Proof That Dark Matter Exists

The way massive objects of the universe bend and distort gravity and light indicates to scientists about the existence of dark matter. The way large objects move about in the universe (velocity) also is a factor pushing towards the probability of much more mass than is visible.

Dark matter provides the gravity and weight in galaxies, which would fall apart if all they had was what is visible to scientists via their various instruments.

Dark Matter Of The Universe

Dark Matter Of The Universe

Dark Matter is a bizarre, unknown ingredient of the universe, which scientists cannot observe directly, but takes up 80 percent of the mass of the universe.

It is not seen by the naked eye as it does not emit light or energy. There are entire galaxies (like Dragonfly 44) that are made up entirely of dark matter. Scientists use particle detectors to detect cosmic rays, energy patterns, gravity, and positrons (anti-electrons) to research dark matter.

Dark Matter Vs Dark Energy

Apart from dark matter, the universe is full of energy, most of which is dark energy.

New data shows that the universe is not running out of energy like previous theories claimed, but is actually expanding at an accelerated rate.

Baryonic And Non-Baryonic Matter

  • Familiar material of the universe contains protons, neutrons and electrons, also known as Baryonic Matter.
  • Dark matter is made up of the same plus also non-baryonic matter (neutrinos, free electrons, supersymmetric particles, axions, and black holes) which is hard to detect.
  • The objects of the universe that may contribute to dark matter are dim brown dwarf stars, white dwarf stars and neutron stars.
  • Supermassive black holes, the size of which is 21 billion times the mass of our Sun, can make up a lot of dark matter by themselves.

The Instruments Of Observing Dark Matter

Particle detectors and other dark matter detecting projects prove the universal interest in dark matter:

  1. From Italy, a particle detector named XENON1T is hunting for dark matter with an ultra-low background.
  2. From South Dakota, the Large Underground Xenon Dark-Matter Experiment (LUX) is hunting for weakly interacting massive particles (WIMP).
  3. IceCube Neutrino Observatory is situated under Antarctica’s ice, hunting for sterile neutrinos.

This app is LOADED with RELEVANT, HELPFUL, AND EDUCATIONAL material. It is creatively intellectual, yet minimal enough to not overstimulate and create a learning block. I am exceptionally impressed with this app!

Don’t look further if you love learning new things. A refreshing concept that provides quick ideas for busy thought leaders.

Shankul Varada

Best app ever! You heard it right. This app has helped me get back on my quest to get things done while equipping myself with knowledge everyday.

Sean Green

Great interesting short snippets of informative articles. Highly recommended to anyone who loves information and lacks patience.

Jamyson Haug

Great for quick bits of information and interesting ideas around whatever topics you are interested in. Visually, it looks great as well.

Laetitia Berton

I have only been using it for a few days now, but I have found answers to questions I had never consciously formulated, or to problems I face everyday at work or at home. I wish I had found this earlier, highly recommended!

Giovanna Scalzone

Brilliant. It feels fresh and encouraging. So many interesting pieces of information that are just enough to absorb and apply. So happy I found this.

Ghazala Begum

Even five minutes a day will improve your thinking. I've come across new ideas and learnt to improve existing ways to become more motivated, confident and happier.
