Blog 3 – The Great Collision

Right now, everything in our universe is getting further and further away from us. Except for one thing. That one thing is Andromeda, the closest galaxy to our Milky Way. Instead of getting further away, Andromeda is actually getting closer and closer. Right now, we are getting closer at a rate of 300 kilometers per … Continue reading Blog 3 – The Great Collision Continue reading Continue reading

Putting the speed of light into perspective

The theory of special relativity tells us that there is an absolute speed limit in the universe, that being the speed of light. At a speed of about 300,000 km/s, light takes only one second to travel to the Moon from Earth and eight minutes to travel to the Sun from Earth. This speed is … Continue reading “Putting the speed of light into perspective” Continue reading Continue reading

Consequences of a Constant Speed of Light

I find it fascinating that what we see in the night sky is an image from the past.  Since nothing moves faster than the speed of light it is impossible to know what is going on at this exact moment on places other than the Earth and the Moon.  Hypothetically, the Sun could suddenly explode […] Continue reading Continue reading

The Vast Size and Scale of the Universe

Recently I saw this link on Facebook and I decided to check it out. I had no idea what I was in for. We have been talking about our galaxy and our nearest neighbor, The Andromeda Galaxy, a lot in class and this picture just released by NASA gives us a better idea of what exactly […] Continue reading Continue reading

Light Travel Time and Observing Extraterrestrial Life

A topic that has really intrigued me is the speed of light and the time it takes for light to travel. The above image was taken by the Hubble Space telescope of galaxies billions of light years away. Some of these galaxies even extend back in time to only a few hundred million years of the […] Continue reading Continue reading

A TITANIC COLLISION…but not really

Collision: col·li·sion (kəˈliZHən) – noun: an instance of one moving object or person striking violently against another. Now imagine the outcome of a collision between Andromeda and the Milky Way which, according to the dictionary definition, should be a violent impact between two massive galaxies with millions of stars hurtling towards each other 2000 times faster than a […] Continue reading Continue reading

The size of the Universe

To say the Universe is big is a bit of an understatement. The monster truck parked outside is considered big, the girl sitting next to you in class is called big by some people in bated breath, the Big Mac is supposed to be big (says so in the very name). When we’re talking about […] Continue reading Continue reading
