What was the cause of the explosion of the Big Bang?
The universe began, scientists believe, with every speck of its energy jammed into a very tiny point. This extremely dense point exploded with unimaginable force, creating matter and propelling it outward to make the billions of galaxies of our vast universe. Astrophysicists dubbed this titanic explosion the Big Bang.
Is it possible to say where the Big Bang took place?
Could a four-dimensional being find the center of the expansion, the place where the Big Bang happened? Probably. All places formed in the Big Bang – I mean – Big Stretch, and they’ve been moving away from each other for 13.8 billion years. There’s no one place you can point to and say: the Big Bang happened there.
What caused the Big Bang to happen?
Before the Big Bang there was no space or time. So, it is actually meaningless to ask what caused the Big Bang to happen – there was no Universe in which that cause could have existed. This might seem like a bit of a cheat, but there are other good reasons to suppose a cause for the Big Bang might not exist.
What evidence do we have to prove the Big Bang?
The CMB is not only one of the major pieces of evidence for the Big Bang (it’s a baby picture of the universe…what else could you ask for?), but it’s also a window to even earlier times. We may not be able to perceive the universe before the formation of the CMB, but the physics there leaves an imprint in that radiation field.
Is the Big Bang theory still valid?
You don’t have to take my word for it. Since the idea was first cooked up, the Big Bang theory has survived decades of scientists fighting, scratching, backstabbing, criticizing, undermining, bickering, arguing and even name-calling, all in an attempt to crush their rivals and prove that their pet alternatives were superior. Why?
Did the universe begin with a whimper or a bang?
But we know better today. The Universe began not with a whimper, but with a bang! At least, that’s what you’re commonly told: the Universe and everything in it came into existence at the moment of the Big Bang.
