A lab in Tennesee that does research in neutron, nuclear and clean energy had to debunk the myth that they were somehow attempting to open portals to other dimensions. Though if I ever learned anything from popular science fiction, if a research lab says they aren’t opening portals to parallel universes, my instinct tells me that they are totally opening portals to other dimensions. So you can imagine why folks would be skeptical.

Research scientist Leah Broussard explains in the video above that the experiments they are doing at the Oak Ridge National Laboratory (which is managed by the US Department of Energy) aren’t exactly about building portals to other dimensions. Instead, they involved “looking for new ways that matter we know and understand, that makes up our universe, might interact with the dark matter that makes up the majority of our universe, which we don’t understand.”

Broussard also explains when a particle physicist says portal, they mean it in a figurative sense. All this talk of parallel universes came when her research was released and people started making connections to the Netflix show, Stranger Things. A show that, coincidentally, features kids stumbling across a shady government agency opening portals to other dimensions full of monsters, in the ’80s.

What is time? Why is it so different from space? And where did it come from? Scientists are still stumped by these questions — but working harder than ever to answer them.

St. Augustine said of time, “If no one asks me, I know what it is. If I wish to explain to him who asks, I don’t know.” Time is an elusive concept: We all experience it, and yet, the challenge of defining it has tested philosophers and scientists for millennia.

It wasn’t until Albert Einstein that we developed a more sophisticated mathematical understanding of time and space that allowed physicists to probe deeper into the connections between them. In their endeavors, physicists also discovered that seeking the origin of time forces us to confront the origins of the universe itself.

To solve a long-standing puzzle about how long a neutron can “live” outside an atomic nucleus, physicists entertained a wild but testable theory positing the existence of a right-handed version of our left-handed universe. They designed a mind-bending experiment at the Department of Energy’s Oak Ridge National Laboratory to try to detect a particle that has been speculated but not spotted. If found, the theorized “mirror neutron”—a dark-matter twin to the neutron—could explain a discrepancy between answers from two types of neutron lifetime experiments and provide the first observation of dark matter.

“Dark matter remains one of the most important and puzzling questions in science—clear evidence we don’t understand all matter in nature,” said ORNL’s Leah Broussard, who led the study published in Physical Review Letters.

Special relativity famously dictates that no known object can travel faster than the speed of light in a vacuum – making it unlikely that humans will ever send spacecraft to explore beyond our local area of the Milky Way. However, new research by Erik Lentz at the University of Göttingen suggests there could be a way beyond this limit. The only catch is that his scheme requires vast amounts of energy and so may never actually be able to propel a spacecraft (Class. Quant. Grav. 38 075015).

Lentz proposes that conventional energy sources could arrange the structure of space–time in the form of a soliton – a robust singular wave. This soliton would act like a “warp bubble’”, contracting space in front of it and expanding space behind. Unlike objects within it, space–time itself can bend, expand or warp at any speed. A spacecraft contained in a hyperfast bubble could therefore arrive at its destination faster than light would in normal space without breaking any physical laws.

It had been thought that the only way to produce a warp drive was by generating vast amounts of negative energy – perhaps by using some sort of undiscovered exotic matter or by manipulating dark energy. To get around this problem, Lentz constructed an unexplored geometric structure of space–time to derive a new family of solutions to Einstein’s general relativity equations called positive-energy solitons. Though Lentz’s solitons appear to conform to Einstein’s general theory of relativity and remove the need to create negative energy, space agencies will not be building warp drives any time soon, if ever. Part of the reason is that Lentz’s positive-energy warp drive requires a huge amount of energy. According to Lentz, a 100 m radius spacecraft would require the energy equivalent to “hundreds of times the mass of Jupiter”.

As they probe the secrets of the cosmos, scientists question whether our reality is but one in a multiverse.

After some serious number crunching, a UBC researcher has come up with a mathematical model for a viable time machine.

Ben Tippett, a mathematics and physics instructor at UBC’s Okanagan campus, recently published a study about the feasibility of time travel. Tippett, whose field of expertise is Einstein’s theory of general relativity, studies black holes and science fiction when he’s not teaching. Using math and physics, he has created a formula that describes a method for time travel.

“People think of time travel as something as fiction,” says Tippett. “And we tend to think it’s not possible because we don’t actually do it. But, mathematically, it is possible.”

Time travel into the past is a tricky thing. We know of no single law of physics that absolutely forbids it, and yet we can’t find a way to do it, and if we could do it, the possibility opens up all sorts of uncomfortable paradoxes (like what would happen if you killed your own grandfather).

But there could be a way to do it. We just need to find a wormhole first.

According to Big Bang Theory, About 13.7 billion years ago, our entire universe existed as a singularity. It is really Difficult to imagine, how all the matter in the universe and space itself, existed in a form smaller than a subatomic particle.
But here, even more difficult question suddenly arises: What existed before the big bang?
Actually it doesn’t make any sense to ask, what happened before the big bang, as it is believed that time itself did not exist before the big bang!!! Space and time both were created after the big bang.
It is something like asking, what part of earth is north of the north pole. The north Pole is the most northern point on earth and so there is nowhere north of it.
But there is also possibility that something was there before the Big Bang happened
According to the “the big Bounce” theory, our universe is the recycled result of another universe, that dies and.
collapses in on itself. This collapsing universe would come back to a singularity before bouncing back out. It results in the big bang and a brand-new universe is again created.
But there is a problem with the big Bounce theory. Actually according to current observations, our universe is constantly expanding faster than ever before. But the big Bounce theory requires the universe to be contracted so that it can reach at the stage of singularity.
Another Possibility is of the parallel universe. According to this theory our universe is not the only Universe that exists. it is one of many universes in the Grand multiverse.
According to some scientists it may also be possible, our universe is at the other end of a black hole called a white hole.
A White hole has properties just opposite to that of the black hole.
In general relativity, a white hole is a hypothetical region of spacetime which cannot be entered from the outside, although matter and light can escape from it. In this sense it is the reverse of a black hole, which can only be entered from the outside from which matter and light cannot escape. Unlike black holes, white holes spew material into space rather than sucking material in.
All that we have discussed here, are the possibilities, what existed before the big bang. Actually we don’t really know, what really caused the big bang and what was present before it. Was there no space and time before Big Bang is also a mystery.
