What is all matter made up of?
Explain that all matter on Earth exists in the form of a solid, liquid, or gas, and that solids, liquids, and gases are all made of extremely tiny particles called atoms and molecules. Tell students that an atom is the smallest building block of matter and a molecule is two or more atoms connected together.
Is dark matter exotic matter?
One leading hypothesis is that dark matter consists of exotic particles that don’t interact with normal matter or light but that still exert a gravitational pull. Several scientific groups, including one at CERN’s Large Hadron Collider, are currently working to generate dark matter particles for study in the lab.
Is dark energy exotic?
There may be an exotic form of dark energy lurking in the universe, and it could explain a stubborn discrepancy in measurements of the universe’s expansion rate. This so-called early dark energy might have existed in the universe’s infancy, then flickered out of existence soon after.
What’s the opposite of dark matter?
Antimatter is just regular matter with a few properties flipped, such as the electric charge. For example, the antimatter version of an electron is a positron. They both have the same mass, but have opposite electric charge. Antimatter is not as exotic as science fiction makes it out to be.
Does dark matter exist?
Because dark matter has not yet been observed directly, if it exists, it must barely interact with ordinary baryonic matter and radiation, except through gravity. Most dark matter is thought to be non-baryonic in nature; it may be composed of some as-yet undiscovered subatomic particles.
Can we live without matter?
So yes, you absolutely can have energy without matter, in empty space. Yes. There is no reason that these non-matter particles cannot exist without matter particles existing.
Is Planet nine a black hole?
They propose that instead of being free floating planets, these objects are primordial black holes. Konstantin Batygin commented on this, saying while it is possible for Planet Nine to be a primordial black hole, there is currently not enough evidence to make this idea more plausible than any other alternative.
Can a black hole reach Earth?
A newfound black hole may be the closest black hole to Earth, and you can spot its cosmic home in the night sky without a telescope. But you won’t be able to see the black hole itself; the massive object has such a strong gravitational pull that nothing — not even light — can escape it.
