What is the Big Bang?

The Big Bang was an INCREDIBLY large explosion that created our universe today.

Initially after this explosion, the universe began expanding at an unthinkable speeds, however as time progressed, it slowed down to a more "reasonable pace"

Scientists were able to discover the presence of the Big Bang through something known as Cosmic Background Radiation. CBR is a faint light that is almost as old as the universe itself. It serves as a lens through which the beginning of the universe can be seen.

Who would've thought that something as well thought out as our universe would've began with a BANG.

The Braneworld Theory

The braneworld theory states that in order for the universe to have survived, it would have had to create relatively small "black holes". Moreover, this theory can be experimented upon.

This theory suggests that we are in a three dimensional membrane that exist inside the bulk or the higher dimensional space.

In the case of the Randall-Sundrum model, such tests could involve measuring the gravitational waves that are emitted by the black holes thus linking one brane to another.



Dark Matter Of The Universe

Dark Matter is a bizarre, unknown ingredient of the universe, which scientists cannot observe directly, but takes up 80 percent of the mass of the universe.

It is not seen by the naked eye as it does not emit light or energy. There are entire galaxies (like Dragonfly 44) that are made up entirely of dark matter. Scientists use particle detectors to detect cosmic rays, energy patterns, gravity, and positrons (anti-electrons) to research dark matter.



While a perfectly flat universe would extend out to infinity , a flat universe with a multiply-connected topology would have finite size. If we could somehow determine whether one or more dimensions are wrapped in on themselves, then we would know that the universe is finite in that dimension. We could then use those observations to measure the total volume of the universe.

But how would a multiply-connected universe reveal itself?
