When you first start learning about black holes, the mind truly boggles, and the maddening, tantalizing thing about them is the more you grow to understand them, the less you feel you know. Still a mystery to the world’s greatest scientific and mathematical minds, until an entirely new theory is dreamed up that accounts for …
We often hear the phrase, faster than the speed of light, thanks to Queen, no doubt. Our old science lessons in school way back when and pop lyrics allow us to remember how fast light travels, saving us shame on a pub quiz. But what about gravity? In every part of our lives, it is …
Though it may seem like an unusual question, what would happen if you were driving your car at nearly the speed of light and you turned on your headlights. It’s not likely something that will ever happen, but what if? Light, travels at the speed of light, obviously. But what if you were to turn on …

Both of these belief systems would be …
Do you realize that if you fall into a black hole, you will see the entire future of the universe unfold in front of you in a matter of moments and you will emerge into another space-time created by the singularity of the black hole you just fell into? – Neil DeGrasse TysonOnce thought to …

Gravity is a natural phenomenon, thanks to which all things with a mass or energy are brought toward one another. On Earth, we see gravity as the force that makes everything fall back down to the ground, but that’s because the planet itself has a huge mass and energy, so everything is dragged towards it. But …
Does the Influence of Gravity Extend Out Forever? Read More »
Gravity is a vital force in the universe. Every single object in space has a gravitational pull, and so gravity is a force that works to influence the paths and direction of every single thing travelling through space. If gravity works to pull everything and all objects, you may be wondering how this works in …

In August of the year 2006, an official statement from the International Astronomical Union caused a stir throughout the astronomical community and the world at large. Pluto, the IAU declared, was being downgraded in status from ‘Planet’ to ‘Dwarf Planet.’ Our solar system, as we know it, would now consist of 8 planets rather than 9. The …
This is a question that has a bit of weight to it, and there is no straightforward answer to it. There is an up and down in space, but perhaps not in the way that you might expect. As you have probably guessed, being in space and being on Earth are both very different experiences, …
