Scientists Say We Can’t Travel Back in Time

Scientists are now saying that it would be a lot easier to travel to the future than the past. Professor Greene, a consultant for Déjà Vu says, “If you want to know what the Earth is like one million years from now, I’ll tell you how to do that. Build a spaceship. Go near the speed of light for a length of time—that I could calculate. Come back to Earth, and when you step out of your ship you will have aged perhaps one year while the Earth would have aged one million years. You would have traveled to Earth’s future.”

I don’t know about the past, but if what that guy says works without dying, then I think it’s possible to travel into the future. A lot of worries in time travel come from the supposed dangers at such high speeds. But we don’t really know how fast we are traveling now. I’m currently sitting, but then the earth is spinning at around 800mph, the earth orbiting about 66,600mph around the sun, and the sun around the galaxy, the galaxy around the…

More Water Than We Thought On Mars

Scientists from a joint NASA Italian Space Agency say that there could be more water on Mars then previously thought. Jeffrey Plaut says that, “We could estimate the amount of water on Mars before, but not with confidence.” He goes on saying that with calculations by the Mars Advanced Radar for Subsurface and Ionospheric Sounding, (MARSIS) there could be enough ice to cover Mars with a layer of water 11 meters/36 feet deep.

I remember reading when they first discovered that there was evidence of water on Mars (a few months ago)… and now they’re saying that there is enough water on Mars to cover it’s self 36 feet deep. Although I do see how this is possible, if there is that much, would it be a little more obvious?

Nerves Transmit Sound, Not Electricity?

A new theory created by Thomas Heimburg of Copenhagen University states that nerves transmit signals through sound rather than electrical impulses. He bases his theory off of the inconsistencies in electrical impulse-nerve theory. Laws dealing with thermodynamics and how electrical impulses should produce heat while traveling through the nerve, but they don’t.

I know there are flaws in the electrical impulse-nerve theory, but have you ever heard of brain waves? We can measure electrical activity in the brain.
