Is the Big Bang just a theory?

As a hypothesis – lacking supporting observational evidence, it was that rather than a theory, although commonly referred to as such – it essentially died with Hoyle. Today, the Lambda-CDM Big Bang model is the only theory that makes any testable predictions and that is supported by observations.

Will the universe end?

Astronomers once thought the universe could collapse in a Big Crunch. Now most agree it will end with a Big Freeze. ... Trillions of years in the future, long after Earth is destroyed, the universe will drift apart until galaxy and star formation ceases. Slowly, stars will fizzle out, turning night skies black.

What are the main points of the Big Bang theory?

At its simplest, it says the universe as we know it started with an infinitely hot, infinitely dense singularity, then inflated — first at unimaginable speed, and then at a more measurable rate — over the next 13.8 billion years to the cosmos that we know today.

What evidence helps to support the Big Bang theory?

Two major scientific discoveries provide strong support for the Big Bang theory: • Hubble's discovery in the 1920s of a relationship between a galaxy's distance from Earth and its speed; and • the discovery in the 1960s of cosmic microwave background radiation.

Astrophysicists dubbed this titanic explosion the Big Bang.

How long will universe last?

22 billion years in the future is the earliest possible end of the Universe in the Big Rip scenario, assuming a model of dark energy with w = −1.5. False vacuum decay may occur in 20 to 30 billion years if Higgs boson field is metastable.

Will we ever travel to other galaxies?

The technology required to travel between galaxies is far beyond humanity's present capabilities, and currently only the subject of speculation, hypothesis, and science fiction. However, theoretically speaking, there is nothing to conclusively indicate that intergalactic travel is impossible.

Does time have an end?

“Time is unlikely to end in our lifetime, but there is a 50% chance that time will end within the next 3.7 billion years,” they say. That's not so long! It means that the end of the time is likely to happen within the lifetime of the Earth and the Sun. ... At least, not for another 3.7 billion years.
