they probably don't use it since all the risks and such.


Depending on the complexity it could be reproducible by anyone so one would expect to still see time travelers.

Here is why risk would not factor into this if it were possible. If you are at the end of the universe and energy is running out, but you have enough energy to travel back in time to when there was more energy, and the only outcome is non-existence through death then the potential reward outweighs any risk as the risk is the same either way.

Perhaps humanity will find a way to channel energy from another universe.

I myself would like to visit another universe and see alternate versions of myself and people I know... Anything is possible in the multiverse.

steeljaw354, that may actually be possible without leaving the universe. If the universe is infinite, then eventually the maximum number of ways particles could be arranged would be met and previous arrangements would have to be duplicated. This may result in an Earth identical to ours. Of course, actually reaching this parallel Earth would be rather difficult, but it is an interesting concept.

Well if the universe is infinite, there is always the chance of alternate dimensions in the same place, on another dimensional plane.

Unless there is some hidden way to punch into a new universe without dying or manufacture spacetime conditions that allow for infinite energy, it is unlikely anything will survive. Entropy really is going to be the death of everything.


well what if we believe hard enough in the whitehole / blackhole theory and find a way to protect ourselves from the tidal forces and just ride to the other side smile

More seriously, the problem is that there is no other side to go to. Mathematically we can imagine black holes as bridges to elsewhere, but in reality they don't lead anywhere but to singularity.

It is very interesting and quite true if the universe is infinite, though statistically those identical Earths would lie far beyond our cosmic horizon so we could never reach them. Unless we believe hard enough. smile

EmDrive: Nasa Eagleworks' paper has finally passed peer review, says scientist in the know

Quote

An independent scientist has confirmed that the paper by scientists at the Nasa Eagleworks Laboratories on achieving thrust using highly controversial space propulsion technology EmDrive has passed peer review, and will soon be published by the American Institute of Aeronautics and Astronautics (AIAA).

Dr José Rodal posted on the Nasa Spaceflight forum – in a now-deleted comment – that the new paper will be entitled "Measurement of Impulsive Thrust from a Closed Radio Frequency Cavity in Vacuum" and is authored by "Harold White, Paul March, Lawrence, Vera, Sylvester, Brady and Bailey".

There is also a line of text that EmDrive enthusiasts believe could be from the paper's extract, which reads: "Thrust data in mode shape TM212 at less than 8106 Torr environment, from forward, reverse and null tests suggests that the system is consistently performing with a thrust to power ratio of 1.2 +/- 0.1 mN/Kw ()".

Rodal also revealed that the paper will be published in the AIAA Journal of Propulsion and Power, a prominent journal published by the AIAA, which is one of the world's largest technical societies dedicated to aerospace innovations.

Careful with the source if you are on mobile, it tends to spam your phone with adware and it is a pain to remove.

Basically it may work on a physics "error" of sorts, so simulation confirmed?

WaveNet: A Generative Model for Raw Audio
Quote


This post presents WaveNet, a deep generative model of raw audio waveforms. We show that WaveNets are able to generate speech which mimics any human voice and which sounds more natural than the best existing Text-to-Speech systems, reducing the gap with human performance by over 50%.

We also demonstrate that the same network can be used to synthesize other audio signals such as music, and present some striking samples of automatically generated piano pieces.

Scared of superintelligent AI? You should be, says neuroscientist and philosopher Sam Harris — and not just in some theoretical way. We're going to build superhuman machines, says Harris, but we haven't yet grappled with the problems associated with creating something that may treat us the way we treat ants.

In addition to the increasing carbon dioxide levels, oxygen throughout the atmosphere appears to be falling.

I wonder if this trend will continue into the future.

Factoring in current CO2 emissions, methane emissions, deforestation, ocean acidifcation, and the reduction of oxygen in the atmosphere it would seem humans have less than 1000 years for Earth to remain habitable and that may be optimistic.
