through various changes or decays. In the quantum world, this could be true for the Higgs field as well. According to Hawking, if it becomes meta-stable, the vacuum decay bubble will emerge and consume everything in order to eventually reach the lowest energy state possible. F...

Don't take this title too seriously. It's wrong on multiple levels. Grammatically and scientifically. Nonetheless it fits perfectly for this post. As for grammar amiss - I used Latin root word 'Gravis' which means heavy and it is actually perfect adjective for gravity as we perceive it here on Earth. As for scientific issue, the rest of the title might be all wrong. If we glimpse into features of three main natural forces of the universe, it is obvious that they work in more or less the same fashion - they use carriers or elementary particles to mediate the force through the force field. Photon is one of them and it carries electromagnetism while strong and weak force in nucleus respectively are mediated by gluons and w/z bosons and they are all confirmed in experiments. Gravitons suppose to be the same thing for gravitation force, but they are never found and confirmed either directly or consequently. Ever since Einstein we are having second thoughts about whether or ...

It's a well known fact that our universe is, as far as we know today, four dimensional space-time continuum with three spacial coordinates and the time playing a role of the fourth one. We are perfectly capable of traveling backwards and forwards within first three spatial coordinates, but is it possible to do the same on the fourth one? I am sure you would agree that it is not too exciting going up or down or left or right but traveling through time could be something special. But, is it possible? Let's explore all the theories, share some stories and read about one connected hoax.

Did you know that if you were standing on the near side of the Moon, and for your mass of 80kg and weight of 785N on Earth, due to Moon's lower gravity, you would not feel being heavier than 13kg (130N)? You knew? Ok, did you know that Earth's and Moon's gravities combined gave you different weight on near and far side of the Moon? Slightly yes, but true. Earth and Moon are relatively small celestial bodies but this difference goes even higher if you move from the Moon to the Io or Europe for example as they are also tidally locked by Jupiter just like our Moon is locked by Earth. This would most definitely not help mountains on Avatar's Pandora to float but still, within right conditions and with presence of large mass(es) nearby, considering appropriate composition of the ground I am sure there are solar systems out there with strange conditions to live with, to say the least.
