Misconceptions About the Universe

Can we see things travelling faster than light?

The expanding universe is a complicated place. During inflation the universe expanded faster than light, but that’s something that actually happens all the time, it’s happening right now. This doesn’t violate Einstein’s theory of relativity since nothing is moving through space faster than light, it’s just that space itself is expanding such that far away objects are receding rapidly from each other.

Common sense would dictate that objects moving away from us faster than light should be invisible, but they aren’t. This is because light can travel from regions of space which are superluminal relative to us into regions that are subluminal. So our observable universe is bigger than our Hubble sphere – it’s limited by the particle horizon, the distance light could travel to us since the beginning of time as we know it.

10 Discoveries Unexplained By Science

Impossible planets, mysterious noises from the deep, and inexplicable artifacts buried for centuries, there are some things even the smartest of scientists struggle to explain. Take a look at the ten most baffling discoveries.

SCIENCE! 100 lbs (45 kg) of Magnetic Putty

We’ve been selling Magnetic Thinking Putty for years and have always been astounded by the burning questions we’ve received for this ever-popular item.

So, we decided to do some experimentation utilizing a 100-pound ball of Magnetic Thinking Putty and a ridiculously strong magnet.

**For those of you wondering, the large magnet in the video has a pull force of approximately 720 lbs!

Living With Lag - An Oculus Rift Experiment

You wouldn’t accept lag offline, so why do it online?

ume.net, a fiber broadband provider that offers up to 1000 Mbit/s, performed an experiment. Four volunteers got to experience internet’s biggest disturbance in real life - lag.
