What would happen if time started going backwards?

If time ran in reverse, all the laws of physics would work the same. The Second Law states that over time, everything moves from an ordered state to a disordered state. It’s the only physical law that can’t go backwards.

Can Time Machine be invented?

Time travel may soon be possible, according to an astrophysicist who believes he’s worked out a way to build a time machine. Professor Ron Mallett from the University of Connecticut in the US claims to have written a scientific equation that could be used to create a device that takes people back in time.

Can we ever reach the speed of light?

So will it ever be possible for us to travel at light speed? Based on our current understanding of physics and the limits of the natural world, the answer, sadly, is no. So, light-speed travel and faster-than-light travel are physical impossibilities, especially for anything with mass, such as spacecraft and humans.

Can parallel universes collide?

Actually the result of different, parallel worlds smashing into each other. The notion that our universe may be just one in a series of endless parallel universes—some very similar, some wildly different—has captivated the hearts and minds of many science fiction fans.

Is the universe in a never-ending cycle?

If so, perhaps it’s been bouncing back and forth in a never-ending cycle of big bangs in which all matter bubbles out of a singularity, followed by big crunches, in which everything gets swallowed up again to form that dense point from which the universe is born again. And the cycle continues over and over and over.

Is the universe slowing down?

There’s also the fact that not only is the universe as we know it expanding, but it’s accelerating in its expansion, with no sign whatsoever of it slowing down (let alone collapsing) anytime soon. Figuring out what could make it hit the brakes and reverse course, then, is tricky.

Could the universe have had a bounce instead of a bang?

With a bounce rather than a bang, Steinhardt says, distant parts of the cosmos would have plenty of time to interact with each other, and to form a single smooth universe in which the sources of CMB radiation would have had a chance to even out. In fact, it’s possible that time has existed forever.

What will the universe look like in the future?

The Universe will become a cold, uniform soup of isolated photons. The Universe we can currently see is made up of clumps of particles, dust, stars, black holes, galaxies, radiation (Credit: NASA/JPL-Caltech/ESA/CXC/STScI) It’s not a particularly dramatic ending, although it does have a satisfying finality.
