Ilmuwan Ungkap Kemungkinan Dark Energy dan Dark Matter Saling Berinteraksi
Artikel membahas teori baru bahwa dark energy dan dark matter, yang membentuk sekitar 95 persen isi alam semesta, kemungkinan saling berinteraksi. Pengamatan Dark Energy Spectroscopic Instrument (DESI) pada 2024-2025 menunjukkan dark energy tidak sepenuhnya konstan dan kekuatannya mencapai puncak sekitar dua miliar tahun lalu sebelum melemah, didukung penelitian fisikawan Justin Khoury yang sejak 2005 mempelajari kemungkinan interaksi keduanya. Teori ini juga dikaitkan dengan Hubble tension serta konsep dark dimension dalam teori string, meski masih memerlukan pengujian astrofisika lebih lanjut.
Poin-Poin Utama
- Dark energy and dark matter estimated to make up about 95% of the universe.
- Dark energy accounts for roughly 70% and dark matter roughly 25% of the cosmos.
- Both components cannot be directly observed because they do not emit, reflect, or absorb light.
- DESI observations in 2024 and 2025 suggest dark energy may not be fully constant.
- Dark energy strength may have peaked around two billion years ago before weakening.
- Physicist Justin Khoury from the University of Pennsylvania has studied their interaction since 2005.
- Khoury's latest theory, developed with Meng-Xiang Lin and Mark Trodden, models simultaneous energy changes.
- One possibility is that some dark matter energy transfers to dark energy.
- Hubble tension shows a roughly 9% difference in expansion rate measurements.
- The dark dimension concept in string theory links dark matter and dark energy through extra dimensions.
- Changes in dark dimension size could influence both components' properties.
- The report was published by Telset on 7 September 2026.
