Are you Sitting Comfortably? The Universe is about to End!

Are you Sitting Comfortably? The Universe is about to End!

Well we may all be congratulating ourselves that on 21 December last year the world didn’t end, but whereas the end of the Mayan calendar didn’t wink us out of existence, the reversing of the Big Bang may. And it could be happening sooner than you think.

It’s been long thought that the expansion of the universe that took place after the Big Bang (with the red shift effect- everything moving away from everything else) was slowing down and would eventually stop. And then go into reverse, contracting back to a central point when another Big Bang might occur.


It used to be thought that this scenario would happen millions of years hence, but physicists now say it could happen sooner rather than later. It’s a team at the University of Southern Denmark that have calculated that a universal “phase transition” could start at any point after every particle in existence becomes “extremely heavy”.


It’s all rather complicated and involves the Higgs Boson “God” particle- the one that gives matter mass, shifts to a lower vale than before making all elementary particles inside the field becoming super-heavy and causing as chain reaction that would pull apart the universe at the seams.

Let’s hear from Jens Frederik Colding at the University’s Centre for Cosmology and Particle Physics Phenomenology:

“Many theories and calculations predict such a phase transition– but there have been some uncertainties in the previous calculations. Now we have performed more precise calculations, and we see two things: Yes, the universe will probably collapse, and: A collapse is even more likely than the old calculations predicted. The phase transition will start somewhere in the universe and spread from there. Maybe the collapse has already started somewhere in the universe and right now it is eating its way into the rest of the universe. Maybe a collapse is starting right now right here. Or maybe it will start far away from here in a billion years.”


Hardly precise measurements- no need to cancel getting next year’s diary. And there are counter arguments. Some scientists say there may be other undiscovered particles in the universe that would prevent this reaction occurring. So in summary, business as usual. Probably.

Methuselah Star is Older than the Big Bang?

Methuselah Star is Older than the Big Bang?

Methuselah, according to the Bible, lived to a ripe old age of 969.  Methuselah, the star, formally known as HD 140283,  is somewhat older.  Scientists say that according to their calculations, it is between 14 and 15 billion years old.  That not only makes it the oldest object currently known to astronomers, but also pre-dates the Big bang and the birth of the universe, which came about 13.8 billion years ago.

Even more strange, the star is on our own doorstep – a mere190 light years away, and inside our galaxy.  There is, however a margin of error in the calculations of 800 million years- so it could just about get in there for the birth of the Big Bang. The team from Pennsylvania State University and the Space Telescope Science Institute in Baltimore are re-checking their calculations and observations, and therefore a more accurate figure may come later.

Methuselah Star is Older than the Big Bang?

The star was first discovered a hundred years ago, and is moving more than 800,000 mph away from our solar system.

These calculations will ignite the debate about whether anything existed prior to the Big Bang.
