Time travel?
No.. The only way to time travel is to reverse entropy to the point you want to go which of course takes as much energy to reverse as the energy-potential that exists within now and an earlier version of universe. So I guess the only ones that should even consider time travel are religious people that think there's an omnipotent god that exists outside space-time.
But for the fun of it all, let's say we can actually fold space-time or go faster than light according to the classic sci-fi as well as various scientific hypotheses. The classic grandfather paradox has always been used to describe natures way of making time-travel impossible. Some overcomes this by claiming that by travelling in time you are actually travelling to a parallel universe and thus it's not YOUR space-time grandfather that is killed. That is to me a lame cop-out. I'd go with the fact that you switched your space-time existence and thus are no longer part of any future space-time and can safely kill your grand father (and spend the rest of your time in an 1935 jail house). You leave one frame-of-reference to another frame-of-reference, thus severing a link between you and the old frame-of-reference.
Big bang or cosmic egg or even constant rebirth in mega-verse?
My vision is that mega-verse (a googol times larger than our visible universe? impossible to say) is the real thing and our "universe" is just a tiny little speck, an atom in a grain of sand in all sand on Earth. What is a singularity? According to scientists: "trouble", "we don't know", "I have a head ache" and so on.
Which known events/objects are connected to the word singularity?
Big bang and Black Holes. Connect the dots. If a black hole reaches a mass of say, the amount of mass and energy of our local mini-verse that came into existence 13.7 billion years ago, could that be when it turns into a singularity which in actuality is not an infinitely small point with enormous amount of energy but instead reaches the maturity and cracks like an egg to a new universe?
And imagine if it goes on all the time all over mega-verse? It may take trillions of years for a cosmic egg to mature by being fed nutrients by ageing expanding universes all around where space (and energy/mass) that come in contact with this cosmic egg stop existing in our mega-verse and becomes part of the cosmic egg until it hatches into a new universe.
An infinite rebirth of local universes all around us that can keep on going due to old universes constant expansion and even though a 500 billion year old universe may seem to be so cold there are many old and new universes that expands all around the cosmic eggs and feeds them through trillions of years until they hatch..
So the word singularity is, according to my idea, the exact moment a cosmic egg reaches the point where the underlying fabric of space reaches it's maximum strain and the cosmic egg breaks the space-time fabric via a minuscule little "wormhole" or needle-hole where the cosmic egg implodes (in it's position) into a new universe where the implosion at that point breached the limit of the fabric of space time and thus gravity stopped existing for an infinitesimal amount of time, enough time for the implosion-turned-explosion_inflation. Time is not really the right description since time in itself doesn't exist at that point, it doesn't exist until the new universe has begun expanding the space-time "surface" where all energy and radiation expands into, cools down enough for gravity to have an effect on the very earliest sub particles smashing into each other leading to more clumping together and hydrogen atoms exist and clump together etc. etc..
Let's see.. was there more?
Oh yes, Time.
It was about my view of time being the result of the potential between two states, not a constant forward moving "force" that pushes us along some 2-dimensional time axis (which is how our brains interpret "time"). What made us interpret time like that was the development of short- and long-term memory. Without any of those time would simply not exist to us. And neither would we because we would have no sense of anything. We'd be completely non-functioning (we'd never be born to begin with). We already know time is not static, it's different from person to person, from place to place, relative to something moving faster/slower or affected by gravity etc.
That tells me time is a mesh of potentialities in space-time. In fact, it may not need to be classified as the "4th dimension" but rather an intrinsic part of the 3-dimensional existence we can sense and not a dimension or function of it's own. However, the way we experience time is an illusion but a necessary one. Our brains evolved towards the "arrow of time"/"cause and effect" way to interpret different states simply because it's the best way for our species (for now) to function and keep evolve. No gravitons, no 4th dimension, just an intrinsic part/result of 3-dimensional state-changes.
