Breathtaking impact craters | WhatPoll? Meteor Crater, sometimes referred to as Barringer Crater, after Daniel Barringer, the geologist who was first to propose the crater was formed by the impact of meteorite, is located 43 miles east of Flagstaff, Arizona. Although small compared to other impact craters in the solar system with a diameter of around 1.1km, it is a truly breathtaking site to cast your eyes upon. Situated in the middle of the desert, and produced 40,000 years ago by a nickel-iron meteorite travelling from somewhere between 28,000 and 45,000mph, the impact would have been nothing short of spectacular to have witnessed when it occured. Interestingly, at the time of impact, the surrounding Colorado Plateau was experiencing the end of the Pleistocene epoch, which meant the local ecology was covered in mostly grassland, and paraded by mammoths and camels.

How a slight tap could literally knock down The Empire State Building Here’s a little fact that doesn’t seem overly interesting at first: A tipping domino can knock over another domino that is about 1.5 times bigger than it is. But here is the astounding implication: If you start with a tiny domino — only 5 millimeters tall — and then set up a series of dominoes, each 1.5 times larger than the previous one, in fewer than 30 blocks, you will have a domino as large as The Empire State Building, which will crash to the ground as a result of tipping the tiny block over.

Putting your hand in the Large Hadron Collider
For more than 40 years, scientists have tried to figure out what's causing large parts of Canada, particularly the Hudson Bay region, to be "missing" gravity. In other words, gravity in the Hudson Bay area and surrounding regions is lower than it is in other parts of the world, a phenomenon first identified in the 1960s when the Earth's global gravity fields were being charted. Two theories have been proposed to account for this anomaly. But before we go over them, it's important to first consider what creates gravity. Canada Missing Gravity
Double-Slit Experiment The video below shows scientific proof that there is something NOT quite logical or scientific about this universe. The mere act of observation can completely change the outcome of an event! Before I get too ahead of myself, you need to watch the video below to understand:
SExpand In this week's "Ask a Physicist," we're going to figure out why the universe we inhabit isn't Flatland, Tesseractland, or Doubletimeland. Or, at very least, we're going to figure out why those worlds would suck at harboring complex life. Past, Present and Future

10 Strange Things About The Universe Space The universe can be a very strange place. While groundbreaking ideas such as quantum theory, relativity and even the Earth going around the Sun might be commonly accepted now, science still continues to show that the universe contains things you might find it difficult to believe, and even more difficult to get your head around. Theoretically, the lowest temperature that can be achieved is absolute zero, exactly ?
