Is a closed universe possible?

We show that since the Planck power spectra prefer a closed universe, discordances higher than generally estimated arise for most of the local cosmological observables, including BAO.
Planck evidence for a closed Universe and a possible crisis for cosmology.

Does the past still exist?

In short, space-time would contain the entire history of reality, with each past, present or future event occupying a clearly determined place in it, from the very beginning and for ever. The past would therefore still exist, just as the future already exists, but somewhere other than where we are now present.

Is it possible to recreate the universe?

Recreating The Universe In The Lab : 13.7: Cosmos And Culture Can scientists create universes in the lab? Although that may not be possible, physicists can recreate the young universe in high energy particle collisions. Recent results indicate that the young universe may be stranger than anticipated.

What was there before the universe?

In the beginning, there was an infinitely dense, tiny ball of matter. Then, it all went bang, giving rise to the atoms, molecules, stars and galaxies we see today. Or at least, that’s what we’ve been told by physicists for the past several decades.

Is time Travelling possible?

Yes, time travel is indeed a real thing. But it’s not quite what you’ve probably seen in the movies. Under certain conditions, it is possible to experience time passing at a different rate than 1 second per second. And there are important reasons why we need to understand this real-world form of time travel.

How many universes are there?

In a new study, Stanford physicists Andrei Linde and Vitaly Vanchurin have calculated the number of all possible universes, coming up with an answer of 10^10^16.

Who created the world?

A creator deity or creator god (often called the Creator) is a deity or god responsible for the creation of the Earth, world, and universe in human religion and mythology.

What’s inside a black hole?

What is at the center of a black hole? At the center of a black hole, it is often postulated there is something called a gravitational singularity, or singularity. This is where gravity and density are infinite and space-time extends into infinity.
