BREAKING🚨: Earth may be trapped inside a giant void in space, scientists say
Earth and the rest of the Milky Way could be floating in a billion-light-year-wide cosmic void, according to new research.
By looking at the echoes left by the ‘soundwaves' of the Big Bang, a team of astronomers discovered that our corner of the Universe could be far emptier than we first thought.
If true, the theory could answer one of the biggest problems in cosmology, known as the Hubble Tension – the fact that how fast our Universe is expanding changes depending on how you measure it.
Astronomers have long battled with this issue. When they measure the expansion rate by looking at the distant Universe, it’s markedly slower than the value they get from examining our local corner of the cosmos.
Ever wondered how many Earthlike Planets exist in the observable Universe? Let’s do the Math. [thread]⤵️
We’re gonna calculate how many Earth sized planets orbit within the habitable zone of Sunlike stars across the visible universe.
There are about 2 planets around an average star, about 100 billion stars in a typical galaxy, and about 2 trillion galaxies in the observable universe.
Multiplying these numbers gives us 4 x 1023 (400,000,000,000,000,000,000,000) planets in the observable universe.
But what fraction are in the habitable zone, and what fraction are Earth sized?
