A Christmas Visitor?

December 16, 2017
The astronomy community has been buzzing this week with discussions of a new object that has been seen in the solar system.  Its formal name is A2017UI (with the proposed common name Oumuamua, which is Hawaiian for "messenger from the distant past" ), and it is assumed to be an asteroid - but one such as we have never seen before. 

First off, it has entered the solar system from deep space, making it the first such asteroid in recent history to do so. Being extra-solar already makes it a valua...

The Trouble With Strings

November 21, 2017
Let me begin by saying that I believe that the popularization of science in general and physics in particular is a very good thing. The more educated a society becomes, the more it is able to function and advance. And in the internet age in which false information is able to spread so rapidly, it is more important than ever for trained, professional scientists such as myself to promote skepticism and rational thought, and to try to communicate what is accepted scientific fact from superstitio...

Angry Aliens?

November 17, 2017
Since mankind first looked up at the night sky, one of the biggest questions has been "Are we alone in the Universe?". Philosophers and theologians have debated this issue for centuries, while astronomers and astrobiologists continue to look for evidence and explore the data. When NASA sent probes to the edge of our solar system and beyond, they included information on our location in the galaxy and our culture in case other life forms one day discover them. Projects such as SETI have spent d...

Dark Stars

November 6, 2017
In my previous article I discussed the possibility that the Universe contains a strange type of star called a Planck star, which is prevented from collapsing due to the effects of quantum gravity. However they are not the only type of exotic star which may exist, and certainly not the only kind that can be searched for with modern telescopes.

Another interesting possibility that is being studied by the theoretical physics community is the dark star

Before I go into details though, I must clar...

Planck Stars

November 4, 2017
For most of us, our first experience with astronomy is looking up at the stars. Whether it is a prehistoric humanoid or a child living in a major metropolis, at some point we have all looked at the night sky and wondered at the distant point of light. As a result you would think that we know everything that there is to know about stars, but we do not.

Recently the theoretical physics community has started discussing a new type, called a Planck Star. At the moment it is a very theoretical and s...

A Cosmic Collision

October 17, 2017
There was an interesting joint announcement today from the LIGO, Virgo, and Fermi telescope teams, and one that will have great value to the astrophysics community. For the first time, all three simultaneously detected a neutron star collision and were able to collect data regarding both its gravitational wave signature and its gamma-ray signature. This new data will provide for interesting new studies on the physics of neutron stars and on the origin of several heavier elements in the Univer...

And The Prize Goes To...

October 3, 2017
The 2017 Nobel Prize in physics was announced today, and as expected it was awarded to Rainer Weiss, Barry Barish, and Kip Thorne their work in developing the LIGO experiment that recently made the first detection of a gravitational wave. The experiment itself was an amazing piece of engineering, and its ability to detect and study gravitational waves is going to make it a very important tool in the future for understanding the Universe.

Just over a century ago Einstein published the general t...

Nobel Predictions 2017

October 3, 2017
Once again we are at the most important week of the year for the scientific community, the week of the Nobel Prize announcements. This year there are a few serious contenders for the physics prize, and they all involve very interesting fields of research.

The leading candidate for the prize this year is probably the LIGO experiment, which last year detected the first gravitational waves. Since then they have confirmed the detection with two more gravitational waves and just recently detected t...
