Re: Time and Space Travel

The answer is:


Time and Space Travel exists.

Time Travel exists because we travel through time every moment of our lives, and we travel through space every time we move around.

Therefore, if on a small scale it is possible, we can assume that it is possible on a large scale. However, by the time we get to a stage where time travel is possible we will only go forward, never backward, purely because we are still discovering things, if backwards time travel was possible we would already know about it.

Mining the Moon

How can we use the resources that are already on the Moon to make human exploration of the satellite as economical as possible?

If you were transported to the Moon this very instant, you would surely and rapidly die. That's because there's no atmosphere, the surface temperature varies from a roasting 130 degrees Celsius (266 F) to a bone-chilling minus 170 C (minus 274 F). If the lack of air or horrific heat or cold don't kill you then micrometeorite bombardment or solar radiation will. By all accounts, the Moon is not a hospitable place to be.

Here's when machines will take your job, as predicted by A.I. gurus

Surprising Science

While technology develops at exponential speed, transforming how we go about our everyday tasks and extending our lives, it also offers much to worry about. In particular, many top minds think that automation will cost humans their employment, with up to 47% of all jobs gone in the next 25 years. And chances are, this number could be even higher and the massive job loss will come earlier.

Scientists reactivate cells from 28,000-year-old woolly mammoth

"I was so moved when I saw the cells stir," said 90-year-old study co-author Akira Iritani. "I'd been hoping for this for 20 years."

Yamagata et al.
Surprising Science
  • The team managed to stimulate nucleus-like structures to perform some biological processes, but not cell division.
  • Unless better technology and DNA samples emerge in the future, it's unlikely that scientists will be able to clone a woolly mammoth.
  • Still, studying the DNA of woolly mammoths provides valuable insights into the genetic adaptations that allowed them to survive in unique environments.
