Considering the Practicalities of Time Travel

Introduction:

Click on the image to expand

The act of traveling either back or prematurely forward in time has often been a popular concept in science fiction narratives, whether in the plots of motion pictures or books. The very idea of exploring "what could have been" or "what could be" is something that has always fascinated humanity, regardless of the cultural backdrop. It is therefore no wonder time travel has become perhaps the most well-known hypothetical scenario of either revisiting time or "skipping" time on Earth to another time frame.

The concept has literally given story writers and movie producers plenty of material to work with; such science fiction motion pictures like Star Trek, Super Man, Back to the Future, The Twelve Monkeys, and the like come to mind. Why not? There is almost no limit to what can be imagined, as a theme around time travel, whether it has to do with visiting new worlds in our universe, someone accidentally waking up in very different time from his/her own, or someone yearning to change a situation to his/her advantage in their present time, with the aid of changing the course of history by altering some event or another, and the list can just go on.

In all seriousness though, just how practical is the concept of managing the course of history with the manipulation of time?

Conserving Net Neutrality and Internet Freedom

With ever-increasing war on Net neutrality and Internet freedom, all persons who value a free Internet will have to pitch in and put up a relentless fight, rather than outsourcing the responsibility merely to a caring few!

The Internet is the one place that has resisted falling victim to complete subordination to and the tight clutches of arbitrary human-made political boundaries and establishment censorship. Ruling and corporate oligarchies world over are increasingly compelled to recognize the social power of the Internet, and what this means for the prospect of their continued consolidation of power; take for instance, the role that a free Internet has already played, and can continue to play in the foreseeable future, in mobilizing people to take action in a critical mass—whether it be in the service of taking fights to the streets for economic and social justice, the exercise of petitioning so-called local/state representatives, harnessing the collective power of individuals' wallets at the national or transnational stage, or in the service of building platforms which open up channels for proven grassroots leaders to make significant inroads into legislative and/or executive administrative posts.

What used to be an exclusive monopoly of the rich few, i.e. having their voices amplified in and by mass media, is no more, thanks in no small measure to the explosion of the Internet; now the average person too can have a voice almost as loud and powerful! It's then easy to see why the ruling establishment and their corporate allies are working hard to end Internet neutrality and freedom; dictatorships around the world, or perhaps better known as the "establishment" or the "ruling class" to many—whether it be plutocracies masquerading as "democracies" or self-described "socialists", are now scrambling to muzzle the average folk on the web! Whether this ambition will come to pass or not will depend on the activeness of every average individual who values and utilizes the Internet as a vehicle for social relations that is free from authoritarian censorship, whether such censorship comes from alleged capitalist, socialist or totalitarian regimes!

PS: Speaking of Internet freedom and its safeguard, there are resourceful Internet concerns out there, whose mission is to do just that, and it would be tragic to let them quietly go into oblivion. A good example of this is the fittingly-called "Internet Archive Wayback Machine"—and no, said Internet concern has no links [financial or otherwise] to this site or its authorship; however, insofar as it has proven to be a resourceful asset (e.g. in preserving web pages that have become lost, withdrawn or stripped off their original features), it is worth supporting.

Stephen Hawking

1942-2018

Well, time appears to have stopped ticking for Mr. Hawking, but what of "time" itself?

one can get rid of the problem of time having a beginning, in a similar way in which we got rid of the edge of the world. Suppose the beginning of the universe was like the South Pole of the earth, with degrees of latitude playing the role of time. The universe would start as a point at the South Pole. As one moves north, the circles of constant latitude, representing the size of the universe, would expand. To ask what happened before the beginning of the universe would become a meaningless question, because there is nothing south of the South Pole.
...

in the imaginary time direction, space-time is finite in extent, but doesn't have any boundary or edge. The predictions of the no boundary proposal seem to agree with observation. The no boundary hypothesis also predicts that the universe will eventually collapse again. However, the contracting phase, will not have the opposite arrow of time, to the expanding phase. So we will keep on getting older, and we won't return to our youth. Because time is not going to go backwards, I think I better stop now.

It (time) could very well go on ticking indefinitely in the bigger scheme of things beyond our own "big-bang" triggered clock, rendering our puny individual life spans almost next to nothingness, if not quite nothing, only because we will have technically existed before our exit.

It is safe to say that Mr. Hawking has been viewed by many as having been "intellectually gifted", but "intelligence" which humans generally take for granted, even as members of the species lay it to waste, is not a sure guaranteer of an evolutionary fitness with an extraordinary lifespan advantage:

It is likely that evolution is a random process, with intelligence as only one of a large number of possible outcomes. It is not clear that intelligence has any long-term survival value. Bacteria, and other single cell organisms, will live on, if all other life on Earth is wiped out by our actions

Who really knows; perhaps, it comes down to the matter of how "intelligence" is managed that will ultimately determine the longevity of its evolutionary value. If the current state of affairs in the world of humanity is any indicator to go by, as subliminally suggested in the final line of the quote above, then this longevity does not look promising.
