I have thought for a long time that the past ,present , future are happening all at the same time
The major world religions state that is what is happening. Everything is actually present to God and in the next dimension everything in this dimension is happening all at once to them there (and we are there too but don't realize it here). At this time, it seems we are stick 'in time' but in actuality we are outside of time and just experiencing something inside of time while we are outside it. We are 'really' elsewhere ... or should I say, we are really somewhere else in time?
The author of that article, Lee Billings, is not one of the authors of the paper written by Julian Barbour, Tim Koslowski, and Flavio Mercati. If you can read the paper itself, it's usually better because that goes right to the source instead of someone else's interpretation which may or may not be flawed in some way (I can find examples where science writers have made gross interpretation errors of scientific papers). Billings talks about inflation, and then appears to suggest the new research is somehow a solution to the problems with inflation, however if the authors of the paper believe that to be the case, they failed to mention it because I searched the paper for "inflation" and it's not mentioned in the paper itself, only in one of the references.

If anyone here can understand this article upon the first read, I want to be your friend :$ I can't.
It is widely believed that special initial conditions must be imposed on any time-symmetric law if its solutions are to exhibit behavior of any kind that defines an ‘arrow of time’. We show that this is not so.
So in summary their paper says time's arrow is the result of a universal law, and not a result of initial conditions. It doesn't say some of the things the article says or implies.
We conclude that the origin of time’s arrow is not necessarily to be sought in initial conditions but rather in the structure of the law which governs the Universe.

We live in a universe where entropy increases; therefore we experience time moving "forward" with that increase in entropy. But if there was a universe where entropy decreased over time, then time moving "forward" in that universe would actually seem backward to us.
...but it would not be time defining what entropy does, but rather entropy defining how time is perceived. Maybe time is a by-product of entropy, not the other way around.
Fascinating stuff great thread

A two branched time's arrow and increasing entropy, gravity, and cosmic inflation is part of the discussion of this theory and article discussion. The prospect of this being 'testable' and a provable theory is amazing to me. The barriers between the two branches ... that's what I'd like to know about. Anyways, for those interested in this type of discussion, you may find this article interesting.
Business Insider - New Theory : We Live In The Past Of A Parallel Universe
Part of the article quoted here.
Although the model is crude, and does not incorporate either quantum mechanics or general relativity, its potential implications are vast. If it holds true for our actual universe, then the big bang could no longer be considered a cosmic beginning but rather only a phase in an effectively timeless and eternal universe. More prosaically, a two-branched arrow of time would lead to curious incongruities for observers on opposite sides. “This two-futures situation would exhibit a single, chaotic past in both directions, meaning that there would be essentially two universes, one on either side of this central state,” Barbour says. “If they were complicated enough, both sides could sustain observers who would perceive time going in opposite directions. Any intelligent beings there would define their arrow of time as moving away from this central state. They would think we now live in their deepest past.”
What’s more, Barbour says, if gravitation does prove to be fundamental to the arrow of time, this could sooner or later generate testable predictions and potentially lead to a less “ad hoc” explanation than inflation for the history and structure of our observable universe.
This is not the first rigorous two-futures solution for time’s arrow. Most notably, California Institute of Technology cosmologist Sean Carroll and a graduate student, Jennifer Chen, produced their own branching model in 2004, one that sought to explain the low-entropy origin of time’s arrow in the context of cosmic inflation and the creation of baby universes. They attribute the arrow of time’s emergence in their model not so much to entropy being very low in the past but rather to entropy being so much higher in both futures, increased by the inflation-driven creation of baby universes.
There was one theorist who gave the analogy that likened time to a fully-developed, yet static, landscape -- and what we perceive as the passage of time is simply us moving through and experiencing that landscape.

You are quite close to my thinking !! B-)
And, may I add:
Did not all of us noticed that EVERYTHING is spinning/rotating ??
. . .from the smallest to the largest ?
Sooooo, is that "spinning" generating the "time" ?
. . .or . . .?

is it possible to figure out whether we are moving forwards or backwards?
That'd be interesting
The great secret known to Apollonius of Tyana, Paul of Tarsus, Simon Magus, Asklepios, Paracelsus, Boehme and Bruno is that: we are moving backward in time. The universe in fact is contracting into a unitary entity which is completing itself. Decay and disorder are seen by us in reverse, as increasing. These healers learned to move forward in time, which is retrograde to us.
Apollonius of Tyana, writing as Hermes Trismegistos, said "That which is above is that which is below." By this he meant to tell us that our universe is a hologram, but he lacked the term.
The phenomenal world does not exist; it is a hypostasis of the information processed by the Mind.
