<p>Scientists have pounced upon a scary theory according to which the universe shouldn't exist at all, and neither should we. In their quest to learn about how everything came into existence, several scientific models are created. They are based on hints and clues we find in the cosmos and man's understanding of it. It's all maths and physics and is bound to keep evolving with new pieces added to it. A study has challenged several such models saying that if most of them were true, the universe should have annihilated a long time ago.&nbsp;</p>

<p>They base their research on primordial black holes and the Higgs boson particle. Why do we exist? The answer can largely be attributed to the existence of the Higgs field. Similar to electricity or magnetism, this field gives everything mass. So if it weren't to exist, we wouldn't exist. But, experts say that it is not at its "lowest possible energy state", and if it fell to its lowest point "it would alter the laws of physics dramatically.”</p>

<p>Lucien Heurtier, a researcher on the study, in an article for The Conversation says, "The Higgs field isn’t likely to be in the lowest possible energy state it could be in. That means it could theoretically change its state, dropping to a lower energy state in a certain location. If that happened, however, it would alter the laws of physics dramatically.”</p>

<p>If this happens, little “bubbles” of space will form which won't conform to current laws of physics. “In such a bubble, the mass of electrons would suddenly change, and so would its interactions with other particles.

<h2>The problem with&nbsp;primordial black holes</h2>

<p>The problem with existing models arises when primordial black holes are taken into consideration. They are hypothetical objects much smaller than current black holes. As per current theories, they formed in the second right after the Big Bang and without a supernova because of extremely dense regions in the universe that likely collapsed in on themselves.&nbsp;</p>

<p>Current models say that these black holes evaporated quickly, but according to Heurtier and his team, they would have had a massive effect on the Higgs field. They say if primordial black holes ever existed, there would have been tiny bubbles everywhere. So many of these bubbles would have existed that the study says nothing should have ever formed. So if all the current models are true, the universe would have annihilated itself.</p>

<p>The study says cites two reasons. One, that all models are wrong and that primordial black holes never existed, since we know that the Higgs field is present.
