Just because they're a scientist doesn't mean that they're not bat-shit crazy.

One of the things I love most about people who deny that global climate is getting warmer or that there's no way the Twin Towers could have fallen due to jetliners smashing into them is the "trump card" of pulling out a scientist that agrees with them. All you need is one, right? And, suddenly, POOF! You're theory is valid. Except it's not. There's a thing called consensus. Besides, many scientists are nuts and believe all sorts of crazy shit.

Did a UFO deliberately crash into a meteor to save Earth 100 years ago? That's what one Russian scientist is claiming.

Dr. Yuri Labvin, president of the Tunguska Spatial Phenomenon Foundation, insists that an alien spacecraft sacrificed itself to prevent a gigantic meteor from slamming into the planet above Siberia on June 30, 1908.

The result was was the Tunguska event, a massive blast estimated at 15 megatons that downed 80 million trees over nearly 100 square miles. Eyewitnesses reported a bright light and a huge shock wave, but the area was so sparsely populated no one was killed.

Most scientists think the blast was caused by a meteorite exploding several miles above the surface. But Labvin thinks quartz slabs with strange markings found at the site are remnants of an alien control panel, which fell to the ground after the UFO slammed into the giant rock.

"We don't have any technologies that can print such kind of drawings on crystals," Labvin told the Macedonian International News Agency. "We also found ferrum silicate that can not be produced anywhere, except in space."
