Can our universe collide with another?

In the multiverse hypothesis, our universe could have popped into existence near another universe. When it expanded, it ran into the neighboring universe; the resulting collision would have left a mark (like a bruise) on our universe.

Is there a universe inside a universe?

If the size of the universe blows your mind, just wait. In today’s edition of Physics Letters B, theoretical physicist Nikodem Poplawski of Indiana University suggests that our universe could be located within the interior of a wormhole which itself is part of a black hole that lies within a much larger universe.

What is the cold spot in the universe?

First observed by NASA’s Wilkinson Microwave Anisotropy Probe (WMAP) in 2004, and later confirmed by the European Space Agency’s Planck satellite, the so-called “CMB cold spot” is about 70 μK colder than the average CMB temperature, and appears in the southern celestial hemisphere.

Is universe inside black hole?

The birth of our universe may have come from a black hole. Most experts agree that the universe started as an infinitely hot and dense point called a singularity. It is, in fact, and some physicists say they could be one and the same: The singularity in every black hole might give birth to a baby universe.

What is Edge of the universe?

The edge simply marks the dividing line between locations that earthlings can currently see and locations that we currently cannot. And although our observable universe has an edge, the universe as a whole is infinite and has no edge.

Are we in KBC void?

As with other voids, it is not completely empty but contains the Milky Way, the Local Group, and a larger part of the Laniakea Supercluster. The Milky Way is within a few hundred million light-years of the void’s center.

Could our universe be inside a wormhole?

Theoretical physicist Nikodem Poplawski from Indiana University has taken things a step further by proposing that perhaps our universe could be located within the interior of a wormhole which itself is part of a black hole that lies within a much larger universe. Whoa. I may have just lost my bearings.

Are there other universes besides our own?

From science fiction to science fact, there is a concept that suggests that there could be other universes besides our own, where all the choices you made in this life played out in alternate realities. The concept is known as a “parallel universe,” and is a facet of the astronomical theory of the multiverse.

Could there be an atom inside another universe?

Another reason why the universe could never be an atom inside another universe is quantum mechanics. According to quantum mechanics, the electrons in an atom are not on one specific position, but they are everywhere around the nucleus at the same time]

Is there such a thing as a parallel universe?

Science fiction loves the idea of a parallel universe, and the thought that we might be living just one of an infinite number of possible lives. Multiverses aren’t reserved for “Star Trek,” “Spiderman” and “Doctor Who,” though.
